2 Claims

1. A method for receiving, by a wireless power receiver, wireless power, the method comprising:

receiving digital ping in a ping phase;

transmitting a configuration packet of the wireless power receiver in a configuration phase after the ping phase;

performing a negotiation of a power transfer contract in a negotiation phase after the configuration phase; and

receiving the wireless power from a wireless power transmitter based on the power transfer contract in a power transfer phase after the negotiation phase,

wherein the configuration packet includes an out-of-band field,

wherein the out-of-band field is composed of 1 bit, and

wherein, based on the out-of-band field having a value of 1, the out-of-band field indicates that the wireless power receiver supports out-of-band communication, and

based on the out-of-band field having a value of 0, the out-of-band field indicates that the wireless power receiver does not support the out-of-band communication.
