1. A method for a user equipment (UE) monitoring a physical downlink control channel (PDCCH), the method comprising:
receiving a first configuration from a base station to configure the UE with a first search space of the PDCCH, wherein the first search space is used for monitoring a scheduling signal used for indicating scheduling information;
receiving a second configuration from the base station to configure the UE with a second search space of the PDCCH, wherein the second search space is used for monitoring a power saving signal used for indicating wake-up information associated with a Discontinuous Reception (DRX) functionality;
monitoring the first search space according to the first configuration in response to the UE being in a DRX active time of the DRX functionality, wherein the DRX active time is a time during which the UE monitors the PDCCH for the scheduling information;
monitoring the second search space according to the second configuration in response to the UE being in a DRX inactive time of the DRX functionality;
not monitoring the second search space in response to the UE being in the DRX active time of the DRX functionality; and
in response to not receiving the power saving signal while monitoring the second search space, starting a DRX on-duration timer of the DRX functionality.
