An electronic device comprising: a housing; a first antenna; a second antenna; a first wireless communication circuit electrically connected to the first antenna and configured to transmit and/or receive a first signal having a first frequency between 500 MHz and 6 GHz; a first power modulator included in the first wireless communication circuit or connected to the first wireless communication circuit, and configured to provide the first wireless communication circuit with a first voltage based on envelope tracking, ET, or average power tracking, APT; a second wireless communication circuit electrically connected to the second antenna and configured to transmit and/or receive a second signal having a second frequency between 500 MHz and 6 GHz; a second power modulator included in the second wireless communication circuit or connected to the second wireless communication circuit and configured to provide the second wireless communication circuit with a second voltage based on the ET or the APT; at least one processor operatively connected to the first wireless communication circuit and the second wireless communication circuit; and a memory operatively connected to the at least one processor or coupled with the at least one processor, CHARACTERISED IN THAT the memory stores one or more instructions that, when executed, cause the at least one processor to: receive uplink resource information indicating a number of resource blocks allocated to the electronic device from a base station, via the first wireless communication circuit; when the number of uplink resource blocks indicated by the uplink resource information is greater than or equal to a defined number, identify an electric field associated with the first wireless communication circuit, wherein the electric field associated with the first wireless communication circuit is identified based on a reference signal received power, RSRP, received from the base station or an error rate of data received from said base station; when the identified electric field is greater than or equal to a threshold value, cause the second power modulator to provide a voltage based on the APT or the ET and cause the first power modulator to reduce a maximum transmission power. a housing;
