Reduced jamming between receivers and wireless power transmitters

摘要

Exemplary embodiments are directed to reducing jamming caused by radiated fields generated by wireless power transmitters. Exemplary embodiments include detecting a jamming condition of a wireless power receiving device resulting from a radiated field from a wireless power transmitter of a charging device. Such embodiments include synchronizing the wireless power coupling with communication of the wireless power receiving device. Synchronizing wireless power coupling may include wireless power coupling at a first level when the wireless power receiving device is expected to receive a signal on a communication channel. Synchronizing wireless power coupling may further include coupling at a higher rate when the wireless power receiving device is not expected to receive a signal on the communication channel.

1. A method of receiving power from a wireless power charger, comprising:
receiving power wirelessly from the wireless power charger at a first wireless communication device at a first power level that can charge the first wireless communication device; monitoring interference over a communication channel of the first wireless communication device caused by a field generated by the wireless power charger; and receiving power wirelessly from the wireless power charger at a second power level that can charge the first wireless communication device if the monitored interference over the communication channel of the first wireless communication device is greater than a threshold, the second power level less than the first power level.
