Abstract: The present invention relates to a wireless access system supporting an unlicensed band. According to this disclosure, a method by which a terminal performs LBT in a wireless access system supporting an unlicensed band and multiple carriers can comprise the steps of: receiving, from a base station, each of uplink grants for scheduling uplink channels on two or more component carriers (CCs); randomly selecting a first CC on which a first LBT is to be performed from among the two or more CCs; performing the first LBT on the selected first CC: and performing a second LBT on the remaining CCs among the two or more CCs, wherein the first LBT can be a random back-off-based LBT for performing a random back-off by a random back-off counter value, and the second LBT can be a channel sensing-based LBT for sensing a channel during a predetermined time interval before uplink transmission.

Abstract: The present invention relates to a wireless access system supporting an unlicensed band, various methods for adjusting a contention window size, methods for performing a carrier sensing process in a single engine and a multi-engine, and an apparatus supporting the same. As one embodiment of the invention, a method for adjusting a contention window size (CWS) in a wireless access system supporting an unlicensed band may comprise: a step of setting a contention window size (CWS) necessary for performing a channel access process for each of priority classes; a step of performing a channel access process for a particular priority class in a channel in an unlicensed band on the basis of the set CWS; a step of performing a downlink transmission related to the particular priority class if it is determined that the channel in the unlicensed band is in an idle state as a result of the channel access process; and a step of making adjustments for all CWS' of priority classes if a triggering event, which relates to a downlink transmission and increases or reduces the CWS for the particular priority class, occurs.
