METHOD AND ELECTRONIC DEVICE FOR CONTROLLING TRANSMISSION POWER FOR MULTI-BEAM TRANSMISSION

A disclosed mobile electronic device may be configured to: identify multiple beams including a first beam and a second beam for communication with at least one base station; when the first beam and the second beam correspond to the same first direction, identify a third beam which corresponds to a direction differing from the first direction and has a strength of a signal received from the at least one base station, the strength being equal to or greater than a designated value; when the identification of the third beam fails, apply, to the first beam and the second beam, a power back-off for multiple beams corresponding to the same direction, so as to perform communication with the at least one base station; and when the third beam is identified, change the second beam to the third beam and perform communication with the at least one base station without applying the power back-off for multiple beams corresponding to the same direction and by using the first beam and the third beam. Various other embodiments identified through the specification are also possible.
