摘要:
Systems and methods of the present disclosure are directed to a method performed by a wireless communication device. The method includes receiving a configuration of a plurality of TCI states via RRC signaling. The method includes receiving a MAC CE that activates a subset of the plurality of TCI states. The method includes receiving a DCI that indicates one or more of the subset of the plurality of TCI states to be used and explicitly or implicitly indicates one or more particular CORESETs for which the one or more of the subset of the plurality of TCI states are to be used. The method includes using one or more spatial QCL downlink reference signals contained in the one or more of the subset of the plurality of TCI states to receive a PDCCH corresponding to the one or more particular CORESETs.
