具体实施方式 下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案 进行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实 施例， 而不是全部的实施例。 本发明的实施例提供一种待支撑终端的建立协作通信的方法， 参照 图 1 所示， 其中待支撑终端指有支撑功能的终端， 当待支撑终端能够满 足协作通信的条件时， 便可以作为支撑终端进行协作通信， 该方法包括 以下步骤：
1 01、 处于空闲状态下的待支撑终端接收基站发送的系统广播。 系统广播用于通知空闲待支撑终端用作待支撑终端， 并指示待支撑 终端获取待支撑终端与基站之间的信道质量参数。
1 02、待支撑终端根据系统广播中获取支撑终端与基站之间的信道质 量参数 其中， 信道质量参数代表两个通信设备之间的通信质量， 具体可以 是两个通信设备之间的路损等级或参考信号接收功率， 在这里需要获得 的是待支撑终端与基站之间的信道质量参数。 具体的， 待支撑终端接收基站发送的下行导频信号， 并在下行导频 信号中获取参考信号接收功率。 或者， 接收基站发送的下行导频信号， 及系统广播， 在下行导频信 号中获取参考信号接收功率， 并在系统广播中获取基站的发射功率。 根 据参考信号接收功率和基站的发射功率计算路损等级。 其中， 路损值等于发射功率减去参考信号接收功率； 或者， 也在可 以得到基站的天线增益时， 可以获得更精确的路损， 这时路损值等于基 站发射功率减去基站天线增益再减去参考信号接收功率。
Figure imgf000015_0001
表 1 举例说明 , 参照表 1所示， 从路损值为 77db ( db代表分贝， 是路损 单位） 开始计算路损等级， 路损值每升高 6db 路损等级升高一级， 等级 越高代表通信质量越差； 将得到的路损值与表 1 中的路损等级对应， 从 而得到相应的路损等级； 其中， 当一个终端的路损等级小于 77 db时， 证 明其通信质量足够好， 则不能作为受益终端； 当一个终端的路损等级小 于 7 7db时， 且当协作的终端之间使用的频率为基站与终端进行通信的系 统频率时 （例如， 协作的终端通信时使用的频率为终端与基站进行通信 的 LTE系统的上行频率时） ， 若其作为支撑终端， 由于与基站过于接近， 会对基站信号造成干扰， 则不能作为支撑终端；
1 03、 当待支撑终端与基站之间的信道质量参数满足第一阈值时， 获 取受益终端与待支撑终端之间的信道质量参数。 其中， 第一阈值是用于判断待支撑终端与基站之间的信道质量是否 良好， 该信道质量参数为待支撑终端与基站之间的路损等级或待支撑终 端与基站之间的参考信号接收功率。 其中， 第一阈值中预定的阈值由基站设定， 并由基站发送给待支撑 终端； 或者， 在受益终端与基站之间的信道质量参数变化緩慢时， 将该受 益终端与基站之间的信道质量参数作为预定的阈值， 得到第一阈值， 并 由基站转发给待支撑终端。 或者， 第一阈值在标准协议文本中规定： 比如支撑终端与基站的信 道质量门限为： a 乘以基站的最大发射功率， a 取值一般为 0. 8 , 0. 7， ... ...， 0. 4 ; 这样待支撑终端可以根据标准协议自行预定阈值。 具体的， 当信道质量参数为路损等级（路损等级越高， 路损值越大， 信道质量就越差） 时， 该待支撑终端与基站之间的路损等级要小于预定 的阈值， 这样说明该待支撑终端与基站之间的信道质量良好。 接着， 该 待支撑终端与基站之间的路损等级要小于受益终端与基站之间的路损等 级， 这样说明该待支撑终端比该受益终端的信道质量要好， 能够为该受 益终端提供协作支撑。 可选的， 当信道质量为参考信号接收功率时， 该待支撑终端与基站 之间的参考信号接收功率要大于预定的阈值， 这样说明该待支撑终端与 基站之间的信道质量良好。 接着， 该待支撑终端与基站之间的参考信号 接收功率要大于受益终端与基站之间的参考信号接收功率， 这样说明该 待支撑终端比该受益终端的信道质量要好， 能够为该受益终端提供协作 支撑。 当协作的终端之间使用的频率为基站与终端进行通信的系统频率时
(例如， 协作的终端通信时使用的频率为终端与基站进行通信的 LTE 系 统的上行频率时） ， 如果该待支撑终端与基站之间的信道质量超过预定 的最大阈值时， 则不能选取该待支撑终端作为支撑终端， 因为这种情况 下， 该待支撑终端与基站过于接近， 会对基站信号造成干扰， 则不能作 为支撑终端；
104、 当待支撑终端与受益终端之间的信道质量参数满足第二阔值 时， 待支撑终端生成测量事件， 并将测量事件发送给基站。 以便所述基站根据所述测量事件向所述待支撑终端发送支撑协作指 示。 其中， 第二阈值用于判断待支撑终端与受益终端之间的信道质量是 否良好， 第二阈值可以从基站的广播消息中获取， 也可以是终端自行建 立的判断条件。 可以根据待支撑终端与受益终端之间的路损等级或待支 撑终端与受益终端之间的参考信号接收功率进行判断。 具体的， 当信道质量参数为路损等级时， 该待支撑终端与受益终端 之间的路损等级要小于预定的阈值， 这样说明该待支撑终端与受益终端 之间的信道质量良好， 能够为该受益终端提供协作支撑。 可选的， 当信道质量为参考信号接收功率时， 该待支撑终端与受益 终端之间的参考信号接收功率要大于预定的阈值， 这样说明该待支撑终 端与受益终端之间的信道质量良好， 能够为该受益终端提供协作支撑。 其中， 测量事件包括： 测量事件的 ID、 测量事件的内容、 待支撑终 端与基站之间的信道质量参数、 待支撑终端与受益终端之间的信道质量 参数及受益终端的标识。 其中， 测量事件的内容包括两次判断事件的内 容， 分别是待支撑终端与基站之间的信道质量参数满足第一阈值； 待支 撑终端与受益终端之间的信道质量参数满足第二阈值。 当待支撑终端满足第二阈值时， 则认定自己为备选支撑终端， 生成 测量事件， 然后与基站发起无线连接， 测量事件在无线建立之后按照 LTE 的流程上报给基站； 或者， 测量事件的上报也可以这样实现： 在无线建 立请求中有一个比特指示备选支撑终端测量事件上报， 然后在基站的后 续查询消息的应答中上报； 或者， 测量事件还可以在无线建立过程中的 消息中携带。 具体的， 待支撑终端向基站发送测量事件的过程： 待支撑终端的测量模块生成测量事件 D1事件之后， 测量模块给 RRC ( Rad i o Re s our ce Con t r o l , 无线资源控制） 模块发送指示： 发起 RRC 链接建立请求， 请求消息中携带测量事件 D 1和建立 RRC链接的原因。 所 述建立 RRC链接的原因为： 待支撑终端发起。 或者， 待支撑终端的测量模块生成测量事件之后， 测量模块给 RRC 模块发送指示： 发起 RRC链接建立请求， 请求消息中携带建立 RRC链接 的原因。 所述建立 RRC链接的原因为： 待支撑终端的 D1事件生成。 然后 在基站的后续查询消息的应答中上报测量事件 D 1。 或者待支撑终端的 RRC模块根据底层的测量结果判断比较后生成了 测量事件 D1 , 该测量事件 D 1 的生成激发 RRC模块生成 RRC链接建立请 求消息， 请求消息中携带测量事件 D1和建立 RRC链接的原因。 所述建立 RRC链接的原因为： 待支撑终端发起。 或者待支撑终端的 RRC模块根据底层的测量结果判断比较后生成了 测量事件 Dl， 该测量事件 D 1 的生成激发 RRC模块生成 RRC链接建立请 求消息， 请求消息中携带建立 RRC链接的原因。 所述建立 RRC链接的原 因为： 待支撑终端的 D1事件生成。 然后在基站的后续查询消息的应答中 上报测量事件 Dl。 基站从 RRC链接建立请求中得到测量事件 D 1 和建立 RRC链接的原 因； 或者基站从 RRC链接建立请求中得到建立 RRC链接的原因， 然后在 基站的后续查询消息的应答中获取测量事件 D 1。
1 05、 待支撑终端接收基站发送的支撑协作指示， 并根据支撑协作指 示与受益终端建立协作通信集。 上述实施例中， 空闲待支撑终端接收基站发送的系统广播， 并根据 系统广播获取待支撑终端与基站之间的信道质量参数， 当待支撑终端与 所述基站之间的信道质量参数满足第一阈值时， 获取所述受益终端与所 述待支撑终端之间的信道质量参数； 当所述待支撑终端与所述受益终端 之间的信道质量参数满足第二阁值， 待支撑终端生成测量事件， 并将测 量事件发送给基站， 以便基站根据所述测量事件向待支撑终端发送支撑 协作指示； 接收基站发送的支撑协作指示， 并根据支撑协作指示与受益 终端建立协作通信集。 这样避免了所有的待支撑终端与基站进入连接状 态来判断是否有能力作为支撑终端， 降低了功耗。 进一步的， 本发明实施例提供一种基站建立协作通信的方法， 参照 图 2所示， 包括以下步驟：
201、 基站向空闲的待支撑终端发送系统广播。 其中， 系统广播用于通知空闲待支撑终端用作待支撑终端， 并指示 待支撑终端获取待支撑终端与基站之间的信道质量参数。 该系统广播至少包括， 指示比特和第一阈值中的一项； 当系统广播只包括指示比特时， 指示比特指示空闲待支撑终端用作 待支撑终端， 并指示待支撑终端获取待支撑终端与基站之间的信道质量
当系统广播只包括第一阈值时， 空闲待支撑终端根据第一阈值触发 待支撑指令， 该空闲待支撑终端根据该待支撑指令用作待支撑终端并获 取待支撑终端与基站之间的信道质量参数； 当然， 基站发送的系统广播也可以同时包括指示比特和第一阈值。
202、 基站接收待支撑终端设备发送的测量事件。 其中， 测量事件包括： 测量事件的 ID ( Ident i ty, 身份标识） 、 测 量事件的内容、 待支撑终端与基站之间的信道质量参数、 待支撑终端与 受益终端之间的信道质量参数及受益终端的标识， 以便基站根据测量事 件发送协作通信指示。 受益终端的标识包括受益终端与支撑终端之间的信标信号的 index、 D2Dcode ( Dev i ce t o Dev i ce Code , 设备到设备的标识） 、 频带的 I D中 的至少一个， 其中设备到设备的标识 D2Dcode 是用于发现功能使用的一 种终端设备标识， 该标识是核心网分配的。
203、 基站根据测量事件向待支撑终端发送支撑协作指示。 其中， 支撑协作指示用于通知待支撑装置与受益终端建立协作通信 集， 从而使待支撑终端成为支撑终端。
204、 基站根据测量事件向受益终端发送受益协作指示。 其中， 受益协作指示用于通知受益终端与待支撑终端建立协作通信 集， 协作指示中至少会包含协作资源参数。 上述实施例是基站进行协作通信的方法， 基站向空闲的待支撑终端 发送系统广播， 通知空闲的待支撑终端用作该受益终端的待支撑终端， 并指示待支撑终端获取信道质量参数， 待支撑终端根据该信道质量参数 进行判断， 若满足条件， 向基站发送测量事件， 基站根据测量事件通知 待支撑终端与受益终端建立协作通信集； 这样避免了所有的待支撑终端 与基站进入连接状态来判断是否有能力作为支撑终端， 降低了功耗。 通 过系统广播通知空闲的待支撑终端用作受益终端的待支撑终端， 系统广 播可以覆盖基站系统中的允许范围内的所有终端， 提高了待支撑终端的 可选数量。 可选的，参照图 3所示， 本发明实施例提供一种协作通信的方法（当 然附图中只给出了个步骤中的关键特征， 具体以实施例的描述为准） 包 括以下步骤：
301、 基站对所有终端进行传输速率检测， 根据检查结果在所有终端 中选取受益终端。
302、 基站向受益终端发送信标信号信息表。 其中， 参照表 2所示， 信标信号信息表是指信标信号序列号与信道 质量参数等级相对应的关系表。 每个信标信号具有对应的序列号， 信道 质量参数会根据他们的数值划分为若千等级。 每个信标信号会对应一个 信道质量等级。 信标信号信息表中就是将信标信号的序列号与信道质量 等级相对应的一个表。

表 1
303、 受益终端获取受益终端与基站之间的信道质量参数。 其中， 受益终端获取受益终端与基站之间的信道质量参数， 其方法 与步驟 302 待支撑终端的获取待支撑终端与基站之间的信道质量参数方 法相同， 这里就不再赘述。
304、受益终端根据受益终端与基站之间的信道质量参数在信标信号 信息表中选取信标信号。
305、 受益终端将选择的信标信号发送至待支撑终端。 具体的， 参照表 2 所示， 其中， 信标信号信息表是指信标信号序列 号与信道质量参数等级相对应的关系表。 这个表 2 能够使受益终端根据 该受益终端与基站之间的信道质量参数， 选择对应的信标信号进行发送。 例如， 受益终端与基站之间的信道质量参数等级为 2 , 即可以选择 2号信 标信号或 1 2号信标信号进行发送。 其中， 该信标信号信息表也可以包括信标信号的发送功率和发送时 间， 受益终端按照发送功率和发送时间向待支撑终端发送信标信号。 当 信标信号信息表中不包含发送时间的时候， 则受益终端一直周期性的发 送信标信号， 该发送周期可能是基站通知给受益终端的， 或者是受益终 端自己选择的。 当信标信号信息表中不包含发送功率的时候， 受益终端 可以使用自己的最大发射功率， 或者受益终端使用自己向基站发送数据 时的发送功率， 数据长度为一个特定值 （例如： 数据块长度 TB s i ze 为 72b i t ) , 调制方式与编码速率是基站配置。 例如， 上述信标信号可以是 ZC序列， 一共可以分为 48组， 每组最 多 1 6个。 在同一个通信区域内可能存在多个通信协作集， 由于每一组使 用同样一个种子 ZC序列生成的信标信号，这样可以区分这些通信协作集。
306、 基站向待支撑终端发送系统广播。 该系统广播在步骤 201 中详细描述， 这里就不再赘述。
307、 处于空闲状态下的待支撑终端接收基站发送的系统广播。 其中， 系统广播用于通知空闲待支撑终端用作待支撑终端， 并指示 待支撑终端获取待支撑终端与基站之间的信道质量参数。
308、待支撑终端根据系统广播的指示获取支撑终端与基站之间的信 道质量参数。
309、 当待支撑终端与基站之间的信道质量参数满足第一阈值时， 待 支撑终端接收受益终端发送的信标信号， 并通过信标信号获取受益终端 与待支撑终端之间的信道质量参数。 其中， 在步骤 303后已经说明了具体的判断方法， 这里就不再赘述。 若待支撑终端与基站之间的信道质量参数满足第一阈值， 则继续进行建 立协作通信； 若待支撑终端与基站之间的信道质量参数不满足第一阈值， 则该待支撑终端中断建立协作通信。 其中， 满足第一阈值的待支撑终端可以通过搜索该基站下的发现资 源配置或者全部频带或者受益终端专用的资源来监测信标信号， 并接收 该信标信号。 其中， 受益终端与待支撑终端之间信道质量参数为路损等级或者参 考信号接收功率。 待支撑终端接收信标信号， 并根据信标信号表查询信 标信号的信道质量参数。 其中， 待支撑终端可以从基站的系统广播消息中获取信标信号表， 或者信标信号中携带该信标信号表。 31 0、 当待支撑终端与受益终端之间的信道质量参数满足第二阈值 时， 待支撑终端生成测量事件。 其中， 在步骤 305后已经说明了具体的判断方法， 这里就不再赘述。 若待支撑终端与受益终端之间的信道质量参数满足第二阈值， 则继续进 行建立协作通信； 若待支撑终端与受益终端之间的信道质量参数不满足 第二阈值， 该待支撑终端中断建立协作通信。
31 1、 待支撑终端将测量事件发送给基站。 其中， 测量事件的具体上报过程在步骤 306后有具体的描述， 这里 就不在赘述。 其中， 测量事件包括： 测量事件的身份标识 I D、 测量事件的内容、 待支撑终端与基站之间的信道质量参数、 待支撑终端与受益终端之间的 信道质量参数及受益终端的标识。 其中， 测量事件的内容包括两次判断 事件的内容， 分别是待支撑终端与基站之间的信道质量参数满足第一阈 值； 待支撑终端与受益终端之间的信道质量参数满足第二阈值。
312、 基站根据测量事件向备选支撑终端发送支撑协作指示。 支撑协作指示用于通知待支撑装置与受益终端建立协作通信集， 从 而使待支撑终端成为支撑终端。
31 3、 基站根据测量事件向受益终端发送受益协作指示。 受益协作指示用于通知受益终端与待支撑终端建立协作通信集。
314、 待支撑终端接收基站发送的支撑协作指示， 并根据支撑协作指 示与受益终端建立协作通信集， 从而成为支撑终端。
315、 受益终端接收基站发送的受益协作指示， 并根据受益协作指示 与待支撑终端建立协作通信集。 其中， 上述实施例只描述了一个受益终端与一个待支撑终端建立协 作通信的过程， 当然也可以根据实施例的方法， 将其它的受益终端或多 个满足预设条件待支撑终端加入协作通信集， 从而形成多个支撑终端对 单个受益终端、 单个支撑终端对多个受益终端及多个支撑终端对多个受 益终端的协作通信方式。 上述实施例中， 基站向空闲待支撑终端发送系统广播， 通知空闲待 支撑终端用作待支撑终端， 并指示待支撑终端获取待支撑终端与基站之 间的信道质量参数， 待支撑终端根据待支撑终端与基站之间的信道质量 参数进行判断， 若满足条件， 进一步判断待支撑终端与受益终端之间的 信道质量参数， 若满足条件， 向基站发送测量事件， 基站根据测量事件 通知待支撑终端与受益终端建立协作通信集； 这样避免了所有的待支撑 终端与基站进入连接状态来判断是否有能力作为支撑终端， 降低了功耗。 参照图 4 所示， 本发明实施例提供一种建立协作通信的待支撑终端 4 00 , 其中待支撑终端 400指有支撑能力的终端， 当待支撑终端 400能够 满足协作通信的条件时， 可以作为支撑终端对协作通信集进行支撑， 该 待支撑终端 400包括： 接收单元 401 , 在待支撑终端空闲的状态下， 用于接收基站发送的 系统广播。 系统广播用于通知空闲待支撑终端用作待支撑终端， 并指示待支撑 终端获取待支撑终端与基站之间的信道质量参数。 获取单元 402， 用于根据接收单元 401 接收到的系统广播获取支撑 终端与基站之间的信道质量参数。 其中， 信道质量参数代表两个通信设备之间的通信质量， 具体可以 是两个通信设备之间的路损等级或参考信号接收功率， 在这里需要获得 的是待支撑终端与基站之间的信道质量参数。 具体的， 待支撑终端接收基站发送的下行导频信号， 并在下行导频 信号中获取参考信号接收功率。 或者， 接收基站发送的下行导频信号， 及系统广播， 在下行导频信 号中获取参考信号接收功率， 并在系统广播中获取基站的发射功率。 根 据参考信号接收功率和基站的发射功率计算路损等级。 其中， 路损值等于发射功率减去参考信号接收功率； 或者， 也在可 以得到基站的天线增益时， 可以获得更精确的路损， 这时路损值等于基 站发射功率减去基站天线增益再减去参考信号接收功率。 获取单元 402， 还用于当第一判断单元 403 的判断结果满足第一阈 值时， 获取受益终端与待支撑终端之间的信道质量参数。 其中， 第一阈值中预定的阐值由基站设定， 并由基站发送给待支撑 终端； 或者， 在受益终端与基站之间的信道质量参数变化緩慢时， 将该受 益终端与基站之间的信道质量参数作为预定的阔值， 得到第一阐值， 并 由基站转发给待支撑终端。 或者， 第一阈值在标准协议文本中规定： 比如支撑终端与基站的信 道质量门限为： a 乘以基站的最大发射功率， a 取值一般为 0. 8， 0. 7 , ... ... , 0. 4 ; 这样待支撑终端可以根据标准协议自行预定阔值。 其中， 若待支撑终端与基站之间的信道质量参数满足第一阈值， 则 继续进行建立协作通信； 若待支撑终端与基站之间的信道质量参数不满 足第一阈值，
