Abstract
This disclosure provides systems, methods and apparatuses for a new communication technique between a wireless power transmission apparatus and a wireless power reception apparatus. The new communication technique may be more efficient for communication of a feedback parameter or other control information compared to a legacy packet-based digital communication technique. The new communication technique may use a pulse width modulation (PWM) signal as an analog representation of a feedback parameter or other control information. In some implementations, the PWM communication technique in this disclosure can be used for a variety of control or feedback information from the wireless power reception apparatus to the wireless power transmission apparatus. Furthermore, in some implementations, the PWM communication technique may be used for feedforward information from the wireless power transmission apparatus to the wireless power reception apparatus.
