图 1为应用 CoMP技术的典型场景示意图, 如图 1所示, 初始接入时, UE接入一个 CRS最强的小区, 同时该 UE不断向宏基站(eNB)上报多个微 基站 (TP) 的参考信号接收功率 (Reference Signal Receiving Power; 简称: RSRP),判断该 UE是否处于小区边缘。如果该 UE处于小区边缘,则该 eNB 的基站控制单元决策使用的传输模式可以为动态点选择 (dynamic point selection; 简称: DPS ) /动态点关闭 (dynamic point blanking; 简称: DPB ) 等。 另外, eNB还可以为每个 UE配置一套或多套物理下行共享信道的资源 单元映射和准共址指示 (PDSCH RE Mapping and Quasi-co-located indication; 简称: PQI) 信息, 其中, 每套 PQI信息中包括 UE时频估计使用的 CRS或 者 CSI-RS; CRS用于频率跟踪; CSI-RS用于定时跟踪; 同时 eNB通过 DCI 信令通知该 UE目前使用那套 PQI信息, 其具体实现方式为: UE获取一套或 多套 PQI信息, 再根据获取的 DCI信令, 确定使用哪套 PQI信息, 从而根据 确定的 PQI信息中获取的 CRS或者 CSI-RS, 跟踪导频估计出对应的定时偏 差和频率偏差, 并对接收的数据进行时频校正。
但是, 如果上述 CRS是由宏基站发送给 UE, 而数据是由微基站发送给 UE, 当宏基站和微基站的频率不同步时, 如果 UE使用宏基站发送的 CRS来 估计频偏, 来纠正微基站发送的数据, 将导致性能下降。 或者, 如果微基站 和宏基站都发送 CRS的话, 那么 UE估计的频偏也是两个基站的合成频偏, 如果用于对微基站发送的数据进行解调, 也会导致性能下降。 发明内容

步骤 101、 接收第一基站发送的通知消息; 该通知消息包括指示标识, 该指示标识用于指示接收到的该第一基站发送的 RRC信令中的 CRS是否有 效。
可选地, 该通知消息可以为 RRC信令或者 DCI信令。
在本实施例中, 举例来说, 当通知消息为 RRC信令时, 可以通过在 RRC 信令中增加一个字段以用于表示 CRS是否有效。 具体的, 在 RRC信令中增 加一个字段以用于表示 CRS 是否有效的方式为: 在 RRC 信令中的 "CSI-RS-ConfigNZP"字段信息中增加一个 "value_qcl-CRS-Info-rll"字段, 例 如: 当" value_qcl-CRS-Info-rir这个字段为 1, 则表明 CRS 有效; 当 "value_qcl-CRS-Info-rir,这个字段为 0, 则表明 CRS无效。 具体的,本发明实施例中提供的在 RRC信令中增加一个字段以用于表; CRS有效的方法的实现方式示例如下:
CSI-RS-ConfigNZP-rl 1: := SEQUENCE {
csi-RS-IdentityNZP-rl 1 CSI-RS-IdentityNZP-rll,
antennaPortsCount-r 11 ENUMERATED {anl, an2, an4, an8}, resourceConfig-rl 1 INTEGER (0..31),

OPTIONAL, Need OR
或者, 当通知消息为 RRC信令时, 可以通过在 RRC信令中修改一个字 段以用于表示 CRS是否有效。 具体的, 在 RRC信令中修改一个字段以用于 表示 CRS是否有效的方式为: 当 RRC信令中的" CSI-RS-ConfigNZP"字段信 息中的 "qcl-CRS-Info-rll"这个字段修改为' OPTIONAL— Need OR"这个字段 时, 表明 CRS 有效; 当 RRC 信令中的" CSI-RS-ConfigNZP"字段信息中的 "qcl-CRS-Info-rl l"这个字段没有修改为 "OPTIONAL— Need OR"这个字段时, 表明 CRS无效。
具体的,本发明实施例中提供的在 RRC信令中修改一个字段以用于表示 CRS有效的方法的实现方式示例如下:
CSI-RS-ConfigNZP-rl l:: = SEQUENCE {

或者, 当通知消息为 DCI信令时, 可以通过 C-RNTI加扰 DCI信令中的 一个 bit来指示当前 CRS是否有效, 或者复用现有协议中的 DCI信令中的一 个 bit来指示当前 CRS是否有效。
需要说明的是,当通知消息为 DCI信令时,还可以通过 C-RNTI加扰 DCI 信令中的两个 bit来指示当前 CRS是否有效, 或者复用现有协议中的 DCI信 令中的两个 bit来指示当前 CRS是否有效。换言之, 对于用几个 bit来指示当 前 CRS是否有效, 本发明实施例并不对此进行限制。
步骤 102、若确定该指示标识用于指示该 RRC信令中的 CRS无效,则根 据第二基站发送的 CSI-RS或者 DMRS,对接收到的该第二基站发送的数据进 行时频跟踪处理。
在本实施例中, 接收第一基站发送的通知消息, 若确定该通知消息中的 指示标识用于指示接收到的第一基站发送的 RRC信令中的 CRS无效, 则根 据第二基站发送的 CSI-RS或者 DMRS,对接收到的该第二基站发送的数据进 行时频跟踪处理, 由于数据和用于时频跟踪导频都是从同一基站发出的, 因 此估计的频偏和数据的频谱是一样的, 从而解决了现有技术中 CRS是由宏基 站发送给 UE, 而数据是由微基站发送给 UE, 当宏基站和微基站的频率不同 步时, 如果 UE使用宏基站发送的 CRS来估计频偏, 来纠正微基站发送的数 据, 将导致性能下降。 或者, 如果微基站和宏基站都发送 CRS 的话, 那么 UE估计的频偏也是两个基站的合成频偏,如果用于对微基站发送的数据进行 解调, 也会导致性能下降的问题。
图 2为本发明数据的处理方法的另一个实施例的流程示意图,在本实施例 中, 以通知消息为 RRC信令为例,详细介绍本实施例的技术方案,如图 2所示, 本实施例的执行主体为 UE, 则该方法包括:

举例来说, 如果是 Behavior A或 B场景, 则将" CSI-RS-ConfigNZP-rll" 字 段 修 改 成 "CSI-RS-ConfigNZP-behaviorAB-rll" 字 段 , 该 "CSI-RS-ConfigNZP-behaviorAB-rl Γ字段用于指示 CRS和 CRS-RS可以做相 应时频估计; 如果是 Behavior C场景, 则将" CSI-RS-ConfigNZP-rll"字段修 改 成 "CSI-RS-ConfigNZP-behaviorC-rl l" 字 段 , 该 "CSI-RS-ConfigNZP-behaviorC-rll"字段用于指示使用该新增加 RRC信令中 的 CSI-RS或者 DMRS做相应时频估计和信道估计。
