Abstract
A method in a wireless power transfer system can include, in response to a digital ping initiated by a wireless power transmitter, transmitting to the wireless power transmitter during a ping phase, a response signal. The method can further include transmitting, to the wireless power transmitter during a configuration phase, a configuration packet including first control information related to whether a wireless power receiver supports an authentication function to authenticate the wireless power transmitter; receiving, from the wireless power transmitter during a negotiation phase, a capability packet including second control information and a potential power value of the wireless power transmitter; and transmitting, to the wireless power transmitter during a power transfer phase, an authentication request message.
