Method and apparatus for varying a wireless charging category of a wireless power receiver in wireless charging applications
First Claim
1. An apparatus for receiving wireless power, comprising:
- a communication circuit configured to;
transmit a first indication of a first wireless charging category associated with the apparatus,receive an indication of a wireless charging class of a power transmit unit (PTU),compare a power associated with the first wireless charging category to another power associated with the wireless charging class of the PTU,determine if the wireless charging class of the PTU is compatible with a higher wireless charging category than the first wireless charging category based on the comparison, andtransmit a second indication of a second wireless charging category associated with the apparatus based on the determination; and
a coupler configured to receive a level of wireless power corresponding to the second wireless charging category.

Abstract
An apparatus for receiving wireless power is provided. The apparatus a communication circuit configured to transmit a first indication of a first wireless charging category associated with the apparatus. The communication circuit is further configured to receive an indication of a wireless charging class of a power transmit unit (PTU). The communication circuit is further configured to transmit a second indication of a second wireless charging category associated with the apparatus based on the wireless charging class of the PTU being compatible with a higher wireless charging category than the first wireless charging category. The apparatus further comprises a coupler configured to receive a level of wireless power corresponding to the second wireless charging category. The higher wireless charging category indicates an ability to receive a greater amount of wireless power than the first wireless charging category.
