Method for pairing with external device using beam and electronic device therefor

An electronic device comprising:

• a display;
• a wireless communication circuitry configured to provide wireless communication;
• an antenna array including a plurality of antenna elements used for beamforming;
• and
• at least one processor operatively connected to the wireless communication circuitry and the antenna array, wherein the processor is configured to:
• display a plurality of sectors on the display,
• detecting a selection of a sector from among the plurality of sectors,
• form and transmit a beam corresponding to a direction of the electronic device based on a start of a service and a beam identification (ID) allocated to the selected sector,
• monitor reception of a response signal corresponding to the beam from at least one external device, and
• perform pairing with the at least one external device based on at least a part of the response signal if the response signal is received.
