Abstract

An interference control method of a power transmitting unit (PTU) includes determining whether the PTU is in an interference environment in which interference by a neighbor PTU occurs, and controlling a communication parameter of either one or both of the neighbor PTU and a power receiving unit (PRU) in response to a result of the determining being that the PTU is in the interference environment.

Claims

1. A control method of an electronic device, the method comprising:

identifying at least one power transmitting device for transmitting wireless power to a power receiving device in a charging area;

establishing a communication connection with the at least one power transmitting device;

generating a signal for controlling power transmission of the at least one power transmitting device; and
