Abstract: A method and an electronic device are provided for controlling power of the electronic device. Uplink resource information allocated to the electronic device from a base station is received via a first wireless communication circuit configured to transmit and/or receive a first signal of 6 GHz or less. A power modulator of the electronic device controls a power of at least one wireless communication circuit, from among the first wireless communication circuit and a second wireless communication circuit configured to transmit and/or receive a second signal of 6 GHz or less, with APT based on at least the number of uplink resource blocks indicated by the uplink resource information.
