Abstract:
A wireless power reception method of a wireless power receiver for receiving power from a wireless power transmitter is disclosed. The wireless power receives a connection signal for identifying the wireless power receiver from the wireless power transmitter; transmitting a response signal in response to the connection signal to the wireless power transmitter; negotiating a power transmission condition with the wireless power transmitter; and receiving the power using resonance frequency band according to the negotiated power transmission condition. Furthermore, frequency band for exchanging information used for the power reception is different from the resonance frequency band. In addition, the negotiating of the power transmission condition comprises: receiving first state information of the wireless power transmitter from the identified wireless power transmitter, and transmitting second state information to the wireless power transmitter, the second state information being determined from the wireless power receiver based on the first state information of the wireless power transmitter.
