description An electronic device includes an antenna, a radio frequency front end (RFFE) connected to the antenna through an electrical path and including a power amplifier (PA). The electronic device includes a control circuit operably coupled to the RFFE and configured to control the output of the PA in order to transmit a sounding reference signal (SRS) based on a first value which is a target transmit (Tx) power value of the SRS to be transmitted to a base station through the antenna, a second value for compensating a power loss caused by the electric path when providing the SRS to the antenna through the electric path, and whether a third value obtained based on the first value and the second value is less than or equal to a reference value or greater than the reference value.
