Wireless power receiving device, wireless power transmitting device, and method for calibrating power using the same

In a wireless power receiver receiving wireless power from a wireless power transmitter, the wireless power receiver configured to:

• transmit a first received power packet including a first estimated received power value for a first calibration data point to the wireless power transmitter;
• receive ACK in response to the first received power packet from the wireless power transmitter;
• transmit a second received power packet including a second estimated received power value for a second calibration data point to the wireless power transmitter;
• receive ACK in response to the second received power packet from the wireless power transmitter;
• transmit a new second received power packet including a third estimated received power value for a third calibration data point to the wireless power transmitter;
• and
• receive ACK in response to the new second received power packet from the wireless power transmitter.

• receive ACK in response to the first received power packet from the wireless power transmitter;
• transmit a second received power packet including a second estimated received power value for a second calibration data point to the wireless power transmitter;
• receive ACK in response to the second received power packet from the wireless power transmitter;
• and
• based on change of a target operating point, transmit a new second received power packet including a third estimated received power value for a third calibration data point to the wireless power transmitter or transmit a new first received power packet including a new first estimated received power value for anew first calibration data point and a new second received power packet including a new second estimated received power value for a new second calibrated data point to the wireless power transmitter.
