Description

被用于无线通信的用户设备、基站中的方法和装置 技术领域
本申请涉及无线通信系统中的方法和装置，尤其是涉及支持多天线的无线通信系统中的方法和装置。
背景技术
大尺度(Massive)MIMO成为下一代移动通信的一个研究热点。大尺度MIMO中，多个天线通过波束赋型，形成较窄的波束指向一个特定方向来提高通信质量。多天线波束赋型形成的波束一般比较窄，通信双方的波束需要对准才能进行有效的通信。为了保证UE(User Equipment，用户设备)能用正确的波束来接收或者发送数据，基站在调度信令中发送波束指示信息。由于UE侧监测和解码调度信令需要一定时间，当UE需要使用调度信令中指定的波束来接收下行数据时，基站需要在调度信令和下行数据之间预留足够的时间间隔。
根据3GPP(3rd Generation Partner Project，第三代合作伙伴项目)TS(Technical Specification，技术规范)38.214，当跨载波调度信令和下行数据之间的时间间隔小于一个阈值，或者跨载波调度信令中不包括下行数据的波束指示信息时，UE用一个默认的PDSCH(Physical Downlink Shared CHannel，物理下行共享信道)上关联的QCL参数来接收下行数据；当自调度信令和下行数据之间的时间间隔小于一个阈值，或者自调度信令中不包括下行数据的波束指示信息时，UE用一个默认的CoReset(Control Resource Set，控制资源集合)的QCL参数来接收下行数据。
发明内容
发明人通过研究发现，当一个载波能被2个载波调度时，如何确定下行数据的QCL(Quasi CoLocated，半共址)参数是一个需要解决的问题。尤其考虑到被调度载波是主载波时，被调度载波上能够被配置控制资源集合，现有确定PDSCH的QCL参数的方法可能需要被进一步增强。
针对上述问题，本申请公开了一种解决方案。需要说明的是，在本申请的描述中，只是采用主载波为被调度载波作为一个典型应用场景；本申请也同样适用于面临相似问题的其他场景，例如被调度载波是辅载波，并取得类似被调度载波是主载波场景中的技术效果。此外，不同场景采用统一解决方案还有助于降低硬件复杂度和成本。在不冲突的情况下，本申请的任一节点中的实施例和实施例中的特征可以应用到任一其他节点中。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。
