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 is a method of receiving a synchronization signal block (SSB) by a user equipment in a wireless communication system. The method includes receiving a first SSB from a serving cell, receiving a second SSB from a neighbor cell, obtaining time information of the first SSB based on a physical broadcasting channel (PBCH) included in the first SSB, and obtaining an index of the second SSB using the time information of the first SSB.
