METHOD AND APPARATUS FOR PROVIDING WIRELESS CHARGING POWER TO A WIRELESS POWER RECEIVER
First Claim
1. A method for wirelessly transmitting charging power to a wireless power receiver by a wireless power transmitter, the method comprising:
- 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.

12. A wireless power transmitter for transmitting charging power to a wireless power receiver, the wireless power transmitter comprising:
-
a resonator for transmitting charging power to the wireless power receiver; a controller for detecting the wireless power receiver by applying detection powers with different power levels and controlling the resonator to apply a driving power to drive the detected wireless power receiver; and a communication unit for receiving, from the detected wireless power receiver using the driving power, a request signal for communication, wherein the controller determines whether or not to subscribe the detected wireless power receiver to a wireless power network, controls the communication unit to transmit, to the 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 controls the resonator to transmit the charging power to the detected wireless power receiver, when the detected wireless power receiver is subscribed to the wireless power network. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of detecting a wireless power receiver by a wireless power transmitter, the method comprising:
-
applying a first detection power to a resonator of the wireless power transmitter for a first period of time; applying a second detection power to the resonator; identifying a load change that exceeds a predetermined threshold, while the first detection power or the second detection power is applied; and detecting the wireless power receiver, based on the identified load change.
