    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.

    Abstract: A method and apparatus for transmitting charging power to a wireless power receiver. The method includes detecting the wireless power receiver by applying different detection powers with different power levels; applying a driving power to drive the detected wireless power receiver; receiving a request signal for communication from the detected wireless power receiver using the driving power; determining whether or not to subscribe the detected wireless power receiver to a wireless power network; transmitting, to the detected wireless power receiver, a response signal to the request signal for communication, the response signal indicating whether or not the detected wireless power receiver is subscribed to the wireless power network; and transmitting charging power to the detected wireless power receiver, when the detected wireless power receiver is subscribed to the wireless power network.
