1. A method for transferring a wireless power in a wireless power transfer system, the method performed by a wireless power transmitter and comprising:
receiving a configuration packet from a wireless power receiver in a configuration phase,
wherein the configuration packet related to the wireless power receiver includes information on whether functionality for out-of-band communication is supported;
transmitting a capability packet to the wireless power receiver in a negotiation phase,
wherein the capability packet related to the wireless power transmitter includes information on whether functionality for the out-of-band communication is supported;
receiving a first specific request (SRQ) packet related to end of the negotiation phase from the wireless power receiver in the negotiation phase; and
transmitting an ACK for the first SRQ packet to the wireless power receiver,
wherein the wireless power transmitter initiates a connection to the out-of-band communication based on transmitting the ACK for the first SRQ packet.
