Abstract: The present disclosure relates to a method of monitoring, by a wireless device, a downlink channel or a downlink signal. The method may include a step of receiving configuration information on a power save signal. The power saving signal can be used to signal that the downlink channel or the downlink signal should be monitored later. The configuration information may contain configuration information on an opportunity to omit the power saving signal. The method may include a step of monitoring the downlink channel or the downlink signal without monitoring the energy saving signal during the opportunity to omit. The length and/or position of the opportunity of omission can be determined according to the configuration information of a discontinuous receive cycle (DRX).

Abstract: Provided are a method for accessing a channel in an unlicensed band and a device using same method. The method is configured such that a wireless device transmits data units, receives feedback information about the data units, and adjusts a contention window size used in a determination of whether there is an access to the channel in the unlicensed band on the basis of the feedback information. The wireless device can adjust the contention window size by using feedback information about, from among the data units, data units which at least partially overlap in reference duration.
