Dynamic control of wireless power for a variable load

A method for dynamic power control performed by a wireless power reception apparatus, comprising:

• transmitting, to a wireless power transmission apparatus, configuration data plurality of corresponding reference load states in a single message prior to a power transfer phase, the configuration data including a plurality of reference control parameters for a plurality of corresponding reference load states of the wireless power reception apparatus, wherein each reference load state represents a different load voltage and load power setting of the wireless power reception apparatus;
• transmitting, to the wireless power transmission apparatus, a load state of the wireless power reception apparatus, wherein the load state refers to a matching reference load state of the plurality of corresponding reference load states;
• and
• receiving wireless power from the wireless power transmission apparatus that is based, at least in part, on the plurality of reference control parameters for the matching reference load state.

A wireless power transmission apparatus, comprising:

• a communication unit to:
• receive, from a wireless power reception apparatus, configuration data in a single message prior to a power transfer phase, the configuration data including a plurality of more reference control parameters for a plurality of corresponding reference load states of the wireless power reception apparatus, wherein each reference load state represents a different load voltage and load power setting of the wireless power reception apparatus, and
• receive, from the wireless power reception apparatus, a load state of the wireless power reception apparatus, wherein the load state refers to a matching reference load state of the plurality of corresponding reference load states;
• a primary coil to transmit wireless power to the wireless power reception apparatus using an operating control parameter;
• and
• a controller to control the operating control parameter based, at least in part, on the plurality of reference control parameters for the matching reference load state.
