1. A method performed by a user equipment (UE), the method comprising:
receiving a parameter related to discontinuous reception (DRX) operation through a higher layer;
receiving first downlink control information (DCI) comprising information related to physical downlink control channel (PDCCH) monitoring adaptation;
receiving second DCI for scheduling a physical downlink shared channel (PDSCH) within a DRX active time of the DRX operation, based on the PDCCH monitoring adaptation; and
receiving the PDSCH based on the second DCI,
wherein the UE determines a starting point of a time duration in which the PDCCH monitoring adaptation is performed, based on whether the first DCI is configured as a wake-up signal (WUS).
