Provided are a method and device for monitoring a downlink control channel of a terminal in a wireless communication system. The terminal receives configuration information which informs of the position of an SSB or configuration information which informs of the position of an LTE CRS, and receives configuration information which informs of a monitoring occasion for detecting a wake up signal (WUS). If first PDCCH monitoring for detecting the wake up signal is not required since a resource of the monitoring occasion overlaps with a resource of the SSB and/or a resource of the LTE CRS, the terminal performs second PDCCH monitoring in a next discontinuous reception (DRX)-on duration.
