Abstract: An example electronic device includes a first antenna module, a first transmitter, a first communication processor, a second antenna module, a second transmitter, and a second communication processor. The first communication processor receives a state of the second communication processor, sets a first allocated total exposure ratio (TER) value based on a state of the first communication processor and the state of the second communication processor, sets transmission limit power of each antenna of a plurality of antennas included in the first antenna module based on the first allocated TER value, and sets transmit power of each antenna of the plurality of antennas included in the first antenna module based on the transmission limit power.
