Abstract: An example electronic device includes a communication processor; at least one radio frequency integrated circuit (RFIC) connected to the communication processor; at least one radio frequency front-end (RFFE) circuit connected to the at least one RFIC and configured to process a transmission signal; and a plurality of antennas connected through the at least one RFFE circuit. The communication processor may control to transmit, at a first time point when a reference signal is to be transmitted through a first antenna from among the plurality of antennas, the reference signal to a base station through the first antenna; and transmit, at a second time point when the reference signal is to be transmitted through a second antenna from among the plurality of antennas, a reference signal adjusted at least based on a signal received through the second antenna to the base station through the first antenna.
