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.

Abstract: Provided are a method for determining a listen-before-talk (LBT) priority class by a terminal in a wireless communication system and a device supporting same. The terminal can receive, from a network, mapping information between a logical channel and an LBT priority class and determine a particular LBT priority class on the basis of the received mapping information and a logical channel having data to be transmitted.

Abstract: A method for transmitting multiple uplink control information (UCI) on a physical uplink control channel (PUCCH) in a wireless communication system is disclosed. More specifically, the method performed by a user equipment (UE) includes receiving, from a base station, first control information related to the PUCCH for transmitting the multiple UCI; determining a first parameter representing a number of coded bits for the multiple UCI based on the first control information, wherein the multiple UCI includes channel state information (CSI) including at least one of a first part or a second part; determining a size of the first part based on the first parameter and second control information related to the size determination of the first part; and transmitting, to the base station, the multiple UCI on the PUCCH.

Abstract: According to the present invention, a first physical downlink control channel (PDCCH) and a second PDCCH can be transmitted to user equipment. A first physical downlink data channel (PDSCH) corresponding to the first PDCCH, and a second PDSCH corresponding to the second PDCCH can be transmitted to the user equipment. When the first PDSCH has a lower decoding priority than the second PDSCH, and the decoding timing of the first PDSCH and the decoding timing of the second PDSCH overlap, the user device may decode the second PDSCH and not the first PDSCH at the decoding timing, and transmit information with respect to the first PDSCH as first ACK/NACK information. As a reply to the first ACK/NACK information, a third PDCCH not having a corresponding PDSCH may be transmitted to the user equipment.
