Abstract: The present invention relates to a wireless access system that supports an unlicensed band, and provides various methods for adjusting a contention window size, methods for determining the time when the adjusted contention window size is applied, methods for distinguishing between a collision and a channel error, and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when it is determined through the performed channel access procedure that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal through the unlicensed band; receiving hybrid automatic repeat and request acknowledgment (HARQ-ACK) information corresponding to the transmission burst; and adjusting the CWS using the number of DTX states in the HARQ-ACK information when the transmission burst is scheduled in a self-carrier scheduling scheme.

Abstract: The present disclosure provides a method for recovering a beam failure in a wireless communication system. The method performed by an user equipment (UE) according to the present disclosure includes receiving a resource configuration in relation to a beam failure recovery request from a base station (BS); receiving a beam reference signal (BRS) used for beam management from the BS; transmitting the beam failure recovery request to the BS using a first resource based on the resource configuration, when a beam failure even is detected; and reporting a measurement result by the beam reference signal to the BS.

Abstract: Embodiments of the present invention relate to a wireless access system supporting a non-licensed band and, more particularly, to methods for transmitting or receiving sub-frame length information indicating the lengths of current and next sub-frames, and apparatuses for supporting the same. As an embodiment of the present invention, a method for receiving sub-frame (SF) length information in a wireless access system supporting a non-licensed band may comprise the steps of: receiving a signal including first SF length information indicating the lengths of one or more of a current SF and a next SF in sub-frame number n−1 (SF # n−1); and receiving one or more of a downlink physical channel and a downlink signal in the SF # n−1 on the basis of the first SF length information. Here, the first SF length information may indicate that the current SF or the next SF is the end SF of a downlink transmission burst in the non-licensed band.
