其中, 所述测量类型配置信息: CRS 限制性测量信息 (比如起始位置, 可以以
5ms为周期等); DRS的配置信息包括: 天线端口信息 (天线端口信息可以是天线数 和 /或天线端口号等); 频域资源配置信息; 码域资源配置信息; 子帧配置信息 (包括 子帧偏移信息和周期信息); 以及 UE假定的 PDSCH和 DRS的传输功率的比值。 还 可以包括; 被测量小区的同步信息, 如 SFN shift、 subframe shift禾口 /或 symbol shift。
另夕卜, DRS的配置可以是全集子帧或者是 DRS子帧的子集。 在被测小区有 ABS 配置时,第二通信节点可以取该测量配置集合和限制性测量下发的集合的交集进行测 量; 但并不限于此, 还可以包括其他方式, 本实施例不作限制。
关于测量信号类型的选择, 第一通信节点 (比如基站)可以根据特定场景下, 小 区的无线信号变化情况等, 来选择测量信号类型, 比如: 如果小区的无线信号变化比 较快,为了避免单独依赖 DRS测量造成的乒乓切换和过早切换,可以采用 CRS、DRS 混合测量; 或者 CSI-RS、 DRS混合测量; 或者 DRS、 CRS、 CSI-RS混合测量等。
比如, 第二通信节点 (比如 UE)首先通过测量 DRS获得相邻小区的初始值, 然 后通过对 CRS和 /或 CSI-RS的测量来满足后面的迟滞和 TTT的上报要求。
报告配置信息: 增加底层向高层上报的测量的周期值。 可选的, 该值需要考虑 DRS的精度和传输周期;
也就是说, 上述测量信号配置信息还可以包括被测小区的测量指示信息, 如 m-RSRP 测量指示信息和 /或 m-RSRQ 测量指示信息 (m可以是 CRS,CSI-RS,和 /或 DRS); 上述测量信号配置信息还可以包括测量上报方式指示信息, 用于指示第二通 信节点 (比如 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,则测量信号配置信息还可以包括 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 数等, 如层三平滑过滤等参数等。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 认预置在第二通信节点中, 本实施例不作限制。

其中, 所述 GAP的配置信息还可以包括以下至少一种: 每一套 GAP的配置信息 对应的测量信号的种类, 每一套 GAP的配置信息对应的频率和 /或系统的信息。
也就是说, 在上述实施例中, 特别是在异频测量的配置中引入一种新的 GAP配 置机制: GAP 的格式灵活, GAP 的格式可以和 DRS 的图样匹配; 如果某个小区的 DRS每 400ms为周期, 在第 0个无线帧的第 0个和第 1个出现 2次 DRS, 则配置给 UE 的 GAP格式为一个 2ms的 GAP,起始位置是每 400ms的第 0个无线帧的第 0个 子帧; 而且, 测量的周期需要考虑 DRS的精度和传输周期。 如果一个 DRS子帧就可 以满足测量精度, 则 GAP 的长度可以是一个子帧; 测量周期 1ms 即可; 如果三个 DRS子帧就可以满足测量精度, 而 6个子帧内分布了 3个 DRS子帧, 则 GAP的长 度可以是 1ms or 6ms, 但测量周期是 6ms;
或者, 在该实施例中, 第一通信节点 (比如基站) 给第二通信节点 (比如 UE) 配置多个 GAP图样组合; 或者,第一通信节点告知第二通信节点的多类 GAP的图样 组合: 比如, 基站告知 UE哪类 GAP是用来检测 SS的 GAP; 哪类 GAP是用来 DRS 的 GAP; 哪类 GAP是用来 CRS的 GAP; 哪类 GAP是用来 CSI-RS的 GAP等等。

步骤 402: 所述第二通信节点根据所述测量信息中测量信号配置信息确定该测量 信号配置信息对应的测量信号的资源, 并对所述资源对应的测量信号进行测量,得到 测量结果;
在该步骤中, 所述第二通信节点接收到测量信息后, 而可以根据该测量信息确 定需要测量的测量信号的资源, 比如位置或载波等, 然后, 对所述资源对应的测量信 号进行测量。 也就是说, 第二通信节点 (比如 UE) 在接收到第一通信节点 (比如基站或集成 了 UE功能的基站等)发送的测量信息后, 可根据测量信息中的测量配置信息中的被 测小区的 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-RS/DRS 配置信息的配置索引号等)的差异来区分相同物理小区标识指示的不同被测小区并进 行测量的操作。 第二通信节点可利用被测小区的信令配置信息对应的被测小区进行测量,获取该 被测小区的测量结果, 如被测小区的 DRS-RSRP和 /或 DRS-RSRQ等。 可选的, 第二 通信节点可以将测量结果和测量信号配置信息中的信号的配置信息、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,第二通信节点可周期性地 测量被测小区, 并上报被测小区的测量结果。 如果第二通信节点接收到的测量信息中包括测量指示信息,如 m-RSRP测量指示 信息和 /或 m-RSRQ测量指示信息等, 则第二通信节点可依据测量指示信息获取第一 通信节点所需要的测量值, 将该测量值作为测量结果上报给第一通信节点, 比如, 若 第一通信节点发送的测量信息中包括 D-RSRP测量指示信息,则第二通信节点获取被 测小区的 D-RSRP, 若第一通信节点发送的测量信息中包含 D-RSRQ测量指示信息, 则第二通信节点获取被测小区 D-RSRQ。 步骤 403 : 所述第二通信节点根据所述测量结果进行小区探测和 /或小区选择和 / 或小区重选和 /或 RLM。

所述第一通信节点控制的具体每个小区的 DRS的位置和图样是可配置的, 也就 是说, 可以根据实际需要灵活的配置各个小区的 DRS的位置和图样; 或者:
所述第一通信节点控制的具体每个小区的 DRS 资源被分成了两类: 一类是固定 子集, 每个小区的所述固定子集均相同; 一类是灵活子集, 每个小区的灵活子集均不 同。

另一实施例中, 第一通信节点控制的每个小区的 DRS的位置和图样 (position and pattern) 是固定的; 且, 不同小区可以不同; 另一实施例中, 第一通信节点控制的每个小区的 DRS的位置和图样 (包括单位 子帧上的 DRS分布图样, 以及子帧间的发射图样, 如周期是 400ms内哪些子帧上发 射 DRS,哪些不发送 DRS)是灵活的,可以配置;比如 the position of the subframe /PRB, DRS的发送周期, 图样, 以及在某个子帧上的密度等。
在该实施例中, 所述 DRS的资源可以是小区级, 也可以 UE级, 本实施例不作 限制。
另一实施例中, DRS 资源被分成了两类: 一类是固定子集, 每个小区都一样; 一类是灵活子集, 每个小区都不一样。
这是因为, 由于 UE最初的小区选择阶段, 因为没有先验信息, 就利用固定子集 的 DRS资源来进行小区发现和测量; UE在读取广播消息后,便可以利用固定子集和 灵活子集的资源来进行小区的测量和时频跟踪。
其中对本实施例只发送一种 DRS的信令, 以发送多种 DRS的信令的示意如图, 分别如图 5A和图 5B所示, 图 5A为本发明实施例中只发送 DRS的信令的示意图, 图 5B为本发明实施例中发送多种信令共存的示意图。

为了便于本领域技术人员的理解, 下面以具体的应用实例来说明。
应用实例一
还请参阅图 14, 为本发明实施例提供的一种测量方法的应用实例的流程图; 该 实施例中的增强小区可以是具有增强功能的小区, 或新类型载波上的小区, 或是新类 型载波等, 本实施例不作限制。 在该实施例中, 第一通信节点以基站, 第二通信节点 以 UE为例, 但并不限于此, 所述方法包括:
步骤 141 : 基站获取邻小区的 DRS的配置信息;
其中, 可以通过 X2 口, 或这两基站间的其他接口 (比如如无线接口等), 或这
OAM获得邻区的 DRS的配置信息, 其中, DRS的配置信息如上述所示, 在此不再 赘述。
具体的, 在基站间的接口建立时, 所述基站通过接收相邻基站发送的所述相邻基 站的指定载波的载波类型, 与相邻基站交互各自基站下小区的小区信息, 包括: 小区 的载波频段、 载波类型、 小区 ID ( identity, 标识)、 测量信令的配置等信息。
下面以基站 1和基站 2通过 X2接口建立连接为例来说明。
基站 2在向基站 1发送的 X2接口建立请求 ( X2 setup request) 消息, 所述请求 消息中携带基站 2下的小区及相邻小区的小区信息;
基站 1在向基站 2发送的 X2接口建立响应(X2 setup response)消息, 所述响应 消息中携带基站 1下的小区及相邻小区的小区信息。
另一方面, 当基站 1和基站 2通过 S 1接口建立连接时, 可以通过移动管理实体 (MME, mobility management entity) 进行信令交互, 以使得基站 1和基站 2获取各 自基站以及相邻基站下各小区的小区信息。
其中步骤 141为可选步骤。
步骤 142: 基站确定 UE的测量信息, 所述测量信息可以包括该 UE的服务小区 信息和相邻的同频, 异频的小区的信息, 比如包括, 小区所在载波的类型 (普通载波 或新载波类型的载波;), 测量信息 (包括测量配置信息) 等。
本发明实施例中的所述普通载波为传统的后向兼容载波,所述新类型载波为增强 型的非后向兼容载波, 可以为在 Release-11版本里 3GPP提出的一种新的载波类型一 新载波类型 NCT。 NCT被考虑作为一种非后向兼容的载波, 可以通过修改现有的机 制以增强载波性能, 例如: 增强频谱效率、 提高异构网络支持、 节能等。
为了实现上述性能的提升,本发明实施例提供给 UE的测量信息可以包括: DRS , 用于小区发现和 /或测量; SS (包括 PSS/SSS), 用于小区发现, 该信令可选; CSI-RS, 主要用于 CSI值的上报; 以便于 UE利用以上的信息来进行小区发现和 /或测量。
步骤 143 : 所述基站向用户终端下发测量信息, 以指示所述用户终端对指定的小 区进行测量。 本发明实施例中可以由基站通过无线资源控制 (RRC, radio resource control) 消 息向用户设备下发测量任务 (即测量信息), 但不仅限于此。
每个测量任务包括: 测量实体信息(measurement object)和报告配置信息(report configuration),测量实体信息用于指示需要 UE进行测量的指定小区 /载波; 报告配置 信息用于确定触发 UE向基站发送测量报告的配置信息。其中, 测量实体信息和报告 配置信息是测量任务中的信元消息,基站可以优选的将参考信号指示信息携带于测量 实体信息中, 也可以携带于报告配置信息中, 此处不做限定。
测量实体信息中包括以下至少一种组合: 相邻小区标识, 测量类型配置信息, 测 量信令配置信息和报告配置信息。
基站发送给 UE的传统的小区配置是基于 CRS/CSI-RS的传统测量配置; 基站给 增强的小区配置新型的测量方式。
其中,相邻小区标识 (如果是 RLM测量或 CSI上报测量,则不需要): PCI, DRS (集) 标识, CSI-RS(集)标识中的至少一项的组合。
新型的测量方式:如果测量任务中包括 RRM测量,则是 UE利用 DRS进行测量; 如果测量任务中包括 CSI上报的测量, 则是 UE利用 CSI-RS进行测量; 如果测量任 务中包括 RLM测量, 则 UE利用 DRS或 CSI-RS进行测量。
测量信令配置信息: DRS的配置信息, DRS的配置信息包括: 天线端口信息(天 线端口信息可以是天线数和 /或天线端口号);频域资源配置信息;码域资源配置信息; 子帧配置信息 (包括子帧偏移信息和周期信息); 以及 UE假定的 PDSCH和 DRS的 传输功率的比值。 所述测量信息中还可以包括; 被测量小区的同步信息, 如 SFN shift/subframe shift/symbol shift等。 另夕卜, DRS的配置可以是全集子帧或者是 DRS 子帧的子集。在被测小区有 ABS配置时, UE可以取该测量配置集合和限制性测量下 发的集合的交集进行测量。
报告配置信息: 增加底层向高层上报的测量的周期值。 可选的, 该值需要考虑 DRS的精度和传输周期, 如图 15所示, 图 15为本发明实施例提供的一种上报测量 周期值的示意图。
如图 15所示, 小区 1和小区 2发送 DRS信号和 SS (同步信号), 小区 1的 DRS 的单位子帧上的信号密度较大, 1个子帧的测量即可以满足测量精度, 所以, 测量上 报给高层的周期是 3ms; 而小区 2的 DRS的单位子帧上的信号密度较小, 2个子帧 的测量才可以满足测量精度, 所以, 测量上报给高层的周期是 4ms; 小区 3和小区 4 发送 DRS信号也具有同步信号的功能,小区 3的 DRS的单位子帧上的信号密度较大, 1个子帧的测量即可以满足测量精度, 所以, 测量上报给高层的周期是 lms; 而小区 4的 DRS的单位子帧上的信号密度较小, 2个子帧的测量才可以满足测量精度, 所 以, 测量上报给高层的周期是 2ms。
在该实施例中, 上述测量配置消息还可以包括被测小区的测量指示信息, 如 m-RSRP测量指示信息和 /或 m-RSRQ测量指示信息 (m可以是 CRS, CSI-RS, 禾口 / 或 DRS); 上述测量配置消息还可以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, 则测量信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,本实施例不作限定。
步骤 144、 UE根据接收到的测量信息对被测小区对应的配置的信号进行测量, 获取测量结果; 并将所述测量结果上报基站;
UE在接收到基站发送的测量信息后, 可根据测量信息中的被测小区的 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-RS/DRS 配置信息的配置 索引号等) 的差异来区分相同物理小区标识指示的不同被测小区并进行测量的操作。 UE可利用被测小区的信令配置信息对相应的被测小区进行测量, 获取该被测小区的 测量结果, 如被测小区的 DRS-RSRP禾 P/或 DRS-RSRQ等。 进一步, UE还可以将测 量结果和测量配置消息中的信令的配置信息、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可以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 m-RSRP 测量指示信息和 /或 m-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,若基站发送测量信息中包含 D-RSRP测量指 示信息,则 UE获取被测小区的 D-RSRP,若测量信息中包含 D-RSRQ测量指示信息, 则 UE获取被测小区 D-RSRQ。
步骤 145: 所述基站接收所述用户设备上报的测量报告, 所述测量报告中包括所 述用户设备根据所述测量任务测量所述指定小区 /载波得到的测量结果, 根据所述测 量报告对所述 UE进行管理。
基站在获取测量报告后, 能够根据测量结果确定指定小区 /载波的信号质量和信 号强度, 从而便于基站对用户终端和该指定小区 /载波进行管理, 例如: 基站决定是 否为该用户终端增加新的载波, 增加 COMP集合中的小区或者对该指定小区 /载波进 行维护, 或者是决定小区间切换的场景等。
或者,基站在获取测量报告后,能够根据测量结果确定 UE在服务小区 /载波(集) 的信号质量, 从而便于基站对用户终端的调度机制的确定。
