Electronic device for performing communication based on beamforming and method therefor

An electronic device, comprising:

• at least one memory;
• an antenna array including N number of antenna elements arranged to form M number of beams;
• and
• at least one processor operatively connected to the antenna array,
• wherein a memory stores instructions, when executed by the at least one processor, causes the at least one processor to:
