Near field communication channel initiation via wireless charging channel
First Claim
1. A mobile processor-based system comprising:
- a chargeable power source;
a short-range wireless communications receiver;
a wireless power receiver operatively coupled to the chargeable power source which receives power wirelessly from a wireless power transmitter of a processor-based base station via a wireless charge channel;
at least one nontransitory processor-readable storage medium that stores at least one of processor-executable instructions or data; and
at least one processor communicably coupled to the at least one nontransitory processor-readable storage medium, the short-range wireless communications receiver, and the wireless power receiver, the at least one processor;
sends, via the wireless power receiver, a short-range wireless communications channel request signal to the wireless power transmitter of the processor-based base station over the wireless charge channel;
receives, via the short-range wireless communications receiver, an initiation signal sent from a short-range wireless communications transceiver of the processor-based base station responsive to receipt of the short-range wireless communications channel request signal, the initiation signal initiates a short-range wireless communications channel; and
at least one of;
sends, via the short-range wireless communications receiver, at least one of instructions or data to the short-range wireless communications transceiver of the processor -based base station over the short-range wireless communications channel;
orreceives, via the short-range wireless communications receiver, at least one of instructions or data from the short-range wireless communications transceiver of the processor-based base station over the short-range wireless communications channel.

Abstract
Systems and methods which utilize wireless charging to initiate near field communication (NFC) pairing between mobile systems which utilize wireless charging and wireless charging base stations. Wireless signals sent by a mobile system over a wireless charging channel are used to initiate communication between an NFC reader presented in a base station and a passive NFC tag (or an active NFC tag used in a passive mode) present in the mobile system. Such feature allows the mobile system to act as an initiator for NFC communication without requiring the mobile system to be equipped with an NFC reader. A wireless power receiver of a mobile system may communicate with a wireless power transmitter of a base station using backscatter modulation. Commands of a standard wireless charging protocol may be repurposed to send a request for initiation of an NFC session from a mobile system to a base station.
