1. A method performed by a first device in a wireless communication system, the method comprising:
deriving an amplitude scaling factor based on a comparison between amplitude distribution of a pilot signal corresponding to a first time resource domain and amplitude distribution of a data signal corresponding to a second time resource domain; and
transmitting, to a second device, the amplitude scaling factor and a physical channel including the pilot signal and the data signal,
wherein the pilot signal is transmitted with a power determined based on the amplitude scaling factor, and
wherein power compensation for the data signal is based on the amplitude scaling factor.
