Abstract: Provided are a method for transmitting uplink control information (UCI) of a terminal in a wireless communication system and the UE using the method. The method includes determining a number of coded symbols for the UCI transmission and transmitting the UCI on a physical uplink shared channel (PUSCH) based on the number of coded symbols. The number of coded symbols is determined among a first value based on a payload size of the UCI and an offset value and a second value based on a radio resource control (RRC) signal.

Abstract: The present disclosure relates to a wireless access system supporting an unlicensed band, and provides methods for transreceiving discovery reference signals and devices supporting same. A method for a terminal receiving a discovery reference signal (DRS) in a wireless access system supporting an unlicensed band, according to one embodiment of the present disclosure, may comprise the steps of: receiving an upper layer signal including parameters indicating a multimedia broadcast multicast service single frequency network (MBSFN) subframe; receiving a setting for a discovery measurement timing configuration (DMTC) section, which is a time section during which the DRS can be transmitted; and receiving the DRS within the DMTC section, wherein when a first subframe belonging to the DMTC section is configured as the MBSFN subframe and the DRS is transmitted from the first subframe, an MBSFN configuration may not be applied to the MBSFN subframe.

Abstract: Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.
