RSCP)、 或者码片功率谱密度（CPICH Ec/No)、 或者路径损耗（CPICH PathLoss)等。 如果 UE检测 /获知某小区的多于一种形式的小区质量， 则 UE可以在其中全部或部分形式 的小区质量满足 lk准则时， 上报测量报告。 该实施例中的 lk准则还可以视为一种 RNC更新 CoMP发送集的准则， 即 lk准则被满 足将触发 UE上报测量报告， 该测量报告触发 R C判决该 UE的 CoMP发送集是否需要更 新， 和 /或如何更新该 UE的 CoMP发送集。例如， RNC判决该 UE的 CoMP发送集是否需要 更新可以包括： 当 UE当前业务的 QoS要求达到预设要求时， 或者满足 lk准则的小区的小 区质量达到预设门限时， RNC确定需要更新 CoMP发送集。又如， 当 UE支持 CoMP模式， 满足 lk准则的小区也具备支持 CoMP模式的能力时， 则 RNC确定需要更新 CoMP发送集。 本实施例中， RNC更新 UE的 CoMP发送集可以包括多种情况。 例如， RNC向该 UE 当前的 CoMP发送集添加小区，或者 R C向该 UE当前的 CoMP发送集中添加小区的同时， 从该 UE当前的 CoMP发送集删除质量较差的小区。 上述 CoMP发送集的更新方法能够实 现对 CoMP协同小区的灵活调整，有利于进一步提高小区整体性能及小区边缘用户性能。 可选的， RNC确定需要更新自身保存的该 UE的 CoMP发送集之后， 通过发送更新后的 CoMP发送集或者与更新后的 CoMP发送集对应的 CoMP配置，实现对 NodeB禾口 /或 UE应用 的 CoMP发送集的更新。 又如， RNC为 NodeB和 UE对该 UE的 CoMP进行了预配置，该 CoMP配置对应的 CoMP 协作集包括一个或多个能够作为协同小区的小区， 上述小区对应的 CoMP配置没有被激 活， 即当前没有作为协同小区向该 UE发送数据， 则 RNC可以通知 NodeB激活该 UE的 CoMP协作集中一个或多个小区对应的 CoMP配置， 使激活 CoMP配置的小区作为协同小 区向该 UE发送数据， 也即激活 CoMP配置的小区被添加到该 UE的 CoMP发送集中， 实现 了对该 UE的 CoMP发送集的更新。 可选的， RNC通知 NodeB去激活该 UE的 CoMP发送集 中一个或多个小区对应的 CoMP配置，使去激活 CoMP配置的小区不再作为协同小区向该 UE发送数据， 也即去激活 CoMP配置的小区从该 UE的 CoMP发送集中删除， 实现了对该 UE的 CoMP发送集的更新。上述 CoMP发送集的更新方法能够实现对 CoMP协同小区的灵 活调整， 并降低终端耗电量。 如图 1所示，本发明实施例提供一种更新 CoMP发送集的方法。该实施例可以包括如 下步骤：
S110、 RNC在审计过程中获取 NodeB的 CoMP能力信息。 例如， RNC发送审计请求消息 Audit request给 NodeB ( Sl lOa) ， 并接收 NodeB发送 的审计响应消息 Audit Response ( SI 10b) ， 该审计响应消息携带 NodeB的 CoMP能力信 息。 其中， NodeB的 CoMP能力信息可以包括 NodeB是否支持 CoMP模式的指示， 例如： lbit的指示位为 0， 表示 NodeB不支持 CoMP模式。 当 NodeB支持 CoMP模式， 例如指示位为 1时， NodeB的 CoMP能力信息还包括 UE所 属 NodeB本地小区的协同小区的小区标识或小区索引， 以使 RNC获知该 NodeB的本地小 区可以与哪些小区进行协同。
S120、 RNC获取 UE的 CoMP能力信息。 例如， RNC接收 UE发送的 UE能力信息 UE CAPABILITY INFORMATION, 该 UE能 力信息包括 UE的 CoMP能力信息。 其中， UE的 CoMP能力信息可以包括 UE是否支持 CoMP模式的指示， 例如： lbit的 指示位为 1， 表示 UE支持 CoMP模式。
S130、 RNC发送测量控制消息 MEASUREMENT CONTROL给 UE，该测量控制消息 包括 lk准则。 可选的， lk准则包括以下任一项 UE发送测量报告的条件（可简称 lk事件） ， 例如：
( 1 )属于 UE的激活集且不属于 UE的 CoMP发送集的小区的小区质量大于 UE的 CoMP发送集中任一个小区。
(2)属于 UE的激活集且不属于 UE的 CoMP发送集的小区的小区质量大于 UE的 CoMP发送集中信号质量最差的小区。
( 3 )属于 UE的激活集且不属于 UE的 CoMP发送集的小区的小区质量大于 UE的 CoMP发送集中至少两个小区的小区质量平均值。 (4)属于 UE的激活集且不属于 UE的 CoMP发送集的小区的小区质量大于 UE的
CoMP发送集中至少两个小区的小区质量加权平均值。 本发明其他实施例提供的 lk准则也适用于本实施例， 此处不再赘述。 可选的， 用于通知 UE执行测量 （如同频测量） 的测量控制消息还包括时间信息， 该时间信息用于指示 UE在发送测量报告之前， lk准则被满足的时长， 也即在 lk准则被 持续满足多长时间之后 UE才能发送测量报告。
S140、 在 lk准则被满足时， UE发送测量报告给 R C。 可选的， 如果 UE接收到了上述时间信息， 则 UE测量到存在满足 lk准则的小区并持 续如上述时间信息所示的时长后， 发送测量报告。
UE发送的测量报告可以包括满足 lk准则的所有小区或部分小区的小区质量， 以及 上述小区的小区标识或小区索引。 可选的， 该测量报告还包括： 该 UE当前的 CoMP发送集中至少一个小区的小区质量 和小区标识 （或者小区索引） ， 该小区的小区质量小于满足 lk准则的小区的小区质量。 这样， RNC可以根据该 UE上报的测量结果刪除该 UE当前的 CoMP发送集中质量比较差 的小区。
S150、 RNC接收测量报告， 并更新该 UE的 CoMP发送集。 可选的， R C先根据小区的能力、 业务的 QoS要求、 小区的小区质量、 发送集中的 小区数量或数量上限等一个或多个因素确定是否需要更新该 UE的 CoMP发送集， 如果 是， 则进行更新自身保存的该 UE的 CoMP发送集。 例如， 满足 lk准则的小区具备支持 CoMP模式的能力， 或者 UE当前业务的 QoS要求 达到预设要求， 或者满足 lk准则的小区的小区质量达到预设门限， 则 R C将该小区加入 CoMP发送集。 又如， RNC对 CoMP发送集有数量上限， 则 RNC判断当前的 CoMP发送集中的小区 数量是否达到小区数量上限， 如果否， 则将满足 lk准则的小区加入 CoMP发送集， 并使 更新后的 CoMP发送集中的小区数量不超过小区数量上限。 如果该 UE当前的 CoMP发送 集中的小区数量已达到小区数量上限， 则 RNC可以删除 CoMP发送集中的部分小区， 例 如小区质量较差的小区， 并将满足 lk准则的小区加入 CoMP发送集。 又如， RNC通过测量报告还获知该 UE的 CoMP发送集中哪些小区的小区质量较差， 则 RNC可以将该小区从 CoMP发送集中删除所有或部分质量较差的小区。 如果 R C将某小区从该 UE的 CoMP发送集中刪除，则 RNC还可以进一步将该小区从 该 UE的 CoMP协作集和 /或激活集中删除。 S160、 RNC与 NodeB协商更新后的 CoMP发送集对应的 CoMP配置 （即新 CoMP配 置） 。 例如， R C在 S150中确定将某小区添加到该 UE的 CoMP发送集中时（可能尚未更新 自身保存的该 UE的 CoMP发送集） ， 可以和 NodeB通过无线链路建立过程、 或者无线链 路重配过程、或者无线链路增加过程协商与更新后的 CoMP发送集对应的 CoMP配置。比 如， R C确定更新 CoMP发送集时， 如图 1中的 S160a-160b所示， 通过无线链路增加请 求消息向 NodeB请求分配 CoMP配置对应的资源， NodeB在无线链路增加响应消息中反馈 分配的与 CoMP配置对应的资源。 S170、 RNC将更新后的 CoMP发送集对应的 CoMP配置 （即新 CoMP配置）发送给
UE。 例如， RNC发送激活集更新消息或无线承载重配置消息时， 将新 CoMP配置发送给 UE。 UE根据接收到的 CoMP配置更新 UE的 CoMP发送集。 例如， 将 CoMP配置涉及的全 部或部分小区加入 UE当前的 CoMP发送集或 UE新建的 CoMP发送集中。 可选的， 上述新 CoMP配置包括更新后的 CoMP发送集中所有小区对应的 CoMP配 置， 或者， CoMP发送集的更新所涉及的小区对应的 CoMP配置。 本实施例中的 S110和 S120为可选步骤，两者没有必然的顺序关系。 R C获取 NodeB 的 CoMP能力信息和 UE的 CoMP能力信息的过程也不限于上述举例， 例如， R C可以接 收无线资源控制（Radio Resource Control, RRC)连接建立完成消息或者 UE能力信息消 息，并从中获取 UE的 CoMP能力信息。本实施例中的 S160和 S170也没有必然的顺序关系。 本实施例中， NodeB在接收到新 CoMP配置后， 将更新该 UE的发送集， 更新后的发 送集中的协同小区将协同向该 UE发送数据。 UE在接收到新 CoMP配置后，将接收各协同 小区发送的数据。 这种 CoMP协同小区的灵活调整， 有利于进一歩提高小区整体性能及 小区边缘用户性能。 如图 2所示，本发明的另一实施例提供一种 CoMP发送集的更新方法。该实施例可以 包括如下步骤。

S420、 在 lk准则被满足时， UE发送测量报告给 R C。 本实施例中 S410-420与本发明其他实施例中的 S 130-S 140类似， 并且本发明其他实 施例中的 S110-120可以结合至本实施例的 S410之前， 此处不再赘述。 S430、 RNC接收测量报告， 并通知 NodeB激活该 UE的预设的 CoMP配置中全部或部 分协同小区的 CoMP配置。 可选的， R C根据小区的小区质量、 或业务量等因素确定是否激活预设的 CoMP配 置， 如果是， 则通知 NodeB激活该 UE的预设的 CoMP配置中至少一个满足 lk准则的小区 的 CoMP配置。 例如， 一个满足 lk准则的小区的小区质量不低于预设门限， 且当前业务 量高于预设要求， 则 RNC通知 NodeB激活该小区的 CoMP配置。
S440、 NodeB发送高速共享控制信道命令（HS-SCCH order)消息，该 HS-SCCH order 消息用于激活该 UE的预设的 CoMP配置中全部或部分协同小区的 CoMP配置。 例如， HS-SCCH order消息包括用于激活 CoMP配置的激活指示。可选的， HS-SCCH order消息还包括协同小区的小区标识或索弓 I指示，该协同小区为激活指示对应的激活目 标小区。 HS-SCCH order消息未包括激活指示对应的激活目标小区的相关信息， 则默认 激活预设的 CoMP配置中的所有小区的 CoMP配置，即：将预设的 CoMP配置对应的 CoMP 协作集中的所有小区都加入到该 UE的 CoMP发送集中， 使这些小区都参与多点发射。 其中， NodeB可以通过 UE的服务小区、 和 /或 UE的服务小区的协同小区向 UE发送 HS-SCCH order消息。 可选的， 本实施例的 S440中， NodeB也可以发送包括激活指示的其他层一消息或层 二消息， 而不限于举例的 HS-SCCH order消息。 本实施例能够实现 RNC确定激活哪些小区的 CoMP配置， 从而避免终端一直监测所 有协同小区的下行信道， 降低终端电耗。 本发明的另一实施例提供一种 CoMP发送集的更新方法， 该方法中， 当某小区满足 添加到激活集的条件时， R C将该小区添加到激活集中， 同时为 UE和 NodeB对该 UE的 CoMP进行预配置（如图 S500) ， 使 UE和 NodeB、 RNC保存的预设的 CoMP预配置一致， 该预设的 CoMP配置对应的 CoMP协作集包括具备参与同时向该 UE发送数据的能力的小 区， 还可以包括该 UE的下行 HSDPA配置， 上行 HSUPA配置信息等。 该实施例包括如下 步骤。
S510、 NodeB确定需要激活该 UE的预设的 CoMP配置中哪个或哪些小区的 CoMP配 置。 例如， NodeB可以在 UE的业务量高于预设门限时， 确定需要激活的 CoMP配置并确 定激活哪个或哪些小区的 CoMP配置。
S520、 NodeB发送 HS-SCCH order消息给 UE， HS-SCCH order消息包括用于激活 CoMP配置的激活指示。 其中， NodeB可以通过 UE的服务小区、 禾口 /或 UE的服务小区的协同小区向 UE发送 HS-SCCH order消息。 可选的， HS-SCCH order消息还包括协同小区的小区标识或索引指示， 该协同小区 为激活指示对应的激活目标小区。 HS-SCCH order消息未包括激活指示对应的激活目标 小区的相关信息， 则默认激活预设的 CoMP配置中的所有小区的 CoMP配置， 即： 预设的 CoMP配置对应的 CoMP协作集中的所有小区都加入到该 UE的 CoMP发送集中，使这些小 区都参与多点发射。
如图 6a所示的 HS-SCCH order消息， 其中的 Coordinated cell activation (协同小区激 活） 信息用于指示是否激活 CoMP配置。 该 HS-SCCH order消息中的 order字段可以包括 Coordinated cell activation信息， 该消息还可以包括指示 order (命令） 类型的 order type 信息和 UE标识 （UE identity) 。 例如， 为 1的 Coordinated cell activation信息即为激活指 示。上述 order字段还可以包括 Secondary uplink frequency activation (辅助上行频率激活） 信息和 Secondary serving HS-DSCH cell activation (辅助服务 HS-DSCH小区激活）信息。 如图 6b所示的 HS-SCCH order消息，其中的 order信息用于指示是否激活 CoMP配置， 例如，为 1的该信息即为激活指示。该消息中的 cell identity包括激活目标小区的小区标识 或小区索弓 I。如果通过 UE的服务小区发送 HS-SCCH order消息，则默认激活预设的 CoMP 配置中的所有小区的 CoMP配置，该消息中的 cell identity可为空或省略，以减少 HS-SCCH order消息内容。 该 HS-SCCH order消息还可以包括指示 order (命令）类型的 order type信 息和 UE标识 （UE identity) 。 本实施例能够实现 NodeB确定激活哪个或哪些小区的 CoMP配置， 从而避免终端一 直监测所有协同小区的下行信道， 降低终端电耗。 上述实施例以 HS-SCCH order消息为例进行说明，但上述实施例中激活指示和 /或去 激活指示并不局限于由该 HS-SCCH order消息携带， NodeB也可以发送包括激活指示和 / 或去激活指示的其他消息， 例如其他层一消息或层二消息， 此处不再赘述。 本实施例中的 HS-SCCH order消息还可以用于指示去激活 CoMP配置。 例如， 如图
6a所示的 HS-SCCH order消息中， Coordinated cell activation信息为 0时， 该信息即为去激 活指示。如图 6b所示的 HS-SCCH order消息中的 order信息为 0的时，该信息即为去激活指 示。 例如， 用于指示去激活 CoMP配置的 HS-SCCH order消息适用于以下场景： NodeB 在 UE的当前业务量低于预设门限或者 UE在某个协同小区反馈的 CQI低于预设要求时， 确定去激活某个协同小区的 CoMP配置， 或者去激活所有的协同小区的 CoMP配置。 UE 接收到 HS-SCCH order时， 停止在该协同小区接收下行数据。 通过上述方法， NodeB可 以确定去激活预设的 CoMP配置或当前的 CoMP中全部或部分协同小区的 CoMP配置， 从 而避免终端一直监测所有协同小区的下行信道， 降低终端电耗。 本发明各实施例适用于能够采用 CoMP技术的各种系统， 包括但不限于 UMTS和 UTE等。 本发明的另一个实施例提供一种网络侧设备 70，该网络侧设备 70可以包括收发单元 701和处理单元 702。其中， 收发单元 701用于发送 lk准则给 UE， 并接收 UE在 lk准则被满 足时发送的测量报告。 处理单元 702用于根据收发单元 701接收到的测量报告更新该 UE 的 CoMP发送集。 其中， lk准则包括以下任一项 UE发送测量报告的条件： 属于激活集 且不属于所述 CoMP发送集的小区的小区质量大于 CoMP发送集中至少一个小区的小区 质量；或者，属于激活集且不属于所述 CoMP发送集的小区的小区质量大于 CoMP发送集 中至少两个小区的小区质量平均值或加权平均值。本发明其他实施例提供的 lk准则也适 用于本实施例， 此处不再赘述。 可选的， 收发单元 701具体用于向 UE发送测量控制消息， 所述测量控制消息包括 lk 准则和 /或时间信息， 该时间信息用于指示 UE在发送测量报告之前， lk准则被满足的时 长。 可选的， 收发单元 701还用于在发送 lk准则给 UE之前， 获取 NodeB的 CoMP能力信 息和 UE的 CoMP能力信息。 其中， NodeB的 CoMP能力信息包括： NodeB支持 CoMP模 式的指示， UE的所属 NodeB本地小区的协同小区的小区标识， 或 UE的所属 NodeB本地 小区的协同小区的小区索引中的一种或组合。 UE的 CoMP能力信息包括 UE支持 CoMP模 式的指示。 可选的， 收发单元 701具体用于接收 NodeB在审计 Audit过程中发送的响应消 息， 该响应消息包括 NodeB的 CoMP能力信息。 可选的， 收发单元 701具体用于接收 UE 发送的包括 UE的 CoMP能力信息的 RRC连接建立完成消息或者 UE能力信息。 可选的， 收发单元 701接收的测量报告包括： 至少一个满足 lk准则的小区的小区质 量和小区标识； 或者， 至少一个满足 lk准则的小区的小区质量和小区索引。 可选的， 处理单元 702具体用于在满足以下任一项条件时， 将至少一个满足 lk准则 的小区加入 CoMP发送集中，上述条件包括：满足 lk准则的小区具备支持 CoMP模式的能 力； UE当前业务的 QoS要求达到预设要求； 满足 lk准则的小区的小区质量达到预设门 限。 可选的， 收发单元 701具体用于与 NodeB通过无线链路建立过程、 或者无线链路重 配过程、或者无线链路增加过程协商与更新后的 CoMP发送集对应的 CoMP配置。可选的， 收发单元 701具体用于通过激活集更新消息或者其他无线资源管理控制消息向 UE发送 与更新后的 CoMP发送集对应的 CoMP配置。 可选的， 处理单元 702还用于为 UE和 Node对该 UE的 CoMP进行预配置。相应的， 收 发单元 701还用于通知 NodeB激活该 CoMP预配置中至少一个满足 lk准则的小区的 CoMP 配置。进一步的， 收发单元 701还可以用于所述 NodeB向 UE发送 HS-SCCH order消息， 所 述 HS-SCCH order消息用于激活该 CoMP预配置中至少一个满足 lk准则的小区的 CoMP 配置。 其中， 激活该 CoMP预配置中至少一个小区的 CoMP配置包括： 将该 CoMP预配置 中的至少一个满足 lk准则的小区加入该 UE的 CoMP发送集。 可选的， 收发单元 701还用于： 将用于目标 RNC确定所述 UE的新 CoMP配置的信息 发送给 UE的目标 RNC,该用于目标 RNC确定 UE的新 CoMP配置的信息包括： UE的 CoMP 能力信息和 /或 UE是否当前处于 CoMP状态的信息。进一歩的， 当本实施例提供的网络侧 设备为 UE的源 RNC时， 收发单元 701还可以用于： 接收目标 RNC确定该 UE的新 CoMP配 置， 并将该 UE的新 CoMP配置发送给 UE。其中， 该 UE的新 CoMP配置可以携带在切换指 令消息或者 RRC重配置消息中。 本实施例中， 小区质量的表征方式可以包括接收信号码功率 CPICH RSCP、 或者码 片功率谱密度 CPICH Ec/No、 或者路径损耗 CPICH PathLoss。 UE的 CoMP发送集可以包 括： 向 UE发送数据的服务小区和协同小区； 或者， 向 UE发送数据的协同小区。 可选的， 本实施例提供的网络侧设备 70可以是 R C；。 本实施例提供的网络侧设备能够实现更新 CoMP发送集， 从而灵活调整 CoMP协同 小区， 有利于进一步提高小区整体性能及小区边缘用户性能。 本发明的另一个实施例提供一种网络侧设备 80，该网络侧设备 80包括发送单元 801。 其中， 发送单元 801用于向 UE发送 HS-SCCH order消息， 该 HS-SCCH order消息包括激活 指示和 /或去激活指示。 该激活指示用于激活该 UE的 CoMP配置中至少一个小区的 CoMP 配置， 该去激活指示用于去激活该 UE的 CoMP配置中至少一个小区的 CoMP配置。 可选的， 该 HS-SCCH order消息包括激活指示时， 该 HS-SCCH order消息还包括：
