Description

载波聚合中的测量方法及用户设备 技术领域 本发明涉及通信领域， 具体而言， 涉及一种载波聚合中的测量方法及用 户设备。 背景技术 在移动通信系统中，为了满足移动性要求，当用户设备（ User Equipment, 简称 UE )在某个小区与网络建立连接之后， UE仍然需要对其服务小区和相 邻小区的信号质量进行测量， 以便选择合适的小区进行切换。 以演进型全球 陆地无线接入网络 ( Evolved Universal Terrestrial Radio Access Network, 简称 为 EUTRAN )为例， 连接态下 UE测量的具体过程是： 网络侧将测量控制消 息发送给 UE, 其中，该测量控制消息中包括测量标识（ measurement identity, 简称为 MID )、 事件类型、 测量对象、 以及需要测量的属性； UE根据测量控 制消息中的测量标识进行参数初始化， 并获取测量控制消息中的全部测量对 象中的每个测量对象各自的属性和测量结果； UE 才艮据初始化的参数或预定 门限值对每个测量对象的测量结果进行事件评估， 并通过评估确定全部测量 对象中满足测量事件的进入条件的持续时间大于或等于预定测量触发时间长 度（ Time To Trigger, 简称为 TTT ) 的测量对象； UE将这些满足事件进入条 件的测量对象 （此时测量对象已经对应为小区）放入该事件对应的测量标识 的小区列表（ cells Triggered List ) 中； UE根据确定的测量对象的测量结果生 成测量报告并将测量报告发送至网络侧， 测量报告中所包含的测量对象都是 从该事件对应的测量标识的小区列表中获取的。 为了满足人们对更高带宽的需求， LTE Advance提出釆用载波聚合的方 法实现更大带宽的目的， 此时一个小区由多个连续或不连续的载波（各个载 波称为分量载波， Component Carrier ) 组成， 能够同时为 UE提供多载波的 艮务。分量载波可以釆用兼容 LTE系统的载波，这种载波称为后向兼容载波； 分量载波也可以釆用不兼容现有 LTE系统的载波， 这种载波称为非后向兼容 载波， 这种载波只能为 Release 10版本及以上的 UE使用。 对于连接态的用 户设备， 其工作的多个分量载波称为激活载波集、 或调度载波集、 或服务载 波集， 根据上下行可以分为 UE的上行载波集和 UE的下行载波集。 在 UE 的下行载波集中， 还可以分为物理下行控制信道 （Physical downlink control channel, 简称为 PDCCH ) 载波集和物理下行共享信道 （Physical downlink shared channel, 简称为 PDSCH ) 载波集， 某些载波可能只提供 PDSCH。 在 LTE 中， UE 只能工作在一个载波上， 这个载波称为服务小区， 在 LTE Advance中， 工作的多个分量载波包含一个或一个以上的月艮务小区， 如 果工作的分量载波只有一个服务小区， UE只接收服务小区的系统消息， UE 视其他的载波均为资源； 如果工作的分量载波包含一个以上的服务小区， UE 需要同时接收这几个服务小区的系统消息， 这几个服务小区具有独立性。 载波聚合按各分量载波在频域上是否连续，可以分连续的载波聚合和非 连续的载波聚合， 所谓连续的载波聚合是指各分量载波在频域上是相互连接 的； 而非连续的载波聚合则指各个分量载波之间在频域上是不连接的。 载波 聚合按各分量载波是否在同一频带内， 可以分为单频带 （single band ) 的载 波聚合和跨频带（ over multiple frequency bands )的载波聚合， 所谓单频带的 载波聚合是指参与载波聚合的所有分量载波都在同一个频带内， 单频带的载 波聚合可以是连续的载波聚合也可以是非连续的载波聚合； 所谓跨频带的载 波聚合是指参与载波聚合的分量载波可以源自不同的频带。 在载波聚合中网络才艮据 UE发送的测量 4艮告为 UE 配置工作的多个载 波。 在现有的测量配置中， 网络按照各个频点分别为 UE配置测量任务， UE 分别评估各个频点上满足上报条件 （对于测量事件， 指满足测量事件的进入 条件的时间大于或等于 TTT; 对于周期性测量， 指满足测量上报构造条件） 的小区， UE 发送测量报告给网络侧。 由于不同频点的测量配置可能不同如 TTT不同， 各个频点测量事件的进入条件也可能不同， 导致 UE发送不同频 点的测量报告的时间是不同的， 即网络侧不能同时获得不同频点分量载波的 测量报告， 这对网络侧对该 UE管理不同的分量载波是不利的。 网络侧需要 根据 UE的测量报告动态的增加或删除分量载波， 如果网络侧一次只能获得 一个分量载波所在频点的测量报告， 网络侧一次只能动态的修改这个频点上 分量载波的配置（增加或删除）， 釆用这种方法网络需要耗费大量的空口信令 才能实现载波的管理。 为了实现网络侧能够更加有效的管理不同分量载波的 目的， 需要釆用新的测量配置。 针对相关技术中现有的协议中网络侧不能同时获得不同分量载波测量 报告以及无法根据现有的测量报告对不同分量载波进行管理的问题， 目前尚 未提出有效的解决方案。 发明内容 针对现有的协议中网络侧不能同时获得不同分量载波测量 4艮告以及无 法根据现有的测量报告对不同分量载波进行管理的问题而提出本发明，为此， 本发明的主要目的在于提供一种载波聚合中的测量方法及用户设备， 以解决 上述问题。 为了实现上述目的， 根据本发明的一个方面， 提供了一种载波聚合中的 测量方法。 根据本发明的载波聚合中的测量方法包括： 用户设备接收到测量配置， 其中， 测量配置中包括应用于一个或多个分量载波的测量事件； 用户设备根 据测量配置执行测量。 优选地， 测量事件包括以下至少之一： 与预定门限比较的测量事件、 多 个分量载波之间的比较事件。 优选地， 与预定门限比较的测量事件包括： 分量载波的信号质量超过预 定门限的事件或分量载波的信号质量低于预定门限的事件。 优选地， 多个分量载波之间的比较事件包括以下之一： 非激活分量载波 与服务小区比较的事件； 一个或多个分量载波与服务小区比较的事件； 最好 的分量载波改变的事件； 非激活分量载波与激活的分量载波比较的事件； 激 活的分量载波中信号顺序改变的事件；多个分量载波中信号顺序改变的事件； 服务小区之间比较的事件。 优选地，多个分量载波中的每一个分量载波均为用户设备所在的载波聚 合小区的分量载波或均为用户设备提供资源的分量载波。 优选地， 一个或多个分量载波釆用信令指示或默认配置。 优选地， 一个或多个分量载波釆用信令指示包括： 测量配置中包括一个 或多个分量载波的信息。 优选地， 一个或多个分量载波的信息包括以下之一： 分量载波的频率； 分量载波的索引； 分量载波的物理层标识 （Physical Cell Identifier, 简称为 PCI ); 分量载波的全局小区标识 （ Cell Global Identifier, 简称为 CGI )。 优选地， 当一个或多个分量载波为以下之一时，一个或多个分量载波釆 用默认配置： 载波聚合小区中的服务小区； 载波聚合小区中所有的分量载波； 载波聚合小区中除服务小区之外的分量载波； 载波聚合小区中用户设备的激 活载波之外的分量载波； 载波聚合小区中用户设备的激活载波； 载波聚合小 区中除扩展载波之外的分量载波； 载波聚合小区中除服务小区和扩展载波之 外的分量载波。 优选地， 在用户设备根据测量配置执行测量之后， 上述方法还包括： 用 户设备生成测量报告， 向网络侧发送测量报告。 优选地， 测量配置中携带有测量事件对应的测量标识。 优选地， 服务小区是指为用户设备提供系统消息、 寻呼消息、 安全输入 参数的分量载波。 为了实现上述目的， 根据本发明的另一方面， 提供了一种用户设备。 根据本发明的用户设备包括： 接收模块， 用于接收测量配置， 其中， 测 量配置中包括应用于一个或多个分量载波的测量事件； 测量模块， 用于根据 测量配置执行测量。 优选地， 用户设备还包括： 生成模块， 用于生成测量 4艮告； 发送模块， 用于向网络侧发送测量报告。 优选地， 测量事件包括以下至少之一： 与预定门限比较的测量事件、 多 个分量载波之间的比较事件。 通过本发明， 釆用用户设备接收测量配置， 其中， 测量配置中包括应用 于一个或多个分量载波的测量事件； 用户设备根据测量配置执行测量， 解决 了现有的协议中网络侧不能同时获得不同分量载波测量报告以及无法根据现 有的测量报告对不同分量载波进行管理的问题， 进而达到了使 UE可以同时 上报分量载波的测量结果，从而使网络侧能够更好的管理分量载波以及为 UE 调度合适的分量载波的效果。 附图说明 此处所说明的附图用来提供对本发明的进一步理解，构成本申请的一部 分， 本发明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的 不当限定。 在附图中: 图 1是根据本发明实施例的 LTE Advance系统的网络布局示意图； 图 2是^ f艮据本发明实施例的载波聚合中的测量方法的流程图； 图 3是根据本发明实施例的用户设备的示意图； 图 4是根据本发明优选实施例的用户设备的示意图。 具体实施方式 考虑到现有的协议中网络侧不能同时获得不同分量载波测量 4艮告以及 无法根据现有的测量报告对不同分量载波进行管理的问题， 本发明实施例提 供了一种载波聚合中的测量方法及用户设备。 该方法包括： 用户设备接收测 量配置， 其中， 测量配置中包括应用于一个或多个分量载波的测量事件； 用 户设备根据测量配置执行测量。 需要说明的是， 在不冲突的情况下， 本申请中的实施例及实施例中的特 征可以相互组合。 下面将参考附图并结合实施例来详细说明本发明。 根据本发明的实施例， 提供了一种载波聚合中的测量方法。 如图 2所示， 该方法包括如下的步 4聚 S202至步 4聚 S204： 步骤 S202, 用户设备接收到测量配置， 其中， 测量配置中包括应用于 一个或多个分量载波的测量事件； 步骤 S204 , 用户设备根据测量配置执行测量。 优选地， 在用户设备根据测量配置执行测量之后生成测量报告。 优选地， 测量 4艮告为测量事件对应测量标识的测量 4艮告。 优选地， 该方法还包括： 用户设备向网络侧上报测量报告。 优选地， 上述测量事件包括与预定门限比较的测量事件、 或多个分量载 波之间的比较事件。 优选地， 与预定门限比较的测量事件包括： 分量载波的信号质量超过预 定门限、 或分量载波的信号质量低于预定门限。 优选地， 多个分量载波之间的比较事件包括以下之一： 非激活分量载波 与服务小区比较的事件、 一个或多个分量载波与服务小区比较的事件、 最好 的分量载波改变的事件、 非激活分量载波与激活的分量载波比较的事件、 激 活的分量载波中信号顺序改变的事件、多个分量载波中信号顺序改变的事件； 服务小区之间比较的事件。 优选地， 如果 UE有多个服务小区， 分量载波之间的比较事件还包括服 务小区之间比较的事件。 优选地， 所述最好的分量载波是指信号质量最好的分量载波。 优选地， 上述分量载波是 UE 所在的载波聚合小区的分量载波， 即与

UE收到测量配置后， 评估一个或多个分量载波。 优选地，多个分量载波中的每一个分量载波均为用户设备所在的载波聚 合小区的分量载波、 或为用户设备提供资源的分量载波； 所述服务小区是指 为用户设备提供系统消息、 寻呼消息、 安全输入参数等功能的分量载波。 优选地， 一个或多个分量载波釆用信令指示（由网络侧指定）或釆用默 认配置 （默认设置）。 优选地， 一个或多个分量载波釆用信令指示包括： 测量配置中包括一个 或多个分量载波的信息。 优选地， 一个或多个分量载波的信息包括以下之一： 分量载波的频率； 分量载波的索引； 分量载波的 PCI; 分量载波的 CGI。 由网络侧指定是指测量配置中包含分量载波的信息， 可以是频率信息、 分量载波索引 （carrier index )、 分量载波的物理层标识、 或分量载波的全局 性标识。 优选地， 釆用默认配置 （默认设置） 是指载波聚合小区中的服务小区、 或载波聚合小区中所有的分量载波、 或载波聚合小区中除服务小区之外的分 量载波、 或载波聚合小区中该 UE的除激活载波之外的分量载波、 或载波聚 合小区中该 UE的激活载波、 或所述载波聚合小区中除扩展载波之外的分量 载波、 或所述载波聚合小区中除服务小区和扩展载波之外的分量载波。 优选地， UE探测到一个或多个分量载波在持续 TTT均满足测量事件的 进入条件， UE触发测量报告。 优选地， UE探测到一个或多个分量载波， 是指一个或多个分量载波不 在小区列表中。 优选地， 测量配置携带应用于测量事件的标识， 当标识有效设置时， 如 果在小区列表中存在持续 TTT满足离开条件的分量载波，UE触发测量报告。 优选地， 在用户设备根据测量配置执行测量之后， 上述方法还包括： 用 户设备生成测量报告， 向网络侧发送测量报告。 优选地， 测量配置中携带有测量事件对应的测量标识。 下面将结合实例对本发明实施例的实现过程进行详细描述。 为了说明本发明的实施例， 首先进行如下描述： 在移动通信系统中， 测量对象以频率或位于频率的小区集为单位， 测量 配置包括测量标识、 测量对象、 测量上 4艮的形式 （例如， 事件触发或周期上 4艮） 等， 其中， 测量标识对应于某一测量对象 （ measurement object ) 与特定 的测量上报构造（ reporting configuration , 简写为 RC , 表示上报的属性）， 同 一测量对象的不同测量上 4艮构造对应不同的测量标识。 对于事件类型的测量 配置， 测量上 ~¾构造与测量事件——对应 （此时一个测量标识描述了一个测 量对象以及与之对应的测量事件；)，目前定义的测量事件一般包括事件的进入 条件、 离开条件、 事件的特定门限 Thresh、 事件的滞后参数 Hys、 事件的进 入条件的持续时间以及事件的偏移量 Offset等。 为了满足连接态下 UE的移动性要求， 要求 UE对服务小区和邻小区进 行测量并上报满足事件进入条件的测量对象， 目前已经定义了一些对服务小 区的测量事件， 例如， 定义测量事件的进入条件为服务小区的信号质量高于 预定门限， 或服务小区的信号质量低于预定门限； 对邻小区的测量事件， 例 如， 定义测量事件的进入条件为邻小区的信号质量高于某一门限值， 或邻小 区的信号质量比当前服务小区的信号质量高预定的偏移量。 对于事件触发的测量报告， 有两种上报形式： 一种是事件触发单次上报 (或称为事件触发的测量报告）； 另一种是事件触发周期性上报。 事件触发单 次上报是指网络侧为某个 UE配置了事件的进入条件， UE检测并评估测量对 象满足事件的进入条件后， 将满足事件进入条件的测量对象放入该事件对应 的测量标识的小区列表中， 只上报一次测量报告， 该报告包含的测量对象均 是从 'J、区列表获取的。 如果在后面的某个时间， 又有新的测量对象满足该事 件的进入条件， UE 将新的测量对象放入该事件对应的测量标识的小区列表 中， 同时再次上报新的测量报告， 新的测量报告包含的测量对象均是从此时 小区列表获取的， 此时上报次数仍为一次。 事件触发周期性上 4艮是指网络侧为某个 UE配置了事件的进入条件， UE 检测并评估测量对象满足事件的进入条件后， 将满足事件进入条件的测量对 象放入该事件对应的测量标识的小区列表中， 多次上报测量报告， 上报的次 数和时间间隔均由网络侧配置， 每次上报的测量报告包含的测量对象均是从 当前上报时的小区列表中获取的。 在这多次上报的过程中或者多次上报结束 后， 如果有新的测量对象满足事件的进入条件， UE 将重置上报次数， 将新 的测量对象放入该事件对应的测量标识的小区列表中， 然后依照设定的时间 间隔和上报次数再次有序的上报测量结果， 每次测量报告包含的测量对象均 是从当前上报时的小区列表中获取的。 对测量对象的测量， 不同的系统釆用不同的测量方法， 均是反映小区的 信号质量。在 LTE中，UE测量的是接收到的参考信号的功率（Reference Signal Received Power, 简称为 RSRP, 单位为 dBm )或 UE接收到的参考信号的质 量（ Reference Signal Received Quality,简称为 RSRQ,单位为 dB )。在 WCDMA 中， UE测量的是公共导频信道的接收功率（ Received Signal Code Power, 简 称 RSCP, 单位为 dBm ) 或公共导频信道的 Ec/No (指发射端扩谱后每码道 上每个码片的能量和带限白噪声功率谱密度的比）， 单位是 dB。 UE 在比较 不同小区的信号质量时需要比较同一类型的测量结果。 在评估测量对象满足 事件进入条件时， 对该测量对象的完整描述不仅包括 UE 测得的 RSRP 或 RSRQ, 还包括该测量对象的频率特定的偏移量 （frequency specific offset, 简称 Ofn )、 小区特定的偏移量（ cell specific offset, 简称 Ocn ), 以 LTE中定 义的 A4事件为例： 进入条件为邻小区的信号质量高于某一门限值， 其具体 的数学描述为 Mn+Ofii+Ocn-Hys>Thresh,式中 Mn为 UE测得邻小区的 RSRP 或 RSRQ„ 图 1是根据本发明实施例的 LTE Advance系统的网络布局示意图。 实施例一 在 LTE Advance系统中， 釆用如图 1所示的网络架构。基站 1所辖小区 1 是载波聚合的小区 （在本发明中， 载波聚合小区是指具有载波聚合功能的 小区， 即一个小区由多个分量载波组成）， UE在小区 1中处于空闲状态。 这 里， 基站 1即： 泛指图 1中的任何一个 eNB。 以下涉及到的基站 1也是这里 的意思， 以下不作赞述。 eNB与核心网络之间的接口为 S 1接口， 其中， eNB 与核心网之间的接口可以分为两个部分， 一部分用于完成移动性管理和 S 1 接口的控制面功能； 另一部分用于完成用户数据的路由、 传递等功能。 eNB 之间通过 X2接口相连， X2接口用于完成用户设备在激活状态下的移动性管 理功能以及对等的 eNB之间的信息交互。该载波聚合的小区包含的分量载波 在频带 1 , 即 Band 1中，下行有 3个连续的分量载波， 即： CC ( fl )、 CC ( f2 )、 CC ( β ); 上行也是 3 个连续的载波， 即： CC ( f4 )、 CC ( f5 )、 CC ( f6 )。 三个下行载波均发送系统消息、 寻呼消息。 某个时刻， UE在分量载波（ UL CC ( f4 ), DL CC ( fl ) )发起随机接入， 成功接入该载波聚合的小区。 在本实施例中， UE 只有一个月艮务小区， 如果 UE需要接入更多的载波， UE视其他载波为资源载波。 此时 UE视当前的分 量载波（UL CC ( f4 ), DL CC ( fl ) ) 为服务小区。 需要说明的是， 为 UE提 供资源的分量载波与月艮务小区存在本质的区别， 在 LTE系统， 连接态的 UE 只有一个服务小区， 该服务小区为 UE提供系统消息、 寻呼消息、 安全输入 参数等； 引入载波聚合后， UE的服务小区提供同样的功能， 即为 UE提供系 统消息、 寻呼消息、 安全输入参数等。 而为 UE提供资源的分量载波， 不提 供这些功能， 这些分量载波只是为了提高传输的带宽。 为了实现移动性以及分量载波的管理， 基站 1向 UE发送测量配置， 在 测量配置中包含现有协议中的测量任务如： 测量标识 1 , 该测量标识对应的测量对象（ fl )以及测量事件 A1 (即测 量上报构造 RC ), 测量事件 A1为服务小区的信号超过预定门限， 测量标识 1包含预定门限的值、 滞后参数 Hys、 TTT、 fl的频率偏移量 offsetFreq等； 测量标识 2 , 该测量标识对应的测量对象（ fl ) 以及测量事件 A3 , 测量 事件 A3 为邻区的信号质量比服务小区的信号质量高预定的偏移量， 测量标 识 2包含预定的偏移量、 滞后参数 Hys、 TTT、 服务小区特定的偏移量 Ocs、 邻区特定的偏移量 Ocn、 fl的频率偏移量等； 测量标识 3 , 该测量标识对应的测量对象（ f2 )以及测量事件 A3 , 测量 事件 A3 为邻区的信号质量比服务小区的信号质量高预定的偏移量， 测量标 识 3包含预定的偏移量、 滞后参数 Hys、 TTT、 服务小区特定的偏移量 Ocs、 邻区特定的偏移量 Ocn、 f2的频率偏移量等； 测量标识 4, 该测量标识对应的测量对象（ β )以及测量事件 Α4, 测量 事件 Α4为邻区的信号质量高于预定门限， 测量标识 4包含预定门限、 滞后 参数 Hys、 TTT、 邻区特定的偏移量 Ocn、 β的频率偏移量等。 为了实现本发明， 基站向 UE发送的测量配置还包括新的测量标识： 测量标识 5 ,该测量标识对应的测量对象为分量载波（ CC( fl )、 CC( f2 )、 CC ( β ), 可以用分量载波的标识表示如分量载波索引 （ carrier index )、 分量 载波的物理层标识、 或分量载波的全局性标识）、 或多个频点 （fl、 f2、 以及 β )、 或该载波聚合小区 （小区 1 )。 该标识对应的测量事件 Α6 (可以釆用其 他的 Α7或 Α8标识）为分量载波的信号质量超过预定门限， 此处特指该载波 聚合小区的分量载波的信号质量超过预定门限。测量标识 5还包括预定门限、 滞后参数 Hys、 TTT、 各频率的偏移量等。 优选地， 新增的测量事件应用的 分量载波是指 UE所在的小区 1的部分或全部分量载波， 即与 UE保持连接 的具有载波聚合功能的小区 1的部分或全部分量载波。
UE收到测量配置后， 对其中的测量标识进行参数初始化， 并获取测量 配置中的全部测量对象中的每个测量对象各自的属性和测量结果； UE 根据 初始化的参数或预定门限值对每个测量对象的测量结果进行事件评估。 在本 实施例中， 由于有新的测量标识 5对应的测量对象为分量载波或多个频点或 该载波聚合小区， UE初始化 CC ( fl )、 CC ( f2 )、 CC ( β )对应的参数， 评 估满足测量事件 Α6 进入条件的分量载波， 如果有经过层 3 平滑处理 （L3 filtering ) 的一个或多个分量载波满足测量事件 A6的进入条件的持续时间大 于或等于预定测量触发时间长度 TTT, UE生成测量报告， 将满足条件的分 量载波上报网络侧， 网络侧据此可以有效地管理分量载波。 在某个时刻， UE发现分量载波 CC ( fl ) 和 CC ( f2 )在 ΤΤΤ时间内均 满足事件 A6的进入条件， 即分量载波 CC ( η ) 和 CC ( f2 ) 的信号质量均 高于预定门限， CC ( fl ) 和 CC ( f2 ) 的信号质量的测量结果已经经过层 3 的平滑处理 （ filtering ), UE将分量载波 CC ( fl ) 和 CC ( f2 )放入测量标识 5对应的小区列表 cellsTriggeredList (或称为分量载波列表）。 UE生成测量标 识 5的测量报告 （该测量报告所包含的测量对象都是从测量标识 5的小区列 表中获取的， 其他的实施例与此相同）， 该报告包含分量载波 CC ( fl )和 CC ( f2 )的标识（可以是频率、 或者是分量载波的索引 Carrier Index、 或者是分 量载波的物理层标识 PCI或全局性标识 CGI )。 基站 1 收到测量报告后， 根 据 UE的业务需要、分量载波的负荷情况等做出为 UE增加工作载波 CC ( f2 ) 的决策。 基站 1通过专用信令向 UE发送增加工作载波 CC ( f2 )的信息， UE 收到该专用信令后， 同时利用两个分量载波与基站 1保持通信， 实现了大带 宽的需求。 测量标识 5对应的小区列表 cellsTriggeredList包含了 CC ( fl )和 CC ( f2 ) 后， 如果 CC ( fl ) 和 CC ( f2 ) —直满足进入条件， UE不会再次 触发测量报告； 如果 CC ( fl ) 或 CC ( f2 )持续 ΤΤΤ满足离开条件， 从小 区列表中删除后， CC ( fl ) 或 CC ( f2 ) 再次持续 TTT 满足进入条件， UE 才触发测量 4艮告， 这部分处理方法与现有协议保持一致。 在本实施例中， 釆用 A6标识的新的测量事件为分量载波（下行） 的信 号质量高于预定门限， 其进入条件 （或触发条件） 用表达式表示为： Mc+Ofc+Occ-Hys>Thresh ； 其 离 开 条 件 用 表 达 式 表 示 为 ： Mc+Ofc+Occ+Hy s<Thresh , 在上述表达式中， Mc 表示分量载波的测量结果 ( the measurement result of the component carrier ), Ofc表示分量载波的频率 特定的偏移量 ( the frequency specific offset of the frequency of the component carrier ), Occ表示分量载波的小区特定偏移量 （the cell specific offset of the component carrier ), Hys表示滞后参数， Thresh表示预定门限。 此处如果 Ofc 和 /或 Occ取零， 表达式可以简化。 需要说明的是， 本实施例新增的测量事件 中的分量载波包括服务小区对应的分量载波 CC ( fl ); 也可以不包括服务小 区对应的分量载波， 即仅适用于 CC ( f2 )和 CC ( β ), 基站 1在测量配置中 指明适用的分量载波信息。 在本实施例中， 测量标识 5对应的测量对象釆用 明确的信令指示， 也可以釆用默认的配置： 如默认该载波聚合小区的所有分 量载波或除服务小区之外的分量载波。 在现有的协议中， 测量对象是单个频 率， 在本实施例中， 需要扩展测量对象的范围使其包含多个频率。 需要说明的是， 载波聚合的小区可以使用不对称的上下行载波， 比如下 行 5个载波， 上行 3个载波， UE也可以使用不对称的上下行载波。 载波聚 合小区也可以使用不连续的上下行载波（下行载波不连续，上行载波不连续）， UE 也可以使用不连续的上下行载波。 本实施例所述方法同样适用于这些场 景， 此处不再赘述。 实施例二 在 LTE Advance系统中， 釆用如图 1所示的网络架构。基站 1所辖小区 1是载波聚合的小区， UE在小区 1中处于空闲状态。 这里， 基站 1即： 泛指 图 1中的任何一个 eNB。该载波聚合的小区包含的分量载波在频带 1,即 Band 1中， 下行有 4个连续的分量载波， 即： CC (fl)、 CC (f2)、 CC (fi)、 CC (f4); 上行也是 4个连续的载波， 即： CC (f5)、 CC (f6)、 CC ( f7 )、 CC ( f8 )。 四个下行载波均发送系统消息、 寻呼消息。 某个时刻， UE在分量载波（ UL CC ( f5 ), DL CC ( fl ) )发起随机接入， 成功接入该载波聚合的小区。 在本实施例中， UE 只有一个月艮务小区， 如果 UE需要接入更多的载波， UE视其他载波为资源载波。 此时 UE视当前的分 量载波 （ULCC (f4), DL CC ( fl ) ) 为服务小区。 为了实现移动性以及分量载波的管理， 基站 1向 UE发送测量配置， 在 测量配置中包含现有协议中的测量任务， 内容与实施例一所述类似。 为了实现本发明， 基站向 UE发送的测量配置还包括新的测量标识： 测量标识 1,该测量标识对应的测量对象为分量载波（ CC( fl )、 CC( f2 )、 CC (fi)、 CC (f4), 可以用分量载波的标识表示如载波索引）、 或多个频点 (fl、 f2、 β、 f4)、 或该载波聚合小区 （小区 1 )。 该标识对应的测量事件 A6 (可以釆用其他的 A7或 A8标识）为分量载波的信号质量氏于预定门限， 此处特指该载波聚合小区的分量载波的信号质量低于预定门限。 测量标识 1 还包括预定门限、 滞后参数 Hys、 TTT、 各分量载波或各分量载波频率的偏 移量等。
UE收到测量配置后， 对其中的测量标识进行参数初始化， 并获取测量 配置中的全部测量对象中的每个测量对象各自的属性和测量结果； UE 根据 初始化的参数或预定门限值对每个测量对象的测量结果进行事件评估。 在本 实施例中， 由于有新的测量标识 1对应的测量对象为分量载波或多个频点或 该载波聚合小区， UE初始化 CC ( fl )、 CC ( f2 )、 CC ( β )、 CC ( f4 )对应 的参数， 评估满足测量事件 A6进入条件的分量载波， 如果有经过层 3平滑 处理（ L3 filtering )的一个或多个分量载波满足测量事件 A6的进入条件的持 续时间大于或等于预定测量触发时间长度 TTT, UE生成测量报告， 将满足 条件的分量载波上 ·ί艮网络侧， 网络侧据此可以有效地管理分量载波。 在某个时刻， UE发现分量载波 CC ( f2 ) 和 CC ( β )在 ΤΤΤ时间内均 满足事件 Α6的进入条件， 即分量载波 CC ( f2 ) 和 CC ( β ) 的信号质量均 低于预定门限， CC ( f2 ) 和 CC ( β ) 的信号质量的测量结果已经经过层 3 的平滑处理 （ filtering ), UE将分量载波 CC ( f2 ) 和 CC ( β )放入测量标识 1对应的小区列表 cellsTriggeredList。 UE生成测量标识 1的测量 4艮告， 该 4艮 告包含分量载波 CC ( f2 ) 和 CC ( β ) 的标识 （可以是频率、 或者是分量载 波的索引 Carrier Index, 或者是分量载波的物理层标识 PCI 或全局性标识 CGI )、以及信号质量的测量结果 RSRP和 /或 RSRQ。基站 1收到测量报告后， 获知分量载波 CC ( f2 ) 和 CC ( β ) 的信号质量不好， 不能增加这两个分量 载波为该 UE的激活载波。 在本实施例中， 釆用 Α6标识的新的测量事件为分量载波（下行） 的信 号质量低于预定门限， 其进入条件或触发条件用表达式表示为： Mc+Ofc+Occ+Hys<Thresh ； 其 离 开 条 件 用 表 达 式 表 示 为 ： Mc+Ofc+Occ-Hys>Thresh , 在上述表达式中， Mc 表示分量载波的测量结果 ( the measurement result of the component carrier ), Ofc表示分量载波的频率 特定的偏移量 ( the frequency specific offset of the frequency of the component carrier ), Occ表示分量载波的小区特定偏移量 （the cell specific offset of the component carrier ), Hys表示滞后参数， Thresh表示预定门限。 此处如果 Ofc 和 /或 Occ取零， 表达式可以简化。 需要说明的是， 本实施例新增的测量事件 中的分量载波包括服务小区对应的分量载波 CC ( fl ), 也可以不包括服务小 区对应的分量载波， 即仅适用于 CC ( f2 )、 CC ( β ) 和 CC ( f4 ), 基站 1在 测量配置中指明适用的分量载波信息。 基站 1也可以在测量配置中指明测量 标识应用的部分分量载波的信息， 比如仅指明 CC ( fl ) 和 CC ( f2 )、 或者 CC ( f2 ) 和 CC ( β ), UE在评估满足该测量标识对应的测量事件的进入条 件的测量对象时， 仅考虑指明的这部分分量载波。 在本实施例中， 测量标识 1对应的测量对象釆用明确的信令指示， 也可 以釆用默认的配置： 如默认该载波聚合小区的所有分量载波或除服务小区之 外的分量载波。 在载波聚合小区可能存在扩展载波（Extension carrier ), 这种 载波不能被 UE独立使用， 只能作为其他载波的资源载波， 当测量标识 1对 应的测量对象釆用默认的配置时， 也可以是该载波聚合小区除扩展载波之外 的所有分量载波、 或除服务小区和扩展载波之外的分量载波。 在本实施例中， 测量事件为分量载波的信号质量低于预定门限， 在实施 例一中， 测量事件为分量载波的信号质量高于预定门限， 可以将这两个测量 事件统一起来， 比如在测量事件为分量载波的信号质量高于预定门限时， 增 加一个标识 （测量配置中）， 当这个标识有效设置时 （如设置为 True), 如果 在小区列表中存在持续 TTT满足离开条件的分量载波， UE仍然需要触发测 量报告。 实施例三 在 LTE Advance系统中， 釆用如图 1所示的网络架构。基站 1所辖小区 1是载波聚合的小区， UE在小区 1中处于空闲状态。 这里， 基站 1即： 泛指 图 1中的任何一个 eNB。该载波聚合的小区包含的分量载波在频带 1,即 Band 1中， 下行有 4个连续的分量载波， 即： CC (fl)、 CC (f2)、 CC (fi)、 CC (f4); 上行也是 4个连续的载波， 即： CC (f5)、 CC (f6)、 CC ( f7 )、 CC ( f8 )。 四个下行载波均发送系统消息、 寻呼消息。 某个时刻， UE在分量载波（ UL CC ( f5 ), DL CC ( fl ) )发起随机接入， 成功接入该载波聚合的小区。 在本实施例中， UE 只有一个月艮务小区， 如果 UE需要接入更多的载波， UE视其他载波为资源载波。 此时 UE视当前的分 量载波 （ULCC (f4), DL CC ( fl ) ) 为服务小区。 为了实现移动性以及分量载波的管理， 基站 1向 UE发送测量配置， 在 测量配置中包含现有协议中的测量任务， 内容与实施例一所述类似。 为了实现本发明， 基站向 UE发送的测量配置还包括新的测量标识： 测量标识 1,该测量标识对应的测量对象为分量载波（ CC( f2 )、 CC( β )、 CC (f4), 可以用分量载波的标识表示如载波索引）、 或多个频点 （β、 β、 f4 )„ 该测量标识对应的测量事件 A6 (可以釆用其他的 A7或 A8标识）为非 激活分量载波的信号质量比服务小区的信号质量高预定的偏移量， 此处特指 该载波聚合小区的非激活分量载波的信号质量比服务小区的信号质量高预定 的偏移量。 测量标识 1还包括预定偏移量、 滞后参数 Hys、 TTT、 各分量载 波或各分量载波频率的偏移量等。 UE收到测量配置后， 对其中的测量标识进行参数初始化， 并获取测量 配置中的全部测量对象中的每个测量对象各自的属性和测量结果； UE 根据 初始化的参数或预定偏移量对每个测量对象的测量结果进行事件评估。 在本 实施例中， 由于有新的测量标识 1对应的测量对象为分量载波或多个频点， UE 初始化 CC ( f2 )、 CC ( β )、 CC ( f4 ) 对应的参数， 评估满足测量事件 A6进入条件的分量载波， 如果有经过层 3平滑处理 （ L3 filtering ) 的一个或 多个分量载波满足测量事件 A6的进入条件的持续时间大于或等于预定测量 触发时间长度 TTT, UE生成测量报告， 将满足条件的分量载波上报网络侧， 网络侧据此可以有效地管理分量载波。 在某个时刻， UE发现分量载波 CC ( f2 ) 和 CC ( β )在 ΤΤΤ时间内均 满足事件 Α6的进入条件， 即分量载波 CC ( f2 ) 和 CC ( β ) 的信号质量均 比服务小区的信号质量高预定的偏移量， CC ( f2 ) 和 CC ( β ) 的信号质量 的测量结果已经经过层 3的平滑处理 （ filtering ), UE将分量载波 CC ( f2 ) 和 CC ( β )放入测量标识 1对应的小区列表 cellsTriggeredList。 UE生成测 量标识 1的测量 4艮告， 该 4艮告包含分量载波 CC ( f2 )和 CC ( β )的标识（可 以是频率、 或者是分量载波的索引 Carrier Index, 或者是分量载波的物理层 标识 PCI或全局性标识 CGI )、 以及信号质量的测量结果 RSRP和 /或 RSRQ。 基站 1收到测量报告后， 获知分量载波 CC ( f2 ) 和 CC ( β ) 的信号质量， 才艮据 UE的业务需求、 分量载波的负荷状况分配 UE新的分量载波 CC ( f2 ), 基站 1通过 RRC信令发送新增分量载波的配置信息， UE收到后在两个下行 载波接收数据， 即此时 UE的下行激活载波数为 2, 在基站 1发送的新增分 量载波的配置中可以修改服务小区的设定， 如改成 CC ( f2 )与相应的上行载 波构成服务小区， 在本实施例中， 服务小区保持不变， 仍为 UE初始成功接 入的载波。 过了一段时间， UE发现分量载波 CC ( f4 ) 在 TTT时间内均满足事件
A6的进入条件， 即分量载波 CC ( f4 ) 的信号质量均比服务小区的信号质量 高预定的偏移量， CC ( f4 ) 的信号质量的测量结果已经经过层 3的平滑处理 ( filtering ), UE 将分量载波 CC ( f4 ) 放入测量标识 1 对应的小区列表 cellsTriggeredList。 UE生成测量标识 1的测量 4艮告，该报告包含分量载波 CC ( f4 )的标识（可以是频率、 或者是分量载波的索引 Carrier Index、 或者是分 量载波的物理层标识 PCI 或全局性标识 CGI )、 以及信号质量的测量结果 RSRP和 /或 RSRQ。 基站 1收到测量报告后， 获知分量载波 CC ( f4 ) 的信号 质量， 才艮据 UE的业务需求、 分量载波的负荷状况可以重新分配 UE激活的 分量载波或保持不变。 需要说明的是， 当 UE的激活载波由 CC ( fl ), 增加 到 CC ( fl )和 CC ( f2 )后， UE在评估满足事件 Α6触发条件的分量载波时 不需要再考虑 CC ( f2 ), 仅需考虑 CC ( β )和 CC ( f4 ), 网络可以通过修改 测量配置通知 UE需要评估的测量对象、 或者 UE 自动的 4爹改评估的测量对 象。 在本实施例中，釆用 A6标识的新的测量事件为非激活分量载波（下行） 的信号质量比服务小区的信号质量高预定的偏移量， 其进入条件或触发条件 用表达式表示为： Mc+Ofc+Occ-Hys>Ms+Ofs+Ocs+Off; 其离开条件用表达 式表示为： Mc+Ofc+Occ+Hys< Ms+Ofs+Ocs+Off, 在上述表达式中， Mc表 示非激活分量载波的测量结果 ( the measurement result of the non-active component carrier ), Ofc 表示非激活分量载波的频率特定的偏移量 （the frequency specific offset of the frequency of the non-active component carrier ), Occ 表示非激活分量载波的小区特定偏移量 （the cell specific offset of the non-active component carrier ), Hys表示滞后参数, Of 表示子员定偏移量, Ms 表示服务小区的测量结果， Ofs 表示服务小区的频率特定的偏移量， Ocs 表 示服务小区的小区特定偏移量。 此处如果 Ofc和 /或 Occ取零， 表达式可以简 化。 需要说明的是， 本实施例新增的测量事件也可以新增标识， 当标识有效 设置时， 在小区列表中存在持续 TTT满足事件离开条件的分量载波， UE也 需要触发测量报告。 实施例四 本实施例的场景与实施例一相同，只是新增的测量标识 1对应的测量对 象为载波聚合小区的全部或部分分量载波， 测量标识 1对应的测量事件为最 好的分量载波改变 （ Change of best component carrier )。 其进入条件的表达式 可以表示为（Mc + Ofc + Occ)non.best -Hys> (Mc + Ofc + Occ)best，其中的参数与其他实 施例相同。
UE收到测量配置后处理方式与其他的实施例相同， 基站 1收到 UE发 送的测量报告后对分量载波的管理与其他的实施例相同， 此处不再赞述。 实施例五 在 LTE Advance系统中， 釆用如图 1所示的网络架构。基站 1所辖小区 1是载波聚合的小区， UE在小区 1中处于空闲状态。 这里， 基站 1即： 泛指 图 1中的任何一个 eNB。该载波聚合的小区包含的分量载波在频带 1,即 Band 1中， 下行有 4个连续的分量载波， 即： CC (fl)、 CC (f2)、 CC (fi)、 CC
(f4); 上行也是 4个连续的载波， 即： CC (f5)、 CC (f6)、 CC ( f7 )、 CC
( f8 )。 四个下行载波均发送系统消息、 寻呼消息。 某个时刻， UE在分量载波（ UL CC ( f5 ), DL CC ( fl ) )发起随机接入， 成功接入该载波聚合的小区。 在本实施例中， UE 可以有多个月艮务小区， 如 果 UE 需要接入更多的分量载波， UE也视其他分量载波为月艮务小区。 此时 UE视当前的分量载波 （ULCC (f4), DL CC ( fl ) ) 为服务小区。 为了实现移动性以及分量载波的管理， 基站 1向 UE发送测量配置， 在 测量配置中包含现有协议中的测量任务， 内容与实施例一所述类似。 为了实现本发明， 基站向 UE发送的测量配置还包括新的测量标识： 测量标识 1,该测量标识对应的测量对象为分量载波（ CC( f2 )、 CC( β )、 CC (f4), 可以用分量载波的标识表示如载波索引）、 或多个频点 （β、 β、 f4 )„ 该测量标识对应的测量事件 A6 (可以釆用其他的 A7或 A8标识）为非 激活分量载波的信号质量比服务小区的信号质量高预定的偏移量， 此处特指 该载波聚合小区的非激活分量载波的信号质量比服务小区的信号质量高预定 的偏移量。 测量标识 1还包括预定偏移量、 滞后参数 Hys、 TTT、 各分量载 波或各分量载波频率的偏移量等。
UE收到测量配置后， 对其中的测量标识进行参数初始化， 并获取测量 配置中的全部测量对象中的每个测量对象各自的属性和测量结果； UE 根据 初始化的参数或预定偏移量对每个测量对象的测量结果进行事件评估。 在本 实施例中， 由于有新的测量标识 1对应的测量对象为分量载波或多个频点， UE 初始化 CC (f2)、 CC (β)、 CC ( f4 ) 对应的参数， 评估满足测量事件 A6进入条件的分量载波， 如果有经过层 3平滑处理 （ L3 filtering ) 的一个或 多个分量载波满足测量事件 A6的进入条件的持续时间大于或等于预定测量 触发时间长度 TTT, UE生成测量报告， 将满足条件的分量载波上报网络侧， 网络侧据此可以有效地管理分量载波。 在某个时刻， UE发现分量载波 CC ( f2 ) 和 CC ( β )在 ΤΤΤ时间内均 满足事件 Α6的进入条件， 即分量载波 CC ( f2 ) 和 CC ( β ) 的信号质量均 比服务小区的信号质量高预定的偏移量， CC (f2) 和 CC (β) 的信号质量 的测量结果已经经过层 3的平滑处理 （ filtering ), UE将分量载波 CC ( f2 ) 和 CC ( G )放入测量标识 1对应的小区列表 cellsTriggeredList。 UE生成测 量标识 1的测量报告， 该报告包含分量载波 CC ( f2 )和 CC ( β )的标识（可 以是频率、 或者是分量载波的索引 Carrier Index, 或者是分量载波的物理层 标识 PCI或全局性标识 CGI )、 以及信号质量的测量结果 RSRP和 /或 RSRQ。 基站 1收到测量报告后， 获知分量载波 CC ( f2 ) 和 CC ( β ) 的信号质量， 才艮据 UE的业务需求、 分量载波的负荷状况分配 UE新的分量载波 CC ( f2 ), 基站 1通过 RRC信令发送新增分量载波的配置信息， UE收到后在两个下行 载波接收数据， 即此时 UE的下行激活载波数为 2 , 此时 UE具有两个服务小 区。 基站 1可以向 UE发送新的测量配置表明测量标识 1对应的测量事件选 择比较的服务小区为 CC ( fl ) 或 CC ( f2 ), 同时修改测量对象的范围； 或 者基站不发送新的测量配置， UE 自己选择测量事件比较的服务小区， 在测 量报告中表明服务小区的信息即可， UE 同时修改测量对象的范围。 需要说 明的是， 基站 1在初始配置测量标识 1对应的测量对象可以只包含部分分量 载波。 在本实施例中，新增的测量事件是非激活载波的信号质量比服务小区的 信号质量高预定的偏移量， 新增的测量事件也可以是其他实施例所述的测量 事件。 在本实施例中， UE 可以有多个月艮务小区， 因此网络侧配置的测量事 件可以是仅应用于服务小区的， 新的测量事件可以是服务 'j、区之间的比较事 件， 如服务小区之间信号质量顺序改变的事件、 或最好的服务小区改变的事 件。 网络也可以配置应用于载波聚合小区部分或全部分量载波的周期性的测 量， UE在周期性的定时器超时时上报探测到的最好的一个或多个分量载波。 在上面的实施例中， 本发明的应用范围均限于 LTE 系统， 事实上在 UMTS系统， 本发明所述方法仍然适用， 在 UMTS中， 向 UE发送测量配置 的是无线网络控制器 RNC, UE在评估持续 TTT满足测量事件进入条件或触 发条件的测量对象时， UE 上报的测量报告包含的测量结果为 RSCP 和 /或 Ec/No。
从以上的描述中， 可以看出， 釆用本发明实施例提供的方法， 可以解决 了载波聚合小区 UE不能同时上报分量载波的测量结果的问题， 从而使网络 侧能够更好的管理分量载波以及为 UE调度合适的分量载波。 根据本发明的实施例， 提供了一种用户设备。 该用户设备能够用于实现根据本发明实施例的载波聚合中的测量方法。 图 3是根据本发明实施例的用户设备的示意图。 需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执 行指令的计算机系统中执行， 并且， 虽然在流程图中示出了逻辑顺序， 但是 在某些情况下， 可以以不同于此处的顺序执行所示出或描述的步骤。 如图 3所示， 该用户设备包括： 接收模块 301、 测量模块 303。 具体地， 接收模块 301用于接收测量配置， 其中， 测量配置中包括测量 事件， 其中， 测量事件为一个或多个分量载波的测量事件； 测量模块 303 , 连接至接收模块 301 , 用于根据接收模块 301接收的测量配置执行测量； 图 4是根据本发明优选实施例的用户设备的示意图。 优选地， 该用户设备还包括生成模块 304 , 连接至测量模块 303 , 用于 在测量模块 303 艮据测量配置执行测量之后生成测量艮告； 发送模块 305 , 连接至生成模块 304 , 用于向网络侧发送生成模块 304生成的测量报告。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布 在多个计算装置所组成的网络上， 可选地， 它们可以用计算装置可执行的程 序代码来实现， 从而， 可以将它们存储在存储装置中由计算装置来执行， 或 者将它们分别制作成各个集成电路模块， 或者将它们中的多个模块或步骤制 作成单个集成电路模块来实现。 这样， 本发明不限制于任何特定的硬件和软 件结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本 领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的 ^"神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护 范围之内。
