Abstract: The present invention relates to a wireless access system that supports an unlicensed band, and provides various methods for adjusting a contention window size, methods for determining the time when the adjusted contention window size is applied, methods for distinguishing between a collision and a channel error, and devices for supporting the same. As an embodiment of the present invention, a method for adjusting a contention window size in a wireless access system supporting an unlicensed band may comprise the steps of: performing a channel access procedure; when it is determined through the performed channel access procedure that a serving cell (Scell) in the unlicensed band is in an idle state, transmitting a transmission burst including a downlink signal through the unlicensed band; receiving hybrid automatic repeat and request acknowledgment (HARQ-ACK) information corresponding to the transmission burst; and adjusting the CWS using the number of DTX states in the HARQ-ACK information when the transmission burst is scheduled in a self-carrier scheduling scheme.

Abstract: The present invention provides a method by which an MTC terminal measures channel state information (CSI), a method for transmitting CSI, and apparatuses supporting the same. A method by which the MTC terminal feeds back CSI in a wireless access system supporting machine type communication (MTC), according to one embodiment of the present invention, comprises the steps of: receiving allocation information on a limited MTC bandwidth allocated to the MK terminal; calculating CSI; and feeding back the CSI. Here, the CSI can include MTC wideband channel state information (MTC W-CQI) for the limited MTC bandwidth.

Abstract: In the present invention, a part of a first demodulation reference signal sequence generated on the basis of a basic subcarrier interval (hereinafter, a first subcarrier interval) is used for a second subcarrier interval which is K times the first subcarrier interval. Values selected one for every K from among values constituting the first demodulation reference signal sequence may be used as values constituting a second demodulation reference signal sequence for the second subcarrier interval.
