Abstract:
The present invention relates to a wireless access system supporting an unlicensed band and a carrier sensing method, and more specifically, to methods for performing listen before talk (LBT), methods for selecting a representative carrier, methods for transmitting data bursts, and a device for supporting same. A method for a base station transmitting a data burst in a wireless access system supporting an unlicensed band and carrier aggregation, according to one embodiment of the present invention, may comprise the steps of: selecting a first component carrier (CC) from among at least two CCs; performing a listen before talk (LBT) process during which a random backoff is carried out by the first CC; and transmitting the data burst from the first CC; and transmitting the data burst from the first CC, when the first CC is in an idle state after the LBT process, wherein the step of selecting the first CC may be performed every time a specific number of data bursts have been transmitted or at specific time intervals.

Claim (Index 7):
The base station according to  claim 6 , wherein the processor performs a sensing procedure in a second CC included in the at least two CCs by controlling the transmitter and the receiver, to determine whether the second CC is in the idle state, and transmits a data burst in the second CC by controlling the transmitter, if the second CC is in the idle state after the sensing procedure.
