1. A method for a base station (BS) instructing a user equipment (UE) to monitor a physical downlink control channel (PDCCH) for power saving signaling, the method comprising:
receiving from the UE, a UE capability information comprising a required time for the UE to wake up after receiving power saving signaling;
transmitting a discontinuous reception (DRX) configuration to the UE for configuring the UE to monitor a scheduling signal on the PDCCH within a DRX active time;
determining a power saving signaling configuration according to the required time, the power saving signaling configuration comprising a time offset prior to a start of a DRX on-duration time, and for instructing the UE to start monitoring the PDCCH for the power saving signaling; and
transmitting the power saving signaling configuration to the UE for configuring the UE to monitor the power saving signaling on the PDCCH, and for instructing the UE to wake up for monitoring the scheduling signal in the DRX active time.
