A transmission of a sounding reference signal by an electronic device is provided. A method of an electronic device includes transmitting a signal via a first antenna subset including at least one of a plurality of antennas, measuring an emission environment of the plurality of antennas, using the signal, determining at least one antenna to be used for transmitting a sounding reference signal (SRS), based on the emission environment, and transmitting the SRS via the at least one determined antenna. The emission environment includes a strength of a reflected signal that corresponds to the signal and is reflected by the first antenna subset, or a strength of a reception signal that corresponds to the signal and is received by a second antenna subset including at least one remaining antenna.
