Abstract
Aspects of the subject disclosure may include, for example, a power receiving unit having a wireless power receiver that receives a wireless power signal from a power transmitting unit. A rectifier circuit rectifies the wireless power signal to generate a rectified power signal in response thereto for charging a battery. A first wireless radio unit exchanges control data with a second wireless radio unit of the power transmitting unit via a wireless control channel, wherein the exchange of control data facilitates establishment of the wireless control channel, establishment of a charging session between the power receiving unit and the power transmitting unit, and control of the charging session between the power receiving unit and the power transmitting unit.
