[0016] 对于无线网络性能的一个限制是因为在无线信道中的衰落引起的随机波动而导致的差可靠性和覆盖。 [0016] For a wireless network performance limitation is poor reliability and coverage because the random fluctuations due to fading in wireless channels caused. 在基于中继的蜂窝无线网络中的合作下行链路通信技术使得多个中继站和可能一基站共同地向多个用户发射信息,使在分布式结构中多入多出(MIMO)益处的提取成为可能,包括合作多样性、合作复用和分布式阵列(即功率效率)的增益。 In a relay-based cellular wireless network technology makes cooperation downlink communication may be a plurality of relay stations and base stations transmit common information to a plurality of users, so that in a distributed architecture multiple input multiple output (MIMO) benefits that extracts possible, including cooperative diversity, cooperative multiplexing and distributed arrays (ie, power efficiency) gain. 这使得合作中继通信成为蜂窝无线网络中用于吞吐量、覆盖和可靠性提高的理想技术。 This makes it ideal for cooperative relay communication technology for cellular wireless network throughput, coverage and improved reliability.

[0017] 在本领域中增加无线网络中的吞吐量、容量和覆盖改善将是一个进步,特别是对于位于或邻近扇区区域边界或小区边缘的用户而言,扇区区域边界或小区边缘是因为基础收发机站和/或中继站天线配置和定位形成的,并且从而遭受由于低信号干扰噪声比情况而引起的差性能。 [0017] increase the throughput in a wireless network in the art, capacity and coverage improvement would be an improvement, particularly for users located at or near the edge of a sector or cell boundary region in terms of a sector or cell edge is the boundary region Because base transceiver stations and / or relay station antenna configuration and positioning is formed, and thus suffer from poor performance due to low signal to interference noise ratio situations caused. 在下行链路模式中,这些小区边缘用户的性能改善可以通过使用合作传输技术来实现,由此多个中继站和可能的基站共同地相互作用以分享它们的天线,从而以合作多样性、合作复用和分布式阵列增益的形式提取MMO益处。 In the downlink mode, performance improvement of these cell edge users by using cooperative transmission techniques may be implemented, whereby multiple relay stations and possibly the base station interact jointly to share their antennas, thereby cooperation diversity, cooperative multiplexing used and distributed array gain benefits in the form of extracts MMO. 可选地,在下行链路和上行链路模式中均可采用分数频率复用,以通过减少由于在许多重叠通信信道中给定频率的重复使用而引起的小区边缘干扰来提供无线网络改进。 Alternatively, in the downlink and uplink mode fractional frequency reuse can be adopted in order to provide wireless network improved by reducing the cell edge due to interference in many overlapping communication channel at a given frequency reuse caused. 进一步地,可通过作为减少在无线网络中干扰的一种方法,仔细控制到小区边缘用户的传输的可能性使到小区边缘用户的传输随机化来提供无线网络改进。 Further, to provide wireless network improvements may be transmitted so that the cell-edge users as a way randomized by reducing interference in a wireless network, the possibility of carefully controlling the transmission of the cell edge users. 可以为改善无线网络性能提供基于中继的分数频率复用策略,它能支持在诸如基础收发机站和中继站这样的多个基础终端间使用概率干扰抑制技术的合作传输。 May provide for improved wireless network performance relay-based fractional frequency reuse policy that can support among a plurality of base terminals such as base transceiver station and the relay station cooperative transmissions using probabilistic interference mitigation techniques. 中继和接入链路可在频率上和时间上分离。 Relay and access links may be separated in time and in frequency. 从而,在无线网络中的用户可享受干扰抑制、合作多样性和功率效率的联合益处。 Thus, the user in a wireless network may enjoy the combined benefits of interference suppression, cooperative diversity and power efficiency.

[0018] 现在参考附图,在图1中描述了根据一些实施例的基于中继的分数频率复用小区100的示意图。 [0018] Referring now to the drawings, description of the relay-based fractional frequency according to a schematic view of some embodiments of the multiplexed cell 100 in Figure 1. 在一个实施例中,具有服务基站105的基于中继的分数频率复用小区100被六个中继站110、112、114、116、118和119围绕。 In one embodiment, having a relay-based fractional frequency reuse cell 100 is six relay stations 110,112,114,116,118 and 119 surrounding the serving base station 105. 在另一个实施例中,可使用三个中继站,然而总的来说,可在基于中继的分数频率复用小区100中任意位置放置任何数目的中继站。 In another embodiment, three relay stations may be used, but in general, can be placed in any number of relay stations relay-based fractional frequency reuse cell 100 in any position. 中继站发射和接收去往和来自服务基站105和/或去往其他中继站和/或去往移动站的信号,以改善到位于邻近基于中继的分数频率复用小区100边缘的区域中的移动站的通信质量。 The relay station to transmit and receive to and the serving base station 105 and / or destined for other relay stations and / or to the mobile station signals from, in order to improve the edge 100 is located adjacent the multiplexed relay-based fractional frequency cell area of the mobile station communication quality. 为了在中继站110、112、114、116、118和119处提供功率节省和最小化同信道干扰,中继站部署的一个考虑是使中继站覆盖区域不重叠。 In order to provide power savings and minimizing co-channel interference at the relay station 110,112,114,116,118 and 119, a relay station deployment is to be considered to make the relay station coverage areas do not overlap.

[0019] 取决于在小区100中的位置,给定移动站(MS)将与服务基站105或者一个或多个中继站110、112、114、116、118和119相关联。 [0019] depends on the position in the cell 100, a given mobile station (MS) to the serving base station 105 or one or more relay stations 110,112,114,116,118 and 119 are associated. 例如,在小区100中心的MS可能直接与服务基站105相连接,而在小区100边缘的MS可能与一个或多个中继站110、112、114、116、118和119相连接。 For example, in MS the cell centers 100 may be directly connected to the serving base station 105, 100 in the cell edge MS may be connected to one or more relay stations 110,112,114,116,118 and 119. 进一步地,取决于MS的位置,可在无线电接入链路上采用不同的频谱复用策略,其中无线电接入链路可以在服务基站105和MS之间或在中继站110、112、114、116、118和119和MS之间,包括⑴通过服务基站105和中继站110、112、114、116、118和119其中之一的频谱复用,(ii)通过多个中继站110、112、114、116、118和119的频谱复用,和(iii)通过服务基站105和多个中继站110、112、114、116、118和119的频谱复用。 Further, depending on the location of the MS, may employ different spectrum on the radio access link reuse strategy, wherein the radio access link may be between the serving base station 105 and MS or the relay station 110,112,114,116, between 119 and 118 and MS, including ⑴ multiplexing and spectrum through relay stations 110,112,114,116,118 and 119 of one of the serving base station 105, (ii) through a plurality of relay stations 110,112,114,116, 118 and 119 of spectrum reuse, and (iii) reuse by 105 and a plurality of relay stations 110,112,114,116,118 and 119 spectrum serving base station.

[0020] 多跳中继和频谱复用技术考虑到吞吐量、容量和覆盖改善,但是应当管理由于服务基站105和中继站110、112、114、116、118和119在无线接入链路上同时传输而引起的结果干扰,以避免由于严重干扰问题引起的性能损失。 [0020] Multi-hop relaying and spectrum multiplexing techniques taking into account the throughput, capacity and coverage improvement, but it should be managed because of the serving base station 105 and relay stations 110,112,114,116,118 and 119 on the radio access link at the same time result of the transmission caused by interference, to avoid performance losses due to severe interference problems caused. 在小区100边缘处的移动站可能遭受干扰问题。 In the mobile station 100 at an edge of the cell may suffer from interference problems. 类似地,位于中继站110、112、114、116、118和119覆盖区域边缘的用户也可能遭受类似的干扰问题,该干扰问题不仅是由来自其他小区(即小区100外的所有小区)的同信道干扰引起的,还是由在小区100内一即服务基站105和/或中继站110、112、114、116、118和119——的MS引起的小区内干扰。 Similarly, relay stations 110,112,114,116,118 and 119 located in the coverage area of the edge users may suffer from similar interference problems, not only the interference problem by co-channel from other cells (i.e. all cells 100 outside the cell) of interference caused by the cell or within the cell that is the serving base station 100 to 105 and / or a relay station MS 110,112,114,116,118 and 119-- caused interference. 为了解决该问题,关于小区100内给定的MS的复用因子(resue factor)不仅应当考虑它相对于服务基站105的地理位置,还应当考虑它相对于中继站110、112、114、116、118和119的位置来调整。 To solve this problem, on a given area within 100 MS reuse factor (resue factor) should not only consider its location relative to the serving base station 105, it should also be considered with respect to the relay station 110,112,114,116,118 119 and the position adjustment.

[0021] 在图1中,根据频道区域120、130、140、150、160和170分配基于中继的小区100上 [0021] In Fig. 1, according to the channel regions 120,130,140,150,160 and 170 are allocated based on cell relay 100

的频率复用和信道分配方案。 Frequency reuse and channel allocation scheme. 在分数频率复用小区100的中心处,服务基站105在由第二频道区域130围绕的第一频道120区域中操作。 In the fractional frequency reuse cell 100 at the center of the serving base station 105 operating in the second channel region 130 surrounded by a first channel 120 region. 在该实施例中,使用第二频道区域130的目的是与第一频道区域120相比降低频率复用,从而减少由在该区域中的移动站所经历的同信道干扰,使得移动站能够接收在吞吐量、容量和覆盖方面更好的服务质量。 In this embodiment, the purpose of using the second channel region 130 is compared with the first channel region 120 reduces the frequency reuse, thus reducing by the mobile station in this area experienced co-channel interference, so that the mobile station is able to receive Better quality in terms of throughput, capacity and coverage service. 在分数频率复用小区100中心处这种类型的频率复用通过在基于中继的分数频率复用小区100中心的具有变化复用度的两个信道之间分配资源,来向位于服务基站105附近的MS提供改善的通f目。 In the fractional frequency reuse cell 100 at the center of this type of frequency reuse by allocating resources among the multiplexed relay-based fractional frequency center of the cell 100 having two channels reusability of change, to the serving base station 105 is located MS nearby provide improved through f head.

[0022] 中继站110和116在由第四频道150区域围绕的第三频道140区域中的小区100边缘附近操作,以向MS提供增强的通信,否则该MS将经历严重同信道干扰。 [0022] The relay stations 110 and 116 operate near the cell 100 edge in a region surrounded by a fourth channel 150 of the third channel 140 region to provide enhanced communications to the MS, otherwise, the MS will experience severe co-channel interference. 在该实施例中,在由第五频道170区域围绕的第三频道140区域中操作的中继站112和118以及在由第六频道160围绕的第三频道140区域中操作的中继站114和119被类似地配置,以在小区100内提供分数频率复用(FFR)。 In this embodiment, the relay station 112 and relay stations 118 and 114 in the channel 160 by a sixth channel 140 around the third operating region by the fifth channel 170 in the region surrounding the third channel region 140 and 119 is similar to the operation of arranged to provide a fraction of the cell 100 within the frequency reuse (FFR). 中继站110、112、114、116、118和119可将相同的频道用于位于最接近每一个中继站的移动站,以最大化频率复用的频谱效率利益。 Relay stations 110,112,114,116,118 and 119 may be the same frequency channel for a mobile station located closest to each relay station to maximize spectral efficiency benefits of frequency reuse. 进一步地,每一个中继站还能够将不同的频道用于在它们各自覆盖区域边缘的移动站。 Furthermore, each relay station is also able to different channels in their respective coverage areas for the edges of the mobile station. 因此,与那些在频道区域140中的移动站相比,向频道区域150、160和170中的移动站提供较低的频率复用。 Thus, as compared with those in the mobile station 140 in the channel region, the channel region 150, 160 and 170 the mobile station to provide a lower frequency reuse. 在小区100的这些区域中降低频率复用减少了由移动站所经历的同信道干扰,从而增强了吞吐量、容量和覆盖。 Reducing the frequency reuse reduces experienced by the mobile station co-channel interference in these areas of the cells 100, thus increasing the throughput, capacity and coverage. 在另一方面,除了对位于中央信道区域周界线周围的信道区域应用的FFR外,还可以向与紧邻中继站的第三频道140相应的中央信道区域应用完全分数复用。 On the other hand, in addition to FFR located in the central region of the channel around the perimeter of the channel region of the application, you can also close the relay station to the third channel 140 corresponding to the channel region of the central application completely fraction reuse.

[0023] 在一些实施例中,频道区域150、160和170的一个或多个可对应于相同的频道,意味着对在中继站110、112、114、116、118和119覆盖区域边缘的用户的中继站110、112、114、116、118和119间更紧密的频率复用。 [0023] In some embodiments, one or more of the channel region 150, 160 and 170 may correspond to the same channel, the edge of the coverage area means that the relay station 110,112,114,116,118 and 119 of the user's 110,112,114,116,118 and 119 relay stations between tighter frequency reuse. 并且,在一些实施例中,频道区域120和140可对应于相同的频道,意味着对在高频率复用下服务的用户的服务基站105和中继站110、112、114、116、118和119间的更紧密的频率复用。 Also, in some embodiments, the channel region 120 and 140 may correspond to the same channel, means for the user in the high frequency reuse under service serving base station 105 and relay stations 110,112,114,116,118 and 119 The tighter frequency reuse. 最终,在一些实施例中,频道区域130、150、160和170中的一个或多个可对应于相同的频道,意味着对在较低频率复用下服务的用户的服务基站105和中继站110、112、114、116、118和119间的更紧密的频率复用。 Finally, in some embodiments, the channel regions 130,150,160 and 170 may correspond to one or more of the same channel, means for the user in a lower frequency reuse under the service of the serving base station 105 and relay station 110 more closely frequencies 112, 114 and 119 of reuse.

[0024] 在一些实施例中,位于小区100边缘的MS将在具有三个正交波段(或子信道集)的三个频率复用下被服务,以避免同信道干扰,这些正交波段被分配给中继站对,其中每一个中继站位于小区100相反侧,即如图1所示,则频道区域150、160和170将对应于三个分离的频带。 [0024] In some embodiments, a cell located at the edge of the MS 100 having three orthogonal bands (or subchannels) of the three frequency-multiplexed by the service, in order to avoid co-channel interference, these bands are orthogonal allocated to the relay station, wherein each relay station located on the opposite side of the cell 100, i.e., shown in Figure 1, the channel region 150, 160 and 170 corresponding to three separate frequency bands. 在可选实施例中,两个的复用模式可应用于向在可选模式中的三个中继站的每一个提供两个子信道。 In an alternative embodiment, the two multiplexing modes can be applied to each of the three alternative modes of relay stations to provide two sub-channels. 在另一个实施例中,六个的复用模式可用于为每一个中继站提供它自己的频道,需要一共六个正交信道分配。 In another embodiment, six multiplexing mode may be used for each relay station provides its own channel, requires a total of six orthogonal channel allocation.

[0025] 在图1所示的实施例中,位于紧邻服务基站105 (在第一频道120内)的MS在复用I策略下被服务,位于近邻中继站110、112、114、116、118和119其中之一(在第三频道140内)的小区100边缘用户在复用I策略下被服务。 [0025] In the embodiment shown in Figure 1, is located close to the serving base station 105 MS (in the first channel 120) in the alternate I policy is service in the neighboring relay stations 110,112,114,116,118 and 119 of which one (in the third channel 140) 100 users at cell edge I reuse strategy is service. 可选地,对远离服务基站105 (在第二频道区域130内)和任何中继站110和116 (在第四频道150区域内)、112和118 (在第五频道170区域内)以及114和119 (在第六频道160内)的MS应用复用3策略,以确保这些MS的因频谱复用而导致的干扰损失最小化。 Optionally, to stay away from the serving base station 105 (130 in the second channel region) and any relay stations 110 and 116 (150 in the fourth channel region), 112 and 118 (170 in the fifth channel region) as well as 114 and 119 MS (the sixth channel 160.) Application reuse 3 policy to ensure the spectral loss due to the interference caused by reuse of these MS minimized.

[0026] 图2是具有产生合作FFR小区200的合作分数频率复用的在图1中图示的基于中继的分数频率复用小区100的示意图。 [0026] Figure 2 is a relay-based fractional frequency reuse cell fraction cooperative FFR cell 200 cooperate frequency reuse a schematic 100 illustrated in FIG. 1 in the production. 出于在合作中继模式中实现成功的干扰管理以有益于在蜂窝系统中位于小区边缘或外围、通常经历差SINR条件的MS的目的,下行链路(DL)合作中继技术与基于中继的FFR概念相结合。 For successful interference management in a cooperative relay mode to benefit at the cell edge or periphery in a cellular system, generally experience poor SINR conditions MS purposes, a downlink (DL) relay-based cooperative relaying technique The FFR concepts combined. 产生的合作多样性和功率效率增益可导致小区边缘MS的显著性能增益;大致上可比得上由接收最大比合并(MRC)技术提供的增益。 Cooperative diversity and power efficiency gains can lead to generation of a significant performance gain of the cell-edge MS; substantially comparable provided by the receiver maximum ratio combining (MRC) technique gain.

[0027] 在存在如图2所示的基于中继的FFR策略的情况下,为小区边缘MS包括DL合作中继支持意味着,可由多个基础终端(服务基站105和/或中继站110、112、114、116、118和119)通过使用诸如分布式空时编码(STC)、分布式波束形成、合作复用等合作中继技术的它们的同时传输,来服务在复用3区中(即在第二频道区域130、第四频道150区域、第六频道160或第五频道170区域内)的MS。 [0027] In the case of relay-based FFR policy, including a cell-edge MS to support DL cooperative relaying means exist as shown in Fig. 2, by multiple infrastructure terminals (serving base station 105 and / or relay stations 110, 112 Their simultaneous transmission, 114, 116 and 119), such as through the use of distributed space-time coding (STC), distributed beamforming, cooperative and other cooperative relay multiplexing technology, to serve in the complex with three zones (ie In the second channel region 130, the fourth channel region 150, the sixth channel region) of MS 160 or fifth channel 170.

[0028] 在图2中,应用合作中继技术以向具有差的信号与干扰加噪声比(SINR)的目标节点220提供增强的干扰管理能力。 [0028] In Figure 2, application of cooperative relaying techniques to have a poor signal to interference plus noise ratio (SINR) of the target node 220 to provide enhanced interference management capabilities. 产生的合作多样性和功率效率增益导致目标节点220 (例如蜂窝电话、个人数字助手(PDA)、便携式PC、手持计算机设备等形式的移动站)在性能上的显著提高。 Cooperative diversity and power efficiency gains resulting causes the target node 220 (e.g., cellular phones, personal digital assistants (PDA), a portable PC, handheld computer device in the form of a mobile station) significantly improved in performance. 合作多样性由使用诸如分布式空时编码(STC)、分布式波束形成、合作复用等合作中继技术、提供同时或几乎同时传输的多个基础终端(中继站110、112、114、116、118和119,服务基站105等)产生。 Cooperation diversity such as distributed space-time coding (STC), distributed beamforming by using, cooperation and other cooperation relay multiplexing technology to provide simultaneous or nearly simultaneous transmission of multiple infrastructure terminals (relay station 110,112,114,116, 118 and 119, serving base station 105 and the like) produced.

[0029] 基于中继的FFR和DL合作多样性的结合使得目标节点220能够连同合作中继的功率效率优点一起同时实现FFR和合作多样性的干扰抑制优点,对于合作FFR小区200边缘移动站被称为合作FFR(C00p-FFR)。 [0029] Cooperative diversity combining based FFR and DL relay node 220 can make the target along with power efficiency advantages of cooperative relaying together while achieving interference suppression FFR and cooperative diversity advantage, for cooperative FFR cell 200 edge mobile station is called co-FFR (C00p-FFR). 在一个实施例中,目标节点220在第五频道170和第六频道160中和/或在第五频道170和第六频道160之间的coop-FFR区域210中使用下行链路(DL)模式中的合作多样性操作。 In one embodiment, the target node 220 in the fifth channel 170 and the sixth channel 160 and / or 170 in the fifth channel and the sixth channel 160 between coop-FFR region 210 using a downlink (DL) mode Cooperative diversity operation. 结果,目标节点220可从中继站118接收用于接收的分配的时频资源,同时将给邻近中继站119在相同时频资源上发射的选择以支持DL合作中继。 As a result, the target node 220 may be received from the relay station 118 is received for the allocation of frequency resources, while adjacent relay station 119 will transmit on the same time-frequency resource to support DL cooperative relaying selection.

[0030] 在复用3策略模式中coop-FFR和传统的基于中继的FFR的不同在于,在coop-FFR中合作FFR小区200边缘移动站可从两个或多个邻近基础终端(中继站110、112、114、116、118和119,服务基站105等)在相同的时间和频率区上接收同时的合作传输,而使用传统FFR这是不允许的。 [0030] In the multiplex mode 3 coop-FFR strategy and traditional relay-based FFR different that cooperation in coop-FFR FFR cell 200 edge mobile station from two or more neighboring base terminal (relay station 110 , 112, 114 and 119, serving base station 105, etc.) reception cooperative transmission simultaneously on the same time and frequency zone, but this is not allowed using traditional FFR's. 例如,当为诸如目标节点220这样的MS分配了用于来自基础终端的接收的特定时频资源时,也将给予邻近基础终端在相同时频资源上发射的选择以支持DL合作中继。 For example, when the time-frequency resource 220 such as when an MS is assigned a particular destination node for receiving from the base terminal, the neighboring infrastructure terminals will also be given on the same time-frequency resources for transmitting the selection to support DL cooperative relaying. 因此,合作FFR小区200边缘移动站不仅避免了来自邻近基础终端的主要干扰,基础终端还被用于有利地实现合作多样性和功率效率增益。 Therefore, co-FFR cell 200 edge mobile station not only to avoid major interference from neighboring base terminal, base terminal is also used advantageously to achieve cooperation diversity and power efficiency gains.

[0031] 下行链路数据由服务基站105发送,且所有中继站110、112、114、116、118和119能够接收该DL数据并学习服务基站105调度决定。 [0031] downlink data sent by the serving base station 105, and all 110,112,114,116,118 and 119 relay stations can receive the DL data and learn the serving base station 105 scheduling decisions. 并且,在基于正交频分多址(OFDMA)的资源分配的情况下,其中服务基站105在中继区域中正交地调度打算送给不同中继站110、112、114、116、118和119的数据,每个中继站能监听到其他中继站的数据和控制信息(MAP等)。 And, in the case where the resource allocation based on orthogonal frequency division multiple access (OFDMA), wherein the serving base station 105 in the relay zone intended for scheduling orthogonally different relay stations 110,112,114,116,118 and 119 data, each relay station can listen to the data and control information other relay stations (MAP, etc.). 因此,在调度合作中继传输所需的附加带宽的方面,预期合作的间接成本非常小。 Thus, in terms of scheduling cooperative relaying additional bandwidth required for transmission, indirect costs expected cooperation is very small. 当在调度和调整DL合作中继传输的控制信息(例如附加MAP等)方面有一些附加间接成本时,可应用已知的纠正方法来最小化这样的成本。 When there are some additional overhead cost in scheduling and adjusting DL cooperative relay transmission control information (e.g. additional MAP, etc.), the known correction method can be applied to minimize such costs.

[0032] 图3是涉及通信发射节点、两个中继节点和通信接收节点的实现合作分数频率复用的分级调度和资源管理方案的实施例。 [0032] Figure 3 relates to communications transmit node, two relay nodes to achieve cooperation fraction receiving node and the communication frequency reuse Example hierarchical scheduling and resource management programs. 在图4中说明了通信发射节点410、第一中继节点420、第二中继节点430和通信接收节点440或目标节点和合作者节点450的实施例。 In Figure 4 illustrates the communications transmit node 410, a first relay node 420, a second embodiment of a relay node 430 and the receiving communication node 440 and the cooperator node or destination node 450. 通信发射节点410可以是服务基站105,通信接收节点440可以是目标节点220,中继节点420和430可以是中继站110、112、114、116、118和119的任意两个,并且合作者节点450或邻居节点可以是移动站、用户站560 (图5)或另一个基站或中继节点。 Communications transmit node 410 may be a serving base station 105, the receiving node 440 may be a communication target node 220, the relay node 420 and 430 can be any two relay stations 110,112,114,116,118 and 119, and the cooperator node 450 or neighbor node may be a mobile station, a user station 560 (FIG. 5) or the other base station or relay node. 为了支持DL合作中继和先进的基于中继的干扰管理策略,用于中继辅助的蜂窝网络的调度和资源管理技术的发展是必须的。 To support the development of cooperation DL relay and relay-based advanced interference management strategies for the relay-assisted cellular network scheduling and resource management technology is a must. 在合作中继和coop-FFR方案中,要求多个中继站110、112、114、116、118和119的同时传输或服务基站105和一个或多个中继站110、112、114、116、118及119的同时传输,以便以协同的方式发射,使得它们发生在相同的时间/频率(TF)并且具有协同的MCS和选取的合作传输协议。 In cooperative relaying and the coop-FFR scheme, require a plurality of relay stations 110,112,114,116,118 and 119 simultaneously transmit or serving base station 105 and one or more relay stations 110,112,114,116,118 and 119 simultaneous transmission to transmit in a synergistic manner, such that they occur at the same time / frequency (TF) and having a coordinated MCS and the selected cooperative transmission protocol.

[0033] 虽然在服务基站105处的集中调度可以完成该任务,但是由于在测距(ranging)、带宽要求和网络入口方面引起的复杂化它不是一个优选的方法。 [0033] Although the centralized dispatch service station 105 can accomplish this task, but because of the method in the distance (ranging), and network bandwidth requirements due to the complexity of the entrance areas it is not a preferable. 替代地,可使用两层分级(或者混合)调度方案。 Alternatively, you can use two hierarchical (or mixed) scheduling scheme. 第一层是分布式调度,它以非合作方式服务移动站。 The first layer is distributed scheduling, it is a non-cooperative way to serve the mobile station. 第二层是集中调度,它服务受益于合作中继的MS (例如合作者节点450)的特定集合。 The second layer is a centralized scheduling, it is a specific set of services to benefit from cooperative relaying MS (such as co-node 450). 尽管对于大多数MS的资源分配依赖于分布式调度,但关于能够受益于DL合作中继的MS的调度决定,通过基站的一些级别的基站集中协调是可能的。 Although the majority of MS resource allocation depends on distributed scheduling, but on the DL cooperative relaying can benefit from the MS scheduling decisions, coordination is possible through some level of centralized base station. 在该上下文中,中继站110、112、114、116、118和119使用分布式调度创建它们自己的调度,但是服务基站105可为中继站110、112、114、116、118和119下行链路传输创建特定的分配以实现有限的集中协调和分级调度。 In this context, the relay stations 110,112,114,116,118 and 119 using distributed scheduling create their own scheduling, but the serving base station 105 may create relay stations 110,112,114,116,118 and 119 for the downlink transmission in order to achieve a specific distribution of limited centralized coordination and hierarchical scheduling. 通知每个中继站110、112、114、116、118和119服务基站105的相关集中调度决定,使得它能在不是由服务基站105分配的时频资源上执行它的分布式调度。 Notify each relay station 110,112,114,116,118 and 119 serving base station centralized scheduling decisions related to 105, so that it can perform its distributed scheduling in a service station instead of the frequency by 105 allocated resources.

[0034] 实现coop-FFR的混合调度方案使用集中协调机制(在基站处的)将即将以中继辅助方式服务的所有用户分类为两组:(i)将被合作地服务的移动站,例如那些在复用3分配下位于中继站小区边缘的并由基站选取用于合作传输的移动站;(ii)将被非合作地服务的移动站,例如,I)那些非常接近特定中继站以使它们在复用I分配下的用户,和2)那些在复用3分配下位于中继站小区边缘的用户,但基站决定这些移动站不应当被合作地服务。 [0034] realize coop-FFR hybrid scheduling scheme uses a centralized coordination mechanism (at the base station) All users will soon relay-assisted approach to service classification into two groups: (i) will be moved to the service station cooperation, such as Those multiplexed by the base station is located in relay station 3 is allocated at a cell edge selection for cooperative transmissions of the mobile station; (ii) will be non-cooperative to serve the mobile station, e.g., I) are very close to a particular relay station so that they are I assign users reuse under and 2) those who reuse 3 allocation in relay station located at the cell edge, but the base station determines these mobile stations should not be serving cooperatively.

[0035] 用户的这种分组可以基于诸如用户位置信息、信道质量指标(CQI)度量以及在基站和中继站处的通信量负载这样的标准得以执行,并且可以通过多个帧得以维持或在逐帧的基础上得以改变。 [0035] This grouping may be based on a user, such as user location information, channel quality indicator (CQI) metrics and traffic at the base station and the relay station at the load such standards are implemented, and can be maintained by a plurality of frames or frame able to change basis.

[0036] 还应当通知中继站这些决定,使得每个中继站知道:(i)它将合作地服务哪个移动站,和它将非合作地服务哪个移动站,以及(ii)哪个时频(TF)区域已被分配用于合作传输,哪个TF区域将被用于非合作传输。 [0036] It should also be notified of these decisions relay station, so that each relay station to know: (i) to which the mobile station will serve cooperatively, and it is non-service cooperation to which mobile stations, and (ii) What is the time-frequency (TF) area Cooperation has been allocated for transmission, which will be used for non-TF regional cooperation in transport.

[0037] 在被分配用于非合作传输的TF区域上,每个中继站可对它被指示非合作地服务的移动站集合执行分布式调度,并且基站不需要帮助对这些移动站的特定TF资源分配。 [0037] In the TF area allocated for non-cooperative transmissions, each relay station may be indicative of its non-serving mobile station set cooperatively perform distributed scheduling, and the base station to the mobile stations without the help of specific TF resource allocation.

[0038] 在被分配用于合作传输的TF区域上,基站的进一步地集中协调将是必须的以指定用户TF资源分配、合作传输方案和MCS选择,并且该信息应当被传送给各个中继站以插入它们的DL-MAP中。 [0038] In the TF region allocated for cooperative transmissions, further centralized coordination of the base station will be necessary to specify the user TF resource assignments, cooperative transmission schemes and MCS choices and this information should be transmitted to the relay stations to be inserted into Their DL-MAP in. 该方法将集中调度的使用限制为仅用于应当被合作地服务的移动站,剩下的移动站可以通过分布式调度得以服务。 This method is limited to the use of centralized scheduling only for the mobile station should be served cooperatively and the remaining mobile stations can be distributed through the service scheduling.

[0039] 用于实现coop-FFR方案的分级调度方案的一个例子在两跳中继辅助的DL通信设置的图3中示出。 [0039] An example for implementing coop-FFR scheme hierarchical scheduling scheme in the two-hop relay-assisted communications settings DL Figure 3 shows. 在该图中,在DL-MAP中的COOP-MAP携带与关于在合作中继协议下服务的移动站的基站集中调度决定有关的信息。 In this figure, the DL-MAP of COOP-MAP mobile station to carry and on relay protocol services in cooperation with the base station centralized scheduling decisions related information. 在下一DL子帧中,中继站在它们自己的DL-MAP中包括C00P-MAP,还为在分布式调度下服务的移动站创建它们自己的分配。 In the next DL subframe, the relay station their own DL-MAP includes C00P-MAP, but also create their own allocation for a mobile station in a distributed scheduling service. [0040] 回到图3中,通信发射节点410发射带有首部或前同步码312和包括基本信道(FCH)314的信息体的数据块310,以提供数据用户的基础数据服务、下行链路(DL)映射316、包括调度和调制编码方案信息的合作者映射(COOP-MAP) 318、上行链路映射(UL-MAP) 320、中继站I数据322、中继站2数据324和合作者数据326。 Basic data services [0040] Referring back to FIG. 3, with the communications transmit node 410 transmitting portion or previous data block preamble 312 and includes a fundamental channel (FCH) message 314 of body 310 to provide data users, a downlink (DL) map 316, a cooperator map comprises scheduling and modulation coding scheme information (COOP-MAP) 318, an uplink map (UL-MAP) 320, relay station I data 322, relay station 2 data 324, and cooperator data 326. 放置在数据块310开始、用于帧同步的前同步码312包括补充数据,并且可包括数据块310处理信息。 Placed in the data block 310 begins, a preamble 312 for frame synchronization comprises supplemental data, and data block 310 may include a processing information. 图4的第一中继节点420接收包括第一中继节点数据块首部332以及第一中继节点数据分组334和336的第一中继节点数据块330。 Figure 4 is a first relay node includes a header portion 420 receives a first relay node data block 332 and the first relay node data packets 334 and 336 of the first relay node data block 330.

[0042] 在第二DL子帧348中,第一中继节点420向通信接收节点440 (目标节点或用户站)发射具有第一中继节点前同步码352、第一中继节点基础信道354、第一中继节点DL MAP 356、第一中继节点COOP-MAP 358、第一中继节点UL-MAP 360、第一中继节点C00P-DATA 362和中继站I数据364的第一中继节点数据块350。 [0042] In a second DL sub-frame having 348, first relay node 420 transmits to the receiving communication node 440 (target node or subscriber station) before the first relay node preamble 352, first relay node 354 based channel , first relay node DL MAP 356, first relay node COOP-MAP 358, first relay node UL-MAP 360, first relay node C00P-DATA 362, and relay station data I first RN 364 350 block of data. 类似地,在第二DL子帧348中,第二中继节点向通信接收节点440发射具有第二中继节点前同步码372、第二中继节点基础信道374、第二中继节点DL MAP 376、第二中继节点COOP-MAP 378、第二中继节点UL-MAP380、第二中继节点C00P-DATA 382和中继站2数据384的第二中继节点数据块370。 Similarly, in the second DL sub-frame 348, second relay node to transmit to the communication before receiving node 440 has a second relay node preamble 372, second relay node based channel 374, second relay node DL MAP 376, second relay node COOP-MAP 378, second relay node UL-MAP380, second relay node C00P-DATA 382, and relay station 2 data 384.

[0043] 所讨论的分级调度和资源管理技术也可以应用于一般基于中继的蜂窝网络,以支持除合作中继以外的也需要基站集中协调的诸如串行干扰消除技术这样的传输技术。 [0043] hierarchical scheduling and resource management techniques discussed can also be applied to general relay-based cellular networks to support other than cooperative relaying also requires centralized coordination of the base station interference cancellation technique such as transmission technology. 如以前一样,可为将不由任何先进合作中继或先进干扰管理技术服务的用户执行分布式调度。 As before, you can not help any user to the advanced cooperative relaying or advanced interference management techniques and services to perform distributed scheduling.

[0044] 通信接收节点440可使用根据使用诸如通用分组无线电系统(GPRS)、增强型数据率的全球演进(EDGE)或第三带无线(3G)这样的适当蜂窝标准的基于蜂窝的通信进行通信,虽然本实施例不受限于此。 [0044] The receiving node 440 may use communication according to use such as a General Packet Radio System (GPRS), Enhanced Data rates for Global Evolution (EDGE), or third band wireless (3G) such as the appropriate cellular communication standard based on a cellular communication Although the present embodiments are not limited thereto. 在另外的实施例中,可以采用其他无线通信标准,例如但不限于由电气和电子工程师协会(IEEE)802.11定义的通信、无线保真(W1-Fi)和IEEE802.16微波存取全球互通(WiMAX)系列标准。 In further embodiments, other wireless communication standards may be employed, such as, but not limited to, by the Institute of Electrical and Electronics Engineers (IEEE) 802.11-defined communication, wireless fidelity (W1-Fi), and Worldwide Interoperability for Microwave Access IEEE802.16 ( WiMAX) series of standards.

[0045] 在中继辅助的蜂窝系统中,由于有多个源的干扰干扰管理变得更复杂。 [0045] In a relay-assisted cellular system, interference due to the plurality of sources of interference management becomes more complex. 例如在DL模式中,由移动站观察到的干扰可起因于(i)来自其他基站的同信道干扰,(ii)来自邻近基站小区中中继站的同信道干扰和(iii)来自其他基础终端(基站和/或中继站)的小区内干扰。 For example, in DL mode, observed by the mobile station to the interference may be due to (i) co-channel interference from other base stations, (ii) co-channel interference from neighboring base station cells in the relay station and (iii) from other infrastructure terminals (base station and / or relay stations) of intra-cell interference. 由于将需要大量的协调来同时避免干扰和以有效方式利用TF资源,多个源引起的干扰使得难于以协作形式抑制干扰。 Since the amount of coordination needed to simultaneously avoid interference and use TF resources in an efficient manner, the interference caused by a plurality of sources makes it difficult to suppress interference in the form of collaboration. 并且,由于天线自由度(在MMO-MUD中)和跟踪/抑制可能干扰所需的IC消除层(在SIC中)的数量巨大,使用诸如MIMO多用户检测(MUD)和/或串行干扰消除(SIC)技术这样的技术的干扰抑制方法的设计也更困难。 Further, since the antenna degrees of freedom (MMO-MUD in) and tracking / inhibition may interfere with the desired number of layers of the IC to eliminate (SIC in) is huge, such as the use of MIMO multi-user detection (MUD) and / or interference cancellation Such interference technology (SIC) technique suppression method is also designed to be more difficult. 进一步地,诸如合作中继这样的技术涉及在给定TF资源中多个基础终端的同时传输,增加了在相同TF处对其他传输的潜在干扰。 Further, techniques such as cooperative relaying involve such in a given TF resource simultaneous transmission of a plurality of base terminal, increasing the potential interference to other transmissions at the same TF. 在基于合作传输的干扰抑制方法遭遇到这样的困难的情况下,可结合随机化传输和概率干扰抑制技术的使用来使用coop-FFR方案。 The difficulties encountered in such cooperative transmission interference suppression method based on the situation, can be combined with random probability of transmission and interference mitigation techniques to use coop-FFR scheme. [0046] 在一个例子中,MS识别对在它至期望的基站或中继站的链路上的传输造成最大干扰的基站和中继站。 [0046] In one example, MS identification of its transmission on the link to the desired base station or a relay station of the maximum interference caused by base stations and relay stations. 该信息随同其他参数(例如信道质量指标、干扰测量、主要干扰者数目等)由移动站报告给它的中继站或基站,在报告给中继站的情况下,中继站将该信息中继给基站。 This information along with other parameters (e.g. channel quality indicators, interference measurements, number of dominant interferer like) reported by the mobile station to its relay station or base station, reporting to the relay station in the case, the relay station for relaying information to the base station. 该基站与其他基站共孚引起最大干扰或引起超过给定彳目道阈值的干扰的基站和中继站标识和其他相关参数,其他基站又可向它们各自的中继站通知该信息。 The base station and other base stations to cause the most interference or co-fu caused exceeds a given limit value of the left foot mesh interference base station and relay station identity and other relevant parameters, but also to the other base stations to their respective relay station notifies the information. 在该协调期间的最后,每个基站和中继站知道在哪个链路上它需要随机化传输,以及对于各种动作应当考虑哪个概率判定标准。 Finally, each of the base station and the relay station during the coordinated know on which it needs to randomize the transmission link, and for a variety of actions which should be considered the probability criteria. 将被随机化的链路集合由概率干扰抑制媒体接入控制(PIM-MAC)控制。 The set of links to be randomized by probabilistic interference mitigation medium access control (PIM-MAC) control. 对于各种动作的概率判定标准可基于由系统几何(system geometry)和移动站位置确定的平均SINR条件,以及服务质量(QoS)要求、通信量情况和用户优先级,因此在基站和中继站之间仅需要周期性更新和协调。 The probability of various criteria may be based on the operation of the system geometry (system geometry) average SINR conditions and mobile station position determination, as well as quality of service (QoS) requirements, traffic conditions and user priorities and therefore between the base station and the relay station requires only periodic updates and coordination. 对于诸如路由、合作中继和链路自适应这样的不同动作可设计不同的概率判定标准。 For such as routing, cooperative relay and link adaptation actions can be designed so that different probabilities of different criteria.

[0047] 使用开发的概率判定标准,每个基站和中继站基于各种观察系统和信道参数以及预定义质量阈值,确定每条PIM-MAC链路将被选取的动作。 Probability [0047] The criteria used to develop, for each base station and the relay station based on various observed system and channel parameters and the predefined quality threshold, determining each PIM-MAC link will be selected actions.

[0048] 在基于中继的蜂窝网络中的概率干扰抑制导致了以下方法:i)概率中继和路由:对邻近基站小区或中继站小区造成太多干扰的中继站可不被基站调度者选取用于路由,即使采用的路由算法可能指示通过该特定中继站的多跳路由获得最佳端到端链路质量。 [0048] In the method of interference suppression leads to the following relay cellular network based on the probability that: i) Probabilistic relaying and routing: for neighboring base station cell or relay station cell cause too much interference relay station may not be selected for routing the base station scheduler , even if the routing algorithm is used to obtain the best possible indication of the end to end link quality through the multi-hop route to a specific relay station.

[0049] ii)概率合作和模式选取:用于到移动站的DL合作中继传输的目的具有良好信道质量以帮助另一中继站的中继站在一定概率上将不被基站调度,因为基站认识到该中继站对邻近基站小区或中继站小区造成太多干扰。 [0049] ii) Probabilistic cooperation and mode selection: for the purpose of DL cooperative relay transmission to a mobile station with good channel quality to assist another relay station relay standing a certain probability of the base station will not be scheduled, because the base station recognizing that relay station on the adjacent cell base station or repeater station cell cause too much interference. 类似地,应当使用何种合作中继模式或是否应当采用合作的确定是以具有分配给每一模式的预定义概率的随机方式执行的。 Similarly, what kind of cooperation should be used or whether the relay mode should be used to determine the cooperation is based on a random approach has predefined probability distribution for each mode of execution. 除了合作中继模式的选取之外,概率模式选取还可应用于(i)基于中继的FFR,即用于确定在各种中继站小区区域中将使用的复用因子(例如复用I对复用3),和(ii)决定是否应当在基站小区和中继站小区中的各种区域中使用先进干扰抑制技术。 In addition to co-relay mode selected, the probability model selection can be applied to (i) relay-based FFR, that is used to determine the complex in a variety of relay stations that will be used by the cell area factor (such as reuse of complex I with 3), and (ii) determine whether there should be a variety of regional and relay stations in the base station cell cell interference suppression in the use of advanced technology.

[0050] 在一个实施例中,在无线通信网络中用于抑制干扰的系统包括被配置为通过包括合作者节点的多跳路由在第一频带和时隙与目标节点通信的通信节点、被配置为与目标节点通信的中继节点,中继节点在第二频带和时隙上操作,以及被配置为至少基于信道阈值随机化来自通信节点的多个传输用于同信道干扰避免的媒体访问控制器。 System [0050] In one embodiment, in a wireless communication network for suppressing interference comprises is configured to include a multi-hop routing partner nodes in a first frequency band and time slot communication node communicating with the target node, configured the relay node to the target node in communication, the relay node operating on the second frequency band and time slot, and configured to based at least on channel threshold randomizing a plurality of transmission from the communications node for co-channel interference avoidance MAC device.

[0051] 根据一些实施例在图5中不出了一种干扰抑制系统500。 [0051] According to some embodiments not in Fig. 5 with noise suppression system 500. 该干扰抑制系统500包括服务基站105、中继站118和用户站560。 The interference suppression system 500 105, relay station 118 and user station 560 comprises a serving base station. 服务基站105和服务中继站118通常是由用户站560基于用户站560从服务基站105和/或中继站118接收的相关信号强度选取的。 Serving base station 105 and relay station 118 services typically selected based on the user station 560 from the serving base station 105 and / or relay station 118 related to the intensity of the signal received by the subscriber station 560. 干扰抑制系统500可包括一个或多个其他基站,表示为基站502、基站504和基站506。 Interference suppression system 500 may include one or more other base stations, denoted as base station 502, the base station 504 and the base station 506. 服务基站105具有媒体访问控制器(MAC) 532,中继站118具有MAC 582,用户站560具有MAC562。 Serving base station 105 having a media access controller (MAC) 532, relay station 118 has a MAC 582, the subscriber station 560 has MAC562. MAC 532、582和562包括对本领域普通技术人员来说众所周知的、在此不描述的功能和结构组件。 MAC 532,582 and 562 includes a pair of ordinary skill in the present art is well known, the functional and structural components not described herein. 这些在无线领域中对于所有基站来说通用的功能和结构组件在此被称为传统MAC操作。 These areas in the wireless base station, common to all the functions and structure of the components in this tradition is known as MAC operations.

[0052] 在一些实施例中,MAC 532、582和562各自包括适用于同信道干扰避免(CIA)的新元件,被成为CIAMAC 580。 [0052] In some embodiments, MAC 532,582 and 562 each include a new element suitable for co-channel interference avoidance (CIA), and known as CIAMAC 580. 由于MAC 532、582和562继续支持其他在此没有描述的MAC功能,所以所有服务基站105、中继站118和用户站560都具有传统MAC和CIA MAC 580两个功能性。 Since MAC 532,582 and 562 continue to support other MAC functions not described herein, all serving base station 105, relay station 118 and subscriber station 560 has two conventional MAC 580 and CIA MAC functionality. [0053] 在一些实施例中,CIAMAC 580包括同信道干扰避免570、传输随机化540、传输随机化590、物理层优化550和物理层优化595。 [0053] In some embodiments, CIAMAC 580 includes co-channel interference avoidance 570, transmission randomisation 540, transmission randomisation 590, physical layer optimization 550 and physical layer optimization 595. 如图5所示,同信道干扰避免570由用户站560执行,而传输随机化590和物理层优化595由中继站118执行,传输随机化540和物理层优化550由基站502、504、506和105执行。 5, co-channel interference avoidance 570 is performed by the user station 560, while transmission randomisation 590 and physical layer optimization 595 performed by a relay station 118, transmission randomisation 540 and physical layer optimization 550 by the base station 502,504, 506 and 105 carried out.

[0054] 根据一些实施例,在图6中图示了一种无线邻域600,以有助于理解图5的干扰抑制系统。 [0054] According to some embodiments, in FIG. 6 illustrates a wireless neighborhood 600, to facilitate understanding of the interference suppression system of Figure 5. 无线邻域600包括七个小区610,每个都具有基站,BS1-BS7 (统称为基站BS)。 Wireless neighborhood 600 includes seven cells 610, each having a base station, BS1-BS7 (collectively, base stations BS). Trace

述为移动设备的、表示为MpM2.....M9的用户站560被用于整个无线邻域600中(统称为 Referred to as mobile devices, denoted MpM2 ..... M9 user station 560 are used throughout the wireless neighborhood 600 (collectively referred to as

用户M)。 The user M). 用户M的数量可随时间改变。 M is the number of users may change over time. 线C1表示用户M和基站BS之间的期望链路。 Line C1 indicates the desired link user M and the base station BS. 对于移动用户M1存在到基站BS1的期望链路C1。 For mobile subscriber M1 base station BS1 to the presence of the desired link C1. 由于基站使用相同的频率在信道I (C1)上发射,这样的传输可能对在其他小区中的移动站造成干扰。 Since the base station using the same frequency transmit channel I (C1) on, such a transmission in the mobile station may cause interference to other cells. 例如,在图6中,产生了来自基站BS4和BS2的在相同信道上的干扰,在两方均表示为U。 For example, in Figure 6, resulting in interference from the base station BS4 and BS2 in the same channel, are expressed in both U.

[0055] 干扰抑制系统500从用户站560 (或目标节点)开始。 [0055] interference suppression system 500 from the user station 560 (or the target node) begins. 用户站560通知服务基站105和中继站118来自无线邻域600中某些其他基站或中继站的干扰。 560 notify the serving base station 105 and relay station 118 or some other base station interference from relay station 600 in the wireless neighborhood subscriber station. 在图5中,显示了从用户站560到服务基站105的反馈链路534以表示该步骤。 In Figure 5, shown from the user station 560 to the serving base station 105 to the feedback link 534 indicates that step. 然后,服务基站105与已有干扰报告的无线邻域600中的其他基站共享该干扰报告。 Then, the serving base station 105 shares the interference report and 600 existing interference reports in wireless neighborhood other base stations. 在图5中在服务基站105和在干扰抑制系统500中的每个基站502、504和506之间显示了干扰报告链路520。 In Figure 5 between the serving base station 105 and the interference suppression system 500. Each base station 502, 504 and 506 show the interference report link 520. 在一些实施例中,一旦在无线邻域600中的所有基站都意识到该干扰,基站确定是否执行传输随机化540。 In some embodiments, once all the base stations in the wireless neighborhood 600 are aware of the interference, the base station determines whether to perform transmission randomisation 540. 和其他传输一样,随机化的传输根据通过物理层优化550获得的参数发生。 Like other transport, randomized transmission according to the parameters obtained by optimizing the physical layer 550 occur. 并且,在一些实施例中,中继站118确定是否执行传输随机化590。 Also, in some embodiments, the relay station 118 determines whether to perform transmission randomisation 590. 和其他传输一样,随机化的传输根据通过物理层优化595获得的参数发生。 Like other transport, randomized transmission according to the parameters obtained by optimizing the physical layer 595 occur.

[0056] 在一些实施例中,同信道干扰避免570根据图7的流程图操作。 [0056] In some embodiments, the co-channel interference avoidance 570 operating according to the flowchart of FIG. 尽管操作可由多个用户同时执行,但操作由用户站560(或在无线邻域600中用户M的其中之一)执行。 Although operations performed by multiple users simultaneously, but the operation performed by the subscriber station 560 (or one of them in the wireless neighborhood 600 in the user M). 用户站560识别在到服务基站的其链路上对传输造成最大干扰的基站502 (或中继站)(方框700)。 Identifying the subscriber station 560 on its link to the serving base station transmission causing the most interference to base station 502 (or a relay station) (block 700). 然后用户站560通过比较干扰载波比(ICR)与阈值(r),作出是否向它的服务基站105和可能它的中继站118通知该干扰的决定(方框710)。 Then the subscriber station 560 by comparing the interfering carrier ratio (ICR) to a threshold (r), and a decision is made whether to 105 (block 710) it may notify the relay station 118 to its serving base station interference.

[0057] 如果没有超过阈值(方框720),干扰不足以触发用户站560的通知。 [0057] If the threshold is not exceeded (block 720), the interference is not sufficient to trigger a notification of the user station 560. 否则,用户站560向它的服务基站105和可能它的中继站118提交造成最大干扰的基站和中继站标识(方框730)。 Otherwise, the user station 560 to submit to its serving base station 105 and possibly its relay station 118 cause the most interference base station and relay station identification (block 730). 在一些实施例中,提交操作构成用户站560、服务基站105和中继站118之间的一次或多次CIAMAC触发信息的交换。 In some embodiments, the submission operation constitutes the user station 560, the serving base station triggers one or more CIAMAC 105 and the exchange of information between the relay station 118. 如在此使用的,“CIAMAC触发”是指导致用户站560或服务基站105或中继站118调用它们各自MAC 562、582、532的CIAMAC 580的事件。 As used herein, "CIAMAC trigger" refers to cause the user station 560 or the serving base station 105 or the relay station 118 to call their respective MAC CIAMAC 580 of events 562,582,532. 换句话说,CIAMAC触发是在用户站560确定干扰超过阈值时。 In other words, CIAMAC trigger is determined when the interference at the user station 560 exceeds a threshold value.

[0058] 服务基站105将由用户站560报告的信息发送给在无线邻域600中的其他基站(方框740)。 Information [0058] The serving base station 105 by the user station 560 transmits to a report in the wireless neighborhood 600 of other base station (block 740). 此时,每个基站都知道被报告干扰所在的链路,这些链路是在其中传输将被最优地随机化的链路(方框750)。 In this case, each base station knows where the link is interference report, in which the transmission of these links is to be optimally randomized link (block 750). 在一些实施例中,CIAMAC触发可以基于由系统几何和用户位置确定的平均SINR情况。 In some embodiments, CIAMAC trigger may be based on the average SINR is determined by the system geometry and location of the user. 在这些实施例中,CIAMAC触发在无线邻域中的其他基站间被周期性地更新和协调。 In these embodiments, CIAMAC trigger is updated and coordinated among other base stations in the wireless neighborhood periodically.

[0059] 一旦触发了CIA MAC 580,服务基站105中MAC 532的传输随机化540和服务中继站118中MAC 582的传输随机化590被启动。 [0059] Once triggered the CIA MAC 580, MAC transmission in the serving base station 105 in MAC 532 and transmission randomisation 540 service relay 118 582 randomized 590 is activated. 在无线邻域中的其他基站和中继站同样地启动到用户站560的传输随机化。 In other wireless base stations and relay stations in the neighborhood starts to transmit the same manner as the user station 560 randomization. 图8是示出根据一些实施例在无线邻域600中执行以随机化传输的操作的流程图。 8 is a flowchart performed to randomize the transmission operation in the wireless neighborhood 600, according to some embodiments is shown. 在图8中的操作可由在无线邻域600中的所有基站BS和所有中继站执行,但是为了简明起见,在流程图中仅指出一个基站和一个中继站。 Operation In Figure 8 by all base stations BS and all relay stations perform wireless neighborhood 600, but for the sake of simplicity, in the flow chart indicated only one base station and a relay station.

[0060] 基站和中继站识别将被分析的链路(方框800),这些链路是服务基站105、中继站118和报告干扰的用户站560之间的链路。 [0060] base station and relay station identify the links to be analyzed (block 800), the link 105, the link 118 and the relay station reports interference between user stations 560 serving base station. 基站和中继站为CIAMAC链路确定信道阈值(方框810)。 Base station and relay station link is determined for CIAMAC channel threshold (block 810). 如果在给定链路上的信道增益没有超过“信道阈值”(方框820),则没有发生到用户站560的传输(方框830)。 If a given channel gain on the forward link does not exceed a "channel threshold" (block 820), there is no occurrence of a transmission to the subscriber station 560 (block 830). 否则,服务基站105和服务中继站118向具有优化物理层参数的用户站560发射(方框840)。 Otherwise, the serving base station 105 and the serving relay station 118 with optimized physical layer parameters to the subscriber stations 560 transmit (block 840). 因此,在一些实施例中,传输概率和超过“信道阈值”的概率成比例。 Thus, in some embodiments, the transmission probability and the probability "channel threshold" exceeds proportional.

[0061] 然而,在传输随机化540、590和物理层优化550、595能够发生之前,干扰抑制系统500确定CIAMAC触发的阈值。 [0061] However, before the transfer randomization 540,590 and 550,595 physical layer optimization can occur, interference suppression system 500 determines CIAMAC trigger threshold. 在一些实施例中,每个用户站560作出决定以触发CIA MAC580。 In some embodiments, each subscriber station 560 to make a decision to trigger the CIA MAC580. 该触发基于将来自每个基站的所测量的干扰载波比(ICR)和阈值的相比较。 The triggering is based on the interfering carrier from each base station by comparing the measured phase ratio (ICR), and thresholds. 在一些实施例中,基于每用户一个强干扰的假设推导该阈值。 In some embodiments, each user based on the assumption of a strong interference derive the threshold value. 对多个干扰者的扩展是简单的。 Extended plurality interferers is straightforward. 在一些实施例中,其中有一个干扰者,通过将使用CIA MAC 580的系统的实际吞吐量(goodput)和没有CIAMAC系统的实际吞吐量相比较来推导最佳阈值。 In some embodiments, where there is a interferers, by using the actual throughput CIA MAC 580 of the system (goodput) and the actual throughput of the system does not CIAMAC comparing derive the optimal threshold. 对于最佳阈值,CIA MAC的实际吞吐量大于传统传统MAC的实际吞吐量。 For optimal threshold, CIA MAC actual throughput is greater than the actual tradition traditional MAC throughput. 计算ICR阈值的值作为SNR的函数。 ICR threshold value calculation as a function of SNR.

[0062] 干扰抑制系统500可采用替换的触发CIAMAC 580的方法。 [0062] Interference Suppression Method trigger CIAMAC 580 system 500 may be replaced. 这些方法包括但不限于基于一个以上的强干扰者比较实际吞吐量,使用基于位置的信息或用户站560间的协调来确定被严重干扰的用户等。 These methods include, but are not limited to those based on more than one strong interference more practical throughput, using coordinate information based on location or between a user station 560 to determine severely interfered users, etc. 通过前述的分数频率复用的执行,可进一步的避免干扰。 By the aforementioned fractional frequency reuse of execution, can further avoid interference.
