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: Various embodiments provide methods whereby a terminal and a base station transmit and receive signals in a wireless communication system, and devices for supporting same. Comprised are the steps of: transmitting a physical uplink shared channel (PUSCH) to a base station; receiving, from the base station, hybrid automatic repeat request-acknowledgment (HARQ-ACK) information on the PUSCH before transmitting the PUSCH a number of times, the number of times being the number of repeated transmissions corresponding to the PUSCH; and determining whether or not to end the transmission of the PUSCH on the basis of the received HARQ-ACK information. Accordingly, the terminal can effectively control unnecessarily repeated transmission of uplink data, and the power consumption of the terminal can be reduced.
