1. A method of monitoring a physical downlink control channel (PDCCH) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving configuration message informing of a monitoring occasion for detecting a wake up signal (WUS); and
based on that a first PDCCH monitoring for detecting the WUS is not required in the monitoring occasion, performing a second PDCCH monitoring in a next discontinuous reception (DRX)-on duration,
wherein the WUS is first downlink control information (DCI) including a wake-up indication,
wherein the second PDCCH monitoring is for detecting a second DCI other than the first DCI, and
wherein based on a resource constituting the monitoring occasion overlapping with a long term evolution (LTE) cell specific reference signal (CRS) resource indicated by a network, the first PDCCH monitoring is not required in the monitoring occasion.
