Abstract

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.

First claim

What is claimed is:

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

2. The method of claim 1 , wherein the out-of-band communication is defined in a different communication system other than a transmission and reception system of the wireless power.

3. The method of claim 2 , wherein the out-of-band communication corresponds to a short range communication protocol.

4. The method of claim 3 , wherein the out-of-band communication is Bluetooth.

5. A wireless power transmitter, comprising:
a converter related to transferring wireless power to a wireless power receiver; and
a communicator/controller related to controlling transfer of the wireless power,
wherein the wireless power transmitter:
performs digital ping in a ping phase;
receives a configuration packet of the wireless power receiver in a configuration phase after the ping phase;
performs a negotiation of a power transfer contract in a negotiation phase after the configuration phase; and
transfers the wireless power to the wireless power receiver 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.

6. The wireless power transmitter of claim 5 , wherein the out-of-band communication is defined in a different communication system other than a transmission and reception system of the wireless power.

7. The wireless power transmitter of claim 6 , wherein the out-of-band communication corresponds to a short range communication protocol.

8. The wireless power transmitter of claim 7 , wherein the out-of-band communication is Bluetooth.
