Abstract
According to one aspect of the present disclosure, a wireless power receiver for receiving wireless power on the basis of out-band communication is provided. The receiver comprises: a power pick-up circuit configured to receive wireless power from a wireless power transmitter at an operating frequency; and a communication/control circuit configured to perform at least one of in-band communication using the operating frequency and out-band communication using a frequency other than the operating frequency. Here, on the basis of at least one of the received voltage in the power pick-up circuit and a received signal strength indicator (RSSI) of a first signal related to the out-band communication, the communication/control circuit may perform a power interruption procedure for interrupting transmission of the wireless power and a disconnection procedure for releasing the connection of the out-band communication.
