COMMUNICATION METHOD AND APPARATUS IN WIRELESS RECHARGING SYSTEM
First Claim
1. A method, of performing communication between a wireless power transmitter and a wireless power receiver, comprising:
- performing load detection by detecting wireless power provided by the wireless power transmitter being applied to the wireless power receiver;
setting up a common channel having a predetermined first frequency for establishing a connection with the wireless power receiver, which is performed by the wireless power transmitter;
establishing the connection with the wireless power receiver using the common channel;
determining, from among available channels, a selection channel having an optimal condition for communicating with the wireless power receiver and a predetermined second frequency through use of the common channel;
; and
performing data transmission and reception with the wireless power receiver through the selection channel.
