    Abstract: Disclosed are a method for transmitting an uplink control channel in a wireless communication system and an apparatus for the same. Particularly, the method comprises the steps of: receiving allocation of a resource region including one or more symbols for transmission of an uplink control channel; and mapping uplink control information and a reference signal to each specific resource group unit in the allocated resource region, wherein the specific resource group unit may comprise a first resource element having the reference signal mapped thereto and second resource elements having the at least one piece of uplink control information mapped thereto, the second resource elements may be arranged adjacent to the first resource element, and the second resource elements may be multiplexed according to orthogonal cover codes in a clockwise or counter-clockwise direction.

    Abstract: A method for performing uplink transmission is discussed. The method performed by a wireless communication device includes receiving first information, related to a Physical Uplink Control Channel (PUCCH) configuration, wherein the first information includes second information related to frequency hopping, wherein the first information includes third information on a plurality of PUCCH resources, and wherein the second information is included for each of the plurality of the PUCCH resources; determining at least one PUCCH resources among the plurality of the PUCCH resource; and transmitting PUCCH signal based on the second information and the at least one of the plurality of the PUCCH resources.

    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.
