Abstract
A method is provided for controlling communication in wireless charging. The method comprises: controlling wireless power transfer with a device; receiving a communication signal from the device; generating a jamming signal based on the communication signal from the device; and applying the jamming signal to the communication signal to obtain a jammed communication signal. A device is also provided for controlling communication in wireless charging. The device is configured to control wireless power transfer and receive a communication signal. The device comprises: a jamming circuit configured to generate a jamming signal based on the received communication signal, wherein the device is further configured to apply the jamming signal to the received communication signal to obtain a jammed communication signal.
