[0001] 领域 [0001] field

[0002] 本申请一般涉及无线通信,尤其涉及用于密集无线环境中的频分复用无线通信的系统、方法和设备。 [0002] The present application relates generally to wireless communications, and more particularly for dense wireless environments frequency division multiplexing wireless communication system, method and apparatus.

背景技术 Background technique

[0003] 在许多电信系统中,通信网络被用于在若干个空间上分开的交互设备之间交换消息。 [0003] In many telecommunication systems, communication networks are used to exchange messages between the plurality of spatially separate interactive device. 网络可根据地理范围来分类,该地理范围可以例如是城市区域、局部区域、或者个人区域。 According to the geographical scope of the network to classify the geographic scope may, for example, urban areas, local area, or personal area. 此类网络可分别被指定为广域网(WAN)、城域网(MAN)、局域网(LAN)、无线局域网(WLAN)、或个域网(PAN)。 Such networks may be designated respectively as a wide area network (WAN), metropolitan area network (MAN), Local Area Network (LAN), wireless local area network (WLAN), or a personal area network (PAN). 网络还根据用于互连各种网络节点和设备的交换/路由技术(例如,电路交换相对于分组交换)、用于传输的物理介质的类型(例如,有线相对于无线)、和所使用的通信协议集(例如,网际协议套集、SONET (同步光学联网)、以太网等)而有所不同。 Also according to the network interconnecting the various network nodes and equipment switching / routing techniques (e.g., with respect to the packet switching circuit switched), for the type of physical medium for transmission (e.g., with respect to wireless wired), and used set of communication protocols (for example, the Internet protocol suite set, SONET (synchronous optical network), Ethernet, etc.) vary.

[0004] 当网络元件是移动的并由此具有动态连通性需求时,或者在网络架构以自组织(ad hoc)拓扑结构而非固定拓扑结构来形成的情况下,无线网络往往是优选的。 [0004] When the network element is removable and thus dynamic connectivity needs, or in the case of self-organizing network architecture (ad hoc) topology rather than a fixed topology to form a wireless network is often preferred. 无线网络使用无线电、微波、红外、光等频带中的电磁波以非制导传播模式来采用无形的物理介质。 Wireless networks use radio frequency band electromagnetic waves, microwaves, infrared light and other non-guided propagation mode to use invisible physical media. 在与固定的有线网络相比较时,无线网络有利地促成用户移动性和快速的现场部署。 In comparison with the fixed wired network, wireless networks enabling users to facilitate mobility and rapid field deployment.

[0049] 促成从AP 104至一个或多个STA 106的传输的通信链路可被称为下行链路(DL) 108,而促成从一个或多个STA 106至AP 104的传输的通信链路可被称为上行链路(UL) 110。 [0049] facilitates transmission from AP 104 to a plurality of transmission or communication link STA 106 may be referred to as a downlink (DL) 108, and a communication link that facilitates transmission from a transmission of one or more STA 106 to the AP 104 It may be referred to as uplink (UL) 110. 替换地,下行链路108可被称为前向链路或前向信道,而上行链路110可被称为反向链路或反向信道。 Alternatively, a downlink 108 may be referred to a front or a forward link channel, and an uplink 110 may be referred to as a reverse link or a reverse channel.

[0050] AP 104可充当基站并提供基本服务区域(BSA) 102中的无线通信覆盖。 [0050] AP 104 may act as a base station and provides basic service area (BSA) wireless communication coverage 102. AP 104连同与该AP 104相关联并使用该AP 104来通信的诸STA 106—起可被称为基本服务集(BSS)。 AP 104, together with the associated AP 104 and the AP 104 communicates using all of which may be referred to from the STA 106- basic service set (BSS). 应注意,无线通信系统100可以不具有中央AP 104,而是可以作为STA 106之间的对等网络起作用。 It should be noted, the wireless communication system 100 may not have a central AP 104, but may act as a peer network between STA 106. 相应地,本文中所描述的AP 104的功能可替换地由一个或多个STA 106来执行。 Accordingly, the AP 104 functions described herein may alternatively be provided by one or more STA 106 to perform.

[0051] 在一些方面,STA 106可被要求与AP 104相关联以向该AP 104发送通信和/或从该AP 104接收通信。 [0051] In some aspects, STA 106 may be required to be associated with the AP 104 to the AP 104 transmits a communication and / or receive communication from the AP 104. 在一个方面,用于关联的信息被包括在由AP 104作出的广播中。 In one aspect, the associated information is used by the AP 104 included in a broadcast made of. 为了接收此种广播,例如,STA 106可在覆盖区划上执行宽覆盖搜索。 In order to receive such broadcasts, for example, STA 106 can perform searches on the cover covering a wide division. 举例而言,搜索还可由STA 106通过以灯塔方式扫过覆盖区划来执行。 For example, the search can also be covered by the lighthouse swept way division performed by the STA 106. 在接收到用于关联的信息之后,STA 106可向AP 104传送参考信号,诸如关联探测或请求。 After receiving the information for association, STA 106 may transmit reference signals to the AP 104, such as a probe or association request. 在一些方面,AP 104可使用回程服务例如以与更大的网络(诸如因特网或公共交换电话网(PSTN))通信。 In some aspects, AP 104 may be used with the larger backhaul services such as network (such as the Internet or a public switched telephone network (the PSTN)) communications.

[0054] 在一些情形中,一BSA可位于其他BSA附近。 [0054] In some cases, a BSA may be located in other nearby BSA. 例如,图2A示出了其中存在多个无线通信网络的无线通信系统200。 For example, FIG. 2A shows a case where a plurality of radio communication networks of the wireless communication system 200. 如图2A所解说的,BSA 202A.202B和202C可以物理地彼此邻近。 As illustrated in FIG. 2A, BSA 202A.202B and 202C may be physically adjacent to each other. 尽管BSA 202A- 202C紧邻,但是AP 204A - 204C和/或STA 206A- 206H可以各自使用相同的频谱来通信。 Although BSA 202A- 202C close, but AP 204A - 204C and / or STA 206A- 206H may each use the same spectrum for communication. 因此,如果BSA 202C中的设备(例如,AP 204C)正在传送数据,则在BSA 202C以外的设备(例如,AP 204A-204B或STA 206A-206F)可以侦听到介质上的通信。 Thus, if the device BSA 202C (e.g., AP 204C) is transmitting data, the device (e.g., AP 204A-204B or STA 206A-206F) outside BSA 202C can listen to the communication medium.

[0055] 一般而言,使用常规802.11 协议(例如,802.1la,802.1lb,802.Hg,802.1ln 等)的无线网络在用于介质接入的载波侦听多址(CSMA)机制下操作。 [0055] In general, the use of conventional 802.11 protocol (for example, 802.1la, 802.1lb, 802.Hg, 802.1ln etc.) wireless network operation for media access at Carrier Sense Multiple Access (CSMA) mechanism. 根据CSMA,设备侦听介质并且只在介质被侦听到为空闲时进行传送。 According to CSMA, the device listens only in the medium and the medium is conveyed to the listener is idle. 因此,如果AP 204A-204C和/或STA 206A-206H根据CSMA机制来操作并且BSA 202C中的设备(例如,AP 204C)正在传送数据,则在BSA202C以外的AP 204A-204B和/或STA 206A-206F不可在介质上进行传输,即使它们是不同BSA的一部分。 Therefore, if the AP 204A-204C and / or STA 206A-206H according to CSMA mechanism operation and BSA 202C device (for example, AP 204C) is transmitting data, the outside BSA202C the AP 204A-204B and / or STA 206A- 206F can not transmit on the media, even though they are part of different BSA.

[0056] 图2A示出了此类情形。 [0056] FIG. 2A shows such situations. 如图2A所解说的,AP 204C正在介质上进行传输。 As illustrated in FIG. 2A, AP 204C is the transmission medium. 该传输被与AP 204C在相同BSA 202C中的STA 206G侦听到、并被与AP 204C在不同的BSA中的STA 206A侦听到。 The transmission is the same with AP 204C BSA 202C in STA 206G listens to, and with the AP 204C in a different BSA in STA 206A to the listener. 虽然该传输可被定址到STA 206G和/或仅仅BSA 202C中的STAjSSTA 206A却可能直到AP 204C(以及任何其他设备)不再在介质上进行传输才能够传送或接收通信(例如,去往或来自AP 204A) ο尽管未示出,但同样情况也可适用于BSA 202B中的STA 206D-206F和/或BSA 202A中的STA 206B-206C (例如,如果AP 204C进行的传输更强以使得其他STA能够侦听到介质上的该传输)。 Although this transmission may be addressed to the STA 206G and / or simply BSA 202C in STAjSSTA 206A was possible until the AP 204C (and any other devices) is no longer transmitted on the media to be able to send or receive communications (for example, to or from the AP 204A) ο Although not shown, but the same is also applicable to the case of BSA 202B STA 206D-206F, and / or the BSA 202A STA 206B-206C (for example, if the transmission were stronger AP 204C such other STA able to listen to the transmission medium).

[0057] 于是对CSMA机制的使用造成低效,因为在一BSA以外的一些AP或STA可能能够在不干扰由该BSA中的AP或STA进行的传输的情况下传送数据。 [0057] Thus resulting in inefficient use of CSMA mechanism, because a BSA than some AP or STA may be able to transfer data without interfering with the transmission of the BSA in the AP or STA conducted. 随着活跃无线设备的数量持续增长,这类低效可能开始显著地影响网络等待时间和吞吐量。 With the number of active wireless devices continues to grow, these inefficiencies may begin to significantly affect network latency and throughput. 例如,显著的网络等待时间问题可能出现在公寓楼内,其中每个公寓单元都可包括接入点及相关联的站。 For example, a significant network latency issues that may occur in the apartment building where each apartment unit can include access points and associated stations. 事实上,每个公寓单元都可包括多个接入点,因为住户可拥有无线路由器、具有无线媒体中心能力的视频游戏控制台、具有无线媒体中心能力的电视机、能够像个人热点那样工作的蜂窝电话、和/或类似物。 In fact, each apartment unit can include a plurality of access points, because the household can have a wireless router, a wireless media center capabilities of video game consoles, media center with wireless capability of television to work as personal hotspot as cellular telephone, and / or the like. 于是纠正CSMA机制的此类低效对于避免等待时间和吞吐量问题和总体用户不满而言会是至关重要的。 So correct CSMA mechanism to avoid such inefficient latency and throughput problems and dissatisfaction in terms of overall user will be crucial.

[0058] 这些等待时间和吞吐量问题可能不限于居住区域。 [0058] The latency and throughput problems may not be limited to residential areas. 例如,多个接入点可位于机场、地铁站、和/或其他人群密集的公共空间。 For example, multiple access points may be located in airports, subway stations, and / or other crowded public space. 当前,可以在这些公共空间中提供WiFi接入,但要收费。 Currently, these can provide WiFi access in the public space, but will be charged. 如果不纠正由CSMA机制造成的此类低效,则无线网络的运营商可能由于收费和较低的服务质量开始超过任何益处而失去客户。 If you do not correct such inefficiencies caused by the CSMA mechanism, the wireless network operator may be due to charges and lower quality of service than any benefits begin to lose customers.

[0059] 因此,本文所描述的高效率802.11协议可允许设备在使这些低效得以最小化并增加网络吞吐量的经修改的机制下操作。 [0059] Thus, the high efficiency of the 802.11 protocol described herein allows the device under these inefficiencies are minimized and increase network throughput modified operating mechanism. 此种机制在以下关于图2B、3和4来描述。 Such mechanisms are described in the following with respect to FIG. 2B, 3 and 4. 高效率802.11协议的附加方面在以下关于图5-13来描述。 An additional aspect of efficient 802.11 in the following described with respect to FIG. 5-13.

[0060] 图2B示出了其中存在多个无线通信网络的无线通信系统250。 [0060] Figure 2B shows a case where a plurality of radio communication networks of the wireless communication system 250. 不像图2A的无线通信系统200,无线通信系统250可以按照本文讨论的高效率802.11标准来操作。 Unlike FIG. 2A, the radio communication system 200, a wireless communication system 250 may be operated in accordance with the high efficiency of the 802.11 standard discussed herein. 无线通信系统250 可包括AP 254A、AP 254B 和AP 254C。 The wireless communication system 250 can include AP 254A, AP 254B and AP 254C. AP 254A 可以与STA 256A-256C 进行通信,AP 254B可以与STA 256D-256F进行通信,而AP 254C可以与STA 256G-256H进行通信。 AP 254A may communicate STA 256A-256C, AP 254B STA 256D-256F may perform communication with the AP 254C may communicate STA 256G-256H.

[0061] 可以将各种过程和方法用于无线通信系统250中在AP 254A-254C与STA256A-256H之间的传输。 [0061] The various processes and methods can be used in a wireless communication system 250 for transmission between AP 254A-254C and the STA256A-256H. 例如,可以根据0FDM/0FDMA技术或CDMA技术来在AP 254A-254C和STA 256A-256H之间发送和接收信号。 For example, you can send and receive signals between the AP 254A-254C and STA 256A-256H according 0FDM / 0FDMA technology or CDMA technology.

[0062] AP 254A可充当基站并提供BSA 252A中的无线通信覆盖。 [0062] AP 254A may act as a base station and provides wireless communication coverage of BSA 252A. AP 254B可充当基站并提供BSA 252B中的无线通信覆盖。 AP 254B may act as a base station and provides wireless communication coverage of BSA 252B. AP 254C可充当基站并提供BSA 252C中的无线通信覆盖。 AP 254C can act as a base station and provides wireless communication coverage of BSA 252C. 应当注意,每个BSA 252A、252B和/或252C可以不具有中央AP 254A、254B或254C,而是可允许STA 256A-256H中的一个或多个之间的对等通信。 It should be noted that each BSA 252A, 252B and / or 252C may not have a central AP 254A, 254B or 254C, but may allow for the STA 256A-256H between one or more peer communications. 因此,本文所描述的AP254A-254C的功能可替换地由STA 256A-256H中的一个或多个来执行。 Therefore, AP254A-254C features described herein may be replaced by the STA 256A-256H one or more of the execution.

[0063] 在一实施例中,AP 254A-254C和/或STA 256A-256H包括高效率无线组件。 [0063] In one embodiment, AP 254A-254C, and / or STA 256A-256H includes a high efficiency of the radio components. 如本文所描述的,高效率无线组件可使得能够使用高效率802.11协议来在AP与STA之间进行通信。 As described herein, the high efficiency of wireless components may enable efficient use of 802.11 protocols to communicate between the AP and the STA. 具体而言,高效率无线组件可使得AP 254A-254C和/或STA 256A-256H能够使用使CSMA机制的低效得以最小化的经修改的机制(例如,使得能够在不会发生干扰的情况下在介质上进行并发通信)。 Specifically, the assembly may be such that high efficiency of the radio and / or STA 256A-256H can be used to make the CSMA mechanism inefficient mechanism minimized modified (e.g., in the case where such interference can not occur in the AP 254A-254C concurrent communications on the media). 高效率无线组件以下关于图4来更详细地描述。 Efficient wireless module described in more detail with respect to FIG.

[0064] 如图2B中所解说的,BSA 252A - 252C物理地位于彼此邻近。 [0064] as illustrated in FIG. 2B, BSA 252A - 252C physically located adjacent to each other. 当例如AP 254A和STA 256B正在彼此通信时,该通信可被BSA 252B - 252C中的其他设备侦听到。 When, for example AP 254A and STA 256B are communicating with each other, the communication may be BSA 252B - 252C other device listens to. 然而,该通信可能只干扰某些设备,诸如STA 256F和/或STA 256G。 However, this communication may only interfere with some devices, such as STA 256F and / or STA 256G. 在CSMA下,AP 254B不会被允许与STA 256E进行通信,即使这种通信不会干扰AP 254A与STA 256B之间的通信。 In CSMA, AP 254B will not be allowed to communicate with the STA 256E, even if the traffic does not interfere with communication between the AP 254A and the STA 256B. 由此,高效率802.11协议在经修改的机制下操作,该经修改的机制在能够并发地通信的设备与不能并发地通信的设备之间进行区分。 Thus, the high efficiency at 802.11 modified operating mechanism, the mechanism can be modified between the device and the device can not communicate concurrently concurrently communicating distinguish. 在本文所使用的各种实施例中,“并发”可意指在时间上至少部分地交叠。 In various embodiments, as used herein, the term "concurrency" can mean at least partially overlap in time. 此类设备归类可由AP 254A-254C和/或STA 256A-256H中的高效率无线组件来执行。 Such devices may be classified AP 254A-254C, and / or the STA 256A-256H wireless components to perform high efficiency.

[0065] 在一实施例中,对设备是否能与其它设备并发地通信的判定基于该设备的“位置”。 [0065] In one embodiment, the device can determine whether other devices concurrently communicate with based on the device's "position." 例如,位于BSA“边缘”附近的STA可能处在使得该STA无法与其他设备并发地通信的状态或状况中。 For example, located BSA "edge" may be in the vicinity of the STA STA can not make the situation with the state or other devices to communicate concurrently. 如图2B所解说的,STA 206A、206F和206G可以是处在其中它们无法与其它设备并发地通信的状态或状况的设备。 As illustrated in FIG. 2B, STA 206A, 206F and 206G may be in the equipment and where they do not state or condition other devices concurrently communicating. 同样,位于BSA中心附近的STA可能处在使得该STA能与其他设备进行通信的状态或状况中。 Also located near the center of the BSA so that the STA STA may be in other devices with the state or condition of communication. 如图2B中所解说的,STA 206B、206C、206D、206E和206H可以是处在其中它们能与其他设备并发地通信的状态或状况中的设备。 As illustrated in FIG. 2B, STA 206B, 206C, 206D, 206E and 206H may be a device in which they state or condition and other communication devices concurrently in. 注意,设备分类不是永久的。 Note that the device classification is not permanent. 各设备可以在处在使它们能并发地通信的状态或状况与处在使它们不能并发地通信的状态或状况之间转变(例如,设备可以在运动中时、在与新AP进行关联时、在解除关联时等改变状态或状况)。 Each device can be in so that they can be complicated by a state or condition to communicate with them in the transition between the state or condition not to communicate concurrently (for example, the device can be in motion when the new AP and associates, other changes state or condition at the time of disassociation).

[0066] 如本文所使用的,设备可基于物理位置、无线电“位置”(例如,射频特性)、或其组合而被分类为“边缘”设备。 [0066] As used herein, may be based on the physical location of the device, the radio "position" (e.g., RF characteristics), or a combination thereof and are classified as "edge" device. 例如,在所解说的实施例中,STA 256B可物理地靠近AP 254A。 For example, in the illustrated embodiment, STA 256B may be physically close to the AP 254A. 相应地,STA 256B可基于其物理邻近于AP 254A而被分类为蜂窝小区内设备(即,并非“边缘”设备)。 Accordingly, STA 256B may be based on their physical proximity to the AP 254A and is classified as a device within the cell (ie, not "edge" device). 具体而言,STA 256B可以很可能成功地与AP 254A通信,即使在STA 256G正并发地传送时。 Specifically, STA 256B can be successfully AP 254A may communicate with, even in the STA 256G being concurrently transmitted time.

[0067] 另一方面,STA 256C可以物理地靠近AP 254A,但其天线可能取向为不足以用于与AP 254A通信。 [0067] On the other hand, STA 256C may be physically close to the AP 254A, but it is insufficient for the antenna may be oriented to communicate with the AP 254A. 例如,STA 256C可能具有指向STA 256G的方向天线。 For example, STA 256C may have a directional antenna pointing STA 256G. 相应地,虽然STA256C可能物理地靠近AP 254A,但其因相对于AP 254A的不足RF特性而被分类为边缘设备。 Accordingly, although STA256C may be physically close to the AP 254A, but due to its relative lack of RF characteristics AP 254A is classified as an edge device. 换言之,STA 256C在STA 256G正并发地传送时或许不太可能成功地与AP 254A通信。 In other words, perhaps unlikely to communicate successfully when the STA 256C being transmitted concurrently with the STA 256G AP 254A.

[0068] 在另一示例中,STA 256A可能物理地靠近AP 254A,但其可能还物理地靠近STA256G。 [0068] In another example, STA 256A may be physically close to the AP 254A, but it may also be physically close to STA256G. 由于STA 256A与STA 256G之间的邻近,STA 256A在STA 256G正并发地传送时或许不太可能成功地与AP 254A通信。 Due to its proximity STA 256A and between the STA 256G, STA 256A perhaps unlikely to successfully communicate with the AP 254A STA 256G while being concurrently transmitted. 在此实施例中,STA 256A可能也被表征为边缘设备。 In this embodiment, STA 256A may also be characterized as an edge equipment.

[0069] 在各种实施例中,影响STA被表征为蜂窝小区内设备或蜂窝小区边缘设备的RF特性包括以下一者或多者:信号对干扰加噪声比(SINR)、RF几何学、收到信号强度指示符(RSSI)、调制和编码方案(MCS)值、干扰电平、信号电平,等等。 [0069] In various embodiments, the STA affect the RF characteristics is characterized as a cell or a cell edge device comprising the apparatus of one or more of: signal-to-interference plus noise ratio (an SINR), RF geometry, close the signal strength indicator (RSSI), modulation and coding scheme (MCS) value, interference level, signal level, and so on. 在各种实施例中,一个或多个物理和RF特性可与一个或多个阈值水平进行比较。 In various embodiments, one or more physical and RF characteristics with a threshold level or more compared. 该比较可被加权和/或组合。 The comparison may be weighted and / or combinations thereof. 在各种实施例中,设备可基于单独的、加权的和/或组合的物理和RF特性以及相关联的阈值而被确定为处于使得它们能或不能并发地通信。 In various embodiments, the device may be a single, weighted, and / or a combination of physical and RF characteristics, as well as the associated threshold is determined to be in so that they can or can not communicate concurrently.

[0070] 设备可被配置成基于它们是否是处在与其他设备并发地通信的状态或状况中的设备而有不同的行为。 [0070] The device may be configured based on whether they are in communication with other devices concurrently the state or condition of the equipment have different behavior. 例如,处在使其能并发地通信的状态或状况中的设备(其在本文中可被称为“蜂窝小区内”设备)可以在相同的频谱内通信。 For example, in the state or condition so that it can concurrently communicating device (which may be referred to as "the cell" herein devices) can communicate in the same frequency spectrum. 然而,处在使其不能并发地通信的状态或状况中的设备(其在本文中可被称为“蜂窝小区边缘”设备)可采用某些技术(诸如空间复用或频域复用)以便于在该介质上通信。 However, it can not concurrently communicate in the state or condition of the device (which may be referred to as "cell edge" device herein) may be some techniques (such as spatial multiplexing or frequency domain multiplexed) to the communication on the medium. 对设备行为的控制可由AP 254A-254C和/或STA 256A-256H中的高效率无线组件来执行。 Behavior control device by AP 254A-254C and / or STA 256A-256H of the high efficiency of the radio components to perform.

[0071] 在一实施例中,蜂窝小区边缘设备使用空间复用技术来在介质上通信。 [0071] In one embodiment, the cell edge device uses spatial multiplexing to communicate on the media. 例如,功率和/或其它信息可以嵌入在由另一设备传送的分组的前置码内。 For example, the power and / or other information may be embedded in another device packet transmitted by the preamble. 当在介质上侦听到分组时,处在使其不能并发地通信的状态或状况的设备可以分析前置码,并基于规则集来决定是否要进行传输。 When the media listens to the packet, you can not concurrently in communication with the state or condition of equipment can analyze a preamble, and based on the rule set to decide whether you want to transfer.

[0072] 在另一实施例中,蜂窝小区边缘设备使用频域复用技术来在介质上通信。 [0072] In another embodiment, the cell edge devices communicate using frequency domain multiplex technique on a medium. 例如,在一个实施例中,第一蜂窝小区边缘设备子集可使用第一可用带宽子集来通信。 For example, in one embodiment, the first cell edge device using the first subset of the subset of the available bandwidth for communication. 第二蜂窝小区边缘设备子集可使用第二可用带宽子集来通信。 The second cell edge device using the second subset of the subset of the available bandwidth for communication. 同时,蜂窝小区内设备可使用全部可用带宽或第三可用带宽子集来通信。 At the same time, the cell can use all the available bandwidth of the device or a third subset of the available bandwidth for communication. 在各种实施例中,第三子集可大于第一和/或第二子集。 In various embodiments, the third subset may be greater than the first and / or second subset. 在一些实施例中,第三子集可与第一和/或第二子集交叉。 In some embodiments, the third subset may intersect with the first and / or second subset. 在一些实施例中,第三子集可包括所有可用带宽(例如,根据特定技术(诸如802.11)被许可使用的所有带宽)。 In some embodiments, the third subset may include all available bandwidth (for example, are licensed to use all the bandwidth according to a specific technique (such as 802.11)). 尽管信道、子信道、可用带宽及其子集在本文中一般被描绘为毗连的,但本领域普通技术人员将领会本文所使用的术语还可涵盖毗连频率、交织频率、具有或不具有跳频的毗邻或非毗邻频调集合。 Although the channel, subchannel, and a subset of the available bandwidth is generally depicted herein as contiguous, those of ordinary skill will appreciate that the term as used herein also covers the adjacent frequency, frequency interleaving, with or without frequency hopping adjacent or non-adjacent to the tone set.

[0073] 例如,继续参照图2B,STA 256A、256C和256G可以是蜂窝小区边缘设备,而STA256B和256H可以是蜂窝小区内设备。 [0073] For example, continued reference to FIG 2B, STA 256A, 256C and 256G may be a cell edge equipment, and STA256B and 256H may be a cell within the device. 相应地,在一实施例中,STA 256A和256C可形成第一蜂窝小区边缘设备子集,其被配置成在第一子信道(或子信道集)上与AP 254A通信。 Accordingly, in one embodiment, STA 256A and 256C may be formed of the first subset cell edge device, which is configured in a first subchannel (or subchannels) to communicate with the AP 254A. 第一蜂窝小区边缘设备子集可与第一BSA 252A相关联。 The first edge device cell subset may be associated with a first BSA 252A. STA 256G可形成第二蜂窝小区边缘设备子集,其被配置成在可与第一子信道正交的第二子信道(或子信道集)上与AP 254C通信。 STA 256G may be formed of the second subset cell edge device, configured to communicatively first subchannel in a second orthogonal subchannel (or subchannels) and with the AP 254C. 第二蜂窝小区边缘设备子集可与第二BSA 252C相关联。 The second cell edge devices may be associated with a subset of the second BSA 252C. 因此,在一实施例中,STA256A可以与STA 256G同时地(但在不同子信道上)通信。 Thus, in one embodiment, STA256A may (but on different sub-channels) simultaneous communication with STA 256G.

[0074] 同时,STA 256B可使用第三子信道与AP 254A通信,并且STA 256H可使用第三子信道与AP 254C通信。 [0074] Meanwhile, STA 256B can be used to communicate with the third sub-channel 254A AP, and STA 256H can be used to communicate with the third subchannel AP 254C. 因此,STA 256B可以与STA 256H同时地(但在至少部分交叠的信道上)通信。 Accordingly, STA 256B may (but at least partially overlapping channels) simultaneous communication with STA 256H. 由于STA 256B和STA 256H是蜂窝小区内设备,因此它们不太可能彼此干扰。 Since STA 256B and STA 256H within cell devices, so they are less likely to interfere with each other. 在各种实施例中,STA 256B和STA 256H还可在不同的交叠或不交叠的子信道上通信。 In various embodiments, STA 256B and STA 256H can also communicate on different subchannels overlapping or non-overlapping.

[0075] 在一些实施例中,每个BSA中的一个或多个设备可协调频率使用和重用,从而降低或最小化干扰的机会。 [0075] In some embodiments, each of BSA, one or more devices may coordinate frequency use and reuse, reducing or minimizing the chance of interference. 例如,第一BSA 252A中的一个或多个设备可向第一和/或第二BSA 252A和/或252C中的一个或多个设备传送指令,从而标识供蜂窝小区边缘设备在BSA252A和252C中的一者或两者中使用的子信道。 For example, the first BSA 252A one or more devices may apply to the first and / or second BSA 252A and / or 252C in one or more devices transmit instructions to identify and 252C for BSA252A the cell edge devices one or both of the subchannels used. 例如,AP 254A可指令STA 256A使用特定子信道,并且随后可指令STA 256A使用另一子信道。 For example, AP 254A may instruct the STA 256A using a particular subchannel, and may then use another command STA 256A subchannels. 同样,AP 254A可指令STA 256G使用特定子信道,并且随后可指令STA 256G使用另一子信道。 Similarly, AP 254A may instruct the STA 256G using a particular subchannel, and may then use another command STA 256G subchannels.

[0076] 在另一实施例中,第一BSA 252A中的蜂窝小区边缘设备可简单地开始使用第一子信道(或子信道集)。 [0076] In another embodiment, the first cell in the BSA 252A edge device may simply use a first start subchannel (or subchannels). 例如,第一BSA 252A中的蜂窝小区边缘设备可基于一个或多个RF特性来选择第一子信道,诸如具有最少干扰的子信道或子信道集。 For example, the first cell BSA 252A of the edge devices may be based on one or more selected first subchannel RF characteristics, such as having the least interference subchannel or subchannels. 第二BSA 252C中的蜂窝小区边缘设备可观察到第一子信道的使用并且可选择第二子信道(或子信道集)。 BSA 252C in the second cell to the first edge of the device was observed using subchannel and optionally a second subchannel (or subchannels). 例如,第一子信道上的新干扰可导致第二BSA 252C中的蜂窝小区边缘设备选择第二子信道。 For example, the new first subchannel interference on the second BSA 252C can result in cell edge device selects the second subchannel.

[0077] 在一些实施例中,频率使用和重用可以是未经协调的。 [0077] In some embodiments, the frequency of use and reuse may be uncoordinated. 例如,蜂窝小区边缘设备可被配置成在调度、随机或伪随机基础上在子信道之间跳跃。 For example, cell edge device may be configured to schedule, on the basis of a random or pseudo-random hopping between sub-channels. 因此,STA 256A可使用特定的子信道达第一时间段,并且可随后使用另一子信道。 Accordingly, STA 256A may use a particular subchannel of a first period of time, and can then use another subchannel. 同样,STA 256G可使用特定的子信道达第一时间段,并且可随后使用另一子信道。 Similarly, STA 256G particular subchannel can be used for a first period of time, and can then use another subchannel. 在一些情形中,STA 256A和256G可能偶尔跳跃到相同子信道。 In some cases, STA 256A and 256G may occasionally jump to the same subchannel. 然而,它们还有可能不时地在不同信道上进行传送。 However, from time to time they may also be transmitted on different channels.

[0078] 图3示出了可在图1的无线通信系统100和图2B的无线通信系统250内采用的频率复用技术。 [0078] FIG. 3 shows the frequency multiplexing in a wireless communication system of FIG. 1, a wireless communication system 100 and 250 of FIG. 2B used. 如图3所解说的,在无线通信系统300内可以存在AP 304A、304B、304C和304D。 As illustrated in Figure 3, within a wireless communication system 300 may exist AP 304A, 304B, 304C and 304D. AP 304A、304B、304C和304D中的每一个都可以与不同的BSA相关联并且包括本文所描述的高效率无线组件。 AP 304A, 304B, 304C and 304D each of which may be associated with different high efficiency of BSA and include wireless components described herein.

[0079] 作为示例,通信介质的可用带宽可被特许机构、标准机构设置,或者由设备预设或检测。 [0079] As an example, the available bandwidth of the communication medium can be chartered institutions, standard setting bodies, or preset or detected by the device. 例如,在802.11标准中,可用带宽可以为80MHz。 For example, in the 802.11 standard, the available bandwidth may be 80MHz. 在旧式802.11协议下,AP 304A、304B、304C和304D中的每一个以及与每个相应AP相关联的STA尝试使用整个带宽来进行通信,这可减少吞吐量。 In legacy 802.11, AP 304A, 304B, 304C and 304D each STA in each respective AP and associated attempts to use the entire bandwidth to communicate, which can reduce throughput. 在一些实例中,每个相应AP可保留整个带宽,同时实际上仅在可用带宽的子集上通信。 In some examples, each respective AP may retain the entire bandwidth, while in fact only a subset of the available bandwidth of the communication. 例如,旧式信道可具有20MHz的带宽。 For example, the old channel may have a 20MHz bandwidth. 然而,在使用频域复用的高效率802.11协议下,带宽可被划分成多个子信道。 However, in the frequency domain multiplexing efficient 802.11 protocol, bandwidth is divided into multiple sub-channels. 在图3中所解说的实施例中,例如,80MHz的可用带宽被划分成四个20MHz的段308、310、312和314(例如,信道)。 In the embodiment illustrated in Figure 3 as in, for example, 80MHz bandwidth available has been divided into four 20MHz of 308,310, 312 and 314 (for example, channel). AP 304A可以与段308相关联,AP 304B可以与段310相关联,AP 304C可以与段312相关联,而AP 304D可以与段314相关联。 AP 304A may be associated with the segment 308, AP 304B may be associated with the segment 310, AP 304C is associated with segment 312, and segment 314 AP 304D may be associated. 在各种实施例中,可使用其他大小的子信道。 In various embodiments, other sizes may be used subchannels. 例如,子信道可在约IMHz与40MHZ之间,约2MHz与1MHz之间,具体而言为约5MHz。 For example, the subchannel may be between about IMHz and 40MHZ, between about 2MHz and 1MHz, specifically about 5MHz. 如以上所讨论的,子信道可以是毗连或非毗连的(例如,交织的)。 As discussed above, the subchannel may be contiguous or non-contiguous (e.g., interlaced).

[0080] 在一实施例中,当AP 304A-304D以及处在使得STA能与其它设备并发地通信的状态或状况的这些STA(例如,在BSA的中心附近的STA)正在彼此通信时,则每个AP304A-304D以及这些STA中的每一个STA都可使用80MHz介质中的部分或全部来进行通信。 [0080] In one embodiment, when the AP 304A-304D in time and so that these can STA STA state or condition and other communication devices concurrently (e.g., in the vicinity of the center of the STA BSA) are communicating with each other, then each of these AP304A-304D and each STA STA 80MHz can use some or all of the media to communicate. 然而,当AP 304A-304D以及处在使得STA不能与其它设备并发地通信的状态或状况的这些STA (例如,在BSA的边缘附近的STA)正在彼此通信时,AP 304A及其STA使用20MHz段308来进行通信,AP 304B及其STA使用20MHz段310来进行通信,AP 304C及其STA使用20MHz段312来进行通信,而AP 304D及其STA使用20MHz段314来进行通信。 However, when the AP 304A-304D in time and not the STA STA such state or condition of other devices concurrently communicate (e.g., in the vicinity of the edge of BSA STA) are communicating with each other, AP 304A and the STA uses 20MHz segment 308 to communicate, AP 304B STA uses 20MHz section 310 and to communicate, AP 304C segments 312 and STA uses the 20MHz to perform communication using the STA and AP 304D 20MHz section 314 for communication. 因为段308、310、312和314是通信介质的不同部分,所以使用第一段的第一传输不会干扰使用第二段的第二传输。 Because the segments 308,310, 312 and 314 are different portions of a communication medium, use of the first segment of the second segment of the first transmission does not interfere with the use of a second transmission.

[0081] 因此,包括高效率无线组件的AP和/或STA,甚至处于使得它们不能与其它设备并发通信的状态或状况的那些AP和/或STA,可与其它AP和STA并发地通信而不产生干扰。 [0081] Thus, the assembly including a high efficiency wireless AP and / or STA, so that they can not even be in a state or condition that AP and other concurrent communication device and / or STA, the AP and the other can not concurrently communicate with STA interference. 相应地,无线通信系统300的吞吐量可以增加。 Accordingly, the throughput of the wireless communication system 300 may be increased. 在公寓楼或人群密集的公共空间的情况下,使用高效率无线组件的AP和/或STA甚至可以随着活跃无线设备的数量增加而经历减少的等待时间和增加的网络吞吐量,由此改善用户体验。 In the case of apartment buildings or crowded public space, using high-efficiency wireless components of AP and / or STA may even increase as the number of active wireless devices and experience to reduce latency and increase network throughput, thereby improving user experience.

[0084] 处理器404可包括用一个或多个处理器实现的处理系统或者可以是其组件。 [0084] Processor 404 may include one or more processors to implement the processing system or may be a component thereof. 这一个或多个处理器可以用通用微处理器、微控制器、数字信号处理器(DSP)、现场可编程门阵列(FPGA)、可编程逻辑器件(PLD)、控制器、状态机、选通逻辑、分立硬件组件、专用硬件有限状态机、或能够对信息执行演算或其他操纵的任何其他合适实体的任何组合来实现。 The one or more processors may be a general purpose microprocessor, a microcontroller, a digital signal processor (DSP), field programmable gate arrays (the FPGA), programmable logic devices (PLD), controllers, state machines, sorting through logic, discrete hardware components, dedicated hardware finite state machine, or be able to perform calculations or any other information in any combination with other appropriate entities manipulated to achieve.

[0091] 无线设备402的各种组件可由总线系统426耦合在一起。 [0091] The various components of the wireless device 402 are coupled together by a bus system 426. 总线系统426可包括例如数据总线,以及除了数据总线之外还有电源总线、控制信号总线和状态信号总线。 System bus 426 may include a data bus, a data bus, and there is in addition to the power bus, a control signal bus, and status signal bus. 本领域技术人员将领会,无线设备402的各组件可耦合在一起或者使用某种其他机制来接受到彼此的输入或向彼此提供输入。 Those skilled in the art will appreciate that various components of the wireless device 402 may be coupled together, or use some other mechanism to receive input from each other or one another to provide input.

[0092] 尽管图4中解说了数个分开的组件,但本领域技术人员将认识到,这些组件中的一个或多个组件可被组合或者共同地实现。 [0092] Although Figure 4 illustrates a number of separate components, those skilled in the art will recognize that these components of one or more components may be combined or implemented collectively. 例如,处理器404可被用于不仅实现以上关于处理器404描述的功能性,而且还实现以上关于信号检测器418和/或DSP 420描述的功能性。 For example, the processor 404 may be used not only to achieve the above description about the processor's 404 functionality, but also to achieve the above on signal detector 418 and / or the DSP 420 described functionality. 另外,图4中解说的每个组件可使用多个分开的元件来实现。 In addition, each component illustrated in Figure 4 can use a plurality of separate elements to achieve.

[0093]无线设备 402 可包括AP 104、STA 106、AP 254、STA 256 和/ 或AP 304,并且可用于传送和/或接收通信。 [0093] The wireless device 402 may include AP 104, STA 106, AP 254, STA 256 and / or AP 304, and may be used to transmit and / or receive communication. 即,AP 104,STA 106,AP 254,STA 256或AP 304可用作发射机或接收机设备。 That is, AP 104, STA 106, AP 254, STA 256 or AP 304 can be used as a transmitter or receiver device. 某些方面构想了信号检测器418由在存储器406和处理器404上运行的软件用来检测发射机或接收机的存在。 Certain aspects contemplated by the signal detector 418 running on processor 406 and memory 404 software is used to detect the presence of a transmitter or receiver.

[0094] 图5A示出了其中可采用本公开的各方面的无线通信系统500。 [0094] FIG. 5A shows an example in which the present disclosure may be employed in all aspects of the wireless communication system 500. 如图5A所解说的,无线通信系统500包括BSA 502。 Illustrated in FIG. 5A, the radio communication system 500 comprises a BSA 502. BSA 502可包括AP 504和STA 506A - 506E。 BSA 502 may include an AP 504 and STA 506A - 506E. 在一实施例中,AP 504和STA 506A- 506D各自包括以上所讨论的高效率无线组件。 In one embodiment, AP 504 and STA 506A- 506D each include a wireless module efficiency discussed above. 然而,STA 506E不包括高效率无线组件。 However, STA 506E does not include the high efficiency of the radio components. 因此,STA 506A - 506D被称为高效率STA,而STA 506E被称为旧式STA(例如,因为其与常规IEEE 802.11协议(诸如IEEE 802.lln、IEEE 802.1lac等)兼容)。 Accordingly, STA 506A - 506D are referred to as high-efficiency the STA, and the STA STA 506E are called legacy (e.g., because it is compatible with conventional IEEE 802.11 protocol (such as IEEE 802.lln, IEEE 802.1lac etc.)).

[0095] 在一些实施例中,旧式STA 506E将保留整个可用带宽(例如,80MHz),同时经由旧式信道(例如,20MHz)向旧式AP (其不包括高效率无线组件)进行传送。 [0095] In some embodiments, the legacy STA 506E will retain the entire available bandwidth (e.g., 80MHz), while via a legacy channel (e.g., 20MHz) to transmit to the legacy AP (which does not include a high efficiency of the radio components). 在一实施例中,高效率AP 504可被配置成同时在多个子信道上接收数据。 In one embodiment, the high efficiency AP 504 may be configured to simultaneously receive data on a plurality of subchannels. 例如,STA 506A可经由上行链路(UL)通信510向AP 504进行传送,STA 506B可经由上行链路(UL)通信512向AP 504进行传送,并且STA 506C可与STA 506E经由上行链路(UL)通信518向AP 504进行传送同时地经由上行链路(UL)通信514向AP 504进行传送。 For example, STA 506A to the AP 504 can perform communication 510 via an uplink (UL) transmission, STA 506B communicatively 512 to AP 504 is transmitted via an uplink (UL), and with STA 506E STA 506C via an uplink ( UL) communication 518 to the AP 504 to transmit simultaneously (UL) communication 514 is transmitted to the AP 504 via the uplink. 在所解说的实施例中,UL通信518可以是旧式信道通信,并且UL通信510、512和514可以是占据未使用的可用子信道的高效率信道通信。 In the embodiment illustrated in, UL 518 may be a legacy communication channel communication, communication and UL 510, 512 and 514 may be available sub-channels occupy unused efficient channel of communication. 在一实施例中,STA 506D也可经由UL通信516向AP 504进行传送。 In one embodiment, STA 506D can also be transmitted to the AP 504 via the communication 516 UL. 如图5A所解说的,与STA 506D- 506E相比,STA 506A - 506C可位于更靠近AP 504。 As illustrated in Figure 5A, as compared with STA 506D- 506E, STA 506A - 506C may be located closer to the AP 504. UL通信510、512、514、516和518可由AP 504根据本文所描述的上行链路频域复用(UL FDM)协议来作出。 UL communications 510,512,514,516 and 518 by the AP 504 according to the uplink described herein frequency domain multiplexing (UL FDM) protocol to make.

[0096] UL FDM协议可包括三个数据交换阶段:⑴数据传输;⑵保护;以及(3)确收。 [0096] UL FDM data exchange protocol may include three stages: ⑴ data transmission; ⑵ protection; and (3) acknowledgment. 保护阶段可在数据传输阶段之前并且确收阶段可在数据传输阶段之后。 Protection phase may be performed before the data transfer phase and can stage acknowledgment after the data transfer phase. 在保护阶段,可采用各技术来防止干扰。 In the protection phase, various techniques can be used to prevent interference. 在数据传输阶段,一个或多个STA可向AP传送数据。 In the data transfer phase, the one or more STA may transmit data to the AP. 在确收阶段,STA可确认AP接收到了恰适的数据。 In the acknowledgment phase, STA confirmed that AP has received the appropriate appropriate data. 这些阶段中的每一个可根据本文所讨论的频域复用原理在不同信道上并发地发生。 Each of these stages can occur concurrently discussed herein according to the frequency domain multiplexing principle on different channels. 另外,UL FDM协议可包括与STA 306A- 306E(图3)作出的传输的开始的定时相关的规则。 Further, UL FDM protocol may include rules related to the timing of the start STA 306A- 306E (FIG. 3) made of the transmission.

[0097]数据传输阶段 [0097] Data transfer phase

[0098] 在UL数据传输阶段,数据由多个STA在不同信道上同时传送。 [0098] In the UL data transfer phase, data is transmitted simultaneously by a plurality of different channels STA. STA可在本文所讨论的任何信道上进行传送,尤其在可用带宽内的那些信道上。 STA may be transmitted on any channel discussed herein, particularly those channels within the available bandwidth. 在一实施例中,在数据传输阶段期间有若干数据传输选项可用。 In one embodiment, during the data transfer phase of a number of data transmission options are available. 具体而言,若干选项可用于在不同信道上分配STA以使得这些STA能并发地通信。 Specifically, several options can be used to assign different channels to make these STA STA can communicate concurrently. 这些选项还可允许旧式STA和高效率STA两者并发地通信。 These options also allow legacy STA STA and efficient communication both concurrently. 因此,本文所描述的用以改进网络吞吐量和减小等待时间的技术可在与高效率STA兼容且与现有旧式STA后向兼容的设备中实现。 Therefore, in order to improve network throughput and reducing the latency of available techniques described herein to a compatible device in the STA efficient and compatible with the existing legacy STA.

[0099] 例如,常规IEEE 802.11协议(例如,802.1ln,802.1lac等)的现有PHY层可与新媒体接入控制(MAC)机制耦合以在不同信道上分配STA。 [0099] For example, a conventional IEEE 802.11 protocol (e.g., 802.1ln, 802.1lac, etc.) with the new PHY layer existing Media Access Control (MAC) mechanism is coupled to STA allocated on different channels. 作为另一示例,新PHY层前置码可被创建以用于高效率802.11协议并且可被各STA在不同信道上使用。 As another example, the new PHY layer preamble may be used to create high efficiency 802.11 and each STA may be used in different channels. 作为另一示例,常规IEEE 802.11协议的现有PHY层和新PHY层前置码可被各STA用来同时地或基本上同时地在不同信道上传送STA。 As another example, a conventional existing IEEE 802.11 PHY layer protocol and the new PHY layer preamble for each STA may be simultaneously or substantially simultaneously transmitted on different channels STA.

[0100] 图5B - 5C示出了其中可采用本公开的各方面的时序图。 [0100] FIG. 5B - 5C illustrates the disclosure of which may be employed in all aspects of a timing diagram. 具体而言,图5B - 5C示出了可根据常规IEEE 802.11协议的现有PHY层和新MAC机制来使用的时序图。 Specifically, FIG. 5B - 5C shows a timing diagram according to the prior conventional IEEE 802.11 PHY layer protocol and the new MAC mechanism to use. 如图5B - 5C所解说的,存在四个信道(CH):信道520、信道522、信道524和信道526。 FIG. 5B - 5C are illustrated, there are four channels (CH): channel 520, channel 522, channel 524 and channel 526. 如以上所讨论的,本文所使用的术语'信道'可指代频谱的毗连部分或频谱的非毗邻区间的集合(在此情形中术语'用于信道的带宽'可指代每个区间的带宽的总和)中的任一者。 For example, the terms used herein discussed above, the 'channel' may refer to the spectrum of the adjacent portion or the spectrum of the non-adjacent intervals set (in this case the term 'for the bandwidth of the channel' may be each interval bandwidth refers the sum of) any one. 如本文所使用的,信道526被称为主信道(例如,被在常规IEEE 802.11协议上操作的STA使用的默认信道)并且信道520、522和524被称为副信道。 As used herein, the channel 526 is called the main channel (for example, STA is the default channel on a conventional IEEE 802.11 protocol operation used) and the channel 520, 522 and 524 are called side-channel. 在一些实施例中,旧式STA仅能与主信道上的传输相结合地在副信道上进行传送。 In some embodiments, the legacy STA can only transfer between the main channel and in combination in the sub-channel for transmission. 相反,在各种实施例中,HEff STA可在主信道上、在与副信道相结合的主信道上、或者在不包括主信道的情况下在副信道上进行传送。 In contrast, in various embodiments, HEff STA in the main channel in the sub-channel combination of the main channel, or in the case of not including the main channel in the sub-channel for transmission. 信道520、522、524和526可以是毗连的(例如,每个信道520、522、524和526覆盖连贯的20MHz频率范围,诸如从1000MHz到1080MHz)或非毗连的(例如,在信道520、522、524和/或526中的一者或多者之间存在频率间隙)。 Channel 520,522,524 and 526 can be contiguous (for example, each channel 520,522,524 and 526 covered coherent 20MHz frequency range, such as from 1000MHz to 1080MHz) or non-contiguous (for example, channel 520, 522 , between 524 and / or 526 in one or more of the frequency gap).

[0101] 在一个实施例中,所有传输都来自HEW STA。 [0101] In one embodiment, all transfers from HEW STA. 在另一实施例中,一个传输来自旧式STA,并且一个或多个其他传输来自一个或多个HEW STA0在各种实施例中,每个STA的传输带宽可以相同或者可以不同。 In another embodiment, a transmission from a legacy STA, and one or more other transmissions from one or more of HEW STA0 In various embodiments, each STA transmission bandwidth may be the same or may be different. 在各种实施例中,每个STA所使用的示例性带宽可包括以下一者或多者:2.5MHz、5MHz、7.5MHz、1MHz、15ΜΗζ、20ΜΗζ、30ΜΗζ、40ΜΗζ、60ΜΗζ、以及80MHz。 In various embodiments, each of the exemplary bandwidth of STA used may include one or more of the following: 2.5MHz, 5MHz, 7.5MHz, 1MHz, 15ΜΗζ, 20ΜΗζ, 30ΜΗζ, 40ΜΗζ, 60ΜΗζ, and 80MHz. 在一些实施例中,来自所有STA的传输可被分配成使得没有传输在毗邻的信道上。 In some embodiments, all transmissions from the STA can not be allocated such that adjacent transmission channels.

[0102] 在一实施例中,主信道(单独或与附加副信道相结合,例如在旧式lln/llac操作中)被用于从旧式STA(例如,STA 506E)到AP 504的通信。 [0102] In one embodiment, the primary channel (alone or in combination with additional subchannels combined, for example, in old lln / llac operation) is used from the older the STA (e.g., STA 506E) to the AP 504 of the communication. 副信道也被用于从高效率STA (例如,STA 506A - 506D)到AP 504 的通信。 Vice channel is also used for high efficiency from STA (for example, STA 506A - 506D) to the communication AP 504.

[0103] 在各种实施例中,来自多个STA的传输的历时可以相同或者可以不同。 [0103] In various embodiments, the duration of the transmission from the STA may be the same or a plurality may be different. 用于传输的不同数据量和不同数据率可导致用于每个数据的传输的不同时间。 Different amounts of data and different data rates for transmission at different times may lead to the transmission of each data. 在某些情形中,所有传输同时结束、而不论每个STA会用来发送数据的不同最小时间是有利的。 In some cases, the end of all transmissions at the same time, regardless of each STA will send the data to different minimum time is advantageous. 在所有传输同时结束的此类情形中,每个STA可将一个或多个附加填充字节包括到帧中,从而帧长度匹配目标帧长度。 In such cases all at the same time the end of the transmission, each STA may be one or more additional padding bytes including the frame, whereby the frame length to match the target frame length. 目标历时可在紧挨在传输之前接收到的帧(例如,以下关于图6A-6C描述的参考信号CTX)中指示,和/或可被先前协商或由AP指示。 Target last frame before transmission can be received immediately (for example, the following with respect to FIG. 6A-6C reference signal described CTX) indicated, and / or may be previously negotiated by the AP or instructions.

[0104] 在各种实施例中,填充操作可通过添加一个或多个聚集媒体接入控制协议数据单元(A - MPDU)子帧和/或填充字节(例如,如在IEEE 802.1lac标准中定义的)来执行。 [0104] In various embodiments, the filling operation by adding one or more aggregated medium access control protocol data unit (A - MPDU) subframes and / or padding bytes (for example, as in the standard IEEE 802.1lac ) to perform defined.

[0105] 在一实施例中,AP 504传送、并且STA 506A - 506E接收将STA 506A - 506E与信道相关联的MAC消息,由此指示AP 504计划要使用哪个信道来与相应STA 506A - 506E传达或接收通信。 [0105] In one embodiment, AP 504 transmit and STA 506A - 506E receives the STA 506A - MAC message 506E and associated channel, thereby indicating AP 504 plan to use which channel the corresponding STA 506A - 506E convey or receiving communication. 在一些实施例中,AP 504默认在主信道上与STA 506E通信,因为STA 506E是旧式STA。 In some embodiments, AP 504 by default in the main channel 506E communicate with the STA, STA 506E is because the legacy STA. 类似地,STA 506E可默认主信道用于向AP 504的传输。 Similarly, STA 506E can default to the primary channel for the AP 504 to the transmission. 因此,AP 504可以不向STA 506E传送MAC消息。 Accordingly, AP 504 may not transmit MAC message to the STA 506E. 确切而言,AP 504可以仅向高效率STA 506A - 506D传送MAC消息。 Rather, AP 504 can only to high-efficiency STA 506A - 506D transmission MAC message. 在其他实施例中,AP 504向每个STA 506A- 506E传送MAC消息。 In other embodiments, AP 504 506A- 506E transmits MAC message to each STA. 在各种实施例中,MAC消息可包括从AP 504发往STA 506A - 506D的一个或多个管理帧,并且可包括为每个STA分配的信道的指示(显式或隐式的,诸如基于分类)。 In various embodiments, MAC may include messages sent from the AP 504 to the STA 506A - 506D of one or more management frames, and may include an indication of the channel allocated to each STA (explicit or implicit, such as one based classification). 在一些实施例中,MAC消息被称为参考信号,如以下关于图7A更详细地描述的。 In some embodiments, the reference signal is called the MAC message, as described below with respect to FIG. 7A in more detail.

[0106] 信道接入 [0106] The channel access

[0107] 在各种实施例中,将STA 506A- 506E的传输的开始同步会是有益的。 [0107] In various embodiments, the STA will begin transmission 506A- 506E synchronization may be beneficial. 例如,当各传输同时开始时解码它们可以更容易。 For example, they can be more easily decoded when each transmission starts at the same time. 由于STA 506A- 506E是不同的设备,然而协调同步的传输时间可能是有挑战的。 Since STA 506A- 506E are different devices, but the transmission time of synchronization may be challenging. 在各种实施例中,传输可基于来自AP 504的恳请或未经恳请的参考信号来同步。 In various embodiments, the transmission may be based not urge or implore the reference signal from the AP 504 to synchronize. 在其他实施例中,传输可基于由AP 504和/SSTA 506A- 506E设置的调度来同步。 In other embodiments, the transmission may be based on the AP 504 and / SSTA scheduling 506A- 506E is set to synchronize.

[0108] 图6A-6C示出了其中可采用本公开的各方面的另一时序图。 [0108] FIG. 6A-6C illustrates the disclosure of which may be another timing diagram of the various aspects. 如上所述,主信道(例如,信道526)和/或副信道中的一个或多个副信道(例如,信道520、522和/或524)可被用于由旧式STA进行的传输,并且主信道和/或副信道可被用于由高效率STA进行的传输。 As described above, the primary channel (for example, 526 channels) a and / or sub-channel or a plurality of secondary channels (for example, channel 520, 522 and / or 524) may be used for transmission by the legacy STA carried out, and the main channel and / or sub-channels may be used for transmission by the STA conducted efficiently. 信道520、522、524和/或526可以是毗连或者可以是不毗连的。 520,522,524 channel and / or 526 may be contiguous or may not be contiguous. 在一实施例中,AP504可向STA 506A - 506E传送一个或多个未经恳请的参考信号CTX 601 - 604。 In one embodiment, AP504 can to STA 506A - transmitting one or more reference signals without urge CTX 601 506E - 604. 参考信号CTX 601 - 604可指示具有要发送数据的STA应当在收到之际(或者在收到后预定同步点)开始传送。 Reference signal CTX 601 - 604 may indicate that the STA having data to be transmitted should be received on the occasion (or upon receipt of a predetermined synchronization point) start the transfer. 该同步点可以例如在短帧间空间(SIFS)、点协调功能(PCF)帧间空间(PIFS)、或者CTX帧的接收结束后的另一预定义时间。 The synchronization point may for example be a short inter-frame space (SIFS), Point Coordination Function (PCF) interframe space (PIFS), or another predefined time after the end of reception of the CTX frame. 在一实施例中,接收到参考信号CTX 601 - 604的STA 506A - 506E可开始传送通信510、512、514和518。 In one embodiment, the reference signal is received CTX 601 - 604 of STA 506A - 506E may begin transmitting communications 510,512,514 and 518. 参考信号CTX 601 - 604在本文关于图7A更详细地描述。 Reference signal CTX 601 - 604 described in greater detail herein with respect to Figure 7A. 在各种实施例中,同步点可被称为联合传输时间。 In various embodiments, the synchronization point may be referred to a joint transmission time.

[0109] 如图6A所示,AP 504可在多个子信道上、或者甚至所有子信道上传送参考信号CTX 601 - 602。 [0109] As shown in Figure 6A, AP 504 may transmit a reference signal in the plurality of subchannels CTX 601, or even on all subchannels --602. 在图6A中,STA 506A - 506E仅能够在它们的获指派信道上进行接收。 In FIG. 6A, STA 506A - 506E only be eligible in their assigned channel to receive. 相应地,AP 504在所有信道上传送参考信号CTX 601 - 604。 Accordingly, AP 504 transmit a reference signal in all channels CTX 601 --604. 在一些实施例中,每个CTX可包含相同信息。 In some embodiments, each of the CTX may contain the same information. 在一些实施例中,各个CTX可在每个信道上包含不同信息。 In some embodiments, each of CTX may contain different information in each channel. 在一些实施例中,STA 506A - 506E可在任何信道上接收参考信号。 In some embodiments, STA 506A - 506E may receive a reference signal on any channel. 相应地,如图6B所示,AP 504可在能被STA 506A - 506E接收的任何子信道上(例如在主信道上)传送单个参考信号CTX 602。 Accordingly, as shown in Figure 6B, AP 504 may be STA 506A - 506E received any sub channel (e.g., the primary channel) transmits a single reference signal CTX 602.

[0110] 在图6C所示的实施例中,旧式STA 506E可以在主信道526上仅接收参考信号CTX601。 [0110] In the embodiment shown in Fig. 6C, the legacy STA 506E may only receive the reference signal CTX601 in the main channel 526. 然而,HEW STA 506A- 506C能够在任何信道上接收参考信号CTX 601。 However, HEW STA 506A- 506C CTX 601 capable of receiving a reference signal on any channel. 相应地,AP 504在主信道526上传送参考信号CTX 601。 Accordingly, AP 504 transmit a reference signal CTX 601 in the main channel 526. 在各种实施例中,STA能力的其他组合是可能的。 In various embodiments, other combinations are possible STA capability.

[0111] 一般而言,AP 504可被配置成在最小数目的子信道上传送参考信号CTX 601 -604以便于通知所有的目标STA 506A- 506E。 [0111] Generally, AP 504 may be configured to transmit a reference signal CTX 601 -604 in order to inform all target STA 506A- 506E on the minimum number of subchannels. 在一些实施例中,在不止一个子信道将满足需要的情况下,AP 504可在具有最小干扰的子信道上传送参考信号CTX 601,或者可传送一个或多个冗余参考信号CTX 601 - 604。 CTX 601 transmits a reference signal in the subchannel some embodiments, in the case where more than one sub-channel to meet the needs, AP 504 may have a minimal interference, or may transmit one or more redundant reference signals CTX 601 - 604 . 在多个子信道上传送的参考信号CTX 601 - 604可以完全相同,或者可以每子信道不同。 CTX 601 reference signal transmitted on a plurality of subchannels --604 may be identical or may be different for each subchannel.

[0112] 在一实施例中,随机退避计数器可与CTX传输信道(诸如图6C中的主信道526)相关联,如由IEEE 802.11的增强型分布式信道接入(EDCA)规程定义的。 [0112] In one embodiment, the random backoff counter may be associated with CTX transmission channels (such as in Fig. 6C main channel 526), as indicated by the IEEE 802.11 Enhanced Distributed Channel Access (EDCA) procedure definition. 当随机退避计数器期满时,AP 504可开始准备一个或多个参考信号CTX 601 - 604以供传送给STA506A - 506E。 When the random backoff counter expires, AP 504 can start to prepare one or more reference signal CTX 601 - 604 for transfer to the STA506A - 506E. 如果自随机退避计数器期满时间之前一时间段610起预期CTX传输信道已空闲,则AP 504可传送一个或多个参考信号CTX 601 - 604。 If from a random backoff time before the expiration of the time period 610 from counter expected CTX transmission channel is idle, the AP 504 may transmit one or more reference signals CTX 601 - 604. 因此,一旦随机退避计数器期满,就在主信道上作出至少一个传输。 Therefore, once the random backoff counter expires, on the main channel to make at least one transmission. 在一实施例中,时间段610可以基于PIFS时间。 In one embodiment, the time period may be based on 610 PIFS time. PIFS时间可由AP 504和/或STA 506A - 506E选择。 PIFS time by the AP 504 and / or STA 506A - 506E choice.

[0121] 在一些实施例中,AP 504和/SSTA 506A - 506E可确定STA 506A- 506E应当开始传送的调度时间。 [0121] In some embodiments, AP 504 and / SSTA 506A - 506E may determine the scheduled time STA 506A- 506E should begin transmission. 例如,调度机制可被用来定义AP 504应当期望来自STA 506A- 506E的分组的时间。 For example, the scheduling mechanism can be used to define the AP 504 should expect from the time the STA packets 506A- 506E. 一种调度机制可基于AP与每个个体STA经由管理交换商定的参考时间。 A method of scheduling mechanism based on the AP and the STA agreed each individual exchange via management reference time. 在各种实施例中,参考时间可以是周期性的、间歇的、或者随机或伪随机确定的。 In various embodiments, the reference time may be periodic, intermittent, or a random or pseudo-randomly determined. 参考时间的选择可以用协议(诸如,目标唤醒时间(TWT)定时,其在IEEE 802.1lah协议中定义)来达成。 Reference time can be used protocols (such as target wake time (TWT) the timing, which is defined in the IEEE 802.1lah Agreement) to achieve. 在一些实施例中,AP可通过为多个STA将TWT设为相同值来为多个STA定义相同的参考时间。 In some embodiments, AP by the STA to define a plurality of same reference time is set to the same value of the plurality of STA TWT. TWT定时可以是期间STA被调度为苏醒的时间。 TWT STA timing may be awake during their scheduled time. 作为另一示例,另一调度机制可以基于为一群STA定义的参考时间以及其中接入被限于该群STA的相关联的时间区间。 As another example, other scheduling mechanism based on a group of reference defined STA and wherein the access time is limited to the time interval associated with the group of the STA. 例如,此类调度可以用受限接入窗口(RAW)定时来达成,其在IEEE 802.1lah协议中定义。 For example, such a schedule may use restricted access window (RAW) timed to achieve, which is defined in the IEEE 802.1lah agreement. RAW定时可以是期间对介质的接入被限于一群STA的时间区间。 RAW timing may be during the period of access to the media is limited to a group of STA time interval. 在各种实施例中,该时间区间可进一步被时隙化并且每个时隙被指派给一个或多个STA,从而指示STA能在时隙时间开始之际传送UL数据。 In various embodiments, the time interval may further be slotted and each time slot is assigned to one or more of STA, indicating that STA can transmit UL data on the occasion of the start time of the time slot.

[0122] 在以上模式中的任一者中定义的参考时间,STA可准备好接收用于发起传输的CTX帧。 [0122] In the above mode, any one of the defined reference time, STA can CTX ready to receive frames for initiating a transmission. 在一些实施例中,STA可开始传输而无需等待CTX。 In some embodiments, STA may begin without waiting for transmission of CTX. 因此,在各种实施例中,STA可以正好在参考时间传送,或者它可以在预期传输信道上执行清除信道评估规程,在参考时间开始。 Thus, in various embodiments, the STA may transmit just a reference time, or it may perform a clear channel assessment protocol in a transmission channel is expected, started at the reference time. 在各种实施例中,信道评估可需要PIFS时间或DIFS时间。 In various embodiments, the channel may be required to assess the time PIFS or DIFS time. 如果目标信道被确定为繁忙,则STA可抑制传送。 If the target channel is determined to be busy, then the transmitting STA suppressed.

[0123] 在另一实施例中,STA可在争用空闲时段期间以HCCA模式操作。 [0123] In another embodiment, STA may be in contention during the idle period in HCCA mode. 在此情形中,STA直至CF-Poll (CF-轮询)消息被接收到(802.11)才被允许接入介质;HCCA协议可被修改以使得CF-Poll消息标识不止一个STA以用于CF-Poll帧之后的SIFS时间处的UL传输。 In this case, STA until CF-Poll (CF- polling) message is received (802.11) are allowed access to the media; HCCA protocol can be modified so that the CF-Poll message identifies more than one STA for CF- UL transmission at SIFS time after the Poll frame. CF-Poll可用本文所描述的CTX帧中的任一者替代。 CTX CF-Poll frame described herein can be used in any of a substitute.

[0124] AP 504可进一步在被用来设置调度时间的管理消息(例如,用于RAW的RPS信息元素、用于TWT的TWT设置消息等)中包括信道分配的指示以用于STA的益处。 [0124] AP 504 may further management messages are used to set the scheduled time (for example, TWT for RAW's RPS information element for TWT setting message, etc.) are included in the benefits of channel allocation instructions for the STA. 在另一实施例中,由AP 504在此类消息中指示的分配可以响应于由STA向AP 504传送的请求对特定信道的使用或简单地请求信道的分配的消息。 In another embodiment, AP 504 distribution indicated by the message in such a message in response to a request by the STA transferred to the AP 504 using a particular channel or simply request the distribution channel. 该消息可被包括在管理帧中。 The message may be included in the management frame.

[0125] 来自STA 506A - 506E的传输可在根据TWT定时或RAW定时调度的时间开始。 [0125] from STA 506A - 506E may begin transmission at the timing according to TWT or RAW regular scheduled times. 在一实施例中,随机退避计数器、PIFS定时和/SAIFS定时可如本文所描述地使用以确定信道是否已空闲达恰适时间量。 In one embodiment, the random backoff counter, PIFS timing and / SAIFS timed as described herein can be used to determine whether the channel has been idle for dacha appropriate amount of time. 基于TWT定时或RAW定时来调度传输时间的益处可以是AP504随后知晓STA 506A- 506E将在何时苏醒。 Based on the timing or RAW TWT timing scheduling transmission time benefits may be AP504 subsequently alerted STA 506A- 506E will wake up and when. 在另一实施例中,STA 506A - 506E可以不使用随机退避计数器、PIFS定时和/或AIFS定时。 In another embodiment, STA 506A - 506E may not use the random backoff counter, PIFS timing and / or timing of AIFS. 在又一实施例中,STA 506A- 506E可以不在副信道上使用PIFS定时和/或AIFS定时。 In yet another embodiment, STA 506A- 506E may not be used on the channel PIFS deputy timing and / or timing of AIFS.

[0126] 在一些实施例中,AP 504可在调度时间传送参考信号CTX 601 - 604。 [0126] In some embodiments, AP 504 may transmit a reference signal at a scheduled time CTX 601 --604. 例如,AP504可使用与STA 506A - 506E相同的调度机制(例如,TffT定时或RAW定时)来确定何时传送参考信号CTX 601 - 604。 For example, AP504 may use the STA 506A - 506E same scheduling mechanism (e.g., TffT timed or timed RAW) to determine when to transmit a reference signal CTX 601 - 604. 在一实施例中,AP 504可在侦听到预期CTX信道上介质为空闲之后传送参考信号CTX 601 - 604。 In one embodiment, AP 504 can be listening to transmit a reference signal CTX 601 CTX expected after media channel is idle --604. 在各种实施例中,AP 504可如以上关于RTX 620描述地传送参考信号CTX。 In various embodiments, AP 504 may be as described above with respect RTX 620 transmits a reference signal CTX. 在各种实施例中,CTX消息可在RAW开始时发送一次并且被用于为RAW中的所有时隙进行时间同步。 In various embodiments, CTX message may be sent once at the beginning and is used as RAW RAW all the time slots for time synchronization. 在一些实施例中,CTX可在每个时隙开始时发送,从而每传输提供同步和其他信息。 In some embodiments, CTX can be sent at the beginning of each time slot, so that each transport provider synchronization and other information.

[0143] 在一个实施例中,如果CTX消息在多个信道上发送,则以下任一者是可能的:其可作为具有横跨被分配用于UL传输的总传输BW的传输BW的单个帧来发送;其可作为跨被分配用于UL传输的所有信道的副本来发送,即,每个CTX的内容跨信道完全相同;以及其可每信道不同,从而为在不同信道上进行接收的不同STA携带不同信息。 [0143] In one embodiment, if the CTX message is sent on multiple channels, one of the any of the following are possible: it can be used as a single frame having a total transmission span allocated for UL BW of transmission of transmission BW transmitted; it can be used as across all channels allocated for UL transmission to transmit a copy, i.e., the content of each of the identical cross-CTX channel; and it may be different for each channel, so as to receive different channels of different STA carry different information. 在各种实施例中,在不同信道上发送的具有不同BW或不同信息的CTS可具有不同长度,这可与向用于UL传输的所有STA提供参考同步时间的目的形成对比。 In various embodiments, the CTS has a different BW or different information is transmitted in different channels may have different lengths, which may be linked to all the STA for UL transmission synchronization time reference object contrast. 因此,为了使所有CTS具有相同长度,每个CTX可包括数个填充字节以使得所有CTX的长度相同。 Therefore, in order to make all the CTS has the same length, each of CTX may include a number of padding bytes so that the same length of all CTX.

[0144] 在另一实施例中,CTX帧可跟随有附加“填充器”帧,其由CTX的相同发送方在SIFS时间之后发送。 [0144] In another embodiment, the frame may be followed by CTX additional "filler" frames, which are sent by the same sender CTX after SIFS time. 填充器帧可用来保持介质繁忙并且向STA提供附加时间以用于处理和解读CTX信息和用于准备后续UL传输。 Filling frames can be used to keep the media busy and STA to provide additional time for processing information and interpretation of CTX and for preparing subsequent UL transmission. 在各种实施例中,填充器帧可以是空元数据分组(NDP)、CTS、或其它控制帧中的任一者。 In various embodiments, the filler can be an empty frame metadata packets (NDP), CTS, frame or other control of any one. 填充器帧还可为即将到来的传输提供附加保护。 Filler frame also provides additional protection for the upcoming transmission.

[0145] 在各种实施例中,填充和/或填充器帧的需要或包括可由STA用关联时的指示(例如,在关联请求中)或者通过管理交换向AP指示。 [0145] In various embodiments, the filling and / or filler frame includes an indication of the need for or associated with the STA by the time (for example, in the context of the request) or by switching to the AP management instructions. STA还可指示处理所需的时间量,其可决定所需填充量。 STA can also indicate the amount of time required for the processing, which will determine the required filling amount.

[0146] 当传输是由AP用CTX发起时,有利地,AP可在其中多个STA苏醒并具有可用数据时调度传输,由此最大化效率。 [0146] When the transfer is initiated by the AP with CTX, advantageously, in which a plurality of AP STA awake and has dispatched when available data transmission, thereby maximizing efficiency. 当使用调度模式时,AP还可向STA指示没有传输被允许在调度时段之外。 When using scheduling mode, AP to STA also indicates that no transmission is allowed outside of the scheduling period. 此指示可被包括在信标中或包括在用于每个STA的设置阶段(见以下“设置”)。 This indication may be included in a beacon or included in a set for each stage of the STA (see "Settings").

[0147] 传输资格 [0147] Transfer qualifications

[0148] 如以上所讨论的,AP 504可例如在参考信号700 (图7A)中或者在传输调度期间指示有资格进行传送的STA列表。 [0148] As discussed above, AP 504 may, for example in the reference signal 700 (FIG. 7A), or during transmission scheduling indication and transfer the STA eligible list. STA 506A - 506E可在由STA 506A - 506E发往AP 504的任何数据分组的QoS控制字段中指示它们有数据要传送。 STA 506A - 506E may by STA 506A - 506E indicating that they control any data sent to the AP 504 packet QoS field has data to be transmitted. 在一实施例中,STA 506A - 506E可向AP 504传送可包括QoS控制字段的QoS空元数据帧,以指示STA 506A - 506E具有缓冲单元以供传输。 In one embodiment, STA 506A - 506E may be transmitted to the AP 504 may include a QoS control field of the QoS empty frame metadata to indicate STA 506A - 506E with a buffer unit for transmission. 在一些实施例中,STA 506A- 506E可使用常规争用规程在任何数据帧中传送QoS控制字段。 In some embodiments, STA 506A- 506E QoS control field can be transmitted in any frame using conventional contention procedures. AP 504可接收QoS控制字段,确定哪些STA 506A - 506E有数据要传送,并且确定要指示哪些STA 506A - 506E有传输资格。 AP 504 can receive QoS control field to determine which STA 506A - 506E has data to transmit, and it is determined to indicate which STA 506A - 506E transport have qualified.

[0149] 在一些实施例中,STA 506A- 506E可通过根据802.1lah编码功率节省轮询(PS-Poll)帧中的上行链路数据指示来指示它们有数据要传送。 [0149] In some embodiments, STA 506A- 506E can save poll (PS-Poll) frame indicating data based on the uplink code power 802.1lah indicate that they have data to transmit. 在一些实施例中,STA506A - 506E可通过经由常规CSMA争用传送另一帧来指示它们有数据要传送。 In some embodiments, STA506A - 506E can be via conventional CSMA contention to indicate that they have transmitted data to be transmitted with another frame. 在一些实施例中,AP 504可指示期间STA 506A - 506E应当传送它们具有缓冲单元的指示的窗口。 During some embodiments, AP 504 may indicate STA 506A - 506E should be transferred to their windows indicating a buffer unit. 在一些实施例中,该时间窗口可在信标中通告并且实质上与RAW相似。 In some embodiments, the time window can be advertised in the beacon and is substantially similar to RAW. 该通告可例如通过使用如由IEEE 802.1lah标准定义的RPS信息元素来达成,其具有以下改变:RAW的类型被指示以仅用于UL指示。 This notification may, for example, such as by using a standard defined by the IEEE 802.1lah RPS information elements to achieve that with the following changes: type RAW is indicated only for the UL to instructions. AP还可关于每个个体STA调度TWT以允许STA发送UL指示。 AP also for each individual to allow STA STA scheduling TWT send UL instructions.

[0153] 在一实施例中,信道可被预分配、由STA 506A - 506E选择、和/或由AP506A - 506E选择并经由信道分配消息802、804、806和/或808来显式地发消息通知。 [0153] In one embodiment, the channel may be pre-assigned by the STA 506A - 506E selection, and / or by the AP506A - 506E via select distribution channels and messages 802,804, 806 and / or 808 to explicitly Message Notice. 信道分配消息802、804、806和/或808可在每个STA的传输之前的任何时间发送。 Channel assignment message 802,804, 806 and / or 808 may be sent at any time before the transmission of each STA. 在另一实施例中,AP 504可在紧挨在数据传输510、512、514和/或518之前发送的参考信号CTX601 - 604 (图6A - 6F)或MAC帧802、804、806和/或808中包括信道分配。 In another embodiment, AP 504 in the immediately 510,512,514 data transmission and / or reference signal 518 CTX601 before send - 604 (FIG. 6A - 6F) or MAC frames 802,804, 806 and / or 808 including channel assignment. 信道分配可通过MAC地址、AID、部分或散列AID、以及对应信道标识符中的一者或多者指示。 Channel assignment by MAC address, AID, part or hash AID, and the corresponding channel identifier in one or more of those instructions.

[0154] 在另一实施例中,可定义包括多个STA的群,每个STA可被指派群中的位置,并且该群可通过群ID或通过多播MAC地址来标识。 [0154] In another embodiment, the STA can be defined comprising a plurality of groups, each STA may be assigned a position in the group, and the group may or via multicast MAC address identified by the group ID. 因此,被分配给STA的信道可通过群ID或多播MAC地址来标识,并且进一步通过STA在由群ID标识的群中的位置来标识。 Thus, the STA is assigned to the channel can be identified by the group ID or multicast MAC address, and further by STA in the group by the group ID identifies the location identified. 用于设置群定义的消息可在UL-FDMA数据传输510、512、514和/或518之前的任何时间发送并且可被管理帧携带。 Message is used to set the group as defined in UL-FDMA can send data at any time 510,512,514 and / or 518 and can be managed before carrying frame. 用于指示关于某一数据传输的信道分配的消息可通过在数据传输510、512、514和/或518之前发送的管理或控制帧(例如,这些帧可以不基于上述SIFS或PIFS传送)传达,或者可在紧挨数据传输510、512、514和/或518之前的同步或MAC帧上发送。 For indicating a message about a data transmission channel assigned by the data transfer 510,512,514 and / or 518 before sending in the management or control frame (for example, the frame may not be transmitted based on the SIFS or PIFS) convey, or may be sent on the next synchronization or data transfer 510,512,514 MAC frames and / or 518 before. 在信道分配被包括在参考消息CTX 601 - 604或CF-Poll帧中的实施例中,接收机地址可包括对应于群并且由此标识用于STA的信道的多播MAC地址。 In the channel assignment message is included in the reference CTX 601 - 604 or embodiment of CF-Poll frame, the receiver may include the address corresponding to the group and thereby identify channels for STA's multicast MAC address.

[0155] 在信道被预分配的实施例中,并且当STA数目高于阈值且来自各STA的话务请求相似时,则可使用随机静态分配(例如,每个STA被半静态地分配到一信道)。 [0155] In an embodiment channels are pre-allocated, and when the number is higher than the threshold and the STA STA from each of the traffic request similar, may be allocated using a random static (e.g., each STA is a semi-statically assigned to channel). AP 504可向STA 506A - 506E指示哪个站被分配到哪个信道(例如,经由信道分配消息802、804、806和/或808)。 AP 504 may apply to the STA 506A - 506E indicating which station is assigned to which channel (for example, via the channel assignment message 802,804, 806 and / or 808). 如果信道由STA 506A - 506E选择,则STA 506A - 506E可选择由相应STA506A- 506E优选的信道并在该信道上等待。 If the channel by the STA 506A - 506E selected, the STA 506A - 506E select and wait on the channel from the corresponding STA506A- 506E preferred channel. STA 506A - 506E可显式或隐式地(例如,经由任何传输)通知AP 504它们在相应信道上的存在。 STA 506A - 506E may be explicitly or implicitly (for example, via any transmission) AP 504 notice their presence in the respective channel.

[0156] 在分配被显式地发消息通知的实施例中,信道分配消息802、804、806和/或808可在每个信道上发送或者仅在主信道上发送。 [0156] In the allocation message is explicitly notified embodiment, the channel assignment message 802,804, 806 and / or 808 can be transmitted in each channel or transmit only the main channel. 在STA 506A - 506E隐式地通知AP 504它们的存在的情况下,AP 504可基于由STA 506A- 506E传送的用于常规操作的任何数据、控制和/或管理帧的接收而知晓STA 506A- 506E位置。 In STA 506A - 506E under the AP 504 implicitly notify their presence, AP 504 may be based on any data for routine use by the STA 506A- 506E transmission, control and / or management frames received and alerted STA 506A- 506E location. 换言之,数据、控制和/或管理帧可以没有必要被设计用于信道指示。 In other words, data, control and / or management frames may not need to be designed for the channel indication. 在STA 506A- 506E能够在多个信道上接收帧的实施例中,在特定信道上寻址到STA的参考信号的接收可隐式地指示该特定信道被分配给所寻址的STA。 In STA 506A- 506E can receive frames on multiple channels embodiments, in particular channel reference signal addressed to the STA reception implicitly indicate the particular channel is assigned to the addressed STA. 具体而言,AP 504可在多个信道上传送多个参考帧CTX,每个参考帧CTX寻址到不同STA,由此定义信道分配。 Specifically, AP 504 may transmit a plurality of reference frames in CTX plurality of channels, each addressed to a different reference frame CTX STA, thereby defining a channel allocation.

[0160] 在一实施例中,可对分组的历时施加限制。 [0160] In one embodiment, the restrictions may be applied to the packet duration. 在一些实施例中,由STA 506A- 506E作出的传输具有不同长度。 In some embodiments, the transmission from the STA 506A- 506E made of different lengths. 在其它实施例中,由STA 506A- 506E作出的传输具有相同长度。 In other embodiments, the transmission made by the STA 506A- 506E have the same length.

[0161] 在UL通信510、512、514和/或518之后,AP 504可用块确收(BA)响应,由此确认DL通信被接收到。 [0161] After the UL communication at 510,512,514, and / or 518, AP 504 available block acknowledgment (BA) in response, thereby acknowledging a DL communication is received. AP 504可以按照自己意志用BA响应或者可被STA 506A - 506E提示(例如,经由块确收请求(BAR))。 AP 504 BA can respond according to their own will or may be STA 506A - 506E prompt (for example, via block acknowledgment request (BAR)). 如果STA 506A - 506E均能够在任何信道上进行接收,或者均能够在至少相同共用信道(诸如,主信道)上进行接收,则AP 504可广播单个块确收(BBA)。 If STA 506A - 506E are able to receive on any channel, or are able to receive at least the same shared channel (such as the main channel), the AP 504 can broadcast a single block acknowledgment (BBA). BBA帧携带用于多个STA(可能地在UL中发送了数据的所有STA)的块确收指示。 BBA frame for carrying a plurality of STA (STA may send all the data in the UL) acknowledgment indication block. 关于BBA帧的附加信息可在2009年12月8日提交的美国临时申请N0.61/267,734中找到,其通过引用纳入于此,并且在题为“METHOD AND APPARATUS FOR MULTICAST BLOCKACKNOWLEDGEMENT (用于多播块确收的方法和装置)”的申请中找到,其附加于此。 Additional information about BBA frame may provisional application in the United States December 8, 2009 filed N0.61 / 267,734 found, which is incorporated by reference herein, and entitled "METHOD AND APPARATUS FOR MULTICAST BLOCKACKNOWLEDGEMENT (for application multicast block acknowledgment method and apparatus of) "found in its attached hereto.

[0162] 在一实施例中,BBA可在主信道上发送。 [0162] In one embodiment, BBA can be transmitted in the main channel. 在各种实施例中,AP 504和/或STA506A- 506E可以旧式或高效率物理协议数据单元(PTOU)格式传送BA、BAR、和/或BBA。 In various embodiments, AP 504 can efficiently legacy or physical protocol data unit (PTOU) transfer BA, BAR, and / or BBA and / or STA506A- 506E format. 在AP 504和/或STA 506A - 506E在高效率PPDU格式中传送BA、BAR、和/或BBA的一些实施例中,带宽可小于20MHz。 In the AP 504 and / or STA 506A - 506E transmit some embodiments BA, BAR, and / or at high efficiency BBA PPDU format, the bandwidth may be less than 20MHz. 此外,不同BA、BAR、和/或BBA可具有不同历时,其可取决于用于传输的带宽。 In addition, different BA, BAR, and / or BBA may have different duration, which depends on the bandwidth available for transmission. 本文所包括的时序图以及它们示出的各种消息不是按比例决定的。 Timing diagram included herein as well as their various messages shown not to scale decisions.

[0163] 图9A - 9C示出了其中可采用本公开的各方面的附加时序图。 [0163] FIG. 9A - 9C shows a case where the present disclosure can be attached various aspects of the timing chart. 具体而言,图9A - 9C解说了如本文所描述的BA、BAR和BBA的使用。 Specifically, FIG. 9A - 9C illustrates a use such as BA, BAR and BBA herein described. 在一实施例中,传输51、512、514和518不同时结束,AP 504在UL通信完成之后立即用BA响应。 In one embodiment, the transmission 51,512,514 and 518 does not end at the same time, AP 504 after the UL communication is completed immediately respond to an embodiment of the BA. AP 504于是在接收到BAR之后用BA对剩余传输作出响应。 AP 504 So after receiving the BAR on the remaining transmission respond with BA. STA 506A- 506E可在其上传送了UL通信的信道、主信道、高效率主信道(例如,被定义以供高效率设备使用的主信道)、和/或任何其它信道上传送BAR。 STA 506A- 506E can be transmitted on the UL communication channel, the main channel, high efficiency of the main channel (for example, is defined for the primary channel high-efficiency equipment used), and / or any other channels transmitted BAR.

[0164] 例如,如图9A所解说的,AP 504可在UL通信514完成之后用BA 904A作出响应。 [0164] For example, as shown in the explanation 9A, AP 504 may be performed after the completion of a UL communication 514 responds with BA 904A. 在BA 904A已被STA 506C接收到之后,STA 506C可在信道522上向AP 504传送BAR 902B,信道522是DL通信512被STA 506B接收的信道。 After BA 904A STA 506C has been received, STA 506C BAR 902B can be transferred to the AP 504 in the channel 522, channel 522 is DL 512 is a communication channel to receive STA 506B. 一旦AP 504接收到BAR 902B,AP 504就用BA 904B响应。 Once the AP 504 receives the BAR 902B, AP 504 will use BA 904B response. BAR和BA循环,随后关于剩余STA (例如,STA 506A和STA 506E)继续。 BAR and BA cycle, then on the remaining STA (for example, STA 506A and STA 506E) to continue. AP 504可指令STA 506A - 506E设置对由STA 506A - 506E传送的数据的确收策略,以使得不多于一个STA 506A- 506E请求即时BA。 AP 504 can instruct STA 506A - 506E set by the STA 506A - 506E of data transfer strategy is indeed close, so no more than one STA 506A- 506E request immediate BA. 在一些实施例中,所有BA策略可被设为BA (不要求即时响应),但AP还是可选择一个或多个STA并向它们发送即时BA。 In some embodiments, the policy may be set to all BA BA (does not require an immediate response), but also select one or more AP STA to send them instant BA. AP 504在接收到即时确收请求或BAR之后可在数据被接收到的相同信道上和/或在主信道上传送确收或BA。 AP 504 after receiving the request or BAR immediate acknowledgment may be received in the same data channel and / or in the main channel transmission acknowledgment or BA. 附加BAR可由STA 506A - 506E在主信道和/或一个或多个副信道(诸如,数据被传送的相同信道)上发送。 Additional BAR by STA 506A - 506E send in the main channel and / or one or more subchannels (such as, data of the same channel is transmitted) on. 在此情形中,AP 504可在BAR被接收到的相同信道上和/或在主信道上传送确收或BA。 In this case, AP 504 can be received in the BAR on the same channel and / or acknowledgment or in the main channel transmission BA.

[0165] 在一实施例中,如果通信510、512、514和518在相同时间或接近相同的时间结束和/或在STA 506A- 506E仅可在受限子信道上进行接收的情况下,AP 504可在UL通信完成之后在每个子信道上用BA作出响应(例如,传输的结束是对AP 504发送BA的触发)。 [0165] In one embodiment, if the communication 510,512,514 and 518 at the same time or close to the same time ends and / or in the case of STA 506A- 506E can be carried out only on a limited sub-received, AP UL 504 may be performed after communication is completed on each subchannel respond with BA (for example, the end of the transmission is to transmit AP 504 triggers the BA). BA可在与UL通信被接收的信道相同的信道上传送。 BA can be transferred to the UL communication channel is received on the same channel. 例如,如图9B所解说的,AP 504可在UL通信510、512、514和518完成之后立即用BA 904A - 904D作出响应。 For example, as shown in the explanation 9B, AP 504 may be performed after the completion of a UL communication 510,512,514 and 518 immediately BA 904A - respond 904D. BA 904A - 904D可并发地传送。 BA 904A - 904D can transmit concurrently.

[0166] 在其中所有STA 506A - 506E均能够解码任何信道、或主信道526上的分组的实施例中,AP 504可在UL通信510、512、514和518完成之后广播BBA。 [0166] in which all STA 506A - 506E are able to decode any channel, or examples of grouping the main channel on the 526, AP 504 may broadcast BBA after UL communication 510,512,514 and 518 completed. 例如,如图9C所解说的,AP 504响应于UL通信510、512、514和518的终止完成而在主信道526上传送BBA 904E。 For example, as illustrated in FIG. 9C, AP 504 in response to transmit on the primary channel of communication 510,512,514 and 526 in UL 518 complete termination of BBA 904E. 由于所有STA 506A - 506E均能解码BBA 904E,因此仅一个BBA被传送。 Since all STA 506A - 506E could decode BBA 904E, thus only a BBA is transmitted. 在STA 506A - 506E之一为旧式STA的情况下,AP 504可指令高效率STA具有比旧式STA的传输短的传输。 In STA 506A - 506E of the old one under the circumstances STA, AP 504 can command high efficiency legacy STA STA has a short transmission ratio of the transmission. 来自旧式STA的传输的历时可从RTX帧中设置的历时字段推断出。 Took the field last transmission from the legacy STA may be provided from RTX frame inferred. 此外,AP 504可指令高效率STA使用无ACK策略。 In addition, AP 504 can command high efficiency STA uses no ACK policy.

[0167]使用情形 [0167] usage

[0168] 在一实施例中,本文关于图5A-9C描述的UL FDM协议在若干应用中实现。 [0168] In one embodiment, the article with respect to Figure 5A-9C UL FDM protocol implementations described in a number of applications. 例如,BSA可包括旧式STA和高效率STA。 For example, BSA may include a high efficiency and a legacy STA STA. UL FDM协议可通过将一些STA指派给通信介质中未另行使用的带宽的一部分来使用该未另行使用的带宽。 UL FDM agreement by some STA assigned to a part of the communication medium, not otherwise used bandwidth to the bandwidth not otherwise in use. 这可允许旧式STA和/或高效率STA并发地通信。 This may allow legacy STA and / or high efficiency STA communicate concurrently. 这在无线网络的BSS范围被限于高速率用户的情况下可以是有益的。 This is limited to the case of high rate users in range of a wireless network BSS can be beneficial.

[0169] 作为另一示例,如果PHY层使用频调交织办法,则可达成频率分集。 [0169] As another example, if the PHY layer uses tone interleaving approach, you can achieve frequency diversity. 使用频率分集,创建了要求最小干扰协调的跳频系统。 Using frequency diversity, created requiring minimal interference coordination of frequency hopping systems. 频调可被划分成两个或更多个子集。 Tone may be divided into two or more subsets. 第一STA可经由第一子集中的频调传送和/或接收数据,并且第二STA可经由第二子集中的频调传送和/或接收数据。 The first STA via a first subset of tones to transmit and / or receive data, and the second STA via the second subset of tones to transmit and / or receive data. 只要第一子集和第二子集不交叠,就可避免干扰。 As long as the first subset and the second subset of non-overlapping, interference can be avoided.

[0180] 图10示出了可在图5的无线通信系统500内采用的示例性无线通信方法的流程图1000。 [0180] FIG. 10 illustrates a flowchart of an exemplary wireless communication method in a wireless communication system 500 of FIG. 5 used in 1000. 该方法可全部或部分地由本文所描述的设备(诸如图4中所示的无线设备402)来实现。 The apparatus may be all or part of the method described herein by the (as shown in Figure 4 the wireless device 402) to achieve. 尽管所解说的方法在本文中是参照以上关于图1所讨论的无线通信系统100、以上关于图2-3和5A所讨论的无线通信系统200、250、300和500、以及以上关于图4所讨论的无线设备402来描述的,但本领域普通技术人员将领会,所解说的方法可由本文所描述的另一设备、或者任何其他合适的设备来实现。 Although the method is illustrated with reference to the above radio communication system on a wireless communication system discussed in Figure 1100, above with respect to FIG. 2-3 and 5A are discussed in this article 200,250,300 and 500, as well as above with respect to FIG. 4 the wireless device 402 to describe the discussion, but one of ordinary skill in the art will appreciate that the illustrated method may be another device as described herein, or any other suitable device to achieve. 尽管所解说的方法在本文是参照特定次序来描述的,但在各种实施例中,本文的各框可按不同次序执行、或被省略,并且可添加附加框。 Although the method illustrated herein is described with reference to a particular order, but in various embodiments, each box of this article can be executed in a different order, or omitted, and may add additional frames.

[0181] 首先,在框1010,接入点确定与该接入点相关联的无线设备集中每一个无线设备的性能特性。 [0181] First, at block 1010, the access point determines the access point with a wireless device on the performance characteristics associated with each wireless device. 例如,AP 504可确定BSA 502中每一个STA 506A - 506E的一个或多个性能特性。 For example, AP 504 may determine each of the STA 506A BSA 502 - 506E, one or more performance characteristics. 在各种实施例中,该性能特性可包括物理和/或RF特性,诸如举例而言,信号对干扰加噪声比(SINR)、RF几何学、收到信号强度指示符(RSSI)、调制和编码方案(MCS)值、干扰电平、信号电平,传输能力等等。 In various embodiments, the performance characteristics may include physical and / or RF characteristics, such as for example, signal to interference plus noise ratio (an SINR), RF geometry, the received signal strength indicator (the RSSI), and modulation coding scheme (MCS) value, interference level, signal level, transmission capacity and so on.

[0182] 随后,在框1020,接入点基于该性能特性将该无线设备集中的每一个无线设备分类到至少第一无线设备子集和第二无线设备子集中。 [0182] Subsequently, at block 1020, the access points based on the performance characteristics of the wireless device set for each category of wireless devices to at least a first subset of the wireless device and the second wireless device subset. 第一无线设备集可具有比第二无线设备集高的性能特性。 The first set of wireless devices may have a wireless device than the second set of high-performance characteristics. 例如,AP 504可将BSA 502中的每一个STA 506A - 506E分类到第一子集和第二子集中。 For example, AP 504 may be a BSA 502 each STA 506A - 506E sorted into a first subset and a second subset. 在一实施例中,第一无线设备子集可包括蜂窝小区内设备,并且第二无线设备子集可包括蜂窝小区边缘设备。 In one embodiment, the first wireless device may include a subset of cells within a cellular device, the wireless device and the second subset may include a cell edge devices. 例如,AP 504可将STA 506A - 506C分类为蜂窝小区内设备,因为它们物理靠近且可具有强信号强度。 For example, AP 504 may STA 506A - 506C classified within a cell devices because they are physically close and may have a stronger signal strength. 相反,AP 504可将STA 506D - 506E分类为蜂窝小区边缘设备,因为它们远离且可具有较低SINR。 Instead, AP 504 may STA 506D - 506E classified as cell edge devices, because they are away and may have a lower SINR.

[0183] 在各种实施例中,第一无线设备子集与第二无线设备子集相比可具有较高的信号对干扰加噪声比(SINR)、较高的几何学等级、较高的收到信号强度指示符(RSSI)、或者较大的传输能力。 [0183] In various embodiments, the first wireless device with a subset of the second subset of the wireless device can have a higher signal-to-interference plus noise ratio (an SINR), a high level geometry, higher compared to a received signal strength indicator (RSSI), or a greater transmission capacity. 在一个实施例中,第一无线设备子集可具有比第二无线设备子集高的调制和编码方案(MCS)值。 In one embodiment, a first subset of the wireless device may have a higher than a second subset of the wireless device modulation and coding scheme (MCS) values. 在一个实施例中,第一无线设备子集可具有比第二无线设备子集低的干扰。 In one embodiment, a first subset of the wireless device may have less than a second subset of the wireless device interference.

[0184] 在一些实施例中,接入点可将第二无线频率集指派给第二无线设备子集。 [0184] In some embodiments, the wireless access point may be a second set of frequencies assigned to the second wireless device subset. 例如,AP504可将信道526指派给STA 506E。 For example, AP504 channel 526 may be assigned to the STA 506E. AP 504可例如基于观察到的干扰等与其它设备相协调地指派信道。 AP 504 may, for example based on the observation of interference in coordination with other equipment assigned channel.

[0185] 在一些实施例中,接入点可从第二无线设备子集中的至少一个设备接收第二无线频率集的指示。 [0185] In some embodiments, the second access point from the wireless device at least a subset of the pointing device to receive the second set of radio frequencies. 例如,STA 506E可以例如基于观察到的干扰来作出其自己的信道指派。 For example, STA 506E may for example be based on the observed interference make its own channel assignment. STA506E可向AP 504传送该信道指派。 STA506E can transmit the channel assignment to the AP 504.

[0186] 在一些实施例中,接入点可将第二无线频率集的指示传送给不与该接入点相关联的一个或多个设备。 [0186] In some embodiments, the access point may indicate that the second set of radio frequency is transmitted to one or more devices and are not associated with the access point. 例如,参照图2B,AP 254A可作出一个或多个信道指派,并且可向例如AP 254C和/或STA 256G指示相关联的蜂窝小区边缘设备的信道指派。 For example, channel assignment Referring to FIG. 2B, AP 254A may be made of one or more channel assignment, and ask, for example AP 254C and / or STA 256G indicating cell edge device associated. 在一些实施例中,接入点可从不与该接入点相关联的一个或多个设备接收第二无线频率集的指示。 In some embodiments, one or more devices access point may never be associated with the access point indicates a second radio frequency receiver set. 例如,STA256G可取而代之地作出一个或多个信道指派并且可通知AP 254A和/或STA 256A。 For example, STA256G may instead be made to one or more channel assignment and may inform the AP 254A and / or STA 256A.
