## 2. ABSTRACT

A method and apparatus are provided for operating a wireless power transmitter. The method includes controlling the wireless power transmitter to wirelessly transmit power for charging a first power receiver, and while transmitting the power, receiving a search signal from a second power receiver, transmitting a search response signal corresponding to the search signal, and receiving, from the second power receiver, a request join signal including at least one piece of information associated with a power requirement of the second power receiver. Based on identifying that the wireless power transmitter is capable of providing the power having an amount greater than the power requirement of the second power receiver, the method further includes transmitting a charge start command to the second power receiver.
