Description

准共址假设的确定方法及装置、存储介质和电子装置 技术领域
本公开涉及通信领域，具体而言，涉及一种准共址假设的确定方法及装置、存储介质和电子装置。
背景技术
一种波束指示方法，特别是物理下行参考信号或信道的接收波束指示，如PDCCH(Physical Downlink Control Channel，物理下行控制信道)、PDSCH(Physical Downlink Shared Channel，物理下行共享信道)、CSI-RS(Channel State Information Reference Signals信道状态信息参考信号)，其具体做法是首先通过一个MAC(Medium Access Control，媒体接入控制)-CE(Control Element，控制单元)信令来激活一个TCI(Transmission Configuration Indication，传输配置指示)状态或选择一个TCI状态集合，其次，根据TCI状态来确定目标下行参考信号或信道的准共址(Quasi-Colocation,QCL)假设，具体地，根据TCI状态关联的QCL-Type D中配置的源参考信号来确定目标下行参考信号或信道的接收波束。整个过程局限于单个服务小区或载波单元(Component Carrier，CC)或部分带宽(Bandwidth Part，BWP)。
然而，在CA(Carrier Aggregation，载波聚合)场景中，用户设备(User Equipment,UE)在下行连接中可能会支持最多16个CC或BWP，此时，对于所有CC或BWP上的PDCCH、PDSCH、CSI-RS的波束指示，需要在每个CC或BWP上通过一个MAC-CE信令来激活一个TCI状态(或选择一个TCI状态集合)来完成，这样就会需要最多16个MAC-CE信令。例如，16个CC或BWP上的PDCCH被16个MAC-CE信令激活的16个TCI状态指示了相同的波束，导致信令开销大。针对相关技术中的上述问题，目前尚未存在有效的解决方案。

    所述第一TCI状态是所述TCI状态集合中的第一个TCI状态；
    所述第一通信节点通过激活命令从所述TCI状态集合中激活所述第一TCI状态。
  15. 根据权利要求13所述的方法，其中，所述参考CC或BWP包括以下至少之一：
    所述CC组或BWP组中具有最小CC或BWP索引的CC或BWP；
    所述CC组或BWP组中与所述第二类CC或BWP索引之间间隔最小的CC组或BWP；
    所述CC组或BWP组中距离所述第二类CC或BWP频域位置最近的CC或BWP。
  16. 一种准共址假设的确定装置，包括：
    确定模块，设置为根据第一通信节点为接收第二类载波单元CC 或部分带宽BWP的目标下行参考信号或信道指示的传输配置指示TCI状态来确定第二类CC或BWP的目标下行参考信号或信道的QCL假设；
    其中，所述TCI状态关联以下至少之一配置信息：第一源参考信号、第二源参考信号、第一源参考信号的偏移量集合、第一源参考信号的偏移量对应的CC或BWP索引集合；
    其中，所述第一源参考信号指在第一类CC或BWP上传输的提供第一QCL类型的源参考信号；所述第二源参考信号指被在第一类CC或BWP上传输的第二QCL类型的源参考信号；其中，所述第一类CC或BWP和第二类CC或BWP被配置于相同的CC组或BWP组。
  17. 一种存储介质，所述存储介质中存储有计算机程序，其中，所述计算机程序被设置为运行时执行所述权利要求1至15任一项中所述的方法。
  18. 一种电子装置，包括存储器和处理器，所述存储器中存储有计算机程序，所述处理器被设置为运行所述计算机程序以执行所述权利要求1至15任一项中所述的方法。
