Wireless power transmitter, electronic device and controlling method thereof

A control method of a wireless power transmitter, the control method comprising:

• controlling, by a processor of the wireless power transmitter, an antenna of the wireless power transmitter, to transmit a plurality of detection powers in a plurality of directions, respectively, the plurality of detection powers comprising a first detection power and a second detection power, the first detection power including a first direction information and identification information of the wireless power transmitter, the first detection power being transmitted in a first direction, the second detection power including a second direction information and the identification information of the wireless power transmitter, the second detection power being transmitted in a second direction different from the first direction;
• controlling, by the processor, a communication circuit of the wireless power transmitter, to receive a communication signal including the first direction information and the identification information of the wireless power transmitter from an electronic device which received the first detection power;
• and
• based on receiving the communication signal, controlling, by the processor, to transmit power for charging in the first direction,
• wherein the communication signal further includes identification information of the electronic device.

An electronic device comprising:

• an antenna;
• a communication circuit;
• and
• a processor,
• wherein the processor is configured to:
• control the antenna to receive, from a first wireless power transmitter, a first detection power including first direction information and first identification information of the first wireless power transmitter,
• control the antenna to receive, from a second wireless power transmitter, a second detection power including second direction information and second identification information of the second wireless power transmitter,
• select, based on the first detection power and the second detection power, a wireless power transmitter between the first wireless power transmitter and the second wireless power transmitter,
• control the communication circuit to transmit, to the selected wireless power transmitter, direction information and identification information included in a detection power received from the selected wireless power transmitter, and
• control the antenna to receive, from the selected wireless power transmitter, power for charging.
