Original Abstract Submitted

A method for transferring, by a wireless power transmitter, wireless power, the method including performing digital ping in a ping phase; receiving a configuration packet of a 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 transferring the wireless power to the power receiver based on the power transfer contract in a power transfer phase after the negotiation phase, wherein the configuration packet includes a negotiation field, wherein the negotiation field related to whether the negotiation phase is supported is composed of 1 bit, wherein the configuration packet includes a 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.
