1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, a higher layer signaling including beam application time information and transmission configuration indication (TCI) state information;
receiving, from the base station, downlink control information (DCI) including a TCI state indication indicating a TCI state from the TCI state information;
identifying the TCI state based on the TCI state indication; and
transmitting, to the base station, an uplink (UL) signal based on the TCI state and the beam application time information, or
receiving, from the base station, a downlink (DL) signal based on the TCI state and the beam application time information,
wherein in case that a DCI format corresponding to the DCI is configured without DL assignments, one or more fields in the DCI format are set to pre-defined value.
