Claim 0:
1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, downlink control information (DCI) including first information related to at least one transmission configuration indication (TCI) state, second information related to time domain resource assignment, and third information related to a physical uplink control channel (PUCCH) resource indication, the DCI being with or without scheduling a physical downlink shared channel (PDSCH);
transmitting, to the base station, hybrid automatic repeat request-acknowledgement (HARQ-ACK) information, based on the DCI without scheduling the PDSCH; and
applying the at least one TCI state based on the first information, after transmitting the HARQ-ACK information,
wherein the HARQ-ACK information corresponds to a detection of the DCI providing an update of the at least one TCI state without scheduling the PDSCH, and
wherein the DCI without scheduling the PDSCH is based on a specific value of at least one of frequency domain resource assignment (FDRA) field, redundancy version (RV) field, modulation and coding scheme (MCS) field, or new data indicator (NDI) field of the DCI.
