Description

一种小区测量方法、 小区资源共享方法和相关设备 本申请要求于 2011年 7月 12日提交的， 申请号为 201110194605.5 ,发明名 称为 "一种小区测量方法、 小区资源共享方法和相关设备" 的中国申请的优先 权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及通讯领域，尤其涉及一种小区测量方法、小区资源共享方法和相 关设备。
背景技术
在无线通信系统中， 协作多点传输 （ CoMP , Coordinated Multi-Point transmission )技术是提高小区整体性能及小区边缘用户性能的一个重要手段。
CoMP技术需要多种物理层传输技术的支持，如适应多小区联合传输的多输 入多输出 （MIMO, Multiple-Input Multiple-Out-put )技术、 预编码技术、 网络编 码技术、 高效的信道估计和联合检测技术等。 同时， 先进有效的无线资源管理 方案也是影响 CoMP技术性能的重要因素， 如小区资源分配策略、 负载均衡、 联合多点传输中协作小区的选择机制以及有效的切换策略等。 其中切换性能是 衡量移动通信系统性能的重要指标， 有效的切换策略是实现用户无处不在的网 络的关键。
在现有的 CoMP系统中， 用户设备 ( UE, User Equipment )通过与其服务小 区的相邻小区进行同步来获得相邻小区的物理小区标识 （PCI , Physical Cell Identity ), 利用获得的 PCI 分别对 PCI 对应的小区的小区参考信号 （CRS , Cell-specific reference signals )进行测量， 将测量结果作为无线资源管理（ RRM, Radio Resource Management )测量集上报给 UE所在的基站， 基站利用 UE上报 的 RRM测量集来评估该 UE接收到的周边各个小区的信号强度和信号质量， 以 便对该 UE的小区切换进行判决。 在上述方案中， 基站通过 PCI来区分 RRM测 量集中不同小区对应的不同测量结果， 在目前的 CoMP系统中， 当一个小区在 发送 CRS的资源位置信息时，其它小区有可能在该小区发送 CRS的资源位置信 息时占用的时频域资源上发送物理下行控制信道（PDCCH, Physical Downlink Control Channel ) 或物理下行共享信道（PDSCH, Physical Downlink Shared Channel )等资源信息， 从而对该 CRS的资源位置信息产生干扰， 造成 CRS的 测量结果不准确。

具体实施方式
本发明实施例提供了一种小区测量方法、 小区资源共享方法和相关设备。 为使得本发明的发明目的、 特征、 优点能够更加的明显和易懂， 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， 而非全部实施例。 基 于本发明中的实施例， 本领域普通技术人员在没有做出创造性劳动前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
下面以 UE作为描述主体，对本发明实施例中小区测量方法进行描述，请参 阅图 1 , 本发明提供的小区测量方法一个实施例包括：
步骤 101、 接收基站发送的测量配置消息；
在 CoMP系统中，多个地理位置相互独立分散的接入节点（ AP, Access Point ) 通过不同的协作方式（如联合传输、 联合处理、 协作调度等） 为多个 UE服务。 基站通过接收 UE上报的 RRM测量集的测量结果来更新该 UE的 CoMP测量集 并下发给 UE, UE需要上报接收到的 CoMP测量集中的小区的信道状态信息给 基站， 以便基站对 CoMP测量集中的小区进行调度。 基站向 UE发送测量配置 消息，指示 UE依据该测量配置消息对需要测量的小区进行测量， 并将测量的结 果作为 RRM测量集的测量结果上报给该基站。
本发明实施例中， 上述测量配置消息中包含至少一个物理小区标识， 和每 个物理小区标识指示的被测小区的信道状态信息 （ CSI , Channel State Information ) -参考信号 （RS, Reference Signal ) 配置信息； 还可选包括与该被 测小区——对应的配置标识， 还可选的包括测量索引号， 该配置标识可以是被 测小区所属的 AP的天线端口信息和该被测小区的 CSI-RS配置信息的配置索引 号中的至少一个，上述天线端口信息包括但不限于天线端口号和 /或天线端口数， 当然， 由于每个小区对应不同的配置信息， 因此， 为便于基站对各个不同小区 进行管理， 可选的用小区标号对各个不同的小区进行标识， 并建立小区标号与 小区的 CSI-RS配置信息的映射关系，故上述配置标识也可以是上述被测小区的 小区标号， 此处不作限定。
需要说明的是，在实际应用中， 地理位置互异的多个 AP下的小区被配置不 同的天线端口信息， 并对应不同的 CSI-RS配置， 相同物理小区标识指示的不同 被测小区的 CSI-RS配置信息均不相同。 CSI-RS配置信息用于定义 CSI-RS配置， 主要包含 CSI-RS 的天线端口信息、 资源配置信息和子帧配置信息等。 不同的 CSI-RS 配置信息对应不同的配置索引号， 以便于基站对多个 AP 下的小区的 CSI-RS配置信息进行管理。 这些 CSI-RS配置之间可以通过在时域、 频域、 码 域和 /或空间进行区分， 举例说明， 如不同的小区对应的 CSI-RS 配置之间发送 CSI-RS的子帧位置不同 （有子帧偏移）， 和 /或不同的发送周期。
可理解的是， 若同一个 AP包含多条天线， 即一个 AP对应于多个小区， 则 该 AP不同天线下的小区也对应于不同的 CSI-RS配置， 该 AP的多条天线对应 不同的天线端口信息。
上述 AP可以是具有完整资源管理模块、 基带处理模块和射频单元的基站， 或者可以是无线信号收发器（ RRH, Remote Radio Head )、射频拉远单元（ RRU, Radio Remote Unit )及天线， 也可以是中继器， 此处不作限定。
上述测量配置消息还可选的包括被测小区的测量指示信息， 如 CSI-RSRP 测量指示信息和 /或 CSI-RSRQ测量指示信息； 上述测量配置消息还可选的包括 测量上报方式指示信息，用于指示 UE对被测小区进行周期性测量上报或事件性 测量上报， 如果测量上报方式指示信息指示的上报方式是事件性测量上报， 则 测量配置消息中还可包括配置迟滞值和迟滞时间， 最大报告被测小区数以及报 告次数， 和 /或其他辅助配置参数， 如层三平滑过滤等参数。 如果测量上报方式 指示信息指示的上报方式是周期性测量上报， 则测量配置消息中还可包括配置 报告周期， 当然， 上述各参数也可是默认预置在 UE中的， 此处不作限定。
上述测量配置消息可以是基于无线资源控制 （RRC, Radio Resource Control) 协议的信令， 即 RRC信令， 或者也可以是 RRC 重配置消息的一部分， 或是基 于媒体接入控制 （MAC, Medium/MediaAccess Control )协议的信令， 即 MAC 信令， 此处不作限定。
步骤 102、 对被测小区对应的 CSI-RS进行测量， 获取测量结果；
UE在接收到基站发送的测量配置消息后， 可根据测量配置消息中的相同物 理小区标识指示的被测小区的 CSI-RS配置信息和 /或该被测小区的配置标识（如 天线端口信息或 CSI配置信息的配置索引号） 的差异来区分相同物理小区标识 指示的不同被测小区， 还可选的对相同物理小区标识指示的不同被测小区的资 源进行区分测量的操作。 UE可利用不同被测小区的 CSI-RS配置信息对相应的 被测小区的 CSI-RS 进行测量， 获取该被测小区的测量结果， 如被测小区的 CSI-RSRP和 /或 CSI-RSRQ等， 例如在实际应用中， UE可通过对该被测小区的 CSI-RS 进行测量， 获得该被测小区接收信号的信号与干扰加噪声比 （SINR, Signal to Interference plus Noise Ratio ), 通过 SINR计算得到该被测小区的 CSI-RSRP 和 /或 CSI-RSRQ。 可选的， UE可将测量结果和测量配置消息中的 CSI-RS配置信息、 被测小区的配置标识和测量索引号中的至少一个进行绑定。 在实际应用中， UE可周期性地测量上报被测小区的测量结果， 若 UE接收到的 测量配置消息包含测量指示信息， 如 CSI-RSRP测量指示信息和 /或 CSI-RSRQ 测量指示信息， 则 UE可依据测量指示信息获取基站所需要的测量值，将该测量 值作为测量结果上报给基站， 例如，若测量请求消息中包含 CSI-RSRP测量指示 信息， 则 UE获取被测小区的 CSI-RSRP, 若测量请求消息中包含 CSI-RSRQ测 量指示信息，则 UE获取被测小区 CSI-RSRQ,若测量请求消息中包含 CSI-RSRP 测量指示信息和 CSI-RSRQ测量指示信息，则 UE获取被测小区的 CSI-RSRP和 CSI-RSRQ。 当然， UE也可在接收到测量配置消息时， 根据预定的设置默认获 取被测小区的 CSI-RSRP和 /或 CSI-RSRQ, 此处不作限定。
步骤 103、将获取到的被测小区的测量结果以及测量对象信息， 通过测量报 告发送给基站；
UE将获取到的被测小区的测量结果以及指示该被测小区的测量对象信息， 通过测量报告发送给基站。
在实际应用中， 当 UE周期性上报该测量报告给基站时，上述测量结果可以 包括 CSI-RSRP和 /或 CSI-RSRQ等测量量结果， 当 UE事件性上报该测量报告 给基站时， 上述测量结果例如可以是 CSI-RSRP和 /或 CSI-RSRQ等测量量结果 和 /或测量事件指示信息， 该测量事件指示信息用于指示该被测小区是满足进入 协作多点传输 CoMP测量集的条件的小区或者是满足离开 CoMP测量集的条件 的小区。 上述测量对象信息可以包括测量配置消息中的 CSI-RS配置信息、 该被 测小区所属的接入节点的天线端口信息， 以及被测小区的小区标号中的至少一 个， 或者也可以包括测量索引号。
基站可依据获取到的测量报告中的上述测量对象信息区分不同被测小区对 应的测量结果， 并根据各个被测小区的被测结果更新该 UE的 CoMP测量集。 进一步的， 基站也可利用该测量报告进行其它操作处理， 如基站可利用该测量 报告来对该 UE进行移动性管理。
UE也可通过事件性测量上报将上述测量报告上报给基站， 在实际应用中， UE可利用测量获取到的各个被测小区 CSI-RSRP和 /或 CSI-RSRQ计算出满足进 入其 CoMP测量集或者离开 CoMP测量集的条件的被测小区， 并可只发送满足 进入 CoMP测量集的条件的被测小区的 CSI-RSRP和 /或 CSI-RSRQ给基站， 或 者， UE也可只发送满足离开 CoMP测量集的条件的被测小区的 CSI-RSRP和 / 或 CSI-RSRQ给基站， 或者， UE也可在计算出满足进入其 CoMP测量集和 /或 离开其 CoMP测量集的条件的被测小区后， 用不同的测量事件指示信息来区分 满足进入该 UE的 CoMP测量集的条件的被测小区和满足离开该 UE的 CoMP 测量集的条件的被测小区， 将上述测量事件指示信息、 满足进入该 UE的 CoMP 测量集的条件的被测小区的信号测量值（CSI-RSRP和 /或 CSI-RSRQ ), 以及满 足离开该 UE的 CoMP测量集的条件的被测小区的信号测量值（CSI-RSRP和 / 或 CSI-RSRQ )中的至少一个作为测量结果上报给基站，基站可通过测量事件指 示信息获知哪些被测小区满足进入该 UE的 CoMP测量集的条件， 哪些被测小 区满足离开该 UE的 CoMP测量集的条件， 当然， UE也可将测量获取到的所有 被测小区的 CSI-RSRP和 /或 CSI-RSRQ发送基站， 由基站计算出满足进入或离 开 CoMP测量集的条件的小区， 来更新该 UE的 CoMP测量集， 此处不作限定。
由上可见， 本发明实施例中通过在测量配置消息中携带至少一个物理小区 小区标识， 及该物理小区标识指示的被测小区的 CSI- RS配置信息； 使 UE可对 被测小区的 CSI-RS进行测量并获取测量结果，将该被测小区的测量结果以及指 示该被测小区的测量对象信息， 通过测量报告发送给基站， 一方面， UE可根 据测量配置消息中的相同物理小区标识指示的被测小区的 CSI-RS 配置信息和 / 或配置标识的差异来区分相同物理小区标识指示的不同被测小区的资源， 另一 方面， 基站可依据上述测量对象信息区分不同被测小区的测量结果， 从而有效 更新该 UE的 CoMP测量集； 进一步的， 由于在 CoMP系统中， 当一个小区发 送 CSI-RS的资源位置时， 其它小区将不在该小区发送 CSI-RS的资源位置时占 用的时频域资源上发送数据， 避免了数据间的干扰， 因此， UE对 CSI-RS进行 测量得到的测量结果比对 CRS进行测量得到的测量结果更为准确。
下面同样以 UE作为描述主体，对本发明实施例中的一种小区测量方法进行 进一步描述， 请参阅图 2, 本发明提供的一种小区测量方法的另一实施例包括： 步骤 201、 接收基站发送的测量配置消息；
其具体的步骤描述可与图 1步骤 101类似， 可参照步骤 101中的描述， 此 处不再赘述。
步骤 202、 获取被测小区的 CSI-RSRP和 /或 CSI-RSRQ;
UE在接收到基站发送的测量配置消息后， 可根据测量配置消息中的相同物 理小区标识指示的被测小区的 CSI-RS配置信息和 /或该被测小区的配置标识（如 天线端口信息或 CSI配置信息的配置索引号） 的差异来区分相同物理小区标识 指示的不同被测小区的资源， 还可选的对相同物理小区标识指示的被测小区的 资源进行区分测量的操作。 UE可利用不同被测小区的 CSI-RS配置信息对相应 的被测小区的 CSI-RS进行测量，获取该被测小区的 CSI-RSRP和 /或 CSI-RSRQ, 如可通过对该小区的 CSI-RS进行测量，获得该小区接收信号的 SINR,通过 SINR 计算得到该小区的 CSI-RSRP和 /或 CSI-RSRQ。可选的，将测量结果和测量配置 消息中的 CSI-RS配置信息、被测小区的的配置标识和测量索引号中的至少一个 进行绑定。
在实际应用中， UE可将获取到的被测小区的 CSI-RSRP和 /或 CSI-RSRQ作 为该被测小区的测量结果，周期性地测量上报给基站。若 UE接收到的测量配置 消息包含测量指示信息， 如 CSI-RSRP测量指示信息和 /或 CSI-RSRQ测量指示 信息， 则 UE可依据测量指示信息获取基站所需要的测量值，将该测量值作为测 量结果上报给基站。 例如， 若测量配置消息中包含 CSI-RSRP测量指示信息， 则 UE获取被测小区的 CSI-RSRP, 若测量请求消息中包含 CSI-RSRQ测量指示信 息， 则 UE获取被测小区 CSI-RSRQ, 若测量请求消息中包含 CSI-RSRP测量指 示信息和 CSI-RSRQ 测量指示信息， 则 UE 获取被测小区的 CSI-RSRP 和 CSI-RSRQ。 当然， UE也可在接收到测量配置消息时， 根据预定的设置默认获 取被测小区的 CSI-RSRP和 /或 CSI-RSRQ, 此处不作限定。
步骤 203、 计算满足进入或离开 CoMP测量集的条件的小区；
UE可利用获取到的各个被测小区的 CSI-RSRP和 /或 CSI-RSRQ计算满足进 入或离开该 UE的 CoMP测量集的条件的小区。
为便于描述，下面将 UE获得的各个被测小区的 CSI-RSRP/或 CSI-RSRQ称 为被测小区的信号测量值， 将 UE 当前 CoMP 测量集中信号最优的小区的 CSI-RSRP/或 CSI-RSRQ称为最优小区的信号测量值， 则， 具体的判定被测小区 是否满足进入或离开该 UE的 CoMP测量集的条件可以是： 将被测小区的信号 测量值加上该被测小区进入该 UE的 CoMP测量集的信号偏移量得到的和（假 定为 S1 ) ,跟该 UE当前 CoMP测量集中所有小区的信号测量值的加权平均值加 上该被测小区进入该 UE的 CoMP测量集的信号迟滞得到的和（假定为 S2 )进 行比较， 若 S1大于或等于 S2, 则确定该被测小区满足进入该 UE的 CoMP测量 集的条件， 若 S1小于 S2, 则确定该被测小区满足离开该 UE的 CoMP测量集的 条件； 或者， 也可将被测小区的信号测量值加上该被测小区进入该 UE的 CoMP 测量集的信号偏移量得到的和（假定为 S1 ), 跟该 UE当前 CoMP测量集中的最 优小区（或者也可以是该 UE的服务小区）的信号测量值加上该最优小区的信号 偏移量再加上该被测小区进入该 UE的 CoMP测量集的信号迟滞得到的和（假 定为 S2 )进行比较， 若 S1 大于或等于 S2, 则确定该被测小区满足进入该 UE 的 CoMP测量集的条件， 若 S1小于 S2, 则确定该被测小区满足离开该 UE的 CoMP测量集的条件， 当然， 也可根据实际情况设定该被测小区满足或离开该 UE的 CoMP测量集的条件， 此处不作限定。
步骤 204、 将满足进入和 /或离开 CoMP测量集的条件的被测小区的信号测 量值和 /或测量事件指示信息上报给基站；
UE可在步骤 203后将满足进入和 /或离开 CoMP测量集的条件的被测小区 的信号测量值（即 CSI-RSRP和 /或 CSI-RSRQ )上报给基站， 或者， UE也可用 不同的测量事件指示信息来区分满足进入该 UE的 CoMP测量集的条件的被测 小区和满足离开该 UE的 CoMP测量集的条件的被测小区， 将上述测量事件指 示信息、满足进入该 UE的 CoMP测量集的条件的小区的信号测量值（ CSI-RSRP 和 /或 CSI-RSRQ ) , 以及满足离开该 UE的 CoMP测量集的条件的小区的信号测 量值（ CSI-RSRP和 /或 CSI-RSRQ ) 中的至少一个作为测量结果， 与相应的测量 对象信息绑定后上报给基站。
由上可见， 本发明实施例中通过在测量配置消息中携带至少一个物理小区 小区标识， 及该物理小区标识指示的被测小区的 CSI- RS配置信息； 使 UE可对 被测小区的 CSI-RS进行测量并获取该被测小区的测量结果， 并将该被测小区的 测量结果以及指示该被测小区的测量对象信息， 通过测量报告发送给基站， 一 方面， UE 可根据测量配置消息中的相同物理小区标识指示的被测小区的 CSI-RS 配置信息和 /或配置标识的差异来区分相同物理小区标识指示的不同被 测小区的资源， 另一方面， 基站可依据上述测量对象信息区分不同被测小区的 测量结果， 从而有效更新该 UE的 CoMP测量集； 进一步的， 由于在 CoMP系 统中， 当一个小区发送 CSI-RS 的资源位置时， 其它小区将不在该小区发送 CSI-RS的资源位置时占用的时频域资源上发送数据， 避免了数据间的干扰， 因 此， UE对 CSI-RS进行测量得到的测量结果比对 CRS进行测量得到的测量结果 更为准确。
下面以基站作为描述主体， 对本发明实施例中一种小区测量方法进行描述， 请参阅图 3, 本发明提供的一种小区测量方法再一个实施例包括：
步骤 301、 向用户设备 UE发送测量配置消息；
基站向 UE发送测量配置消息，并在该测量配置消息中携带至少一个物理小 区标识， 以及每个物理小区标识指示的被测小区的 CSI-RS配置信息； 还可选包 括和与该被测小区——对应的配置标识， 还可选的包括测量索引号， 该配置标 识可以是该被测小区所属的 AP的天线端口信息、 该被测小区的 CSI-RS配置信 息的配置索引号， 以及该被测小区的小区标号中的至少一个。 上述天线端口信 息包括但不限于天线端口号和 /或天线端口数， 当然， 由于每个小区对应不同的 配置信息， 因此， 为便于基站对各个不同小区进行管理， 可选的用小区标号对 各个不同的小区进行标识， 并建立小区标号与小区的 CSI-RS配置信息的映射关 系， 故上述配置标识也可以是上述被测小区的小区标号， 此处不作限定。
需要说明的是，在实际应用中， 地理位置互异的多个 AP下的小区被配置不 同的天线端口信息， 并对应不同的 CSI-RS配置， 相同物理小区标识指示的不同 被测小区的 CSI-RS配置信息均不相同。 CSI-RS配置信息用于定义 CSI-RS配置， 主要包含 CSI-RS 的天线端口信息、 资源配置信息和子帧配置信息等。 不同的 CSI-RS 配置信息对应不同的配置索引号， 以便于基站对多个 AP 下的小区的 CSI-RS配置信息进行管理。 这些 CSI-RS配置之间可以通过在时域、 频域、 码 域和 /或空间进行区分， 举例说明， 如不同的小区对应的 CSI-RS 配置之间发送 CSI-RS的子帧位置不同 （有子帧偏移）， 和 /或不同的发送周期。
可理解的是， 若同一个 AP包含多条天线， 即一个 AP对应于多个小区， 则 该 AP不同天线下的小区也对应于不同的 CSI-RS配置， 该 AP的多条天线对应 不同的天线端口信息。
基站也可在该测量配置消息中携带测量指示信息，如 CSI-RSRP测量指示信 息和 /或 CSI-RSRQ测量指示信息， 以指示 UE测量获取被测小区的 CSI-RSRP 和 /或 CSI-RSRQ。 在实际应用中， 基站还可向与其有接口连接的其它基站发送 测量配置请求消息， 以指示其它基站返回各自覆盖范围内的小区的测量配置信 息， 该测量配置信息包括但不限于 CSI-RS配置信息（可以是特定 UE专属或者 特定小区专属的 CSI-RS配置信息 )和逻辑天线端口信息中的至少一个， 若上述 小区所属的 AP下只存在一个小区， 则上述测量配置信息也可以包括该 AP的标 号等， 如可通过 X2口或 S1口向其它基站发送测量配置请求消息； 基站也可通 过 X2口或 SI口来接收来自其它基站的测量配置信息； 基站也可在接收到网络 中其它基站的测量配置请求消息后， 向其它基站返回本地覆盖范围内的小区的 测量配置消息， 例如可通过 X2口或 S1口向其它基站返回本地覆盖范围内的小 区的测量配置消息。 当然， 基站也可主动向其它基站发送本地覆盖范围内的小 区的测量配置信息， 例如可通过 X2口或 S1口主动向其它基站返回本地覆盖范 围内的小区的 CSI-RS配置信息及该小区的配置标识， 此处不作限定。
上述测量配置请求消息和 /或测量配置消息可以是新的独立消息， 也可以合 并到现有技术中的 X2 或 S1 消息中， 如 "资源状态请求 /回复（RESOURCE STATUS REQUEST/RESPONSE ) " 或 " X2 建立请求 /回复 （ X2 SETUP REQUEST/RESPONSE )"或 "eNB配置更新 /更新回复（ ENB CONFIGURATION UPDATE I UPDATE ACKNOWLEDGE ) " 或 "切换请求 /切换请求回复 荷信息（ Load information )，， 等， 此处不作限定。
上述 AP可以是具有完整资源管理模块、 基带处理模块和射频单元的基站， 或者可以是 RRH、 RRU及天线， 也可以是中继器， 此处不作限定。
步骤 302、 接收用户设备发送的测量报告；
上述测量^艮告包括测量结果和测量对象信息。 上述测量对象信息可以包括 测量配置消息中的 CSI-RS配置信息、该被测小区所属的接入节点的天线端口信 息、 被测小区的配置标识， 该被测小区的小区标号， 以及测量索引号中的至少 一个。 上述测量结果可包括被测小区的 CSI-RSRP、 CSI-RSRQ, 和测量事件指 示信息中的至少一个。
基站接收 UE返回的被测小区的测量报告，基站可依据测量对象信息区分各 个被测小区的测量结果。
步骤 303、 根据接收到的测量报告， 更新用户设备的 CoMP测量集； 基站可在接收到 UE发送的测量报告，依据测量对象信息区分不同被测小区 的 CSI-RSRP和 /或 CSI-RSRQ, 并对该 UE的 CoMP测量集进行更新， 具体的， 基站可根据测量报告中的被测小区的测量结果（如被测小区的 CSI-RSRP和 /或 CSI-RSRQ )计算出该满足进入或离开该 UE的 CoMP测量集的条件的被测小区， 若被测小区为该 UE当前 CoMP测量集中的小区， 但基站计算出该被测小区当 前已不满足进入该 UE的 CoMP测量集的条件（即满足离开该 UE的 CoMP测量 集的条件）， 则将该被测小区移出该 UE的 CoMP测量集， 同理， 若被测小区不 在该 UE当前 CoMP测量集中，但基站计算出该被测小区当前满足进入该 UE的 CoMP测量集的条件， 则将该被测小区移入该 UE当前 CoMP测量集中， 当然， 也可由 UE计算出满足进入和 /或离开该 UE的 CoMP测量集的条件的被测小区 后， 再将满足进入和 /或离开该 UE的 CoMP测量集的条件的被测小区的测量结 果（如被测小区的 CSI-RSRP和 /或 CSI-RSRQ和 /或测量事件指示信息）上报给 基站，由基站进一步判决 UE上报的被测小区是否符合进入 UE的 CoMP测量集， 对该 UE的 CoMP测量集进行更新。
当然， 在实际应用中， 基站也可利用该测量报告进行其它操作处理， 如基 站可利用该测量 ^艮告来对该 UE进行移动性管理。
步骤 304、 基站将更新后的 CoMP测量集发送给该用户设备；
基站在更新完上述 UE的 CoMP测量集后， 将更新后的 CoMP测量集发送 给该 UE。
由上可见， 本发明实施例中通过在测量配置消息中携带至少一个物理小区 小区标识， 及该物理小区标识指示的被测小区的 CSI- RS配置信息； 使 UE可对 被测小区的 CSI-RS进行测量并获取测量结果，将该被测小区的测量结果以及指 示该被测小区的测量对象信息， 通过测量报告发送给基站， 一方面， UE可根 据测量配置消息中的相同物理小区标识指示的被测小区的 CSI-RS 配置信息和 / 或配置标识的差异来区分相同物理小区标识指示的不同被测小区的资源， 另一 方面， 基站可依据上述测量对象信息区分不同被测小区的测量结果， 从而有效 更新该 UE的 CoMP测量集； 进一步的， 由于在 CoMP系统中， 当一个小区发 送 CSI-RS的资源位置时， 其它小区将不在该小区发送 CSI-RS的资源位置时占 用的时频域资源上发送数据， 避免了数据间的干扰， 因此， UE对 CSI-RS进行 测量得到的测量结果比对 CRS进行测量得到的测量结果更为准确。
为便于更好地理解本发明技术方案， 下面以一具体应用场景为例， 对本发 明实施例一种小区测量方法中进行描述， 假设本发明实施例中的网络组网结构 图如图 4-a所示， 基站 40下有 AP41、 AP42、 AP43和 AP44四个接入节点， 每 个 AP包含一个小区， AP41、 AP42、 AP43和 AP44具有相同的 PCI, 用户设备 45当前的 CoMP测量集中包含 AP41、 AP42和 AP43。 请参阅图 4-b, 上述应用 场景下的基站与 UE的交互过程包括： 步骤 401、 基站向 UE发送测量配置消息；

上述配置标识可以是上述四个 AP的天线端口信息，和 /或上述四个 AP下的 小区的 CSI-RS配置信息的配置索引号， 当然， 也可以是上述四个 AP下的小区 的小区标号， 此处不作限定。
步骤 402、 UE获取被测小区的 CSI-RSRP和 /或 CSI-RSRQ;
在本发明实施例中， UE在接收到基站发送的测量请求消息后， 依据测量请 求消息中的 CSI-RS配置信息分别对上述四个 AP下的小区进行 CSI-RS测量， 默认获取或者依据测量请求消息中的 CSI-RSRP测量指示信息和 /或 CSI-RSRQ 测量指示信息， 获取上述四个 AP下的小区的 CSI-RSRP和 /或 CSI-RSRQ。
步骤 403、 UE向基站发送测量报告；
UE将获取到的被测小区的 CSI-RSRP和 /或 CSI-RSRQ作为测量结果，将该 测量结果及测量对象信息通过测量报告发送给基站。
上述测量对象信息可包括测量配置消息中的 CSI-RS 配置信息和 /或上述四 个 AP的天线端口信息， 和 /或对应的测量索引号。
步骤 404、 基站更新该 UE的 CoMP测量集；
基站在接收到 UE发送的被测小区的 CSI-RSRP和 /或 CSI-RSRQ后， 可依 据测量 4艮告中的测量对象信息区分不同被测小区对应的 CSI-RSRP 和 /或 CSI-RSRQ, 并根据各个被测小区的 CSI-RSRP和 /或 CSI-RSRQ更新该 UE的 CoMP测量集。
步骤 405、 基站将更新后的该 UE的 CoMP测量集下发给该 UE。
上述 AP可以是具有完整资源管理模块、 基带处理模块和射频单元的基站， 或者可以 RRH、 RRU及天线， 也可以是中继器， 此处不作限定。
由上可见， 本发明实施例中通过在测量配置消息中携带至少一个物理小区 小区标识，及该物理小区标识指示的至少一个被测小区的 CSI- RS配置信息；使 UE可对被测小区的 CSI-RS进行测量并获取测量结果， 将该被测小区的测量结 果以及指示该被测小区的测量对象信息，通过测量报告发送给基站，一方面， UE 可根据测量配置消息中的相同物理小区标识指示的被测小区的 CSI-RS配置信息 和 /或配置标识的差异来区分相同物理小区标识指示的不同被测小区的资源， 另 一方面， 基站可依据上述测量对象信息区分不同被测小区的测量结果， 从而有 效更新该 UE的 CoMP测量集； 进一步的， 由于在 CoMP系统中， 当一个小区 发送 CSI-RS的资源位置时， 其它小区将不在该小区发送 CSI-RS的资源位置时 占用的时频域资源上发送数据， 避免了数据间的干扰， 因此， UE对 CSI-RS进 行测量得到的测量结果比对 CRS进行测量得到的测量结果更为准确。
下面以一具体应用场景为例， 对本发明实施例一种小区测量方法进一步进 行描述， 假设本发明实施例中的组网结构图同样如图 4-a所示， 基站 40 下有 AP41、 AP42、 AP43和 AP44四个接入节点， 每个 AP包含一个小区， AP41、 AP42、 AP43和 AP44具有相同的 PCI, 用户设备 45当前的 CoMP测量集中包 含 AP41、 AP42和 AP43下的小区， 具体的交互流程请参阅图 5：
步骤 501、 基站向 UE发送测量配置消息；
基站向 UE发送测量配置消息， 上述测量配置消息包含 AP41、 AP42、 AP43 和 AP44下的 PCI, 各个 AP下的被测小区的 CSI-RS配置信息以及与各被测小 区——对应的配置标识。
基站也可在该测量配置消息中携带测量指示信息，如 CSI-RSRP测量指示信 息和 /或 CSI-RSRQ测量指示信息， 以指示 UE获取被测小区的 CSI-RSRP和 /或 CSI-RSRQ„
上述配置标识可以是上述四个 AP的天线端口信息，和 /或上述四个 AP下的 小区的 CSI-RS配置信息的配置索引号， 当然， 也可以是上述四个 AP下的小区 的小区标号， 此处不作限定。
步骤 502、 UE获取被测小区的 CSI-RSRP和 /或 CSI-RSRQ;
在本发明实施例中， UE在接收到基站发送的测量请求消息后， 依据测量请 求消息中的 CSI-RS配置信息分别对上述四个 AP下的小区进行 CSI-RS测量， 默认获取或者依据测量请求消息中的 CSI-RSRP测量指示信息和 /或 CSI-RSRQ 测量指示信息， 获取上述四个 AP下的小区的 CSI-RSRP和 /或 CSI-RSRQ。
步骤 503、 UE计算出满足进入或离开 CoMP测量集的条件的被测小区； UE可利用获取到的各个被测小区的 CSI-RSRP和 /或 CSI-RSRQ, 计算出满 足进入或离开该 UE的 CoMP测量集的条件的被测小区。
为便于描述，将 UE获得的各个被测小区的 CSI-RSRP/或 CSI-RSRQ称为被 测小区的信号测量值，将 UE当前 CoMP测量集中信号最优的小区的 CSI-RSRP/ 或 CSI-RSRQ称为最优小区的信号测量值， 则， 具体的判定被测小区是否满足 进入或离开该 UE的 CoMP测量集的条件可以是： 将被测小区的信号测量值加 上该被测小区进入该 UE的 CoMP测量集的信号偏移量得到的和（假定为 S1 ), 跟该 UE当前 CoMP测量集中所有小区的信号测量值的加权平均值加上该被测 小区进入该 UE的 CoMP测量集的信号迟滞得到的和（假定为 S2 )进行比较， 若 S1大于或等于 S2,则确定该被测小区满足进入该 UE的 CoMP测量集的条件， 若 S1小于 S2,则确定该被测小区满足离开该 UE的 CoMP测量集的条件；或者， 也可将被测小区的信号测量值加上该被测小区进入该 UE的 CoMP测量集的信 号偏移量得到的和（假定为 S1 ), 跟该 UE当前 CoMP测量集中的最优小区（或 者也可以是该 UE的服务小区）的信号测量值加上该最优小区的信号偏移量再加 上该被测小区进入该 UE的 CoMP测量集的信号迟滞得到的和（假定为 S2 )进 行比较， 若 S1大于或等于 S2, 则确定该被测小区满足进入该 UE的 CoMP测量 集的条件， 若 S1小于 S2, 则确定该被测小区满足离开该 UE的 CoMP测量集的 条件， 当然， 也可根据实际情况设定该被测小区满足或离开该 UE的 CoMP测 量集的条件， 此处不作限定。
步骤 504、 将满足进入和 /或离开 CoMP测量集的条件的被测小区的信号测 量值上报和 /或测量事件指示信息给基站；
UE可在步骤 503后将满足进入和 /或离开 CoMP测量集的条件的被测小区 的信号测量值（即 CSI-RSRP和 /或 CSI-RSRQ )上报给基站， 或者， UE也可用 不同的测量事件指示信息来区分满足进入该 UE的 CoMP测量集的条件的被测 小区和满足离开该 UE的 CoMP测量集的条件的被测小区， 将上述测量事件指 示信息、满足进入该 UE的 CoMP测量集的条件的小区的信号测量值（ CSI-RSRP 和 /或 CSI-RSRQ )和满足离开该 UE的 CoMP测量集的条件的小区的信号测量 值（ CSI-RSRP和 /或 CSI-RSRQ ) 中的至少一个作为测量结果， 与相应的测量对 象信息绑定后上报给基站。
假设在步骤 503中， UE通过计算， 判定 AP41、 AP42和 AP44三个接入节 点下的被测小区满足进入该 UE的 CoMP测量集， AP43 下的小区满足离开该 UE的 CoMP测量集的条件， 则 UE可将满足进入该 UE的 CoMP测量集的条件 的 AP41、 AP42和 AP44三个接入节点下的小区的信号测量值（ CSI-RSRP和 / 或 CSI-RSRQ )与上述三个接入节点下的小区的测量对象信息对应绑定后发送给 基站，或者也可将满足离开该 UE的 CoMP测量集的条件的 AP43下的小区的信 号测量值（ CSI-RSRP和 /或 CSI-RSRQ ) 与 AP43下的小区的测量对象信息绑定 后发送给基站， 或者也可用不同的测量事件指示信息分别标识出 AP41、 AP42 和 AP44三个接入节点下的小区为满足进入该 UE的 CoMP测量集的条件的小 区， AP43下的小区为满足离开该 UE的 CoMP测量集的条件的小区， 将上述测 量事件指示信息， 和 /或， AP41、 AP42与 AP44三个接入节点下的小区的信号测 量值 （CSI-RSRP 和 /或 CSI-RSRQ ) , 和 /或 AP43 下的小区的信号测量值 ( CSI-RSRP和 /或 CSI-RSRQ )与相应的测量对象信息绑定后上报给基站， 此处 不作限定。
步骤 505、 基站更新该 UE的 CoMP测量集；
基站在接收到步骤 504中 UE发送的被测小区的信号测量值后，可依据预定 的策略（如预定 UE只上报满足进入该 UE的 CoMP测量集的小区， 或只上报满 足离开该 UE的 CoMP测量集的小区）或者依据接收到的测量事件指示信息， 进一步判决符合进入该 UE的 CoMP测量集的小区，更新该 UE的 CoMP测量集。
如若基站判决出此时 AP41、 AP42和 AP44三个接入节点下的小区满足进入 该 UE的 CoMP测量集，AP43下的小区满足离开该 UE的 CoMP测量集的条件， 则将 UE的当前的 CoMP测量集包含的小区更新为 AP41、 AP42和 AP44下的小 区。
步骤 506、 基站将更新后的该 UE的 CoMP测量集下发给该 UE。
上述 AP可以是具有完整资源管理模块、 基带处理模块和射频单元的基站， 或者可以 RRH、 RRU及天线， 也可以是中继器， 此处不作限定。
由上可见， 本发明实施例中通过在测量配置消息中携带至少一个物理小区 小区标识， 及该物理小区标识指示的被测小区的 CSI- RS配置信息； 使 UE可对 被测小区的 CSI-RS进行测量并获取测量结果， 并将该被测小区的测量结果以及 指示该被测小区的测量对象信息， 通过测量报告发送给基站， 一方面， UE可 根据测量配置消息中的相同物理小区标识指示的被测小区的 CSI-RS配置信息和 /或配置标识的差异来区分相同物理小区标识指示的不同被测小区的资源， 另一 方面， 基站可依据上述测量对象信息区分不同被测小区的测量结果， 从而有效 更新该 UE的 CoMP测量集； 进一步的， 由于在 CoMP系统中， 当一个小区发 送 CSI-RS的资源位置时， 其它小区将不在该小区发送 CSI-RS的资源位置时占 用的时频域资源上发送数据， 避免了数据间的干扰， 因此， UE对 CSI-RS进行 测量得到的测量结果比对 CRS进行测量得到的测量结果更为准确。

可理解的是， 若同一个 AP包含多条天线， 即一个 AP对应于多个小区， 则 该 AP不同天线下的小区也对应于不同的天线端口信息， 如天线端口号和 /或天 线端口数。
上述 AP可以是具有完整资源管理模块、 基带处理模块和射频单元的基站， 或者可以是 RRH、 RRU, 及天线， 也可以是中继器， 此处不作限定。

在实际应用中， UE可周期性地测量获取被测小区的 RSRP和 /或 RSRQ。 若 UE接收到的测量请求消息包含测量指示信息， 如 RSRP 测量指示信息和 /或 RSRQ测量指示信息， 则 UE可依据测量指示信息获取基站所需要的测量值。 例 如，若测量请求消息中包含 RSRP测量指示信息，则 UE获取被测小区的 RSRP, 若测量请求消息中包含 RSRQ测量指示信息， 则 UE获取被测小区 RSRQ, 若测 量请求消息中包含 RSRP测量指示信息和 RSRQ测量指示信息，则 UE获取被测 小区的 RSRP和 RSRQ。 当然， UE也可在接收到测量配置消息时， 根据预定的 设置默认获取被测小区的 RSRP和 /或 RSRQ, 此处不作限定。
步骤 603、将获取到的被测小区的测量结果以及该被测小区的配置标识， 通 过测量报告发送给基站；
UE将测量获取到的被测小区的测量结果（如 RSRP和 /或 RSRQ ), 与该被 测小区的配置标识绑定后， 通过测量报告发送给基站， 基站可依据上述配置标 识区分不同被测小区对应的测量结果， 并根据各个被测小区的测量结果更新该 UE的 CoMP测量集。
例如， UE可在接收到来自基站的测量配置消息后， 周期性上报各个被测小 区的 RSRP和 /或 RSRQ给基站， 或者， UE也可在获得各个被测小区的 RSRP 和 /或 RSRQ后， 事件性将上述各个被测小区的 RSRP和 /或 RSRQ上报给基站， 如在实际应用中， UE可利用获取到的各个被测小区的 RSRP和 /或 RSRQ计算 出满足进入其 CoMP测量集或者离开 CoMP测量集的条件的小区， 并可只发送 满足进入 CoMP测量集的条件的被测小区的 RSRP和 /或 RSRQ给基站， 或者， UE也可只发送满足离开 CoMP测量集的条件的被测小区的 RSRP和 /或 RSRQ 给基站， 或者， UE也可利用获取到的各个被测小区的 RSRP和 /或 RSRQ计算 出满足进入其 CoMP测量集和 /或离开其 CoMP测量集的条件的被测小区， 并用 不同的测量事件指示信息来区分满足进入和 /或离开该 UE的 CoMP测量集的条 件的小区和， 将上述测量事件指示信息和 /或满足进入该 UE的 CoMP测量集的 条件的小区的信号测量值（RSRP和 /或 RSRQ )和 /或满足离开该 UE的 CoMP 测量集的条件的小区的信号测量值（ RSRP和 /或 RSRQ )上报给基站， 基站可通 过测量事件指示信息获知哪些小区满足进入该 UE的 CoMP测量集的条件， 哪 些小区满足离开该 UE的 CoMP测量集的条件， 当然， UE也可将测量获取到的 所有被测小区的 RSRP和 /或 RSRQ发送基站，由基站计算满足进入或离开 CoMP 测量集的条件的小区， 来更新该 UE的 CoMP测量集， 此处不作限定。
进一步的， UE还可根据各个被测小区的 RSRP和 /或 RSRQ对该 UE进行测 量管理和移动性管理， 如打开异频测量， 或进行小区的切换， 或进行小区干扰 十办调 ( ICIC, Inter-Cell Interference Coordination )等。
由上可见， 本发明实施例中通过在测量配置消息中携带被测接入节点下的 被测小区的配置标识，使 UE可根据测量配置消息中的配置标识来区分不同的被 测小区， 并将对该被测小区进行 CRS测量得到的测量结果与该被测小区的配置 标识绑定后上报给基站， 使基站可依据配置标识区分不同被测小区的测量结果， 从而有效更新该 UE的 CoMP测量集。

步骤 802、 基站 2向基站 1返回测量配置信息；
当基站 2接收到基站 1发送的测量配置请求消息时， 基站 2响应基站 1的 测量配置请求消息， 将本地覆盖范围下内的小区的测量配置信息发送给基站 1。
在实际应用中， 基站 2可通过 X2或 S1口向基站 1发送本地覆盖范围内的 小区的上述测量配置信息。
上述测量配置请求消息和 /或测量配置消息可以是新的独立消息， 也可以合 并到现有技术中的 X2或 S1消息中， 如 "资源状态请求 /回复" 或 "X2建立请 求 /回复" 或 "eNB配置更新 /更新回复"或 "切换请求 /切换请求回复"或 "负荷 信息" 等， 此处不作限定。
需要说明的是， 本发明实施例是基站在接收到其它基站发送的测量配置请 求消息后， 向相应基站返回本地覆盖范围内的小区的测量配置信息， 在实际应 用中， 基站也可主动的向与其由接口连接的其它基站下发本地覆盖范围内的小 区的测量配置信息， 此处不作限定。 步骤 803、 基站 1将获取到的测量配置信息下发给 UE;
基站 1获取到来自基站 2的测量配置信息后， 可将该测量配置信息下发给 基站 1覆盖范围内的 UE, 使 UE可对基站 2下的小区进行测量或进行其它操作 处理。
由上可见， 本发明实施例中基站将其本地覆盖范围内的小区的测量配置信 息下发到网络中与其由接口连接的其它基站， 使得网络中的各个基站均可获知 其它基站覆盖范围下的小区的测量配置信息， 并可将其它基站覆盖范围下的小 区的测量配置信息下发给 UE, 使 UE可对其它基站下的小区进行测量或进行其 它操作处理。
