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.

Abstract: The present disclosure provides a method for receiving a synchronization signal/physical broadcast channel (SS/PBCH) block by a terminal in an unlicensed band. Particularly, the method may comprise: receiving an SS/PBCH block including an SS and a PBCH; detecting an index of a demodulation reference signal (DMRS) sequence for the PBCH; and on the basis of the index of the DRMS sequence, acquiring information relating to a time when an index of the SS/PBCH block and the SS/PBCH block are received, wherein the number of indices of the SS/PBCH block is smaller than or equal to the number of indices of the DMRS sequence, and the indices of the SS/PBCH block are cyclically mapped to the indices of the DMRS sequence.

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).
