A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH). The UE reports, to a base station, a reduced PDCCH monitoring capability for at least one group of search space sets (SSS) of a PDCCH, receives, from the base station, a reduced monitoring capability (MO) configuration, wherein the base station determines the reduced MO configuration based on the reported reduced PDCCH monitoring capability and monitors the PDCCH based on the reduced MO configuration.
