APPARATUS AND METHOD FOR WIRELESS CHARGING
First Claim
1. A method for wireless charging in an apparatus that wirelessly receives power, the method comprising:
- transmitting, by the apparatus, a wireless power supply apparatus search signal;
receiving a wireless power supply apparatus search response signal;
recognizing multiple apparatuses for wirelessly supplying power, based on the wireless power supply apparatus search response signal;
sending a request for wirelessly supplying power, to a first apparatus for wirelessly supplying power among the multiple apparatuses;
receiving a cooperative charging enable signal from the first apparatus;
sending a request for cooperative charging to a second apparatus for wirelessly supplying power, based on the cooperative charging enable signal from the first apparatus;
receiving a cooperative charging permission signal from the second apparatus;
receiving first power and second power from the first apparatus and the second apparatus, respectively; and
performing wireless charging using the first power and the second power.
