1. A method for performing physical downlink control channel (PDCCH) monitoring in a wireless communication system, the method performed by a user equipment (UE) and comprising:
receiving a power saving signal configuration from a network;
monitoring the power saving signal at more than one monitoring occasion before a next on-duration based on the power saving signal configuration,
wherein the power saving signal is downlink control information (DCI) on a physical downlink control channel (PDCCH), and
wherein the DCI is related to a power saving radio network temporary identity (PS-RNTI); and
based on the power saving signal being detected, performing the PDCCH monitoring at the next on-duration,
wherein the power saving signal includes configuration information related to the PDCCH monitoring,
wherein the configuration information includes a search space set configuration including a monitoring period related to a search space set in which the PDCCH monitoring is performed, a monitoring pattern related to the PDCCH monitoring, a duration, an aggregation level (AL), monitored DCI and a number of candidates, and
wherein the PDCCH monitoring is performed in the search space set based on the search space set configuration.
