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: A method for transmitting channel state information (CSI) by a user equipment in a wireless communication system is discussed. The method includes receiving a transmission burst; measuring the CSI based on the transmission burst; and transmitting the measured CSI, wherein the transmission burst is received in at least a first time resource and a second time resource, wherein the first time resource is configured as a first number of orthogonal frequency divisional multiplexing (OFDM) symbols, wherein the second time resource is configured as a second number of OFDM symbols, wherein the first number is smaller than the second number, and wherein the first time resource is considered to be an invalid time resource for the CSI.
