1. A method for receiving a wireless power from a wireless power transmitter, the method performed by a wireless power receiver and comprising:
transmitting, to the wireless power transmitter, a configuration packet comprising first information which is composed of 1 bit,
wherein the first information related to the wireless power receiver informs whether simultaneous incoming and outgoing data stream are supported or not supported;
receiving, from the wireless power transmitter, a capability packet comprising second information which is composed of 1 bit,
wherein the second information related to the wireless power transmitter informs whether simultaneous incoming and outgoing data stream are supported or not supported;
transmitting, to the wireless power transmitter, a first data stream that includes:
(i) an initial auxiliary data control (ADC) data packet opening the first data stream,
(ii) a sequence of auxiliary data transport (ADT) data packets including a first actual message, and
(iii) a final ADC data packet closing the first data stream; and
receiving, from the wireless power transmitter, a second data stream that includes:
(i) an initial ADC data packet opening the second data stream,
(ii) a sequence of ADT data packets including a second actual message, and
(iii) a final ADC data packet closing the second data stream,
wherein the wireless power receiver transmits the first data stream and simultaneously receives the second data stream, based on the first information and the second information,
wherein the wireless power receiver transmits a first ADT data packet to the wireless power transmitter,
wherein based on the wireless power receiver receiving an acknowledge (ACK) in response to the first ADT data packet, the wireless power receiver transmits a second ADT data packet to the wireless power transmitter,
wherein, based on the second ADT data packet being transmitted, an ADT header is toggled from an even-number to an odd-number,
wherein the toggled ADT header is transmitted with the second ADT data packet, and
wherein, between transmitting the initial ADC data packet related to the first data stream and transmitting the final ADC data packet related to the first data stream, the wireless power receiver transmits at least one control error packet related to control information for a wireless charging to the wireless power transmitter.
