each relay station can also be used for different channels in their respective coverage area edge 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 of the mobile station in the channel region 140, and the channel region 150, 160 and 170 provide the mobile station with a lower frequency reuse. 在小区100的这些区域中降低频率OT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。 Reduce

under the service station 105 and relay station 110, 112, 114, 116, 118 and tighter frequency reuse 119. 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^l艮务,以避免同信道干扰,这些正交波段被分配 In some embodiments, located in the cell 100 'MS edges will have three orthogonal band (or sub-sets) of three frequency-multiplexed ^ l Gen Service, in order to avoid co-channel interference, these bands are orthogonal

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。 To the relay station, wherein each relay station located on the opposite side of the cell 100, that is shown in Figure 1, the channel region 150, 160 and 170 corresponding to three separate 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 one of the three alternative modes of relay stations provide two subchannels. 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, the six multiplex mode can be used as a relay station each provides its own channel, need a total of six orthogonal channel allocation.

在图1所示的实施例中,位于紧邻服錢站105 (在第一频道120内)的MS在OT 1策略下l则艮务,位于近邻中继站UO、 112、 114、 116、 118和119 其中之一(在第三频道140内)的小区100 ,用户在复用1策略下MI艮务。 In the embodiment shown in FIG. 1, it is located close to the money service station 105 MS (in the first channel 120) in OT 1 strategy that works to l is located in neighboring relay station UO, 112, 114, 116, 118 and 119 One cell (in the third channel 140) 100 users in reuse 1 strategy that works to MI. 可选地,对远离服皿站105 (在第二频道区域130内)和^f可中继站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应用飾3策略,以确鹏些MS的因频谱飾而导致的干扰损失最小化。 Alternatively, to stay away from serving dish station 105 (130 in the second channel region) and ^ f can relay stations 110 and 116 (150 in the fourth channel region), 112 and 118 (170 in the fifth channel region) and interference lost 114 and 119 MS (in the sixth channel 160.)

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。 Figure 2 is a relay-based fractional frequency reuse cell-cell co-generation cooperation FFR fractional frequency 200 schematic multiplexing illustrated in FIG. 1, 100 has. 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職敷卜围、通常经历差SINR剝牛的MS的目的,下〗滩路(DL)合作中继技术与基于中继的FFR概念相结合。 Interference management for successful cooperation to benefit the relay mode BU located at the cell functional deposited around the cellular system, usually through poor SINR MS stripping cattle purpose, under way in beach (DL) relay technology cooperation with Based on the concept of combining FFR relay. 产生的合作多样性禾呦率效«益可导致小区職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。 Cooperation diversity Wo Yo rate generator efficiency «benefits can result in significant performance gains cell MS of the post; roughly comparable provided by the receiver maximum ratio combining (MRC) technology gain.

在存在如图2所示的基于中继的FFR策略的情况下,为小区ii^ MS包括DL合作中继支持意1«,可由多个基础终端(服#«站105和/或中继站110、 112、 114、 116、 118和119)通过^ffl诸如分布式空时编码(STC)、分布式波束形成、合作糊餘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 ,五频道170区域内) 的MS。 In the presence of 2-based case relay FFR strategy for the district ii ^ MS include support DL cooperative relaying Italy 1 «, by a plurality of base terminal (service #« station 105 and / or a relay station 110, 112, 114, 116, 118 and 119) by ^ ffl such as distributed space-time coding (STC), distributed beamforming, cooperation than as a relay-paste their simultaneous transmission, to serve in the complex with 3 areas ( That is 130, the fourth channel region in the second channel region 150, the sixth channel 160, channel 170 in the region of five) of the MS.

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(S腿) 的目标节点220提供增强的干扰管理能力。 In Figure 2, the application to the cooperative relaying technique has a poor signal to interference plus noise ratio (S leg) of the target node 220 provides 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。 Diversity and power efficiency gains resulting collaboration led to the target node 220 (such as cellular phones, personal digital assistants (PDA), a portable PC, handheld computer devices and other forms of 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,月艮务基站105等)产生。 Cooperation diversity such as distributed space-time coding (STC), the beam is formed by using a distributed, cooperative and other cooperative relay multiplexing technology to provide simultaneous or nearly simultaneous transmission of multiple infrastructure terminals (relay station 110, 112, 114, 116, 118 and 119, that works to month base station 105, etc.) to produce.

基于中继的FTR和DL合作多样性的结合使得目标节点220會嫩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 ,移动站被称为合作FFR (coop-FFR)。 FTR and DL relay-based partnership combines diversity so that the target node 220 will tender together with the power efficiency advantages of cooperative relaying together while achieving FFR interference suppression advantages of diversity and cooperation, for cooperation FFR cell 200, the mobile station is called Cooperation FFR (coop-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 coop-FFR region between 160 210 using a downlink (DL) mode Cooperative diversity operation. 结果,目标节点220可从中继站118接CT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 connected to CT in the time-frequency resource allocation received from the relay station 118, while adjacent relay station 119 will transmit on the same frequency resources to support DL cooperative relay selection.

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^K卩近基础终端(中继站110、 112、 114、 116、 118和119,月艮,站105等)在相同的时间和频率区上接收同时的合作传输,而i顿传统EFR这是不允许的。 Coop-FFR and traditional relay-based FFR different that cooperation FFR cell 200 edge mobile station in coop-FFR can (relay station 110 from two or more ^ K Jie near base terminal in multiplexed mode 3 strategy, 112, 114, 116, 118 and 119, on Burgundy, station 105, etc.) to receive cooperation simultaneous transmissions on the same time and frequency area, but i Dayton traditional EFR it is not allowed. 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,也将乡好邻近基础终端在相同时频资源上微的选择以支持DL合作中继。 For example, when the frequency resources such as such as MS 220 assigned specific target node for receiving from the base terminal, also good near the village on the basis of the same terminal in the choice of frequency resources to support micro DL cooperative relay. 因此, 合作FFR小区200 ,移动站不仅避免了来自邻ifiS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, cooperation FFR cell 200, the mobile station not only to avoid major interference from adjacent ifiS base terminal, base terminal is also used advantageously to achieve cooperation diversity and power efficiency gains.

下《滩足繊据由服縫站105发送,且所有中继站110、 112、 114、 116、 118和119會,接收该DL数据并学习服,站105调度决定。 Under "Beach Foot Xian data sent by the server sewing station 105, and all the relay stations 110, 112, 114, 116, 118 and 119 will be receiving the DL data and Learning Services, station 105 scheduling decisions. 并且,在基于正交频分多址(OFDMA)的资源分配盼瞎况下,其中服縫站105在中继区域中正交地调度打算送给不同中继站IIO、 112、 114、 116、 118禾口119的«,每个中继站倉滥听到其他中继站的娜和控帝赔息(MAP等)。 And, in case the allocation of resources based on blind hope orthogonal frequency division multiple access (OFDMA), in which clothes sewing station 105 in the relay zone intended for scheduling orthogonally different relay stations IIO, 112, 114, 116, 118 Wo Port 119 «, each relay station warehouse indiscriminate hear other relay stations and control Dili na lose interest (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 relay transmission bandwidth required for additional, indirect costs expected cooperation is very small. 当在调度和调整DL合作中继传输的控帝瞻息(例如附加MAP等)方面有一些附加间接财时,可应用已知的纠正方fefe最小化这样的成本。 When there is some additional indirect fiscal adjustment in scheduling and DL cooperative relay transmission control Timor-looking information (such as an additional MAP, etc.), it can be applied to correct known side fefe minimize such costs.

时间/频率(tf)并且具有协同的mcs和选取的合作传irtH义。 Time / frequency (tf) and has coordinated and selected co-mcs pass irtH justice.

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)、带宽要求禾,络入口方面弓胞的复杂化它不是一个ttt的方法。 Although centralized dispatch service station 105 may accomplish this task, but due to distance (ranging), bandwidth requirements Wo, it's not a complicated method of network entry terms ttt cells of the bow. 替代地,可使用两层分级(或者混合)调度方案。 Alternatively, you can use two fractionation (or a mix) scheduling scheme. 第一层是分布式调度,它以非合作方划艮务移动站。 The first layer is distributed scheduling, it is a non-partner plan that works to the mobile station. 第二层是集中调度,它服务魏于合作中继的MS (例如合作者节点450)的特定集合。 The second layer is a centralized scheduling, it serves a specific set Wei in cooperation relaying MS (such as cooperator node 450). 尽管对于大多数MS的资源分配依赖于分布式调度,但关于能够魏于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 for resource allocation depends on distributed scheduling, but the scheduling can Wei on the MS DL cooperative relaying decisions, some level of centralized coordination by the base station is possible. 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,但是服錢站105可为中继站110、 112、 114、 116、 118和119下行^S各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 to create their own schedules, but serving money station 105 may relay stations 110, 112, 114, 116, 118 and 119 downlink ^ S each Transfer to create a specific allocation in order to achieve a limited central coordination and hierarchical scheduling. 通知每个中继站IIO、 112、 114、 116、 118和119服皿站105 的相关集中调度决定,使得它能在不是由服,站105分配的时频资源上执行它的分布式调度。 Notify each relay station IIO, 112, 114, 116, 118 and 119 dish stand related centralized scheduling decision 105, so it can not by the service station on the implementation of its distributed scheduling 105 is assigned frequency resources.

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,1)那些非常^fi特定中继站以使它们在飾1分配下的用户,和2)那些在复用3分配下位于中继站小区纖的用户,但基站决定这些移动站不应当被合作地服务。 Achieve coop-FFR hybrid scheduling scheme uses a centralized coordination mechanism (at the base station) to all users of an impending service free relay-assisted manner into two groups: (i) will be moved to the service station cooperation, such as those in the complex 3 assigned by the base station is located at the edge of the selected cell relay station for cooperative transmissions mobile station; (ii) the mobile station will be non-cooperative to serve, for example, 1) ^ fi those very specific relay station so that they are decorated 1 user-assigned under and 2) those in multiplex 3 assignment in the user relay station cell fibers, but the base station determines the mobile stations should not be serving cooperatively.

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。 This grouping may be based on the user, such as user location information, channel quality indicator (cqi) measurements and are implemented in such a standard base station and relay station traffic load and can be maintained by a plurality of frames, or frame by frame basis be changed.

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)明P个时频(TP)区域已被分配用于合作传输,明P个TF区繊各I細于非合作传输。 You should also notify the relay station these decisions, so that each relay station knows: (i) which the mobile station will serve cooperatively, and it will non-cooperation which the mobile station to service, and (ii) a time-frequency Ming P (TP) area has is allocated for cooperation transmission, a TF area next P 繊 all I fine cooperation in the non-transmission.

在被分配用于非合作传输的TF区域上,齡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。 On the TF area allocated for non-cooperative transmission, age relay station may be instructed its cooperation to non-serving mobile station to a collection of distributed scheduling, and the base station without the help of specific resource allocation for these mobile stations TF.

在被分酉调于合作传输的TF区耻,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。 Being divided unitary transmission tune in cooperation shame TF region, the base station further centralized coordination will be necessary to specify the user TF resource allocation, cooperative transmission scheme and MCS selection, and this information should be transmitted to the relay stations to insert their DL-MAP in. 该方法将集中调度的i顿限制为i观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。 The method of centralized scheduling concept i i Dayton limited to the mobile station should be served cooperatively and the remaining mobile stations can be distributed through the service scheduling.

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。在该图中,在DLMAP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。在下一DL 子帧中,中继站在它们自己的DL-MAP中包括COOP-MAP,还为在分布式调 For implementing coop "an example of hierarchical scheduling scheme FFR scheme in two-hop relay DL-assisted communication setting is shown in Figure 3.

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。 Hierarchical scheduling and resource management techniques discussed can be applied to general relay-based cellular networks to support cooperation in addition to the relay station also requires centralized coordination, such as interference cancellation technology such 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.

通信接收节点440可JOT根据^ffl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。 JOT receiving communication node 440 may according to Global Evolution ^ ffl such as General Packet Radio System (GPRS), Enhanced Data rate (EDGE), or third band wireless (3G) cellular standards such as appropriate based cellular communication for 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(正EE) 802.11定义的通信、无线保真(Wi-Fi)和正EE 802.16微波存取全球互通(WiMAX)系列标准。 In a further embodiment, it is possible to use other wireless communication standards, such as, but not limited to, by the Institute of Electrical and Electronics Engineers (positive EE) 802.11 defined communication, wireless fidelity (Wi-Fi) and n-EE 802.16 Worldwide Interoperability for Microwave Access ( WiMAX) series.

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。 In the relay-assisted cellular system, because there are multiple sources of interference 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,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) from a neighbor, co-channel interference station cell relay station and (iii) from another base terminal ( The base station and / or relay station) 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TP资源,多个源弓胞的干扰使得难于以助、作形式抑制干扰。 Because would require a lot of coordination to avoid interference and use TP resources in an efficient manner, a plurality of sources of interference bow cells makes it difficult to help, as a form of interference suppression. 并且, 由于天线自由度(在画O-MUD中)和足跟宇V抑制可能干J^f需的IC消除层(在SIC中)的数量巨大,^f顿诸如MMO多用户检测(MUD)禾口减串行干扰消除(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 (in the painting O-MUD) and the heel Yu V inhibition may dry J ^ f need a huge amount of IC eliminate layers (SIC in) the, ^ f Dayton MMO such as multi-user detection (MUD) Hekou reduce interference cancellation techniques such interference (SIC) technology Rejecting design more difficult. 进一步地,诸如合作中继这样的技术涉及在给定TT资源中多个基础终端的同时传输,增加了在相同TP W"其他传输的潜在干扰。在基于合作^1J的干扰抑制方法M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。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。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。该基站与其他基站共享弓胞最大干扰或弓胞超过给定信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。在该协调期间的最后,每个基站和中继站知道在哪,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。将被随机化的链路集合由概率干扰抑帝蝶体接入控制(PIM-MAC) 控制。对于各种动作的概率判定标准可基于由系统几何(system geometiy)和移动站位置确定的平均S證斜牛,以及服务质量(QoS)要求、通信量瞎况和用户优先级,因此在基站和中继站之间仅需要周斯性更新和协调。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。 Further, such as cooperative relaying technique involves simultaneously in a given TT resource base terminal of the plurality of transmission, increasing the same TP W "other potential interference transmission in. M to such cooperation ^ interference suppression method based 1J Under difficult circumstances, it can be combined with random probability of transmission and interference mitigation techniques to use coop-FFR scheme. In one example, MS identification of transport it to the desired base station or relay station links cause the most interference The base station and the relay station. This information along with other parameters (e.g. channel quality indicators, interference measurements, the main interferers number, etc.) by the mobile station reports to its relay station or base station, in the report to the relay station, the relay station the information relaying to the base station. The station maximum interference with other base stations share bow cell or bow cell exceeds interference on a given channel threshold of the base station and relay station identification and other relevant parameters, other base stations but also to their respective relay station notifies the information during the coordination Finally, each base station and relay station knows where the road it needs to randomize transmission, as well as the probability for a variety of actions which should be considered criteria would be randomized link set by the probability of interference suppression emperor butterfly body access control ( PIM-MAC) control. For the probability of various actions of criteria may be based on the system geometry (system geometiy) and average S permits the mobile station position determination oblique cattle, as well as quality of service (QoS) requirements, traffic conditions and user preferences blind level, and therefore between the base station and the relay station needs only weeks Andean updates and coordination for such routing, adaptive cooperative relaying and link different actions can be designed such different probability criteria.

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PM-MAC链路将I雌取的动作。 Developed using probability criteria, each base station and relay station based on various observation system and channel parameters, and predefined quality threshold determined each PM-MAC link will I take estrogen action.

在基于中继的蜂窝网络中的概率干扰抑审得致了以下方法: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{跌用的路由算法可能指示通过该特定中继站的多瑕璐由获得最佳端到端鹏质量。 In the relay-based cellular network trial have caused the probability of interference suppression following methods: i) the probability of the relay and routing: neighboring base station cell or cell cause too much interference relay station relay station may be a base station scheduler selection for routing, the routing algorithm {fall may indicate that by using this particular flaw Lu relay station more quality from the best end-to-peng get.

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。 ii) the probability of selection and modes of cooperation: cooperation for the purpose DL relay transmission of mobile stations with good channel quality to help relay another relay station stood a certain probability of the base station will not be scheduled, because the base station recognizes the relay station near cell base station or a relay station cell cause too much interference. 类似他,应当^ffi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, he should ^ ffi relay mode or what kind of cooperation should be used to determine whether cooperation in a random fashion with a predefined probability distribution for each mode of execution. 除了合作中继模式的选取之外,概^i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i顿的复用因子(例如复用1对OT3),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{顿先进干扰抑制技术。 In addition to selecting cooperative relay mode, almost ^ i type selection can be applied to (i) a relay-based FFR, that is used to determine the complex in a variety of relay stations in the cell area by a factor i Dayton (such as multiplexing 1 pair OT3), and (ii) whether it should be regional in base station cell and the relay station in the cell {Dayton advanced interference suppression technology.

根据一些实施例在图5中示出了一种干扰抑制系统500。 According to some embodiments is shown in Figure 5, a 500 interference suppression system. 该干扰抑制系统500包括服,站105、中继站118和用户站560。 This interference suppression system 500 includes a service station 105, relay station 118 and subscriber station 560. 月艮,站105和服务中继站118通常是由用户站560基于用户站560 /Al艮皿站105和/或中继站118接收的相关信号强度选取的。 Gen month, service station 105 and relay station 118 is usually caused by the user station 560 based on the user station 560 / Al Gen dish station 105 and / or relay station 118 related to the intensity of the received signal selected. 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. 服縫站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MAC 562。 Service station 105 has a slit Media Access Controller (MAC) 532, relay station 118 has a MAC 582, the subscriber station 560 has a MAC 562. MAC 532、 582 和562包括对本领域普通技术人员来说^m周知的、在此不描述的功能和结构组件。 MAC 532, 582 and 562 include those of ordinary skill ^ m known, functional and structural components are 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 functional and structural components referred to herein as a traditional MAC operations.

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CIAMAC580。 In some embodiments, MAC 532, 582 and 562 each include a new element suitable for co-channel interference avoidance (CIA), and is become CIAMAC580. 由于MAC 532、 582和562继续支持其他在此没有描述的MAC功能,所以所有服錢站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 the MAC 532, 582 and 562 continue to support other MAC functions not described here, so all the money the service station 105, relay station 118 and subscriber station 560 has 580 two traditional MAC and CIA MAC functionality.

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3M优化595。 In some embodiments, CIAMAC 580 including 570 to avoid co-channel interference, transmission randomized 540, 590 transmission randomized, physical-layer optimization optimization 595 550 and was 3M. 如图5所示,同信道干扰避免570由用户站560执行,而^tr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, to avoid co-channel interference 570 performed by the user station 560, and ^ tr randomized 590 and 595 physical layer optimization performed by the relay station 118, transmission randomized 540 and 550 from the physical layer to optimize base station 502, 504, 506 and 105 execution.

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 的干扰抑帝係统。 According to some embodiments, in FIG. 6 illustrates a wireless neighborhood 600, to facilitate understanding of the interference suppression system of Figure 5 Di. 无线邻域600包括七个小区610,每个都具有基站,BS广BS7 (统称为基站BS)。 Wireless neighborhood 600 includes seven cells 610, each having a base station, BS wide BS7 (collectively, base stations BS). 描述为移动设备的、标为M,、 M2、 ...、 M9的用户站560 被用于旨无线邻域600中(统称为用户M)。 Described as mobile devices, denoted M ,, M2, ..., M9 user station 560 is intended to be used in the wireless neighborhood 600 (collectively referred to as user M). 用户M的数量可随时间改变。 M is the number of users can change over time. 线qg用户M和基站BS之间的期望^。 Qg users expect line between M and the base station BS ^. 对于移动用户Mi存在到基站的期望链路q。 For mobile users q Mi desired link to the base station exists. 由于基站使用相同的频tt信道1 (Cl)上发射,这样的传输可倉树在其他小区中的移动站造成干扰。 Since the base station using the same frequency channel transmission tt 1 (Cl) on such transmission may warehouses tree mobile stations in other cells cause interference. 例如,在图6中,产生了来自基站BS4 和BS2的在相同信3Ii:的干扰,在两方均表示为id。 For example, in Figure 6, resulting in a base station BS4 and BS2 same letter 3Ii in from: the interference, in which both parties expressed as id.

干扰抑帝係统500从用户站560 (或目标节点)开始。 Emperor interference suppression system 500 from the user station 560 (or destination 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 notification service base station 105 and relay station 118 or some other base relay station interference from neighboring wireless subscriber station 600. 在图5中,显示了从用户站560到服皿站105的反«路534以表示该步骤。 In Figure 5, the display from the user station 560 to station anti dish clothes «Road 105, 534 to indicate that step. 然后,月艮,站105与已有干扰报告的,邻域600中的其他基站共享该干扰报告。 Then, on Burgundy, station 105 share the report with the existing interference interference reports, 600 NEIGHBORHOOD other base stations. 在图5中在服縫站105和在干扰抑制系统500中的針基站502、 504 和506之间显示了干扰报告链路520。 In Figure 5, the seam in the service station 105 and the interference suppression systems in 500-pin base station 502, interference report shows the link between 520 504 and 506. 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,随机化的传辦艮据通过物理层优化550获得的参数发生。 And other transmission, the parameters randomized Chuan Ban Gen optimization according to the physical layer 550 obtained 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鹏优化595获得的参数发生。 Like other transport, randomized 595 transport optimization parameters obtained through the objective occurrence according to Peng.

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。 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日m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 the operation by multiple users on the same day m row, but the operation performed by the user station 560 (or one of them in the wireless neighborhood 600 M of the user). 用户站560识另赃到服縫站的其链路谓传输造臓大干扰的基站502 (或中继站)(方框700)。 The subscriber station 560 to identify another stolen clothes sewing station made its transmission link that Zang large interference base station 502 (or 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«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), it is made whether the service «station 105 and may determine its relay station 118 notifies the interference (block 710).

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。 If the threshold is not exceeded (block 720), the interference is not sufficient to trigger the inform the user station 560. 否则, 用户站560向它的服錢站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 its 105 service stations and money may submit 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、服錢站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 commit operation constitutes a user station 560, one or more service stations CIAMAC money triggered the exchange of information between 105 and 118 of the relay station. 如在此{顿的,"CIAMAC触发'是指导致用户站560劍艮錢站105或中继站118调用它们各自MAC 562、 582、 532的CIAMAC 580的事件。换句话说,CIAMAC 触发是在用户站560确定干OT过阈值时。 Dayton herein {e.g., "CIAMAC trigger 'means leading to the subscriber station 560 sword Gen money station 105 or a relay station 118 to call their respective MAC CIAMAC 580 events 562, 582, 532. In other words, CIAMAC is triggered in the user station 560 determines that the threshold value OT dry.

服#«站105将由用户站560报告的信息総给在无线邻域600中的其他基站(方框740)。 Clothes # «station 105 by the user station 560 to report the information 総 in the neighborhood of 600 other radio base station (block 740). 此时,每个基站都知道被报告干扰所在的链路,这纖路是在其中^lT将被最^i也随机化的链路(方框750)。 In this case, each base station knows where the link is reported interference, which is where the towpath will be most ^ lT ^ i also 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斯性地更新和协调。 In these embodiments, CIAMAC triggered by the weekly updates of Sri Lanka and coordination among other base station radio neighborhood.

一旦触发了CIA MAC 580,月艮縫站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 !鹏动。 Once triggered the CIA MAC 580, MAC transmission 532 in monthly Burgundy sewing station 105 randomized 540 and the relay station MAC transmission services 582 118 randomized 590! Peng move. 在无线邻域中的其他基站和中继站同样地启动至,户站560的传输随机化。 In other wireless base stations and relay stations in the neighborhood of the same start to the transmission station 560 households 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 is shown according to some embodiments. 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 Fig. 8 by all the base stations BS and all relay stations perform wireless neighborhood 600, but for the sake of simplicity, only one indicated in the flowchart base station and a relay station. 基站和中继站识别将被分析的^IE各(方框800),这些链路是服皿站105、 中继站118和报告干扰的用户站560之间的链路。 ^ IE base station and the relay station will be analyzed to identify the respective (block 800), these links are serving dish station 105, relay station 118 and the link reporting interference between subscriber station 560. 基站和中继站为CIAMAC链路确定信道阈值(方框810)。 Base stations and relay stations for the CIAMAC link determine channel threshold (block 810). 如果在给定链路上的信道增益没有超迚'信道阈使' (方框820),则没有发生到用户站560的传输(方框830)。 If the gain to the channel on a given link does not exceed the 迚 'channel threshold so' (block 820), there is no occurrence of the transmission to the subscriber station 560 (block 830). 否则,月艮,站105 和服务中继站118向具有优化物理层参数的用户站560娜(方框840)。 Otherwise, on Burgundy, service stations 105 and 118 to the relay station with optimized physical layer parameters of the subscriber station 560 Na (block 840). 因此, 在一些实施例中,传输概率和超迚'信道阈使'的概率成比例。 Thus, in some embodiments, the transmission probability 'channel threshold so that' the probability and ultra 迚 proportional.

然而,在传输随机化540、 590和物理层优化550、 595會,发生之前,干扰抑制系统500确定CIAMAC触发的阈值。 However, the transmission randomized 540, 590 and 550 physical layer optimization, before 595 will 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CIAMAC 580。 In some embodiments, each subscriber station 560 to trigger a decision CIAMAC 580. 该触发基于将来自每个基站的所测量的干扰载波比(ICR)禾口阈值的相比较。 The trigger-based carriers from each base station will interfere with the measured phase comparison ratio (ICR) Hekou threshold. 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^hT扰者的扩展是简单的。 ^ HT interference by multiple extensions is simple. 在一些实施例中,其中有一1^F 扰者,M将^ffl CIA MAC 580的系统的实际吞吐量(goodput)和没有CIA MAC系统的实际吞吐量相比,推导最佳阈值。 In some embodiments, where there is interference by a 1 ^ F, M actual throughput ^ ffl CIA MAC 580 system (goodput) and no CIA MAC actual system throughput compared to 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 greater than traditional conventional MAC actual throughput. 计算ICR阈值的值作为SNR的函数。 ICR threshold value calculated as a function of SNR.

干扰抑制系统500可采用替换的触发CIAMAC 580的方法。 Interference suppression system triggered CIAMAC 580 Method 500 can be replaced. 这些方g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 include, but are not limited to, square g based on more than one strong interferer more practical throughput, or information based coordination between the subscriber station 560 to determine the location of a user or the like is seriously disturbed. 舰前述的分数频率翻的执行,可进一步的避免干扰。 Ship aforementioned fractional frequency turn of execution, can further avoid interference.
