摘要:
A receiving method of a wireless power receiver comprising: receiving the power having a first frequency band from a wireless power transmitter that transmits power having the first frequency (S201, S203); determining (S207) if a power receiving state of the first frequency band is abnormal; detecting whether the wireless power transmitter transmits power having a second frequency band when the power receiving state of the first frequency band is abnormal (S211); and receiving the power having the second frequency band from the wireless power transmitter that transmits power having the second frequency (S213, S215, S217), wherein, while receiving the power having the first frequency band, the wireless power receiver transmits a power signal to the wireless power transmitter through in-band communication (S205), and wherein detecting whether the wireless power transmitter transmits power having the second frequency band is done through out-of-band communication (S209).
