Description

一种被用于多天线传输的用户设备、基站中的方法和装置 技术领域
本发明涉及无线通信系统中的传输方法和装置，尤其涉及被用于多天线传输的无线通信中传输方法和装置。
背景技术
现有的LTE(Long Term Evolution，长期演进)系统中，UE会在下行子帧中搜索DCI(Downlink Control Information，下行控制信息)以获取来自基站的调度(Grant)。考虑到DCI传输的鲁棒性(Robustness)以及高覆盖性需求，DCI对应的控制信道往往通过分集(Diversity)或者预编码循环(Precoder Cycling)的方式传输，而数据信道采用的多天线的传输方式及相关信息，往往由DCI，以及高层信令共同确定。
未来移动通信系统中，由于波束赋形(Beamforming)和大规模多天线系统的引入(Massive-MIMO)，下行控制及数据信道的传输方式将需要被重新设计。
发明内容
未来移动通信系统中，基站将会在多个发送波束(Tx-Beam)上的传输下行控制信道以及下行数据信道。与此同时，UE也将会在多个接收波束(Rx-Beam)上检测下行控制信道及下行数据信道。由于UE的移动性，旋转(Rotation)及传输路径阻碍(Blocking)的原因，UE可能在多个Tx-Beam或者多个Rx-Beam之间切换以获取较好的接收质量，特别是控制信令的接收质量。针对这个问题，一种解决方式就是UE在监测控制信令的同时监测用于接收控制信令的Beam的质量，当所述Beam质量变差时汇报给基站，并由基站重新给所述UE配置新的Beam。然而，此种方法存在一个显著的问题，即Beam的切换速度较慢，性能不能保证。
针对上述问题，本发明提供了解决方案。需要说明的是，在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。例如，本申请的UE中的实施例和实施例中的特征可以应用到基站中，反之亦然。
本发明公开了一种被用于多天线传输的UE中的方法，其中，包括如下步骤：

其中，所述第一无线信号包括第一信息，所述第二无线信号包括第二信息。目标信息被用于在所述第三时间段中的与多天线相关的接收。所述第二时间段的时域位置被用于确定所述目标信息是所述第一信息还是所述第二信息。所述第三时间段的时域位置被关联到所述第一时间段的时域位置。
作为一个实施例，上述方法的特质在于：所述第一信息被所述UE用于指示所述UE倾向的所述第三无线信号对应的{基站的Tx-Beam，终端的Rx-Beam}中的至少之一。当所述第三时间段和所述第一时间段满足给定要求，所述UE就按照所述第一信息对应的基站的Tx-Beam或者终端的Rx-Beam接收所述第三无线信号。

作为一个实施例，上述方法的好处在于：基站通过所述第二信息配置所述第三无线信号的接收方式，以保证当基站配置所述UE时，所述UE的接收依然基于基站的配置进行操作。上述方式保证终端依然基于基站的调度进行工作。
作为一个实施例，上述方法的再一个好处在于：通过将第一时间段和第三时间段的时域关系建立联系，上述基于UE的判断的波束赋形信息仅在所述第三时间段中生效，降低所述UE因错误选择波束而带来的风险概率。
