TECHNIQUES FOR ENCODING BEACON SIGNALS IN WIRELESS POWER DELIVERY ENVIRONMENTS

摘要

Embodiments of the present disclosure describe techniques for encoding beacon signals in wireless power delivery environments. More specifically, techniques are disclosed for encoding beacon signals to isolate client devices for wireless power delivery in wireless power delivery environments. The beacon signals can be encoded or modulated with a transmission code that is provided to selected clients in the wireless power delivery environment. In this manner, beacon signals from the select clients can be identified and the corresponding client devices isolated for wireless power delivery. In some embodiments, the transmission code can be a pseudorandom sequence that is used by the wireless power delivery clients to encode transmitted beacon signals.

主权项

1. A wireless power delivery system comprising:
multiple antennas; control circuitry operatively coupled to the multiple antennas, the control circuitry configured to:
establish a wireless communications link with client devices in a wireless power delivery environment via one or more of the multiple antennas;process client-specific information received from the wireless devices to select a set of the client devices for power reception in the wireless power delivery environment and generate beacon transmission scheduling information, wherein the beacon transmission scheduling information includes beacon transmission scheduling assignments for the selected set of client devices; anddirect the one or more antennas to send a beacon transmission scheduling assignment and a transmission code to each of the selected set of client devices, wherein the transmission code is used to isolate signals transmitted from the selected set of client devices.
