Abstract:
The present invention relates to a wireless access system supporting an unlicensed band, and to methods for performing uplink listen before talk (LBT) on multiple carriers, and a device supporting the same. According to one embodiment of the present invention, 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.

Claim (Index 14):
The UE according to  claim 8 , wherein even though the first LBT is indicated for the remaining CCs, the second LBT is performed in the remaining CCs.
