On the other hand, the power control message corresponding to a response to the detection signal may be a message indicating strength of the wireless power signal received by the wireless power receiver 200. For example, the wireless power receiver 200 may transmit a signal strength packet 5100 including a message indicating the received strength of the wireless power signal as a response to the detection signal as illustrated in
The wireless power transmitter 100 may receive a response message to the detection signal to find the wireless power receiver 200, and then extend the digital detection process to enter the identification and configuration state 630. In other words, the wireless power transmitter 100 maintains the power signal at a specific operating point subsequent to finding the wireless power receiver 200 to receive a power control message required in the identification and configuration state 630.
However, if the wireless power transmitter 100 is not able to find the wireless power receiver 200 to which power can be transferred, then the operation phase of the wireless power transmitter 100 will be returned to the selection state 610.
3) Identification and Configuration State
