Abstract: 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.

Abstract: A method and a device for monitoring a downlink control channel of a terminal are provided. The method comprises: receiving a first setting message that indicates the direction of resources of a slot and a second setting message that indicates a monitoring occasion for detecting a wake up signal (WUS); and monitoring a second downlink control channel in the next DRX-on section, if a resource constituting the monitoring occasion overlaps a resource designated as an uplink by the first setting message so that first downlink control channel monitoring for detecting the wake up signal is not required.

Abstract: Provided are a method of performing a channel access procedure by an apparatus in an unlicensed band, and an apparatus using same method. The apparatus determines a contention window size (CWS) and performs a channel access procedure with respect to a first channel on the basis of the determined contention window size. The contention window size may be adjusted on the basis of feedback information relating to a second channel. When a transmission history of the second channel, which is to be reflected in determining the contention window size, does not exist, the contention window size may be determined to be a minimum CWS value in a specific channel access priority class.
