Abstract:
The present invention relates to a radio access system that supports an unlicensed band, and provides methods for controlling a contention window size (CWS) for performing uplink LBT, methods for effectively utilizing a radio resource even when an uplink data transmission fails, and apparatuses supporting the same. As an embodiment of the present invention, a method for controlling a contention window size (CWS) for transmitting uplink data in a radio access system supporting an unlicensed band by a user equipment, may comprise the steps of: receiving, from an evolved node B, a radio signal including CSW control information indicating information required for controlling a CWS; controlling the CWS on the basis of the CWS control information; performing a listen before talk (LBT) process using the controlled CWS; and transmitting uplink data when a result of the LBT process shows that an unlicensed band is in an idle state.

Claim (Index 7):
A user equipment (UE) adjusting a contention window size (CWS) to transmit uplink data in a wireless access system supporting an unlicensed band, comprising:\n a transmitter; a receiver; and a processor, wherein the processor is configured to control the receiver to receive a radio signal containing CWS adjust information corresponding to information necessary for adjusting a CWS from the eNB, the processor is configured to adjust the CWS based on the CWS adjust information, the processor is configured to control the transmitter and the receiver to perform a listen before talk (LBT) process using the adjusted CWS, and the processor is configured to control the transmitter to transmit the uplink data if an unlicensed band is in an idle state as a result of the LBT process.
