Description

一种多用户协同通信触发方法及设备
技术领域 本发明涉及无线通信技术领域， 尤其涉及一种多用户协同通信触发方法及设备。 背景技术 随着移动通信技术的快速发展， 出现了多种制式的移动通信系统，例如， GSM ( Global System of Mobile communication, 全球移动通讯系统） 网络、 GPRS ( General Packet Radio Service,通用分组无线服务技术）网络、 WCDMA ( Wideband Code Division Multiple Access , 宽带码分多址） 网络、 CDMA-2000网络、 TD-SCDMA ( Time Division-Synchronous Code Division Multiple Access ,时分同步码分多址）网络、 WiMAX ( Worldwide Interoperability for Microwave Access, 全球^:波互联接入） 网络等。 这些移动通信系统除了提供语音通信业 务之外， 通常还提供数据通信业务， 因此用户可以使用这些移动通信系统所提供的数据通 信业务来上传和下载各种数据。
现有技术中釆用 CoMP ( Coordinated Multipoint, 多点协作传输）来提高处于小区边缘 终端的可靠性， 釆用 CA ( Carrier Aggregation, 载波聚合）来提高用户的吞吐率， 但如果终 端自身环境恶化， 终端的数据传输的吞吐率和 /或可靠性将会急剧下降。
目前， MUCC ( Multiple UE Cooperative Communication, 多用户协同通信 ) 的概念被 提出。 在多用户协同通信技术中， 由于 D2D ( Device to Device , 设备与设备 )通信技术实 现终端与终端的通信， 使终端间相同支撑成为可能， 进而基站发送给某个终端的数据可以 发送给该终端附近的其它终端 （即支撑终端， 表示为 S-UE ), 再通过终端之间的近距离通 信技术转发给最终目的终端 （即受益终端， 表示为 B-UE )。 这样就可以在多个终端中选择 信道条件好的终端作为 S-UE, 从而通过多用户分集增益提升用户边缘速率， 进而提升频谱 利用效率。
D2D技术中， 近距离发现技术和近距离通信技术是多用户协同通信的基础。 近距离发 现技术中， 需要启用近距离发现功能的设备向近距离业务服务器发起开启近距离发现功能 的请求后， 近距离业务服务器为发起请求的设备分配专门用于近距离发现的广播信息， 即 近距离标识或称 D2D标识（D2D Code ), 用于实现全球近距离发现设备的唯一标识。 获得 D2D Code的设备， 一方面以预先定义的规则向外广播携带有 D2D Code的信号来宣布自己 在当前位置的存在， 以帮助其它设备发现自己； 另一方面， 以预先定义的规则监听周围其 它设备广播的携带有 D2D Code的信号， 当设备接收到其它设备广播的携带有 D2D Code的 信号时，或者在接收到其它设备广播的携带有 D2D Code的信号且与该其它设备进行物理层 交互尝试成功后， 表示发现该其它设备出现在近距离范围之内。
现有多用户协同通信技术尚未给出协同通信的触发机制， 也没有给出如何及时准确地 找到终端的协同通信用户的方案。 发明内容 本发明实施例提供了一种多用户协同通信触发方法及设备， 用以基于用户邻近关系实 现多用户协同通信触发决策。

图 1为一种多用户协同通信的示意图， 其中， S-UE1、 S-UE2和 B-UE是处于同一 WI-FI ( Wireless Fidelity ) 网络内的终端， S-UE1、 S-UE2是 B-UE的多用户协同通信的支撑用户， B-UE是受益终端， eNB ( evolution NodeB , 演进节点 B, 即基站）通过 UU接口向 S-UE1、 S-UE2发送下行数据， S-UE1和 S-UE2通过 WI-FI链路将数据发送给 B-UE。 由于不同路径在 不同时刻的信道质量可能不同， 釆用多用户协同通信技术可以选择每个时刻最好的链路或 者多个链路进行通信传输， 从而使 B-UE获得多用户的分集增益。 图 1仅以 UE间的第二跳链 路为 WI-FI链路为例描述， 但第二跳链路不仅限于 WI-FI链路， 还可以是其它 D2D通信标准 中规定的 D2D链路类型。
多用户协同通信技术要提升频谱利用率， 提升用户的服务速率， 尤其是边缘速率， 需 要解决的一个重要问题就是如何及时触发多用户协同通信，以及如何为 B-UE准确找到协同 用户集。 本发明实施例给出了一种根据 UE邻近关系触发多用户协同通信的机制， 以及为 B-UE准确选择协同用户集的方案。
为了便于理解本发明实施例， 首先对本发明实施例描述中所遵循的约定进行说明：
( 1 )本发明实施例中所涉及的近距离通信技术可以包括： WLAN ( Wireless Local Area Networks, 无线局域网）、 蓝牙 （bluetooth )或 Zigbee (即一种低速近距离传输的无线网络 协议）等， 此处不——列举；
( 2 )本发明实施例中所涉及的 UE均为具备近距离发现功能的 UE, 并开启了近距离发 现功能。
下面结合附图对本发明实施例进行详细描述。
参见图 2, 本发明实施例提供的 MUCC触发判决总体流程示意图， 该流程可包括： 步骤 201： 网络设备获取 UE邻近关系信息， 根据获取到的 UE邻近关系信息确定 B-UE 及其邻近 UE。 所述 UE邻近关系信息可表示为邻近 UE列表， 邻近 UE列表中至少包括 UE的 唯一标识， 比如 UE的 D2D Code。 其中， 网络设备获取 UE邻近关系信息的方式可以包括以 下方式中的一种：
方式 1: 通过 UE上报。 具体的， UE可通过测量上报方式， 将通过近距离发现技术所测 量到的 UE作为邻近 UE进行上报。 网络设备可根据终端的能力决策出 B-UE和有能力提供支 撑服务的 S-UE。
方式 2: 通过网络设备自身进行感知。 具体的， 网络设备可通过自动感知技术感知 UE 间的邻近关系。 由于 UE邻近关系是通过基站感知得到的， 无需 UE上报 UE邻近关系信息， 因此减少了网络资源开销。
上述方式 1中， 上报 UE邻近关系的 UE可以是 B-UE, 或者是有能力提供支撑服务的 S-UE, 或者是这两种 UE。 如果上报 UE邻近关系的 UE是 B-UE, 则网络设备可根据该 B-UE 的上报内容直接得到该 B-UE的邻近 UE;如果上报 UE邻近关系信息的 UE是有能力提供支撑 服务的 S-UE, 则网络设备可综合各 S-UE上报的内容得到 B-UE的邻近 UE, 比如 S-UE1和 S-UE2上报的邻近 UE中均包括 B-UE1 , 则 B-UE1的邻近 UE中包括 S-UE1和 S-UE2。
步骤 202: 网络设备根据获取到的 B-UE的邻近 UE信息， 获取该 B-UE的邻近 UE的信道 质量信息。
步骤 203: 网络设备根据获取到的 UE信道质量信息， 判决是否触发多用户协同通信， 并在判定触发多用户协同通信时， 根据获取到的 UE信道质量信息确定协同用户集， 即， 为 B-UE确定协同通信的 S-UE。
下面以网络设备是基站为例， 结合具体实施例对本发明实施例进行详细描述。
实施例一
参见图 3, 为本发明实施例一提供的多用户协同通信触发流程示意图。 该流程中， 基 站根据 B-UE上报的邻近 UE列表获取相关 UE的信道质量， 并以此进行多用户协同通信触发 判决。 如图所示， 该流程可包括以下步骤：
步骤 301 : UE向基站上报通过近距离发现技术所测量到的邻近 UE列表。 上报邻近 UE 列表的 UE可以是 B-UE或 S-UE, 也可以包括 B-UE和 S-UE。 该列表中包含邻近 UE的唯一标 识， 比如 UE的 D2D Code, 进一步的， 列表中还可包括 UE的 PCI ( Physical Cell ID, 物理小 区标识）等。
在近距离发现技术中， UE通常会发送 D2D Discovery消息 （也称 Disco very Beacon (发 现信标）信号）， 该信号中携带该 UE的 D2D Code, 用于 UE间的信号探测和相互发现。 本发 明实施例中， UE可在接收到邻近 UE广播的携带有 D2D Code的 D2D Discovery消息来发现其 邻近 UE, 也可以通过社交应用来发现其邻近 UE。
步骤 302: 基站根据 UE上报的邻近 UE列表， 获取 B-UE及其邻近 UE的 UU口链路信道质 量信息。
具体实施时， 同前所述， 如果上报 UE邻近关系的 UE是 B-UE, 则基站可根据该 B-UE 的上报内容直接得到该 UE的邻近 UE;如果上报 UE邻近关系信息的 UE是有能力提供支撑服 务的 S-UE,则网络设备可综合各 S-UE上报的内容得到 B-UE的邻近 UE。基站获得 B-UE的邻 近 UE后， 获取该 B-UE及其邻近 UE的 UU口链路信道质量信息。
步骤 303: 基站根据获取到的该 B-UE及其邻近 UE的 UU口链路信道质量信息， 判决是 否触发多用户协同通信， 若判定触发多用户协同通信， 则执行步骤 304, 否则等待下次判 决。
步骤 304: 基站根据获取到的该 B-UE的邻近 UE的 UU口链路信道质量信息为该 B-UE确 定协同通信的 S-UE。
步骤 305: 基站在为该 B-UE确定协同通信的 S-UE后， 发起多用户协同通信流程， 包括 向参与多用户协同通信的 UE ( B-UE和该 B-UE的 S-UE )发送协同通信的配对请求。
下面对图 3所示流程中的各个步骤的优选实现方式分别进行详细描述。
图 3所示流程的步骤 301中， B-UE可根据测量上报规则向基站上报通过近距离发现技术 所测量到的邻近 UE列表。
该测量上报规则可以规定上报类型， 上报类型可包括周期上报、 事件触发上报， 以及 周期上报和事件触发上报相结合。 相应的， B-UE根据该测量上报规则， 按照设定周期将通 过近距离发现技术所测量到的邻近 UE列表上报给基站，或者在特定事件发时将通过近距离 发现技术所测量到的邻近 UE列表上报给基站，或者将上述周期上报和事件触发上报方式相 结合。 其中， 特定事件可以是： 当 B-UE通过接收到的 D2D Disco very (即 Disco very Beacon ) 信号探测到邻近 UE的 UD口（即 B-UE与邻近 UE间的第二跳链路的接口 M言号质量高于一定 门限情况下进行邻近关系上报。 该门限可以是每个 UE所特有的， 可以由网络侧配置， 也可 以是 B-UE通过对网络 RS (参考信号） 的测量得到。
该测量上艮规则还可以规定上 方式，上艮方式包括通过 RRC( Radio Resource Contro , 无线资源控制协议） 消息上报， 或者通过 MCE ( MAC Control Element, MAC控制单元， MAC: Media Access Control, 媒体接入控制）上报。 相应的， B-UE可以通过 RRC消息， 以类似 Measurement Report (测量报告） 的方式上报邻近 UE的信息， 也可以通过 MCE的方 式上报邻近 UE的信息。
该测量上报规则还可以规定上报内容， 相应的， B-UE所上报的邻近 UE列表中包含用 于区分 UE的标识， 比如 D2D Code, 进一步的还可包含 PCI等。
进一步的， 该测量上报规则所规定的上报内容还可以包括 B-UE的 UU口链路信道质量 信息。 为了减少 1^上艮的信息量， 可预先依据 RSRP ( Reference Signal Receiving Power, 参考信号接收功率）或者 CQI ( Channel Quality Indicator, 信道质量指示符）将信道质量划 分多个衰落等级， 或者将信道质量转化为 RSRP等级或者 CQI等级。 UE在对 UU口链路进行 信道质量测量时， 可基于驻留小区的 RS ( Reference Signal, 参考信号）完成下行测量， 将 测量结果转化为衰落等级参数、 RSRP等级参数或 CQI等级参数， 将转化后的等级参数携带 于上报给基站的邻近关系信息中发送给基站。 图 6A示出了 UE发送的 D2D Discovery消息的格式， 该消息格式仅为一种示例。 图 6A所 述的消息格式中， 各部分的说明如下：
PCI ( PCI )字段： 1字节长度， 用于承载发送者 UE的 PCI, 该 PCI可以是 Truncated (截 断） PCI, 以减少上报的信息量；
MUCC Capacity字段： 4比特长度， 用于承载发送者 UE的 MUCC能力信息；
UU Energy Level字段： 4比特长度， 用于承载发送者 UE与基站间的 UU口链路大尺度衰 落和路径损耗的能力等级信息；
D2D Code列表： 用于承载发送者 UE通过近距离发现技术所检测到的邻近 UE的信息， 主要包括邻近 UE的 D2D Code。
进一步的， 为了减少系统开销， 提升协同通信的效率和测量效率， 上述测量上报规则 中还可规定过滤规则， 使 B-UE按照该过滤规则对通过近距离发现技术测量得到的邻近 UE 进行过滤， 将过滤后的邻近用户的信息上报给基站。 B-UE根据过滤规则所进行的过滤操作 可包括以下中的一种或组合（比如将以下过滤规则 1分别与过滤规则 2、 3、 4或 5进行组合）： 过滤规则 1 : B-UE根据邻近 UE的 MUCC能力进行过滤。 比如， 如果邻近 UE具备支持 S-UE的能力， 则上报该邻近 UE的信息， 否则将该邻近 UE过滤掉。 在近距离发现技术中， MUCC能力通常携带于 D2D Code发送或与 D2D Code—起发送， 由 UE广播出去， B-UE可根 据接收到的邻近 UE广播的信息获得该邻近 UE的 MUCC能力。 通过该过滤操作， 可将具备 一定 MUCC能力的邻近 UE筛选出来进行上报。
过滤规则 2: B-UE根据该 B-UE和各邻近 UE的 UU口链路信道质量进行过滤。 在一种优 选的方式中， B-UE将邻近 UE所测量到的 UU口链路信道质量与该 B-UE所测量到的 UU口链 路信道质量进行对比， 将 UU口链路信道质量好于或不低于该 B-UE的邻近 UE进行上报。 比 如， 如果 B-UE判断邻近 UE1与基站间的大尺度衰落小于或等于该 B-UE与基站间的大尺度 衰落， 则将邻近 UE1作为邻近 UE进行上报， 否则不上报邻近 UE1的信息。 进一步的， 在对 UU口链路的大尺度衰落进行比较时， 可考虑 ICIC ( Inter-Cell Interference Coordination, 小 区干扰协调） 的影响。
其中， UE可利用近距离发现技术， 将其测量到的 UU口链路的质量信息以广播方式发 送出去， 比如通过 D2D Code广播出去， 其它 UE (比如 B-UE )可根据接收到的邻近 UE广播 的 D2D Code获得该邻近 UE的 UU口链路信道质量信息。
通过该过滤操作， 可将 UU口链路信道质量不低于 B-UE信道质量的邻近 UE进行上报。 过滤规则 3: B-UE根据各邻近 UE与该 B-UE间的 UD口链路信道质量进行过滤。 一种优 选方式是： B-UE将各邻近 UE与该 B-UE间的 UD口链路信道质量进行排序， 并从 UD口链路 信道质量从高到低的顺序取其中 N ( N的取值可预先设定）个邻近 UE进行上报； 另一种优 选方式是： B-UE将各邻近 UE与该 B-UE间的 UD口链路信道质量与预先设置的阈值（该阈值 可根据 UE所釆用的近距离通信技术等因素来确定）进行比较， 将 UD口链路信道质量高于 该阈值的邻近 UE进行上报。 其中， UE进行 UD口链路信道质量测量的方式同前所述。
过滤规则 4: B-UE根据邻近 UE与该 B-UE的 UD口链路信道质量以及邻近 UE的 UU口链 路信道质量进行过滤， 其中， B-UE获得邻近 UE的 UU口链路信道质量信息以及 UD口链路 信道质量信息的方式同前所述。 在一种优选的方式中， 预先针对 UU口链路和 UD口链路分 别设置权重， B-UE对于测量到的各邻近 UE,将邻近 UE与基站间基于 UU口测量得到信道质 量和邻近 UE与该 B-UE间基于 UD口测量得到的信道质量与各自的权重相乘， 然后再相加， 根据计算结果选取综合信道质量好的邻近 UE进行上报。 比如，在信道质量用大尺度衰落来 表示的情况下，经过上述权重计算后，可将计算得到的大尺度衰落最小的邻近 UE进行上报。 通过该过滤操作，可综合考虑 UU口链路和 UD口链路的信道质量选择信道质量好的邻近 UE 进行上报。
进一步的，在综合考虑 UU口链路和 UD口链路的信道质量进行过滤时， 可结合考虑 UU 口链路和 UD口链路的资源使用情况、 天线配置情况等信息。 比如， 基于 UU口和 UD口的频 谱效用函数进行计算， 即根据用户 UU口的 RB ( Resource Block, 资源块）使用情况和传输 TB ( Transport Block, 传输块） 大小情况折算出其 UU口的频谱效率 （LTE协议中的 CQI即 表征该含义； LTE: Long Term Evolution, 长期演进）； UD口根据釆用的 D2D技术确定频谱 效率的计算方法，在基于 LTE的 D2D技术中可以通过 UD口的传输速率和使用 RB情况折算频 谱效率，在 WI-FI Direct技术中可以通过基于 WI-FI的实际传输业务速率和 S-UE在 UU口使用 的 RB数目进行折算 UD口的频谱效率和 UU口频谱效率； 天线配置方面主要是在频谱效率计 算是需要考虑的因素， 如 2T2R相对 1T2R在低相关信道下会有 2倍的频谱效率增益。
以上各过滤规则以及根据过滤规则进行邻近 UE过滤的方式，仅为优选实现方式，基于 以上原理所实现的过滤规则和相应的过滤方式， 均在本发明的保护范围内。
上述测量上报规则可以通过广播的方式， 由网络设备 (如基站）下发给 UE。 也可以针 对具备 MUCC能力用户为其配置默认的测量上报规则， 比如作为默认规则包含于通信协议 中。
图 3所示流程的步骤 302中， 网络设备根据 UE (包括 B-UE以及该 B-UE上报的邻近 UE ) 的状态， 可釆用不同的方式获取 UE的信道质量。 具体的， 由于 Active (激活）状态的 UE 可向基站上报测量得到的 UU口链路信道质量信息， 因此对于 Active状态的 UE,基站可直接 获得 UE上报的 UU口链路信道质量信息， 比如 CQI或基于 SRS ( Sounding Reference Signal, 探测参考信号）和 /或 DMRS ( Demodulation reference signals, 解调参考信号）测量得到的 信道质量信息等。 其中， CQI是对 UU口下行信道的质量测量， SRS是对上行信道质量的测 量， 在 TDD系统下可以通过信道互易性直接适用于下行； FDD下对于大尺度衰落部分可以 等同。对于 IDLE (空闲）状态的 UE,基站通过寻呼该 UE将该 UE接入系统，该 UE进入 Active 状态后向基站上报 UU口链路的质量信息， 比如 CQI等信道质量信息， 从而使基站能够获得 UE的 UU口链路信道质量。
根据前面对测量上报规则的描述， B-UE可以在上报给网络设备的邻近 UE列表中携带 UE的 UU口链路信道质量信息， 因此网络设备也可根据 B-UE上报的邻近 UE列表获得 UE的 UU口链路信道质量。 在具备支撑能力的 UE也上报邻近关系信息的情况下， 釆用这种在上 报的邻近 UE列表中携带本 UE自身的 UU口链路信道质量信息的方式，对于 B-UE上报的邻近 UE中空闲状态的 UE, 网络设备可以不用寻呼该 UE即可获得该 UE的 UU口链路信道质量， 从而节省了网络资源开销， 以及网络设备和 UE上的寻呼处理开销。
图 3所示流程的步骤 303中，基站根据该 B-UE以及该 B-UE上报的邻近 UE的 UU口链路信 道质量信息，若判断该 B-UE的邻近 UE中有 UE的 UU口链路信道质量不低于该 B-UE的 UU口 链路信道质量，则判定为该 B-UE触发多用户协同通信。比如，基站根据该 B-UE以及该 B-UE 上报的邻近 UE的 UU口链路大尺度衰落和路损等级，如果判断在该 B-UE的邻近 UE中，存在 大尺度衰落和路损等级低于或等于该 B-UE的 UE时， 判定为该 B-UE触发多用户协同通信。
图 3所示流程的步骤 304中， 基站在判决需要为 B-UE触发协同通信后， 进一步的， 可根 据该 B-UE以及该 B-UE上报的邻近 UE的 UU口链路信道质量信息， 从该 B-UE上报的邻近 UE 中， 为该 B-UE确定协同通信的 S-UE。 优选的， 基站根据该 B-UE上报的邻近 UE的 UU口链 路信道质量，选择 UU口链路信道质量不低于该 B-UE的所有邻近 UE或部分邻近 UE (比如按 照信道质量从高到低的顺序， 选择信道质量好的一定数量的邻近 UE ), 作为该 B-UE的协同 通信的 S-UE。
图 3所示流程的步骤 305中， 基站发送的协同通信的配对请求中携带有 B-UE的 D2D
Code, 以及该 B-UE的 S-UE的 D2D Code。 基站可以釆用以下任意一种方式向参与多用户协 同通信的 UE发送协同通信的配对请求：
方式 1: 先向 B-UE发送协同通信的配对请求， 然后向 S-UE发送协同通信的配对请求； 方式 2: 先向 S-UE发起协同通信的配对请求， 然后向 B-UE发送协同通信的配对请求； 方式 3： 并行向 B-UE和 S-UE发送协同通信的配对请求。
根据以上描述， 图 4A和图 4B分别示出了 UE与 eNB的信令交互流程。
图 4A所示的流程中， B-UE上报邻近 UE列表给 eNB; eNB对于该邻近 UE列表中处于
Active状态的 UE, 根据该 UE上报的测量报告获得该 UE的 UU口链路信道质量， 对于该邻近
UE列表中处于 Idle状态的 UE , 通过寻呼该 UE使其进入 Active状态， 根据进入 Active状态后 该 UE上报的测量报告获得该 UE的 UU口链路信道质量； eNB根据获取到的 B-UE及其邻近
UE的 UU口链路信道质量进行多用户协同通信判决， 并在判决为触发多用户协同通信后， 向该 B-UE以及该 B-UE的 S-UE发起协同通信配对请求。
在图 4B所示的流程中， B-UE和 S-UE均上报邻近 UE列表给 eNB, 且在上报的邻近 UE列 表中携带 UU口链路信道质量信息； eNB根据获取到的 B-UE及其邻近 UE的 UU口链路信道质 量进行多用户协同通信判决， 并在判决为触发多用户协同通信后， 向该 B-UE以及该 B-UE 的 S-UE发起协同通信配对请求。
通过以上实施例一的流程可以看出， 网络设备根据 UE上报的邻近 UE列表确定出 B-UE 及其邻近 UE,根据 B-UE及其邻近 UE的 UU口链路信道质量进行 MUCC触发判决， 并为判决 为需要进行 MUCC的 B-UE选择协同用户集（即为 B-UE选择 S-UE ), 从而实现 MUCC的触发 判决，并为 B-UE选取合理的协同集用户，最终提升用户的服务质量、提升网络的整体性能。
实施例二
本实施例在实施例一的基础上， eNB还获取用于提升协同通信判决精度的辅助信息， 并结合该辅助信息为 B-UE选择 S-UE, 从而提高协同通信的效率。 所述辅助信息主要用于 多用户协同通信的辅助判决。 该辅助信息中可包含 B-UE与邻近 UE间的第二跳链路（即 UD 口链路）质量信息， 比如可以是表征 UE间的 UD口链路大尺度衰落和路径损耗的能力等级 ( Energy Level ), 或者辅助信息中可包含 UE的 MUCC能力信息， 或者辅助信息中同时包含 B-UE与 S-UE间的第二跳链路信道质量信息和 UE的 MUCC能力信息。 所述 MUCC能力可包 括： 支持 MUCC能力（是否支持 MUCC ), 支持 B-UE的能力（是否可作为 B-UE ), 支持 S-UE 的能力 （是否可作为 S-UE ), 支持好友作为 S-UE的能力， 支持好友作为 B-UE的能力等等。
下面以 UE上报的邻近 UE列表中包含邻近 UE的 UD口链路信道质量信息为例，对实施例 二的流程进行详细描述。
实施例二的流程基本与图 3所示流程类似， 下面仅对实施例二与实施例一相比有改进 的步骤进行重点说明。
参见图 5, 为本发明实施例二提供的多用户协同通信触发流程示意图。 该流程中， 基 站根据 B-UE上报的邻近 UE列表获取相关 UE的信道质量和辅助信息， 并以此进行多用户协 同通信触发判决。 如图所示， 该流程可包括以下步骤：
步骤 501 : UE向基站上报通过近距离发现技术所测量到的邻近 UE列表， 邻近 UE列表 中包含邻近 UE的 UD口链路信道质量信息。
该步骤中， 上报邻近 UE列表的 UE可以包括 S-UE, 或者包括 B-UE和 S-UE。 邻近 UE列 表中至少包含邻近 UE的唯一标识， 比如 UE的 D2D Code, 还包含用于多用户协同通信判决 的辅助信息， 该辅助信息至少包含邻近 UE的 UD口链路信道质量信息。
具体实施时， 可在上报规则规定上报 UE间的 UD口链路信道质量信息， 此种情况下，
UE可以通过对其所发现的邻近 UE进行 UD口链路的信道质量检测， 得到该 B-UE与该邻近
UE间的 UD口链路信道质量， 并可进一步将检测到的 UD口链路信道质量进行等级化， 比如 可以利用 D2D Discovery (即 Discovery Beacon )信号的信号强度进行 UD口链路的信道质量 检测， 将检测到的信道质量以 RSRP等级或 CQI等级表示， 携带于邻近 UE列表进行上报。 UE也可以通过从其发现的邻近 UE接收到的广播信号（ Discovery Beacon信号） 中获得该邻 近 UE检测出来的并以广播方式发送的 UD口链路信道质量信息， 这要求 UE将检测到的 UD 口链路信道质量信息携带于 D2D Discovery ( Discovery Beacon )信号中发送， 以使其邻近 UE可以获取到其中携带的 UD口链路信道质量信息，在将检测到的 UD口链路信道质量进行 广播之前， 可首先进行等級化处理， 比如可以将检测到的信道质量以 RSRP等级或 CQI等级 表示， 以减少传输的数据量。
同实施例一中的描述， UE所发送的 D2D Discovery消息中还可携带该 UE的 UU口链路信 道质量信息（比如 UU口链路信道质量等级）， 进一步的， 该 UE还可将自己的 MUCC能力携 带于 D2D Disco very消息发送。
图 6A示出了 UE (例如 S-UE )发送的 D2D Discovery消息的格式， 图 6B示出了 B-UE所 上报的邻近 UE列表的格式。
B-UE接收到邻近 UE上报的如图 6A所示的 D2D Disco very消息后， 可根据接收到的 D2d Disco very消息获得邻近 UE的以下信息： D2D Code, MUCC能力信息和 UU口链路信道质量 等级。 B-UE还可以根据该 D2D Discovery消息的信号强度得到该 B-UE与发送该 D2D Discovery消息的邻近 UE的 UD口链路信道质量信息，并可进一步将其量化为 UD口链路信道 质量等级。 在设置了过滤规则的情况下， B-UE可按照前述过滤方式、根据上述信息进行邻 近 UE的过滤。 B-UE将邻近 UE列表上报给基站时， 所上报的邻近 UE的信息至少包括 D2D Code, 还可进一步包括 UU口链路信道质量等级和 UD口链路信道质量等级等信息。 其中， UU口链路信道质量等级信息来自于邻近 UE发送的 D2D Discovery消息， UD口链路信道质 量等級可来自于邻近 UE发送的 D2D Discovery消息，也可以是 B-UE根据 D2D Discovery消息 的信号强度测量得到的。 B-UE上报给基站的邻近 UE列表中可包含邻近 UE的 MUCC能力信 息 （该 MUCC能力信息来自于邻近 UE发送的 D2D Discovery消息）， 也可不用携带邻近 UE 的 MUCC能力信息。
图 6B示出了 B-UE上报的邻近 UE列表中的一个信息单元的格式， 通过该信息单元可以 承载一个邻近 UE的相关信息， 如果需要上报 N个邻近 UE的信息， 则需要 N个该格式的信息 单元。
图 6B所示的邻近 UE列表中的信息单元中， 各部分的说明如下：
PCI字段： 6比特长度， 用于承载邻近 UE的 PCI, 该 PCI可以是 Truncated (截断） PCI, 以减少上报的信息量；
D2D Code: 48比特长度， 用于承载邻近 UE通过近距离发现技术所检测到的邻近 UE的 D2D Code;
UU Energy Level字段： 3比特长度， 用于承载邻近 UE与基站间的 UU口链路大尺度衰落 和路径损耗的能力等级信息； UD Energy Level字段： 3比特长度， 用于承载邻近 UE与 B-UE间的 UD口链路大尺度衰 落和路径损耗的能力等级信息。
需要说明的是， 图 6A和图 6B所示的格式仅为优选实现方式， 凡是能够携带上述信息的 消息格式均应包含在本发明的保护范围之内。
步骤 502: 基站根据 UE上报的邻近 UE列表， 获取 B-UE及其邻近 UE的 UU口链路信道质 量信息和 UD口链路信道质量信息。
该步骤中， 基站可通过实施例一的方式获取邻近 UE的 UU口链路信道质量信息， 也可 根据步骤 501中 UE上报的邻近 UE列表中获得邻近 UE的 UU口链路信道质量信息。
基站在获取 B-UE及其邻近 UE的 UU口链路信道质量信息的基础上， 还根据步骤 501中 UE上报的邻近 UE列表获得用于多用户协同通信判决的辅助信息， 该辅助信息中 UD口链路 信道质量信息， 还可进一步包括 MUCC能力信息。 如果步骤 501中， B-UE上报的邻近 UE列 表中未包含邻近 UE的 MUCC能力信息， 则基站可从存储有 UE信息的设备（如近距离服务 器）获取 B-UE的邻近 UE的 MUCC能力信息。
步骤 503: 基站根据获取到的该 B-UE及其邻近 UE的 UU口链路信道质量信息， 判决是 否触发多用户协同通信， 若判定触发多用户协同通信， 则执行步骤 504, 否则等待下次判 决。
步骤 504: 基站根据该 B-UE的邻近 UE的 UU口链路信道质量信息和 UD口链路信道质量 信息为该 B-UE确定协同通信的 S-UE。
该步骤中， 基站根据 B-UE及其邻近 UE的 UU口链路信道质量以及上述辅助信息， 为该 B-UE选择进行多用户协同通信的 S-UE。 以下列举了几种参考辅助信息为 B-UE选择 S-UE的 优选实现方式：
选择方式 1: 基站根据 B-UE的邻近 UE的 UU口链路信道质量信息， 选择出 UU口链路信 道质量不低于该 B-UE的 UU口链路信道质量的所有邻近 UE,得到该 B-UE的候选 S-UE集合， 再根据该 B-UE与候选 S-UE集合中的各候选 S-UE的 UD口链路信道质量信息， 按照 UD口链 路信道质量从高到低的顺序， 从候选 S-UE集合中选择一个或多个（数量可预先设定）候选 S-UE作为该 B-UE的 S-UE。 为进一步缩小选择范围， 在根据 UU口链路信道质量确定候选 S-UE集合时，可在选择出 UU口链路信道质量不低于该 B-UE的 UU口链路信道质量的所有邻 近 UE后， 再按照 UU口链路信道质量从高到低的顺序从中选择部分邻近 UE, 得到该 B-UE 的候选 S-UE集合。
釆用选择方式 1选择出的 S-UE, 其 UU口链路信道质量不低于 B-UE的 UU口链路信道质 量， 并且该 S-UE的 UD口链路具有较高的质量。
选择方式 2: 基站首先从 B-UE的邻居 UE集合中选择出支持 S-UE能力且 UU口链路信道 质量不低于该 B-UE的 UU口链路信道质量的所有 UE作为候选 S-UE集合， 然后再根据该 B-UE与候选 S-UE集合中的各候选 S-UE的 UD口链路信道质量信息， 按照 UD口链路信道质 量从高到低的顺序， 从候选 S-UE集合中选择一个或多个（数量可预先设定）候选 S-UE作为 该 B-UE的 S-UE。
釆用选择方式 2选择出的 S-UE支持 S-UE能力， 其 UU口链路信道质量不低于 B-UE的 UU 口链路信道质量， 并且该 S-UE的 UD口链路具有较高的质量。
选择方式 3: 釆用两步判决法（包括初始判决和二次判决） 为 B-UE选择 S-UE。
两步判决法的核心是首先判决 B-UE和邻近 UE的 UU口链路信道质量或者说频谱效用， 只有邻近 UE的 UU口链路信道质量不低于 B-UE的 UU口链路信道质量， 才能作为该 B-UE的 候选 S-UE; 然后判决 S-UE的 UD口传输速率要不低于 B-UE的 UU口传输速率， 从而保证整 条 S-UE的链路可以获得频谱效率提升的可性能。 由于 UD口的传输技术存在多种方式， 所 以评估方法不同， 如在 WI-FI Direct作为 D2D技术时， 可以将直接传输速率与 S-UE的 UU口 使用的可用 RB下的传输速率来比较即可； 如果釆用 LTE技术下的 D2D, 由于釆用资源复用 的方式， 通过计算频谱效率的方式来比较。
具体实施时，初步判决步骤主要依据 UE上报的 UU口链路信道质量和 UD口链路信道质 量为 B-UE选择候选 S-UE。 具体的， 基站根据 B-UE的邻近 UE的 UU口链路信道质量（如大 尺度衰落和路径损耗的能力等级）和 UD口链路信道质量（如大尺度衰落和路径损耗的能力 等级）， 估算出该 B-UE的邻近 UE的 UU口链路的上下行信道质量； 基站根据 B-UE的邻近 UE 的 UD口信道质量信息（如链路大尺度衰落和路径损耗的能力等级）， 分析该 B-UE与其邻近 UE的 UD口链路的上下行信道质量； 基站根据以上确定出的 B-UE的邻近 UE的 UU口上下行 信道质量和 UD口链路信道质量，从这些邻近 UE中选择满足以下条件的邻近 UE作为该 B-UE 的候选 S-UE: UU口上下行信道质量不低于该 B-UE的 UU口链路信道质量， 并且 UD口链路 信道质量不低于该 B-UE的 UU口链路信道质量。 通过该步骤， 可选择出 UU口和 UD口的信 道质量均不低于 B-UE的 UU口信道质量的 S-UE, 即能够获得增益的 S-UE。
二次判决步骤主要依据 CQI信息进行判决。 具体的， 对于通过初步判决步骤得到的候 选 S-UE, 若候选 S-UE处于 Active (激活）状态， 则基站根据该候选 S-UE的 CQI和上行的测 量信息进一步判断预期增益是否超过一定门限， 若超过， 则将该候选 S-UE作为该 B-UE的 S-UE; 若候选 S-UE处于 Idle (空闲）状态， 则基站寻呼该候选 S-UE, 在该候选 S-UE接入系 统后， 根据该候选 S-UE的 CQI和上行的测量信息进一步判断预期增益是否超过一定门限， 若超过， 则将该候选 S-UE作为该 B-UE的 S-UE。
釆用两步判决法为 B-UE选择 S-UE, 可提升小区资源的频谱效率， 进而提升小区吞吐 量， 提升用户的服务速率， 进而提升用户 QoE ( Quality of Experience, 服务质量体验）。 另 外， 由于初始判决所依据的 UU口链路信道质量信息和 UD口链路信道质量信息， 可以从 UE 上报的邻近 UE列表中获得， 获取手段简单易行且系统开销较低； 选择出候选 S-UE集合后， 再根据 CQI对候选 S-UE集合中的候选 S-UE进行二次判决， 这样可以更准确的感知信道质 量。
上述二次判决步骤也可作为可选步骤，这样通过上述初步判决步骤选择出的候选 S-UE 即为该 B-UE的 S-UE。
釆用选择方式 3 , 可选择出 UU口和 UD口链路的信道质量均不低于 B-UE的 UU口链路信 道质量的 S-UE , 即通过选择出的 S-UE进行协同通信可获得较大增益。
以上几种选择方式仅为列举出的一部分优选实现方式， 基于上述原理为 B-UE选择 S-UE的其它实现方式也应包含在本发明的保护范围之内。
步骤 505: 基站在为该 B-UE确定协同通信的 S-UE后， 发起多用户协同通信流程， 包括 向参与多用户协同通信的 UE ( B-UE和该 B-UE的 S-UE )发送协同通信的配对请求。 具体实 现方式同前所述， 在此不再详述。
进一步的， 在步骤 505中， 协同通信的配对请求中还可以携带第二跳链路（即 UD口链 路）的测量配置信息等信息。 基站通过将第二跳链路的测量配置信息发送给 UE, 用来指示 UE对第二跳链路信道质量进行测量， 并在进行邻近 UE信息上报时携带 UD口链路信道质量 信息， 以使基站参考该信息为 B-UE确定 S-UE。
根据以上描述， 图 7A和图 7B分别示出了 UE与 eNB的信令交互流程。
图 7A所示的流程中， B-UE上报邻近 UE列表给 eNB , 该邻近 UE列表中包含邻近 UE的 UD口链路信道质量信息； eNB对于该邻近 UE列表中处于 Active状态的 UE , 根据该 UE上报 的测量报告获得该 UE的 UU口链路信道质量， 对于该邻近 UE列表中处于 Idle状态的 UE , 通 过寻呼该 UE使其进入 Active状态， 根据进入 Active状态后该 UE上报的测量报告获得该 UE 的 UU口链路信道质量； eNB根据获取到的 B-UE及其邻近 UE的 UU口链路信道质量和 UD口 链路信道质量进行多用户协同通信判决， 并在判决为触发多用户协同通信后， 向该 B-UE 以及该 B-UE的 S-UE发起协同通信配对请求， 该通信配对请求中携带 UD口链路测量配置信 息。
在图 7B所示的流程中， B-UE上报邻近 UE列表给 eNB, 且在上报的邻近 UE列表中携带 邻近 UE的 UU口链路信道质量信息和 UD口链路信道质量信息； eNB根据获取到的 B-UE及其 邻近 UE的 UU口链路信道质量和 UD口链路信道质量进行多用户协同通信判决，并在判决为 触发多用户协同通信后， 向该 B-UE以及该 B-UE的 S-UE发起协同通信配对请求， 该通信配 对请求中携带 UD口链路测量配置信息。
通过以上实施例二的描述可以看出，在实施例一的基础上， 网络设备为 B-UE选择协同 用户集时， 除了依据 UU口链路信道质量， 还依据 UD口链路信道质量， 从而进一步提高增 益， 进而提升用户的服务质量以及网络的整体性能。
需要说明的是， 以上主要以辅助信息中包含有 UD口链路信道质量信息为例描述的。如 果辅助信息中仅包含邻近 UE的 MUCC能力信息， 则基站可首先从 B-UE的邻居 UE集合中选 择出支持 S-UE能力的所有 UE作为候选 S-UE集合，然后从该候选 S-UE集合中选择 UU口链路 信道质量不低于该 B-UE的 UU口链路信道质量的候选 UE作为该 B-UE的 S-UE。 优选的， 可 按照 UU口链路信道质量从高到低的顺序， 从候选 S-UE集合中选择一个或多个（数量可预 先设定） UU口链路信道质量高于该 B-UE的 UU口链路信道质量的候选 UE作为该 B-UE的 S-UE。釆用该种方式选择出的 S-UE支持 S-UE能力，并且其 UU口链路信道质量不低于 B-UE 的 UU口链路信道质量。
其中， 基站可从 UE上报的邻近 UE列表中获得邻近 UE的 MUCC能力信息， 也可根据 B-UE的邻近 UE的标识， 从存储有 UE信息的服务器 （如近距离业务服务器）获得相应 UE 的 MUCC能力信息。
实施例三
本发明实施例三中， 结合以上各实施例所提供的由基站进行多用户协同通信触发判决 的方案， 针对某些 UE的应用需求， 可釆用 UE辅助基站进行触发判决。
具体的， 一方面， 基站按照上述各实施例提供的方式进行多用户协同通信触发判决； 另一方面， UE也进行多用户协同通信触发判决， 并在判定需要触发多用户协同通信时， 向 基站发送多用户协同通信触发请求。 当基站收到 UE发送的多用户协同通信触发请求后， 将 UE的多用户协同通信触发请求作为辅助信息， 结合 B-UE和其邻近 UE的信道质量等信息， 进一步确定是否触发多用户协同通信。 其中， 执行多用户协同通信触发判决的 UE可以是 B-UE, 也可以是具备 S-UE能力的 UE。
如果执行多用户协同通信触发判决的 UE是 B-UE, 则 B-UE可以根据当前的服务速率进 行触发判决， 具体为： 在当前的服务速率小于期望服务速率时判决需要触发多用户协同通 信， 目的在于提升用户的服务速率。 其中， 服务速率可以由 QoS中的 AMBR ( Aggregated Maximum Bit Rate, 聚合最大比特率）或 GBR ( Guaranteed Bit Rate, 保证比特率）表征， 期望服务速率可根据业务需要和系统性能等因素确定， 当前服务速率可通过对基站调度用 户的速率进行统计得到。 进一步的， B-UE发送多用户协同通信触发请求时， 可将该 B-UE 确定出的候选 S-UE的信息携带于该请求发送给基站。
如果执行多用户协同通信触发判决的 UE是具备 S-UE能力的 UE, 则该 UE作为特殊的 UE (如超级 E5, 其主要功能是用于为其它 UE提供支撑服务）， 通过近距离发现技术检测到 B-UE后， 在发现与该 B-UE的第二跳链路 ( UD口链路）达到预期增益门限时， 向基站发送 多用户协同通信触发请求。 进一步的， 该 UE发送多用户协同通信触发请求时， 可将该 UE 确定出的 B-UE的候选 S-UE的信息携带于该请求发送给基站。
基站在接收到 UE发送的多用户协同通信触发请求后， 获取其中携带的 B-UE信息， 按 照前述实施例的方式对是否针对该 B-UE触发多用户协同通信进行判决。如果判定为无需对 该 UE触发多用户协同通信， 则丢弃该多用户协同通信触发请求， 并可进一步向发起请求的 UE返回响应； 如果判定为需要对该 UE触发多用户协同通信， 则可进一步按照前述实施例 的方式为该 UE选择 S-UE, 或者在前述实施例提供的选择 S-UE的方式的基础上， 将 UE在多 用户协同通信触发请求中携带的候选 S-UE作为辅助信息， 为 B-UE选择 S-UE。
