Abstract: Provided are a method and an apparatus for transmitting data in an unlicensed band. The apparatus determines whether a wireless medium is idle by performing a clear channel assessment (CCA) during a plurality of continuous CCA slots in the unlicensed band. When the wireless medium is idle, the apparatus transmits a reservation signal to occupy the wireless medium during a plurality of continuous reservation slots until transmission of a data burst begins.

Abstract: The present invention relates to a Vehicle-to-X (V2X) communication method performed by a terminal in a wireless communication system. The method comprises: determining priority of information related to the V2X communication; selecting a transmission time interval (TTI) on the basis of the priority; and transmitting the information on the basis of the selected TTI. If the information related to the V2X communication is information having high priority, a first TTI is selected, and if the information related to the V2X communication is information having relatively lower priority than the information having high priority, a second TTI is selected.

Abstract: A wireless communication system is disclosed. More particularly, disclosed herein are a method including receiving downlink scheduling information on a PDCCH, the downlink scheduling information comprising resource indication information (RI), selecting a first PUCCH resource set from among a plurality of PUCCH resource sets based on a size of the control information, and transmitting the control information using a PUCCH resource corresponding to the RI in the first PUCCH resource set, wherein, when a control information size supported by the first PUCCH resource set is less than or equal to X (>=1) bits, the PUCCH resource is determined using one of a first scheme and a second scheme, and wherein, when the control information size supported by the first PUCCH resource set is greater than X bits, the PUCCH resource is determined using only the second scheme, and an apparatus therefor.

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.

Abstract: Provided are a method and apparatus for transmitting data in an unlicensed band. The device determines a downlink reception end time and an uplink transmission start time at which the uplink transmission starts in the unlicensed band. If the interval between the downlink reception end time and the uplink transmission start time is equal to or less than a threshold value, the device abandons the uplink transmission.
