Description

空间关系信息的确定方法及装置 技术领域
本申请涉及通信领域,具体涉及空间关系信息的确定方法及装置。
背景技术
现有的波束管理中,下行或上行信道或信号的波束选择具有很大的灵活性,且每个物理信道或信号(如物理下行控制信道(PDCCH,Physical Downlink Control Channel)、物理层下行共享信道(PDSCH,Physical Downlink Shared Channel)、探测参考信号(SRS,Sounding Reference Signal)、物理上行链路控制信道(PUCCH,Physical Uplink Control Channel))的波束指示是独立配置的。例如,对于PDCCH的波束指示,基站通过一个激活命令,如媒体访问控制层控制单元(MAC-CE,Media Access Control-Control Element)信令为其指示(或激活)一个传输控制指示(TCI,Transmission control indicator)状态,该TCI状态包括一个D类准共定位(QCL-Type D,Quasi Co-Located Type D)下行参考信号;对于PUCCH,基站通过一个MAC-CE信令为其指示一个空间关系信息,该空间关系信息包括一个上行或下行参考信号。然而,这种波束指示方法可能会导致过大的信令(如MAC-CE信令)开销。在上、下行信道互益性的情况下,基站可能会为TCI状态(QCL-Type D)和空间关系信息配置相同的下行参考信号,例如,基站通过一个MAC-CE信令为PDCCH激活了一个TCI状态,该TCI状态包括一个QCL-Type D下行参考信号,而基站又通过一个MAC-CE信令为PUCCH指示了一个具有相同下行参考信号的空间关系信息,这显然是多余的。对于这种因冗余指示空间关系信息所导致的信令开销过大的问题,目前尚且没有有效的解决方法。
