[0082] 用于多信道操作的示例性RTS和CTS [0082] for multichannel operation of an exemplary RTS and CTS

[0083] IEEE802.1lac是对IEEE802.11标准的修正版,其使得能够在802.11网络中实现较高的吞吐量。 [0083] IEEE802.1lac is a modified version of IEEE802.11 standard, which makes it possible to achieve higher throughput in 802.11 networks. 通过诸如使用MU-MMO (多用户多输入多输出)和80MHz或160MHz信道带宽之类的几种手段来实现较高的吞吐量。 For example, by using the MU-MMO (multi-user multiple input multiple output) several means and 80MHz or 160MHz channel bandwidth class to achieve higher throughput. 802.1lac还称为甚高吞吐量(VHT)。 802.1lac also known as Very High Throughput (VHT).

[0084] 在802.1lac网络中,基本信道单元大约为20MHz宽。 [0084] In 802.1lac network, the basic channel unit is approximately 20MHz wide. 每个PPDU(物理层转换协议(PLCP)协议数据单元)可以跨越20、40、80、或160MHz (即,I个、2个、4个、或8个20MHz信道)。 Each PPDU (PHY protocol converter (PLCP) Protocol Data Unit) across 20,40,80, or 160MHz (i.e., I, 2, 4, or 8 channels 20MHz). 将用于发送数据的多个信道中的主信道分配给每个发射实体。 The primary channel will be used to transmit data to a plurality of channels allocated to each transmitting entity. 传输过程包括在主信道上执行实载波监听(real carrier sensing)和虚拟载波监听以及在其它信道上执行实载波监听,以确定多个可以使用的信道。 Transmission process including the implementation of a real carrier sense (real carrier sensing), and virtual carrier sense in the main channel and execute a solid carrier sense in other channels to determine a plurality of channels can be used.

[0085] 然而,由于较宽的PPDU带宽和隐藏节点的较高可能性,因而在确定PPDU的带宽之前需要确定接收机周围的自由(即,可用)信道。 [0085] However, due to the high bandwidth and the possibility of a wide PPDU hidden nodes, thus determining PPDU is determined before the receiver bandwidth around the free (i.e., available) channel. 产生的PPDU将跨越发射实体周围的“自由”带宽和接收实体周围的自由带宽中的较小者。 Resulting PPDU transmitting entity will span around "free" bandwidth and receiving entities around the free bandwidth is less.

[0086] 因此,需要用于有效地确定接收机周围的自由带宽的技术和装置。 [0086] Thus, the need for effective means to determine the technical and freedom around the receiver bandwidth. 此外,这种带宽确定应优选地允许:设置针对其它STA的网络分配向量(NAV)计数器,保留无线介质,并保护传输免遭隐藏节点的影响。 In addition, this bandwidth determination should preferably be allowed: settings for other STA's network allocation vector (NAV) counter, reservations wireless media, and to protect the transmission from the impact of hidden nodes.

[0087] 图6示出了根据本公开内容的某些方面,用于带宽发现的单一RTS/CTS帧交换600的例子。 [0087] FIG. 6 shows a certain aspect of the present disclosure, for example, the bandwidth found in a single RTS / CTS frame exchange 600. 对于根据IEEE802.1lac修正版的80MHz传输,可以在4个20MHz信道(CH1-CH4)上,从用于发送数据的发射实体(例如,AP110)发送诸如请求发送(RTS)帧602之类的短控制帧。 According IEEE802.1lac for revision of 80MHz transmission, in four 20MHz channel (CH1-CH4) on, from the transmitting entity for transmitting data (for example, AP110) to send a short frame 602 and the like, such as a request to send (RTS) control frames. 在复制模式下,将在主信道(例如,CHl)上发送的RTS帧602可以被拷贝,并如示出地在通过主信道发送的RTS帧的同时通过其它信道(例如,CH2-CH4)发送。 In copy mode, the RTS frame 602 transmitted on can be copied from the main channel (for example, CHl), and as shown in the same time RTS sent through the main channel of the frame transmitted through other channels (for example, CH2-CH4) .

[0088] 接收实体(例如,用户终端120)可以确定在其上发送了RTS帧的信道以及被确定为在接收实体周围可用的信道。 [0088] The receiving entity (for example, user terminal 120) can determine on which to send the channel RTS frame and is determined to be at the receiving entity around the channels available. 然后,响应于接收的RTS帧602,接收实体可以在可用信道(例如,CH1-CH2)上发送诸如允许发送(CTS)帧604之类的短控制帧。 Then, in response to the received RTS frame 602, the receiving entity may (e.g., CH1-CH2), such as a short control frame allows the transmission (CTS) frame 604 or the like on the available transmission channels.

[0089] 发射实体可以确定在其上发送了CTS帧604的信道。 [0089] The transmitting entity may determine on which to send the CTS frame 604 channels. 发射实体可以随后在可用信道(在其上发送了CTS帧604的信道)上发送数据606。 The transmitting entity can then available channel (on which to send the CTS frame 604 channels) to send the data 606. 如图6中所示,根据IEEE802.1lac修正版,将用于发送数据的带宽可以是40MHz (B卩,两个20MHz信道)。 As shown in Figure 6, according to IEEE802.1lac revision, the bandwidth for transmitting data can be 40MHz (B Jie, two 20MHz channels).

[0090] 概括而言,本公开内容的各个方面主要解决如何在发射机和接收机之间交换可用带宽(BW)信息。 [0090] In summary, the various aspects of the present disclosure mainly to solve how to exchange the available bandwidth (BW) between the transmitter and receiver of information. 可以隐式地(通过确定在其中确实发送RTS/CTS帧的信道)或显式地执行这种带宽信息的交换。 Implicitly (by determining the channel actually sent RTS / CTS frame in which) or explicitly perform the exchange of this information bandwidth. 可以通过将信息隐藏在传统(根据IEEE802.lla/b/g修正版已有的)帧格式(本文中指传统RTS帧)中,或者通过定义携带带宽信息字段的新的帧格式(本文中指VHTRTS帧),来完成显式的带宽信息交换。 The information can be hidden in the traditional (according IEEE802.lla / b / g revision of existing) frame format (herein refers to the traditional RTS frame), or by defining the bandwidth information field carries new frame format (herein refers to VHTRTS frame ), to complete the explicit bandwidth information exchange.

[0091] 本公开内容的某些方面还解决如何发送RTS/CTS帧以便提供对于发射机和接收机的保护。 Certain aspects [0091] The present disclosure also addresses how to send RTS / CTS frame in order to provide protection for the transmitter and receiver. 如本文所描述地,保护通常是指:RTS/CTS机制将无线介质保留足够长的时间间隔,以发送数据帧并接收相关联的确认(ACK)帧。 As described herein, the protection usually means: RTS / CTS mechanism will be retained long enough for the wireless medium time interval, to transmit data frames and receiving acknowledgment associated (ACK) frames.

[0092] 某些方面可以使用传统前导码和传统帧格式来执行RTS/CTS交换。 [0092] Certain aspects of the preamble using conventional and traditional frame format to perform the RTS / CTS exchange. RTS/CTS帧可以携带NAV信息以涵盖数据传输。 RTS / CTS frame may carry information NAV to cover data transmission. 这可以免受传统STA和VHT STA的影响。 This can be from the influence of traditional and VHT STA of STA. 这些方面可以采用隐式或显式的带宽信令机制。 These aspects may be implicit or explicit bandwidth signaling mechanism.

[0093] 某些其它方面可以使用传统前导码或VHT前导码和包含BW信息的VHT帧格式来执行RTS/CTS交换。 [0093] Certain other aspects of using conventional preamble or VHT VHT preamble and frame format BW contain information to perform RTS / CTS exchange. RTS/CTS帧可以携带NAV信息以涵盖数据传输。 RTS / CTS frame may carry information NAV to cover data transmission. 这可以免受传统STA和VHT STA的影响。 This can be from the influence of traditional and VHT STA of STA. 然而,由于事实上VHT RTS帧可能不会像传统RTS帧一样触发相同的行为,因而可能给传统STA造成不利。 However, due to the fact VHT RTS frame may not be the same as the traditional RTS frame trigger the same behavior, which may adversely to the traditional STA.

[0094] 某些其它方面使用传统前导码或VHT前导码和VHT帧格式来执行RTS/CTS交换,其中VHT帧格式包括显式的BW信息。 [0094] Other aspects of the use of certain conventional preamble or VHT VHT preamble and frame format to perform the RTS / CTS exchange, which VHT frame format includes explicit BW information. 可以对RTS/CTSNAV进行设置以仅涵盖RTS/CTS交换。 May RTS / CTSNAV be to only cover the RTS / CTS exchange settings. 可以在这种初始的RTS/CTS交换之后进行后续的使用传统前导码和传统帧格式的RTS/CTS交换。 Possible after such initial RTS / CTS exchange for subsequent conventional preamble and traditional frame format RTS / CTS exchange. 这些传统RTS/CTS帧可以携带NAV信息以涵盖数据传输。 These conventional RTS / CTS frame may carry information NAV to cover data transmission. 这很可能可以免受传统STA和VHT STA的影响。 This is likely to be free from the influence of traditional and VHT STA of STA.

[0095] 某些其它方面可以使用传统前导码和传统帧格式执行初始的RTS/CTS交换,在初始的RTS/CTS交换之后进行后续的使用传统前导码或VHT前导码和具有显式的BW信息的VHT帧格式的RTS/CTS帧交换。 [0095] Certain aspects may use other conventional preamble and the conventional frame format to perform the initial RTS / CTS exchange, after the initial RTS / CTS exchange subsequent conventional VHT preamble or a preamble having explicit information BW The RTS frame format VHT / CTS frame exchange.

[0096] 图7示出了用于根据在其中确实发送控制帧的信道,隐式地交换带宽信息的示例性操作700。 [0096] FIG. 7 shows a transmission control based on a frame which is really a channel bandwidth information exchange implicitly exemplary operation 700. 操作700可以由诸如APllO之类的发射实体执行。 Operation 700 may be performed by transmitting entity such APllO like. 在702处,操作700可以开始于在期望用于向装置(例如,接收实体)发送数据的一个或多个信道中的每个信道上向该装置发送第一控制帧。 In 702, the operation 700 may begin at desired for the device (e.g., the receiving entity) transmits data or a plurality of channels each channel to the means for transmitting a first control frame. 在704处,可以在所述信道中的至少一部分信道中的每个信道上接收第二控制帧,其中,所述信道中的所述部分信道中的信道在所述装置处是可用的。 In 704, a second control frame may be received at least a portion of each channel of the channels of the channel, wherein the channel portion of the channel of the channel at the apparatus are available. 在706处,发射实体可以使用所述信道中的所述至少一部分信道发送数据。 In 706, the transmitting entity may use at least a portion of the channel data transmission channel.

[0097] 图8示出了用于根据在其中确实发送控制帧的信道,隐式地交换带宽信息的示例性操作800。 [0097] FIG. 8 shows a transmission control based on a frame which is really a channel bandwidth information exchange implicitly exemplary operation 800. 操作800可以由诸如用户终端120之类的接收实体执行。 Operation 800 may be performed by the receiving entity the user terminal 120 and the like, such as. 在802处,操作800可以开始于在装置(例如,接收实体)处在期望用于向该装置发送数据的一个或多个信道中的每个信道上接收第一控制帧。 In 802, the operation 800 may begin at the device (e.g., the receiving entity) desired for each channel in one or more channels to the first receiving means for transmitting data control frame. 在804处,响应于接收第一控制帧,接收实体可以在所述信道中的至少一部分信道中的每个信道上发送第二控制帧,其中,所述信道的所述部分信道中的信道在所述装置处是可用的。 In 804, in response to receiving a first control frame, the receiving entity may send the second control channel frame at least a portion of each of the channels of the channel, wherein the channel portion of the channel in the channel The device is available at. 在806处,接收实体可以接收使用所述信道中的所述至少一部分信道发送的数据。 At least the data channel transmitted at 806, the receiving entity may receive the channel using a part.

[0098]方法 I [0098] The method I

[0099] 第一种方法联合地解决本公开内容的两个方面:(I)在其中发送RTS/CTS帧的信道隐式地代表BW信息,以及(2)定义保护级别。 [0099] The first method jointly solve two aspects of this disclosure: (I) in which the channel transmission RTS / CTS frame implicitly represent BW information, and (2) the definition of the level of protection. 该方法可以包括利用使用复制模式或拷贝模式发送的RTS帧和CTS帧。 The method may include the use of copy mode or using the RTS frame and the CTS frame transmitted copy mode. 换句话说,在主(20MHz )信道上发送的RTS PPDU被拷贝到发射机想要供传输使用的其它20MHz信道中的全部或一部分中。 In other words, the main RTS PPDU (20MHz) is transmitted on the channel you want to copy to the transmitter for transmission to use all or part of the other channels in 20MHz.

[0100] 可以通过使用根据IEEE802.1la修正版的前导码和帧格式来发送RTS帧(还称为传统RTS帧)。 [0100] RTS frames can be transmitted through the use of a modified version according to IEEE802.1la preamble and frame format (also known as a traditional RTS frame). 应注意的是,这种RTS帧不携带任何对发送的带宽的显式的指示。 It should be noted that this RTS frame carries no explicit indication of the bandwidth sent. 而是该方法依赖接收机在用于发送RTS帧(RTS帧的拷贝)的信道上进行检测的能力。 But this method relies on the receiver for sending RTS frame (RTS copy frame) will be the ability to detect channel.

[0101] 该方法中的步骤可以包括: [0101] The method may include the steps of:

[0102] 步骤1:发射实体(例如,表示为“TxSTA”的发射站)可以在于TxSTA处被被监听为自由的信道上使用复制模式发送一个或多个RTS帧。 [0102] Step 1: transmitting entity (for example, expressed as "TxSTA" transmitting stations) may be characterized at TxSTA been listening to a free channel using the copy mode to send one or more RTS frames. 这些自由信道可以代表期望用于发射数据的信道(即,期望的信道)。 These free channels can be used to transmit data representing the desired channel (ie, the desired channel). 自由信道的定义可以包括让载波监听指示在传输开始前无线介质在PIFS (点协调功能(PCF, point coordination function)巾贞间间隔)时间内是空闲的。 Definition of free channel may include instructions to make carrier sense before the beginning of the transmission of wireless media PIFS (Point Coordination Function (PCF, point coordination function) towel Zhen interval) time is idle. 例如,如图6中所示,可以在CH1-CH4上发送RTS帧602。 For example, as shown in Figure 6, may be sent on CH1-CH4 RTS frame 602.

[0103] 步骤2:接收实体(例如,表示为“RxSTA”的接收站河以接收RTS巾贞,并使用诸如多信道短训练字段(STF)检测之类的任何各种适当的技术确定在其上发送了RTS帧的信道。应注意的是,虽然这种检测不使用显式的信令,但是其依赖于物理(PHY)层处的信号检测能力。用“CH_RTS”表示的信道在接收机处被确定为在其上接收了RTS帧的信道。 [0103] Step 2: The receiving entity (for example, expressed as "RxSTA" receiving station to receive RTS towel Zhen river, and use as a multi-channel short training field (STF) to detect any of a variety of appropriate technologies and the like to determine in their the transmission of the channel RTS frame. It should be noted that, although this can not be detected using explicit signaling, but it depends on the physical (PHY) layer signal detection capability at The channel with "CH_RTS" represented at the receiver It is determined to be received at the channel RTS frames thereon.

[0104] 步骤3:RxSTA可以在被确定为在RxSTA周围是自由的一组CH_RTS上向TxSTA发送一个或多个CTS帧。 [0104] Step 3: RxSTA can be determined to be around RxSTA is a group of freedom CH_RTS CTS transmitting one or more frames to TxSTA. 例如,如图6中所示,可以在CH1-CH2上发送CTS帧604。 For example, as shown in Figure 6, may be sent on CH1-CH2 CTS frame 604.

[0105] 步骤4 =TxSTA可以接收由RxSTA发送的CTS帧,并且可以确定在其上发送了CTS帧的信道。 [0105] Step 4 = TxSTA can receive CTS frame transmitted by the RxSTA, and may determine the transmit channel on which the CTS frame. 然后,TxSTA可以在于其上发送了CTS帧的信道上(例如,如图6中示出的CH1-CH2)发送数据。 Then, TxSTA thereon can be transmitted in the channel of the CTS frame (e.g., FIG. 6 shows the CH1-CH2) to send data. 应注意的是,虽然对在其上接收了CTS帧的信道进行的确定不使用显式的信令,但其依赖于PHY层处的信号检测能力。 It should be noted that, although the determination of the channel received the CTS frame on which the non-use of explicit signaling, but it depends on the signal detection capability at the PHY layer.

[0106] 图9示出了用于通过控制帧显式地交换带宽信息的示例性操作900。 [0106] Figure 9 shows an explicit bandwidth information exchange through the operation of a control frame 900 for example. 操作900可以由诸如APllO之类的发射实体执行。 Operation 900 may be performed by a transmitting entity such APllO like. 在902处,操作900可以开始于向装置(例如,接收实体)发送第一控制帧,该第一控制帧指示用于向所述装置发送数据的期望带宽。 In 902, the operation 900 may begin transmitting the first frame to the control means (e.g., the receiving entity), the first control frame indicating a desired bandwidth is used to transmit data to the device. 在904处,发射实体可以接收第二控制帧,该第二控制帧指示所述装置的可用带宽。 In 904, the transmitting entity may receive the second control frame, the second control frame indicating the available bandwidth of the device. 在906处,发射实体可以基于所述可用带宽和所述期望带宽中的较小者发送数据。 In 906, the transmitting entity may transmit data bandwidth based on the lesser of the available bandwidth and desired.

[0107] 图10示出了用于通过控制帧显式地交换带宽信息的示例性操作1000。 [0107] FIG. 10 shows a switching bandwidth explicitly by a control frame of information for an exemplary operation 1000. 该操作可以由诸如用户终端120之类的接收实体执行。 This operation may be performed by the receiving entity the user terminal 120 and the like, such as. 在1002处,操作1000可以开始于在装置(例如,接收实体)处接收第一控制帧,该第一控制帧指示用于向该装置发送数据的期望带宽。 In 1002, operations 1000 may begin at the device (e.g., the receiving entity) to receive a first control frame, the first frame indicates the control means for transmitting data to the desired bandwidth. 在1004处,响应于接收第一控制帧,所述装置可以发送第二控制帧,该第二控制帧指示到所述装置的可用带宽。 In 1004, in response to receiving a first control frame, the control means may transmit a second frame, the second control frame indicates to the available bandwidth of the device. 在1006处,所述装置可以接收使用所述可用带宽和所述期望带宽中的较小者发送的数据。 In 1006, the receiving device may use the available bandwidth and the bandwidth of the smaller of the desired data transmission.

[0108]方法 2 [0108] Method 2

[0109] 第二种方法仅解决BW信息交换。 [0109] The second method can only solve BW information exchange. 方法2与方法I的不同之处在于发送的带宽信息包括在使用传统帧分组前导码或VHT帧分组前导码发送的RTS/CTS帧中。 Method 2 and Method I, except that the bandwidth information is included in the transmitted frame packet using conventional VHT preamble or a preamble transmitted frame packet RTS / CTS frame. 用方法2解决的主要问题是:确保包括带宽信息的RTS/CTS帧仍然作为对于传统设备的有效的RTS/CTS帧。 The main problem is solved by the method 2: Be sure to include bandwidth information of RTS / CTS frame is still as valid for traditional equipment RTS / CTS frames. 在下面针对方法2描述了用于实现此目的的几种技术。 In the following two methods are described for several techniques for achieving this purpose.

[0110] 使用RTS/CTS帧中的持续时间字段(版本I) [0110] The RTS / CTS frame duration field (Version I)

[0111] 第一种技术的思想是使用MAC头部402中的持续时间字段408中的比特(诸如两个或更多个最低有效位(LSB))作为带宽指示符。 [0111] Thought first technique is to use MAC header 402 Duration field 408 bits (such as two or more of the least significant bit (LSB)) as an indicator of bandwidth. 在这种方式下,带宽指示可以“隐藏”在传统RTS帧或传统CTS帧中。 In this manner, the bandwidth indication can be "hidden" in the traditional or conventional RTS frame the CTS frame. 两个比特足以指示20、40、80、160MHz带宽的使用。 Two bits is sufficient to indicate the use of 20,40,80,160MHz bandwidth. 应注意的是,持续时间字段408以微秒(μ s)来指示时间。 It should be noted that the duration field 408 microseconds (μ s) to indicate the time. 对于某些方面,持续时间字段408中的至少一个最高有效位(MSB)可以指示持续时间字段包括带宽信息。 For certain aspects, the duration of the at least one field in the most significant bit 408 (MSB) comprises a Duration field may indicate bandwidth information.

[0112] 步骤1:发射实体可以基于将发送的数据来计算传输时间T,定义Tl=4*ceil (T/4),定义T_RTS=T1+ (指示BW的LSB),并将发送的RTS帧中的持续时间字段设为T_RTS。 [0112] Step 1: The transmitting entity may transmit data based on the calculated transmission time T, the definition of Tl = 4 * ceil (T / 4), defines T_RTS = T1 + (BW indicates the LSB), RTS frame and transmitted The duration of the field to T_RTS.

[0113] 步骤2:支持VHT的STA (其是RTS帧的期望接收者)可以基于Tl来确定期望的保留结束时间,Tl是通过首先将LSB设置为O而根据(RTS的持续时间字段408的)T_RTS来获得的。 [0113] Step 2: The support VHT STA (which is the intended recipient of the RTS frame) can be determined based on the desired retention Tl end time, Tl is set by first LSB under O (RTS duration field 408 ) T_RTS be obtained. 传统STA (或者不是RTS帧的期望接收者的VHT STA)可以简单地将保留的时间设置为T_RTS。 Traditional STA (or not the intended recipient of the RTS frame VHT STA) may simply be set to retention time T_RTS.

[0114] 步骤3:支持VHT的RxSTA可以如下计算针对CTS的持续时间字段(定义ST_CTS):T_CTS=T1+ (指示RxSTA 处的可用BW 的LSB)。 [0114] Step 3: The RxSTA support VHT can be calculated as follows for the CTS duration field (defined ST_CTS): T_CTS = T1 + (instructions available at BW's LSB RxSTA).

[0115] 步骤4:TxSTA可以从RxSTA接收CTS巾贞,并使用持续时间字段中的LSB以确定将使用的可用带宽。 [0115] Step 4: TxSTA can receive CTS towel Zhen from RxSTA, and duration of use LSB field to determine the available bandwidth to be used.

[0116] 使用RTS/CTS帧中的持续时间字段(版本2) [0116] The RTS / CTS frame duration field (Version 2)

[0117] 第二种技术可以使用与版本I相同的方案,并具有下面所描述的某些修改。 [0117] The second technique I can use the same version of the program, and with some modifications described below. 应注意的是,CTS帧可能稍微延长由RTS设置的NAV。 It should be noted, CTS frame may be slightly longer NAV set by RTS. 为了避免此问题,可以将持续时间字段“预先”增加4μ s以构建足够的裕度。 To avoid this problem, you can be the duration of the field "in advance" to increase 4μ s to build a sufficient margin.

[0118] 步骤1:发射实体可以基于将发送的数据来计算传输时间Τ,定义TI =4* (1+ceil (T/4)),定义T_RTS=T1+ (指示BW的LSB),并且将要发送的RTS中的持续时间字段408设置为T_RTS。 [0118] Step 1: The transmitting entity may be based on data sent to calculate the transmission time Τ, define TI = 4 * (1 + ceil (T / 4)), is defined T_RTS = T1 + (indicative of BW LSB), and to be transmitted The RTS in the duration field 408 is set to T_RTS.

[0119] 步骤2:与版本I的步骤2相同。 [0119] Step 2: The same as the version I of step 2.

[0120] 步骤3:支持VHT的RxSTA可以根据T_CTS=T1_ (指示RxSTA处的可用BW的LSB)来计算针对CTS帧的持续时间字段(定义为T_CTS)。 [0120] Step 3: The support of RxSTA VHT can T_CTS = T1_ (indicating RxSTA available at BW's LSB) to calculate the duration field for the CTS frame (defined as T_CTS).

[0121] 步骤4:与版本I的步骤4相同。 [0121] Step 4: Step I is the same as version 4.

[0122] 使用L-SIG字段 [0122] The L-SIG field

[0123] 对于某些方面,RTS/CTS帧可以包括传统前导码。 [0123] For certain aspects, RTS / CTS frame may include conventional preamble. 这种传统前导码可以具有传统信号(L-SIG)字段510,并且可以将L-SIG字段中的一个比特用以指示RTS/CTS帧是否包括带宽信息。 Such conventional can having a conventional preamble signal (L-SIG) field 510, and may be L-SIG field one bit to indicate RTS / CTS frame bandwidth information is included. 对于某些方面,L-SIG字段的同相(I)分量或正交(Q)分量中的至少之一可以指示RTS或CTS帧是否包括带宽信息。 For certain aspects, at least one component of the in-phase L-SIG field (I) component or the quadrature (Q) may indicate whether the RTS or CTS frame including bandwidth information.

[0124] 对L-SIG字段的使用可以与方法2中公开的其它技术结合。 Other techniques [0124] use of the L-SIG field may be the method disclosed in combination. 例如,持续时间字段408中的两个LSB可以在传统RTS/CTS帧中指示带宽信息,而L-SIG字段中的一个比特可以指示持续时间字段包括带宽信息。 For example, the duration field 408 may indicate that the two LSB bandwidth information in a conventional RTS / CTS frame, and the L-SIG field may indicate the duration of one bit field includes bandwidth information.

[0125]使用服务字段比特 [0125] Using the service field bits

[0126] 对于某些方面,服务字段比特可以用作带宽指示。 [0126] For certain aspects, the service field bits can be used as your bandwidth. 当被用于加扰器初始化时,服务字段可以包括数据字段(数据部分526)中的第一部分(例如,前16个比特)。 When used in a scrambler initialization field may include service data fields (data portion 526) in a first portion (e.g., the first 16 bits). 作为一种选择,(根据IEEE802.1la修正版)9个保留的服务比特中的任意2个比特可以用于指示带宽。 As an alternative, (according IEEE802.1la amended) 9 bits reserved service any two bits may be used to indicate the bandwidth. 对于某些方面,还可以包括用于奇偶校验的一个附加比特。 For certain aspects, it may also include an additional bit for parity.

[0127] 作为第二种选择,加扰器初始化种子可以用于指示带宽。 [0127] As a second option, scrambler initialization seed may be used to indicate the bandwidth. 对于使用该第二种选择的某些方面,可以针对每个带宽来定义加扰器种子。 For some aspects of the second choice, you may be defined scrambler seed for each bandwidth. 例如,可以针对20、40、80和160MHz定义总共4个加扰器种子。 For example, you can define a total of four scrambler seed for 20,40,80 and 160MHz. 对于其它方面,每个基本服务集(BSS)的TxSTA可以针对每个带宽定义加扰器中要使用的比特。 For other aspects, each Basic Service Set (BSS) of TxSTA can be defined for each of the bandwidth to be used in the scrambler bit.

[0128] 传统接收机STA将不会受到影响。 [0128] conventional receiver STA will not be affected. 支持VHT的STA (其接收到RTS)可以检测RTS的发射机地址。 Supports VHT's STA (which received RTS) RTS transmitters can be detected address. 如果RTS是由VHT STA发送的,那么接收机STA可以使用加扰器字段中的信息来确定BW。 If RTS is transmitted by the VHT STA, the receiver STA can use the scrambler field information to determine BW. 如果RTS是由传统STA发送的,那么接收机STA可以认为没有发送BW信 If RTS is transmitted by traditional STA, then the receiver STA that it did not send the letter BW

肩、O Shoulder, O

[0129] 使用帧控制比特 [0129] The frame control bits

[0130] 对于某些方面,RTS/CTS帧中的MAC头部402中的帧控制字段410中的比特可以用作带宽指示。 [0130] For certain aspects, RTS / CTS frame MAC header 402 frame control field 410 bits can be used as your bandwidth. 当前有7个“无用的”比特,全部设置为O。 There are currently seven "useless" bits, all set to O. 对于某些方面,帧控制比特中的一个可以用于指示RTS/CTS帧是新类型的具有带宽信息的RTS/CTS帧,并且两个或更多个其它比特可以用于指示带宽信息。 For certain aspects, the frame control bits may be used to indicate an RTS / CTS frame is a new type of bandwidth information of the RTS / CTS frames, and two or more other bits can be used to indicate the bandwidth information.

[0131] 俥用NAV比特 [0131] Che with NAV bits

[0132] 对于某些方面,NAV中的两个或更多个比特(例如,2个LSB)可以用作带宽指示。 [0132] For certain aspects, NAV two or more bits (e.g., 2 LSB) can be used as the bandwidth indication. 接收到RTS帧的VHT STA可以被通告RTS帧是由VHT STA发送的。 RTS frames received VHT STA can be advertised RTS frame is transmitted by the VHT STA. 可以使用发送方的地址来提供这种通告,发送方的地址可以指示STA的类型(即,传统STA与VHT STA)。 You can use the address of the sender to provide such notice, the address of the sender STA may indicate the type (ie, traditional STA and VHT STA).

[0133] 除了上面描述的技术外,还可以使用其它技术以用于交换包括在RTS/CTS帧中的带宽信息。 [0133] In addition to the techniques described above, you can also use other techniques for the exchange of information, including bandwidth RTS / CTS frame. 对于某些方面,可以重用物理层(PHY)传统前导码中的比特来指示带宽信息。 For certain aspects, you can reuse the physical layer (PHY) conventional preamble bits indicate the bandwidth information. 然而,这可能对传统STA造成不利影响。 However, this may adversely affect the traditional STA.

[0134]方法 3 [0134] Method 3

[0135] 第三种方法包括使用更新的802.1lac前导码。 [0135] A third method involves the use of updated 802.1lac preamble. 该方法联合地解决了BW信息交换和帧交换以用于保留介质。 This method solves the BW joint exchange of information and frame exchange for retention medium.

[0136] 步骤I =TxSTA可以使用针对RTS PPDU中的数据部分的复制模式来发送具有VHT(802.1lac)前导码的RTS帧。 [0136] Step I = TxSTA can be used to transmit the data for RTS PPDU part of the copy mode RTS frame has VHT (802.1lac) preamble. 为了以信号发送操作的复制模式,可以对VHT-SIG-A字段512中的当前保留比特中的一个保留比特进行重新标记以表示复制模式。 In order to replicate the pattern signal transmission operation can be retained in a bit reserved bits to mark for VHT-SIG-A field 512 to indicate the current copy mode. 该复制模式比特可以被设置为“1”,并且信道带宽比特可以表示在其上发送RTS帧的带宽。 The copy mode bit can be set to "1", and the channel bandwidth bits may represent the transmission bandwidth RTS frame on it.

[0137] 步骤2 =RxSTA可以接收RTS帧,并且通过使用RTS帧中的复制模式比特和信道带宽指示符的组合来确定在其上发送了RTS的信道。 [0137] Step 2 = RxSTA can receive the RTS frame, and by using a combination of RTS frame copy mode bits and channel bandwidth indicator to determine on which to send the RTS channel. CH_RTS可以表示的信道在接收机处被确定为在其上接收RTS帧的信道。 CH_RTS channel can be represented at the receiver is determined to be received RTS frame on which channel. [0138] 步骤3:RxSTA可以在被确定为在RxSTA周围是自由的一组CH_RTS上向TxSTA发送CTS帧。 [0138] Step 3: RxSTA can be determined as RxSTA sending CTS frame around the freedom to TxSTA a group CH_RTS. 如果使用一个以上的20MHz信道,则可以对VHT-SIG-A复制模式比特进行设置,并且信道带宽比特可以指示在其上发送CTS的带宽。 If you use more than one 20MHz channel, you can VHT-SIG-A copy mode bit is set, and the channel bandwidth bits may indicate CTS bandwidth to send it on.

[0139] 步骤4:TxSTA可以接收由RxSTA发送的CTS帧。 [0139] Step 4: TxSTA can receive CTS frame transmitted by the RxSTA. TxSTA可以(使用来自VHT-SIG-A的信息)确定在其上发送了CTS的信道,并且在于其上发送了CTS的信道上发送数据。 TxSTA can (using information from VHT-SIG-A) is determined on which to send the CTS channels, and sent on its channel to send data CTS.

[0140]方法 4 [0140] Method 4

[0141] 第四种方法仅解决BW信息交换。 [0141] The fourth method can only solve BW information exchange. 在方法4中,可以定义RTS帧的新格式(称为VHT-RTS)。 In Method 4, you can define a new RTS frame format (called VHT-RTS). 应注意的是,这涉及帧格式而不是PHY前导码。 It should be noted that this relates to a PHY frame format instead of the preamble. 前导码可以是传统前导码或VHT前导码。 Preamble may be a conventional VHT preamble or a preamble. 虽然当发送具有传统前导码的信号时,传统STA很可能能够解码信号,但对它们来说,VHT-RTS帧将不像RTS帧一样。 Although when the signal having the conventional preamble transmission, the conventional STA is likely to be able to decode the signal, but for them, VHT-RTS frame will not as RTS frame. 传统STA将只根据持续时间字段408设置网络分配向量(NAV)。 Traditional STA will only allocation vector (NAV) based on the duration field 408 set up the network. VHT-RTS帧中的持续时间字段可以指示的NAV针对CTS帧的接收、短帧间间隔(SIFS)、以及数据的后续传输涵盖足够的时间。 NAV VHT-RTS frame Duration field may indicate the reception, a short interframe space (SIFS), and the subsequent transmission of the CTS frame data for a sufficient time to cover.

[0142] VHT-RTS帧格式可以包含具有BW的显式指示的新字段。 [0142] VHT-RTS frame format may comprise fields with the new BW explicit indication. 类似地,可以定义针对CTS的新的帧格式(称为VHT-CTS),新的帧格式包括指示BW的字段。 Similarly, we can define a new format for the CTS frame (called VHT-CTS), a new frame format includes a field indicating BW. 新的RTS/CTS帧可以是新的控制巾贞或者可以使用控制封装器(control wrapper)。 The new RTS / CTS frame may be a new control towel infidelity or can use the control wrapper (control wrapper).

[0143]方法 5 [0143] Method 5

[0144] 在该第五种方法中,RTS/CTS帧可以包括具有一定数量比特的高吞吐量控制(HTC)字段。 [0144] In the fifth method, RTS / CTS frame may comprise a number of bits having the high throughput control (HTC) field. 对于某些方面,HTC字段中的两个或更多个比特可以指示期望带宽。 For certain aspects, HTC field two or more bits may indicate the desired bandwidth.

[0145]方法 6 [0145] Method 6

[0146] 第六种方法解决帧交换以用于保护。 [0146] A sixth frame switching solution for protection. 在方法6中,可以交换包含显式的BW信息的VHT RTS/CTS帧,以发现可用BW。 6 In the process, may contain explicit BW exchange information VHT RTS / CTS frame, in order to discover the available BW. 由VHT RTS/CTS设置的NAV可以仅涵盖RTS/CTS交换,而不涵盖数据交换。 NAV set by VHT RTS / CTS can cover only RTS / CTS exchange, rather than covering the data exchange. 图11示出了根据方法6的用于带宽发现的双重RTS/CTS交换1100。 Figure 11 illustrates a method for dual RTS 6 according to the bandwidth found / CTS exchange 1100.

[0147] 首先,TxSTA可以在已知的自由信道(例如,图11中示出的CH1-CH4)上发送一个或多个具有传统复制式前导码或VHT前导码的VHT-RTS帧1102。 [0147] First, TxSTA can send one or more of the known free channels (for example, Figure 11 shows the CH1-CH4) VHT-RTS traditional replicated preamble or VHT preamble frame 1102. 其次,RxSTA可以在由VHT-RTS帧1102指示的信道当中的已知的自由信道(例如,图11中示出的CH1-CH2)上发送一个或多个具有传统复制式前导码或VHT前导码的VHT-CTS帧1104。 Secondly, RxSTA free channels can be known by the VHT-RTS frame 1102 indicating which channel (for example, Figure 11 shows the CH1-CH2) send a copy on or more of a traditional style preamble or VHT preamble The VHT-CTS frame 1104.

[0148] 在前面的交换之后,可以交换传统RTS/CTS帧。 [0148] After the preceding exchange, exchange conventional RTS / CTS frames. 换句话说,TxSTA可以在由使用拷贝模式的VHT-CTS帧1104指示的信道上以复制模式发送一个或多个具有传统前导码的传统RTS (L-RTS)帧1106。 In other words, TxSTA can be used by the copy mode VHT-CTS frame 1104 indicating the channel to transmit one or more conventional RTS (L-RTS) frame 1106 has a preamble in the conventional copying mode. 然后,RxSTA可以在由VHT-CTS帧1104之前所指示的自由信道上发送具有复制的传统前导码的传统CTS (L-CTS)帧1108。 Then, RxSTA may be sent by the free channel VHT-CTS frame indicated before 1104 have a copy of the traditional preamble traditional CTS (L-CTS) frame 1108. 在接收传统CTS帧1108之后,TxSTA可以在由VHT-CTS帧1104指示的信道上发送数据1110。 After receiving the traditional CTS frame 1108, TxSTA may be sent in 1104 by the VHT-CTS frame data 1110 indicates the channel.

[0149] 如上面所提到地,由VHT-RTS/CTS帧设置的NAV可以仅涵盖RTS/CTS交换,而不涵盖数据交换。 [0149] As mentioned above ground, NAV frame set by the VHT-RTS / CTS can cover only RTS / CTS exchange, rather than covering the data exchange. 例如,对于某些方面,VHT-RTS帧1102中的持续时间字段408可以指示的NAV针对VHT-CTS帧1104的接收、短帧间间隔(SIFS)、以及传统RTS帧1106的后续传输涵盖足够的时间。 For example, for some aspects, VHT-RTS frame 1102 in the NAV duration field 408 may indicate subsequent transmission frame 1106 for receiving VHT-CTS, a short interframe space (SIFS), as well as traditional RTS frame 1104 covered sufficiently time. 对于其它方面,VHT-RTS帧1102中的持续时间字段408可以指示的NAV针对VHT-CTS帧1104的接收、第一SIFSJ.S RTS帧1106的后续传输、第二SIFS、以及传统CTS帧1108的接收涵盖足够的时间。 For other aspects, NAV VHT-RTS frame in 1102 Duration field 408 may indicate for VHT-CTS frame received 1104, the first SIFSJ.S RTS frame subsequent transmission 1106, a second SIFS, as well as traditional CTS frame 1108 received covers enough time.

[0150] 相比而言,由传统RTS/CTS机制设置的NAV可以涵盖数据交换。 [0150] In contrast, NAV set by the traditional RTS / CTS mechanism can be covered by the data exchange. 例如,L-RTS帧1106中的持续时间字段408可以指示的NAV针对L-CTS帧1108的接收、短帧间间隔(SIFS)、以及数据1110的后续传输涵盖足够的时间。 For example, NAV L-RTS frame 1106 in the duration field 408 may indicate the L-CTS frame 1108 for receiving, a short interframe space (SIFS), and the subsequent transmission data 1110 covers enough time. 在这种方式下,由传统RTS帧和传统CTS帧设置的NAV保护数据的传输。 In this way, the transmission frame set by the traditional RTS frame and the CTS NAV traditional data protection.

[0151]方法 7 [0151] 7

[0152] 类似于上面描述的方法6,方法7也包括使用显式的带宽信息进行带宽发现的双重RTS/CTS交换。 [0152] The procedure similar to that described above 6, 7 also includes the use of explicit bandwidth information found double the bandwidth RTS / CTS exchange. 然而,方法7需要在交换VHT-RTS/CTS帧之前交换传统RTS/CTS帧。 However, the method 7 requires before exchanging VHT-RTS / CTS frame exchange traditional RTS / CTS frames.

[0153] 更具体地说,TxSTA可以在主信道上(或者在拷贝模式下在所有信道上)发送传统RTS帧。 [0153] More specifically, TxSTA in the main channel (or in copy mode in all channels) to send a traditional RTS frame. RxSTA可以在所有空闲的信道上接收传统RTS帧并发送传统CTS帧。 RxSTA traditional RTS frames can receive all free channels and transmit traditional CTS frame. 由于这些帧没有携带显式信息,因此BW确定可能不可用(除非按照上面针对方法I所描述地隐式地执行)。 Since these frames do not carry explicit information, so BW determined may be unavailable (unless it is the method I described above with respect to implicitly execute). 在先前的交换之后TxSTA可以在自由信道上使用拷贝模式发送具有VHT前导码或传统前导码的VHT-RTS帧。 TxSTA can send VHT VHT-RTS frame having a preamble or traditional preamble using the Copy mode after the previous channel in the free exchange. VHT-RTS帧可以指示在发射实体方处的自由信道。 VHT-RTS frame may indicate the free side of the channel at the transmitting entity. RxSTA可以在可用信道上使用拷贝模式发送具有传统前导码或VHT前导码的VHT-CTS帧。 RxSTA can send VHT-CTS frame traditional preamble or VHT preamble using copy mode available channels. VHT-CTS帧可以指示接收实体方处的自由信道。 VHT-CTS frame may indicate the entity receiving free channels at a party. 随后,TxSTA在由VHT-CTS帧指示的信道上发送数据。 Subsequently, TxSTA send data on the channel by the VHT-CTS frame indication.

[0154]方法 8 [0154] 8

[0155] 方法8可以包括通过传统RTS/CTS帧的扩展来显式地指示带宽信息。 [0155] The method may include by conventional RTS / CTS frame extended to explicitly indicate bandwidth information. 如图12中所示,VHT-RTS帧1200 (或VHT-CTS帧1250)可以包括传统RTS帧(或传统CTS帧)和额外附带的符号,该额外附带的符号称为VHT扩充字段(VAF)1210 (或1260)。 Shown in Figure 12, VHT-RTS frame 1200 (or VHT-CTS frame 1250) may include symbols traditional RTS frame (or traditional CTS frame) and additional incidental, the extra symbols are called VHT expansion incidental field (VAF) 1210 (or 1260). 由L-SIG字段1202(或1252)指示的持续时间可以仅涵盖RTS介质访问控制(MAC)协议数据单元(MPDU) 1204(或CTS MPDU1254),而不涵盖VAF。 The duration of the L-SIG field 1202 (or 1252) may indicate only covers RTS MAC (MAC) protocol data unit (MPDU) 1204 (or CTS MPDU1254), not covered by VAF.

[0156] 方法8可以允许传统节点解码RTS/CTS消息并设置NAV。 [0156] The method may allow traditional node decoding RTS / CTS messages and set the NAV. 然而,如果L-SIG长度字段指示RTS帧的长度(20个字节)或CTS帧的长度(14个字节),那么VHT STA可以准备解码一个额外的符号。 However, if the L-SIG field indicates the length of the RTS frame length (20 bytes) or the length of the CTS frame (14 bytes), the VHT STA can prepare an additional symbol decoding. VHT STA能够在SIFS (短帧间间隔)以内响应RTS,因此可以允许仅12 μ s 的预算用于VAF1210、1260。 VHT STA capable of responding to the RTS SIFS (short interframe space) or less, so you can allow only 12 μ s budget for VAF1210,1260.

[0157] 可以使用各种数据速率选择来发送VAF。 [0157] can be used to transmit a variety of data rate selection VAF. 对于某些方面,可以以最低速率发送VAF。 For certain aspects, at the lowest transmission rate VAF. 对于其它方面,可以以与前述的MPDU相同的数据速率发送VAF,这可以提供解码优势。 For other aspects, it may be the same as previously described MPDU data rate transmission VAF, which may provide advantages decoded. 对于某些方面,可以像RTS/CTS MPDU 一样在“复制”模式下发送VAF。 For certain aspects, it can be as RTS / CTS MPDU transmitted as VAF in "Copy" mode.

[0158] VAF1210、1260中的仅24个比特可以是有效的。 The [0158] VAF1210,1260 only 24 bits may be effective. VAF可以被设计成正好以6Mb/s装入一个符号。 VAF may be designed just to 6Mb / s mounted one symbol. 可以将其它比特设置为填充类型或固定的类型。 Other bits can be set to fill type or fixed type. 对于某些方面,VAF1210、1260可以包含至少一个8比特的循环冗余校验(CRC)和6个尾部比特。 For certain aspects, VAF1210,1260 may comprise at least an 8-bit cyclic redundancy check (CRC) and 6 tail bits. 8比特的CRC可以使得能够进行鲁棒的检测。 8-bit CRC can enables robust detection. 在24比特的VAF的情况下,10个信息比特可用于指示带宽。 In the case of a 24-bit VAF of 10 information bits can be used to indicate the bandwidth.

[0159] 对于某些方面,例如,即使没有检测到VHT-RTS帧1200的VAF,支持VHT的目的地STA仍可以在主信道上发送VHT-CTS帧1250。 [0159] For certain aspects, for example, even if not detected VHT-RTS frame 1200 VAF, supported destination VHT STA can still send in the main channel VHT-CTS frame 1250.

[0160]方法 9 [0160] 9

[0161] 第九种方法联合地解决了BW信息交换和帧交换以用于保护。 [0161] ninth method joint solution to the BW information exchange and frame exchange for protection. 方法9可以包括下列步骤: The method may include the steps of:

[0162] 步骤I =TxSTA可以仅在主信道(B卩,具有20MHz带宽)上不使用复制模式的前提下发送使用VHT前导码的VHT-RTS帧,并接收VHT-CTS帧。 [0162] Step I = TxSTA may not be used to send preamble using VHT VHT-RTS frame premise copy mode only in the main channel (B Jie, with 20MHz bandwidth) on, and receives VHT-CTS frame.

[0163] 步骤2 =TxSTA使用逐渐增加的带宽(例如,40MHz然后80MHz,相应地使用2个信道然后使用4个信道)发送VHT-RTS帧。 [0163] Step 2 = TxSTA increasing use of bandwidth (for example, 40MHz and 80MHz, respectively using two channels and then use the 4-channel) send VHT-RTS frame.

[0164] 步骤3:如果接收的响应于上面的步骤2的VHT-CTS帧指示与VHT-RTS帧相比较小的带宽,那么TxSTA可以停止发送VHT-RTS,并根据由所接收的VHT-CTS帧指示的带宽发送数据。 [0164] Step 3: if the received response to the above steps VHT-CTS frame indicating VHT-RTS frame as compared with less bandwidth, then TxSTA stop sending VHT-RTS, and based on the received VHT-CTS 2 of the bandwidth to send data frames indicated. 如果没有接收到响应于步骤2的VHT-CTS帧,那么TxSTA可以使用PIFS延续(PIFScontinuation)以在已知的可用信道上发送数据。 If no response is received at step VHT-CTS frame 2, then you can use the PIFS TxSTA continuation (PIFScontinuation) to the available channels in a known transmission data. 例如,如果没有接收到响应于步骤2中的针对较高带宽的VHT-RTS帧的VHT-CTS帧,那么TxSTA可以以目前为止接收的VHT-CTS帧的最高带宽发送数据。 For example, if no VHT-CTS frame is received in response to the step 2 for higher bandwidth VHT-RTS frame, then the maximum bandwidth of the transmission data may be far TxSTA received VHT-CTS frame.

[0165] 图13示出了用以根据方法9,使用逐渐增加的传输带宽,通过控制帧来交换带宽信息的示例性操作1300。 [0165] FIG. 13 illustrates a method according to 9, increasing the use of transmission bandwidth, the bandwidth to exchange information through a control frame exemplary operation 1300. 操作1300可以由发射实体(例如,接入点110)执行。 Operation 1300 may be performed by a transmitting entity (e.g., access point 110). 在1302处,操作1300可以开始于通过第一带宽向装置(例如,诸如用户终端120之类的接收实体)发送第一控制帧。 In 1302, operations 1300 may begin by transmitting a first bandwidth of a first control frame to the device (e.g., a user terminal such as a receiving entity 120 and the like). 在1304处,发射实体可以通过第一带宽接收第二控制帧。 In 1304, the transmitting entity may receive the second control frame via a first bandwidth. 在1306处,发射实体可以通过逐渐增加的传输带宽向所述装置重复第一控制帧的传输。 In 1306, the transmitting entity by increasing the bandwidth of the first control frame repeatedly transmitted to the device. 该传输可以被重复进行直到:(1)虽然没有接收到响应于在特定的带宽上发送的第一控制帧的第二控制帧,但在低于该特定的带宽的带宽上接收到了第二控制帧;或者(2)通过较低的带宽接收到响应于在特定的带宽上发送的第一控制帧的第二控制帧。 The transmission may be repeated until: (1) Although not receive a response to the second control frame of the first control frame transmitted on a particular bandwidth, but lower than the specific bandwidth to the bandwidth of receiving a second control frame; or (2) to the first control frame received in response to transmission on a particular bandwidth by a second control frame lower bandwidth. 在1308处,发射实体可以在所述较低的带宽上向所述装置发送数据。 In 1308, the transmitting entity may transmit data to the device on the lower bandwidth.

[0166] 对于发送显式的BW信息的某些方面,可以在RTS/CTS帧中的NAV或帧控制字段410中发送BW信息。 [0166] For certain aspects of sending explicit BW information in RTS / CTS frame or frame control field 410 NAV sent BW information. 接收实体可以在确定显式的BW信息之前检测RTS帧的发送地址对应于支持多信道的STA或其它实体(即,支持802.1lac,802.1laf、或后来的修正版的VHT设备)。 The receiving entity can detect RTS frame before determining explicit BW send address information corresponding to support multichannel STA or other entity (ie, support 802.1lac, 802.1laf, or later revision of VHT equipment). 对于某些方面,可以基于表查询来检测支持多信道的设备已发送了RTS/CTS巾贞。 For certain aspects, based on table queries to support multichannel detection device has sent RTS / CTS towel infidelity. 对于其它方面,可以基于所述地址属于由例如标准化团体分配的地址的集合(或范围内)来检测支持多信道的设备已发送了RTS/CTS帧。 For other aspects, for example, can be set by the standardization bodies belonging to the assigned address (or within range) to detect support multichannel device has sent RTS / CTS frame based on the address.

[0167] 如图14中所示,可以在RTS帧1400中提供显式的BW帧。 [0167] shown in Figure 14, you can provide explicit BW frame RTS frame 1400. 根据某些方面,RTS帧1400可以基于传统RTS,但具有一些差别。 According to certain aspects, RTS frame 1400 may be based on traditional RTS, but with some differences. 包括一个额外字节(I个8位字节)的字段1402可以包括在RTS帧中,并且位于FCS字段1404之前。 Includes an additional byte (I octets) field 1402 may be included in the RTS frame, and is located before the FCS field 1404. 额外字节字段1402可以包括例如2比特的BW指示(表示为“BW信息”)字段1406。 Additional byte field 1402 may include, for example 2 bits indicative of BW (represented as "BW information") field 1406. 字段1402中的其它比特可以是为将来的可选特性而保留的(表示为“RSVD”)。 The other bit field 1402 may be an optional feature for the future reserved (represented as "RSVD"). 根据某些方面,帧1400可以是通过使用如IEEE802.1lad修正版中的子类型扩展来定义的新的控制帧。 According to certain aspects, the frame 1400 can be controlled by using a new frame as IEEE802.1lad revision of subtype defined extensions. 作为一个例子,可以使用根据802.1lad的类型控制(01)和子类型控制帧扩展(0110)、扩展的子类型1011来定义控制帧。 As an example, you can use based on the type of control 802.1lad (01) and sub-type control frame extension (0110), subtype 1011 to expand the definition of control frames. 作为另一个例子,可以使用类型扩展(11)和子类型VHT-RTS (0001)来定义控制帧。 As another example, you can define a control frame using the type extension (11) and sub-type VHT-RTS (0001).

[0168] 如图15中所示,可以在CTS帧1500中提供显式的BW信息。 [0168] As shown in FIG. 15, the frame may be provided in the CTS 1500 BW explicit information. 根据某些方面,CTS帧1500可以基于传统CTS,但具有一些差别。 According to certain aspects, CTS frame 1500 may be based on conventional CTS, but with some differences. 包括一个额外字节(8个比特)的字段1502可以包括在CTS帧中,并且位于FCS字段1504之前。 It includes an additional byte (8 bits) may be included in the field of the CTS frame 1502, and 1504 is located before the FCS field. 额外字节字段1502可以包括例如2比特的BW指示(表示为“BW信息”)字段1506。 Additional byte field 1502 may include, for example 2 bits indicative of BW (represented as "BW information") field 1506. 字段1502中的其它比特可以是为将来的可选特性而保留的(表示为“RSVD”)。 The other bit field 1502 may be an optional feature for the future reserved (represented as "RSVD"). 根据某些方面,帧1500可以是通过使用如IEEE802.1lad修正版中的子类型扩展而定义的新的控制帧。 According to certain aspects, the frame 1500 can be a new control frame such as by using a modified version of IEEE802.1lad subtype defined extensions. 作为一个例子,可以使用根据802.1lad的类型控制(01)和子类型控制帧扩展(0110)、扩展的子类型1100来定义控制帧。 As an example, you can use based on the type of control 802.1lad (01) and sub-type control frame extension (0110), subtype 1100 to expand the definition of control frames. 作为另一个例子,可以使用类型扩展(11)和子类型VHT-CTS (0010)来定义控制帧。 As another example, you can define a control frame using the type extension (11) and sub-type VHT-CTS (0010).

[0169] 上面描述的方法和装置提供了用于使用RTS/CTS交换,通过信号的方式发送将用于无线通信的带宽的各种选择,其支持至少20MHz、40MHz、80MHz、160MHz或更高的带宽。 [0169] The method and apparatus described above provides a method for using the RTS / CTS exchange, transmitted by way of the signal will be used to select a variety of wireless communication bandwidth, which supports at least 20MHz, 40MHz, 80MHz, 160MHz or higher bandwidth. 除了这种带宽信息交换以外,本公开内容的各个方面还可以允许多个信道中的NAV保护。 In addition to this bandwidth information exchange, various aspects of the present disclosure may also allow NAV protect multiple channels.
