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 1):
A method of adjusting a contention window size (CWS), which is controlled by a user equipment (UE) to transmit uplink data in a wireless access system supporting an unlicensed band, the method comprising:\n receiving a radio signal containing CWS adjust information corresponding to information necessary for adjusting the CWS from an enhanced Node-B (eNB); adjusting the CWS based on the CWS adjust information; and performing a listen before talk (LBT) process using the adjusted CWS; and transmitting the uplink data, if the unlicensed band is in an idle state as a result of the LBT process.
