1. A mobile electronic device comprising:
a first antenna module comprising at least one array antenna;
a second antenna module comprising at least one array antenna;
at least one processor operatively connected to the first antenna module and the second antenna module; and
memory electrically connected to the at least one processor,
wherein the memory stores instructions that, when executed, cause the at least one processor to:
identify a plurality of beams comprising a first beam and a second beam for communicating with at least one base station using the first antenna module,
determine, when the first beam and the second beam correspond to a same antenna module, a third beam, which corresponds to a direction different from a direction of the first beam and of which a received signal strength from the at least one base station exceeds a specified value, is available,
based on a determination that the third beam is unavailable, communicate with the at least one base station by applying, to the first beam and the second beam, power backoff, and
based on a determination that the third beam is available, change the second beam for the third beam and communicate with the at least one base station using the first beam and the third beam without applying the power backoff.
