在具体实现过程中，上述测量配置信息可以是如表 3-1和 3-2所示的按 小区类型或功率区分的测量配置表； 也可以是如表 4所示的测量配置表。 表 3-1、 3-2和表 4中的 RSRP及其对应的测量周期仅为示例性数值， 在具 体实现过程中可以根据网络实际情况进行设定。

402, UE接收 eNB发送的聚合载波小区的类型信息或功率信息。 在具 体实现过程中， eNB可以通过广播消息或无线资源控制消息向 UE发送聚 合载波小区的类型信息或功率信息。
403， UE才艮据上述接收到的聚合载波小区的类型信息或功率信息， 以 及上述聚合载波小区中非激活单元载波 CC1和 CC2的 RSRP和上述测量配 置信息 （如表 3-1和 3-2， 或者表 4 )选择 CC1和 CC2的测量周期。
例如， 如果 UE收到 eNB发送的聚合载波小区的类型信息为 Pico, 并 且在 T1时刻 CC1和 CC2的 RSRP都小于 -84dBm， 则 UE根据表 3-2或表 4选择 CC1和 CC2的测量周期为 10s;当 UE移动到 T2时刻的位置时， CC1 和 CC2的 RSRP在 -84dBm和 -44dBm之间， 则 UE根据表 3-2或表 4选择 CC1和 CC2的测量周期为 ls。 或者， 如果 UE收到 eNB发送的聚合载波小 区的功率为 40W， 在 T1时刻， CC1的 RSRP小于 -lOOdBm, CC2的 RSRP 在 -lOOdBm和 -60dBm之间， 则 UE根据表 3-1或表 4选择 CC1的测量周期 为 10s， 选择 CC2的测量周期为 Is; 当 UE移动到 T2时刻位置时， CC1的 RSRP在 -lOOdBm和 -60dBm之间， CC2的 RSRP大于 -60dBm， 则 UE根据 表 3-1或表 4选择 CC1的测量周期为 ls， 选择 CC2的测量周期为 100ms。
404， UE根据上述选择的测量周期对 CC 1和 CC2进行测量。 本实施例提供的聚合载波小区测量的方法， 能够实现在聚合载波小区 中， UE对不同的单元载波进行不同周期的测量， 避免过度测量导致的电量 耗费， 同时能够及时根据 RSRP激活非激活单元载波。

在具体实现过程中， 上述测量配置信息可以是如表 5-1、 5-2和 5-3所 示的根据 UE速度信息区分的测量配置表；也可以是如表 6所示的测量配置 表。 表 5-1、 5-2、 5-3和表 6中的 RSRP及其对应的测量周期仅为示例性数 值， 在具体实现过程中可以根据网络实际情况进行设定。

502, UE根据自身当前的速度（例如网络计算获得的 UE 当前速度值 或 UE自身获得的当前速度值）和上述聚合载波小区中非激活单元载波 CC1 和 CC2的 RSRP， 以及上述测量配置信息（例如 5-1、 5-2和 5-3， 或者表 6 ) 选择 CC1和 CC2测量周期。
例如， 在 T1时刻， 如果 UE为低速运动， 速度小于 5km/h， 并且 CC1 和 CC2的 RSRP都小于 -84dBm， 则 UE根据上述表 5-1或表 6选择 CC1和 CC2的测量周期为 20s; 当 UE移动到 T2时刻的位置时， 如果 UE为中速 运动，速度大于 5km/h小于 30km/h， 并且 CC1和 CC2的 RSRP在 -lOOdBm 和 -70dBm之间， 则 UE根据表 5-2或表 6选择 CC1和 CC2的测量周期为 2s。或者，在 T1时刻，如果 UE为低速运动，速度小于 5km/h， CC1的 RSRP 小于 -84dBm， CC2的 RSRP在 -84dBm和 -44dBm之间， 则 UE根据表 5-1 或表 6选择 CC1的测量周期为 20s， 选择 CC2的测量周期为 5s; 当 UE移 动到 T2时刻的位置时， 如果 UE为高速运动， 速度大于 30km/h， CC1 的 RSRP在 -l lOdBm和 -70dBm之间， CC2的 RSRP大于 -70dBm， 则 UE根据 表 5-3或表 6选择 CC1的测量周期为 ls， 选择 CC2的测量周期为 100ms。
503 , UE根据上述选择的测量周期对 CC1和 CC2进行测量。
本实施例提供的聚合载波小区测量的方法， 能够实现在聚合载波小区 中， UE对不同的单元载波进行不同周期的测量， 避免过度测量导致的电量 耗费， 同时能够及时根据 RSRP激活非激活单元载波。
与上述图 2-图 5所示的方法实施例不同， 以下方法实施例中， 测量配置 信息中包含的 RSRP信息及其对应的测量周期为 RSRP值及其对应的测量周 期。
如图 6所示， 本实施例提供的聚合载波小区测量方法， 包括以下内容。 601 , UE接收 eNB发送的测量配置信息， 或 UE从预设信息中获取测 量配置信息， 该测量配置信息中包含 RSRP值及其对应的测量周期。
在具体实现过程中， eNB 可以通过广播消息或无线资源控制消息发送 上述测量配置信息； 或者上述测量配置信息可以是该 UE生产厂商预设的， 例如预设到该 UE的外部存储设备（如用户卡）中， 或者预设到该 UE存储 的信息中， UE可以从用户卡或者该 UE存储的预设信息中获取上述测量配 置信息。 可选地， 当运营商需要更新或优化该测量配置表时， 可以通过 UE 软件进行升级。
上述该测量配置信息可以是如表 7所示的测量配置表。表 7中的 RSRP 值及其对应的测量周期仅为示例性数值， 在具体实现过程中可以根据网络 实际情况进行设定。 表 7
Figure imgf000017_0001
可选地，上述表 7中还可包含测量周期上限值（例如 20s )及对应的 RSRP 最小门限值， 以及测量周期下限值 (例如 10ms )及对应的 RSRP最大门限值， 当 CC1或 CC2的 RSRP小于 RSRP最小门限值， 都采用测量周期上限值进行测 量， 当 CC1或 CC2的 RSRP大于 RSRP最大门限值， 都采用测量周期下限值进 行测量。
602, UE接收 eNB发送的测量周期计算信息。
603 , UE根据聚合载波小区中非激活单元载波 CC1和 CC2的 RSRP、上述 测量周期计算信息、 以及上述测量配置信息 （如表 7 )计算 CC1和 CC2的测 量周期。
例如， 当上述测量周期计算信息为线性差计算规则， 根据上述表 7和图 6-a所示线性关系示意图， A点 RSRP为 Xa= -70dBm， 对应的测量周期为 Ya=10s; B点 RSRP为 Xb= -44dBm， 对应的测量周期为 Yb=100ms; CCl的 RSRP为 Xcc 1， CC2的 RSRP为 Xcc2。根据线性关系可计算 CC 1的测量周期为：
Yccl= Yb-(Yb-Ya)*( Xccl-Xa)/(Xb-Xa);
CC2的测量周期为：
Ycc2= Yb-(Yb-Ya) · ( Xcc2-Xa)/(Xb-Xa)。
再例如， 当上述 eNB发给 UE的测量周期计算信息为： 如图 6-b所示的非 线性（如抛物线）计算规则和测量周期计算参数 γ (如 -0.1 )， 根据上述表 7 和图 6-b， A点 RSRP为 Xa= -70dBm，对应的测量周期为 Ya=10s; CCl的 RSRP 为 Xccl， CC2的 RSRP为 Xcc2。 可分别根据如下公式计算 CCl和 CC2的测量 周期 Yccl和 Ycc2:
(Xccl-Xa)=y · (Yccl-Ya)2; (Xcc2-Xa)=y · (Ycc2-Ya)2。
除上述两种举例的测量周期计算信息和相应计算方法， 本领域技术人 员还可以使用例如立方差等其他计算方法计算获得 CC1 和 CC2 的测量周 期。 另外， 本实施例还可以根据多个 RSRP值划分为多个区间， 在每个区 间内分别根据测量周期计算信息进行计算。

可选地， 上述表 8-1、 8-2、 9、 10-1、 10-2、 10-3和表 11中还可包含测 量周期上限值 (例如 20s )及对应的 RSRP最小门限值， 以及测量周期下限 值（例如 10ms )及对应的 RSRP最大门限值， 当 CC1或 CC2的 RSRP小 于 RSRP最小门限值， 都采用测量周期上限值进行测量， 当 CC1或 CC2的 RSRP大于 RSRP最大门限值， 都采用测量周期下限值进行测量。
702, UE接收服务基站发送的该聚合载波小区的类型信息或功率信息， 或根据 UE当前的速度 (例如网络计算获得的 UE当前速度值或 UE自身获得 的当前速度值）， 选择相应的 RSRP值及其对应的测量周期。
例如，如果 UE接收到 eNB发送的聚合载波小区的类型信息为 Macro小区 或功率信息为 40W， 则 UE选择表 8-1的 RSRP值及其对应的测量周期， 或选 择表 9中对应 Macro小区或功率信息为 40 W的 RSRP值及其对应的测量周期。 如果 UE当前速度为 20km/h， 则 UE选择表 10-2的 RSRP值及其对应的测量周 期， 或选择表 11中对应 （5km/h， 30km/h )的 RSRP值及其对应的测量周期。
703 , UE接收 eNB发送的测量周期计算信息。 703和 702的执行顺序可以 互换。
704, UE根据聚合载波小区中非激活单元载波 CC1和 CC2的 RSRP、 上述选择的 RSRP值及其对应的测量周期、 以及上述测量周期计算信息， 计算获得非激活单元载波 CC1和 CC2的测量周期。具体的计算方法可参考 上述实施例中 603的具体内容， 此处不再赘述。
705 , UE根据上述计算获得的测量周期对 CC1和 CC2进行测量。
本实施例提供的聚合载波小区测量的方法， 能够实现在聚合载波小区 中， UE对不同的单元载波进行不同周期的测量， 避免过度测量导致的电量 耗费， 同时能够及时根据 RSRP激活非激活单元载波。
在上述实施例中，非激活单元载波 CC1和 CC2的 RSRP的获取方法可 以包括： 测量聚合载波小区中的非激活单元载波 CC1和 CC2， 获取 CC1和 CC2的 RSRP; 或者，根据已有激活单元载波或非激活单元载波的 RSRP计 算上述非激活单元载波的 RSRP。 例如： 根据激活单元载波 CC1的 RSRP， 计算非激活单元载波 CC1和 CC2的 RSRP; 或者已知非激活单元载波 CC1 的 RSRP， 根据 CC1的 RSRP计算 CC2的 RSRP。 例如： 在 T1时刻所在地 理位置上 UE根据 CC3 的 RSRP计算得到 CC2 和 CC1 的 RSRP都小于 -lOOdBm,根据前述表 1的内容，则 UE选择 CC1和 CC2的测量周期为 10s; 而在 T2时刻所在地理位置上 UE根据 CC3的 RSRP计算出 CC2的 RSRP 是 -60dBm到 -100dBm， CC1的 RSRP小于 -100dBm， 根据前述表 1的内容， 则 UE选择 CC2的测量周期为 ls， CC1的测量周期为 10s。
具体根据已知 CC的 RSRP计算聚合载波小区中其他 CC的 RSRP的原理 如下： CC1， CC2和 CC3的发射功率不同， 且 RSRP都是以同心圓的方式向 外衰减， 导致 CC1， CC2和 CC3达到 UE的 RSRP不同， 但 CC之间存在差值， 因此可以根据已知 CC的 RSRP和该差值计算获得其他 CC的 RSRP。 具体地， 在各个单元载波同频带的情况下， 在统计学上各个单元载波的 RSRP差值是 固定的， 因此可以通过已知单元载波的 RSRP和固定差值计算获得其他单元 载波的 RSRP。 在各个单元载波异频带的情况下， 虽然在统计学上各个单元 载波的 RSRP差值是不固定的，但也可以计算获得，例如： UE实测上报 RSRP， 然后网络将该实际差值发送给 UE， UE就能够根据已知的 CC的 RSRP和该实 际差值计算其他 CC的 RSRP; 或者也可以在系统配置的时候， 配置固定的 CC之间的差值， 例如根据实测数据在系统配置时设置聚合载波小区中不同 CC之间的差值， 那么 UE就能够根据已知 CC的 RSRP和该系统配置的差值计 算其他 CC的 RSRP。在利用已知单元载波的计算非激活载波 RSRP的方式下， 配置信息中可以配置： 当非激活载波 RSRP值小于某个门限值时， 该非激活 载波的测量周期为 +∞， 即不测量。
上述图 2-图 7对应的方法实施例仅以测量配置信息中的信号估计值信 息为 RSRP信息为例进行介绍， 当测量配置信息中的信号估计值信息为信 号质量信息（如 RSRQ )或信号路损信息时的实现方式，与上述实施例类似， 例如可以将上述表 1-表 11中的信号功率替换为信号质量（例如 RSRQ )或 信号路损， 并相应替换其中的数值和测量周期， 此处不再赘述。
