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: Disclosed is a method by which a terminal reports channel status information to a base station in a wireless communication system. Particularly, the method comprises the steps for attempting to detect a reference signal repeatedly transmitted multiple times for each reference signal transmission unit; setting the reference signal transmission unit as an effective reference resource for the channel state information when the reference signal is detected in a preset section within the reference signal transmission unit; measuring the channel state information at the effective reference resource; and reporting the channel state information to the base station.

Abstract: A method is provided for determining transmit power of an uplink control channel of a user equipment to which two cells having different uplink (UL)-downlink (DL) configurations are assigned. A larger value between N1, the number of downlink subframes corresponding to a subframe n of a first cell having a first UL-DL configuration, and N2, the number of downlink subframes corresponding to a subframe n of a second cell having a second UL-DL configuration is chosen. A parameter value is determined based on the chosen value.

Abstract: A method is provided for performing a random access procedure by a user equipment (UE) in a wireless communication system supporting coverage enhancement. The UE repeatedly transmits a physical random access channel (PRACH) signal, determines a random access radio network temporary identifier (RA-RNTI) corresponding to the PRACH signal using system frame number (SFN) information, wherein time index information and frequency index information are not used for determining the RA-RNTI, and monitors downlink control information masked by the determined RA-RNTI. The time index information indicates a subframe starting the repeated transmission of the PRACH signal, the frequency index information indicates a frequency index of the PRACH signal transmitted in the starting subframe, and the SFN information indicates a radio frame starting the repeated transmission of the PRACH signal.
