Claim of US Patent No. 11,071,101


1. A method for determining a transmission configuration indicator (TCI) of a user equipment (UE) in a wireless communication system, the method comprising:receiving a radio resource control (RRC) signal including a plurality of TCI states;
receiving a medium access control (MAC) control element (CE) informing one TCI state among the plurality of TCI states; and
determining a TCI for a control resource set (CORESET) based on the RRC signal and the MAC CE,
wherein the RRC signal is a first RRC signal including TCI states related to a physical downlink shared channel (PDSCH) or a second RRC signal including TCI states related to a physical downlink control channel (PDCCH), and
wherein based on the CORESET being a specific CORESET, the MAC CE informs one TCI state among the TCI states related to the PDSCH, and based on the CORESET not being the specific CORESET, the MAC CE informs one TCI state among the TCI states related to the PDCCH.
