Abstract: An electronic device includes a wireless communication circuit configured to transmit and receive a wireless signal. The electronic device includes a processor operatively connected to the wireless communication circuit. The electronic device includes a memory including instructions. The instructions, when executed by the processor individually or collectively, cause the electronic device to transmit one or more sector sweep frames for beamforming, based on sub-carriers of a millimeter wave band. The instructions, when executed by the processor individually or collectively, cause the electronic device to receive feedback information on the one or more sector sweep frames through the millimeter wave band. The feedback information includes a sector identification of a sector sweep frame received with a strongest signal by an external electronic device among the one or more sector sweep frames. The feedback information includes a sub-carrier index of the sector sweep frame received with the strongest signal.
