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.
