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.

Claim (Index 7):
A base station for adjusting a contention window size (CWS) in a wireless access system supporting an unlicensed band, the base station comprising:\n a transmitter; and a processor configured to support CWS adjustment, wherein the processor is configured to configure a CWS required to perform a channel access procedure for each of priority classes, to perform the channel access procedure for a specific priority class based on the configured CWS in a channel of the unlicensed band, to perform a downlink transmission related to the specific priority class by controlling the transmitter, when the channel of the unlicensed band is determined as an idle state as a result of the channel access procedure, and to adjust CWSs for all of the priority classes when a triggering event for increasing or decreasing a CWS for the specific priority class is occurred, wherein the triggering event is related to the DL transmission.
