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: Disclosed, in the present invention, are a method for transmitting, by a base station, a downlink signal in a wireless communication system supporting an unlicensed band, and a device for supporting the same. More particularly, in accordance with one embodiment of the present invention, when acknowledgment timing of each terminal (for example, an interval length from a time point of receiving downlink data to a time point of transmitting acknowledgment information for the downlink data) is set flexibly (or independently), a base station may determine a reference downlink resource for contention window size (CWS) adjustment by considering the acknowledgement timing and perform downlink signal transmission by adjusting CWS on the basis of the acknowledgment information received for the reference downlink resource.
