Abstract
An exemplary embodiment includes a method of communication between a wireless power receiver to a wireless power transmitter. The method includes receiving, by an antenna of the wireless power receiver, radio frequency (RF) signals from the wireless power transmitter, wherein the wireless power receiver substantially matches an impedance of the wireless power transmitter. The method further includes, while receiving the RF signals from the wireless power transmitter: (a) determining whether a communication criterion is satisfied, and (b) in accordance with a determination that the communication criterion is satisfied, introducing an impedance mismatch between the wireless power receiver and the wireless power transmitter that causes a portion of the RF signals to be reflected by the antenna as a modulated signal, wherein the wireless power transmitter is configured to receive and interpret the modulated signal without using a separate communication radio.
