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.

Abstract: According to various embodiment, an electronic device may include at least one communication processor, an RFIC, a power amplifier, and at least one modulator configured to provide the power amplifier with a supply voltage set for a first unit of time in a first mode or in a second unit of time shorter than the first unit of time in a second mode. The at least one communication processor may be configured to control the at least one modulator to provide the supply voltage according to the second mode and to switch from the second mode to the first mode when a variation in a voltage associated with a first element for providing the supply voltage is greater than or equal to a threshold magnitude while the supply voltage is provided to the power amplifier according to the second mode. Other various embodiments are possible as well.

Abstract: An electronic device includes a first antenna that transmits/receives a signal in a first frequency band, a second antenna that transmits/receives a signal in a second frequency band, a first wireless communication circuit connected with the first antenna, a second wireless communication circuit connected with the second antenna, at least one processor connected with the first and second wireless communication circuits, and a memory. The memory stores instructions that cause the processor to output a first signal with a first power to control the first wireless communication circuit to output the first signal through the first antenna, and output the first signal with a power, which is obtained by backing off from the first power as much as a first backoff value, to control the second wireless communication circuit to output a second signal through the second antenna while controlling the first wireless communication circuit to output the first signal.
