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 communication system. In particular, the present invention relates to a method and an apparatus for receiving data, by a terminal, in a wireless communication system, the method comprising the steps of: receiving a PDCCH; receiving a PDSCH corresponding to the PDCCH in a subframe including CSI-RS resource available in a cell; and demodulating the PDSCH. If a predetermined condition is satisfied, demodulation of the PDSCH is performed on the assumption that the PDSCH is not transmitted in the CSI-RS resource available in the cell, and if the predetermined condition is not satisfied, the demodulation of the PDSCH is performed on the assumption that the PDSCH can be transmitted in the CSI-RS resources available in the cell.

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.
