Abstract: Embodiments described herein provide a method for wireless power transmission of reconfigurable power levels. A wireless power receiver is used to receive power from a wireless power transmitter according to a negotiated power level. The wireless power receiver determines whether a re-negotiation condition is met at the wireless power receiver. The wireless power receiver then sends, to the wireless power transmitter, a re-negotiation request for an updated power level different from the negotiated power level. The wireless power receiver receives, from the wireless power transmitter, an acknowledgement that acknowledges the updated power level, and then operates to receive power from the wireless power transmitter according to the updated power level.

Abstract: In accordance with embodiments of the present invention, data is modulated for transmission phase modulation. A method of transmitting data in a wireless power transmitter, includes transmitting a wireless power signal; encoding data to be transmitted into symbols; determining a phase shift to represent the symbols; and phase modulating the wireless power signal with the phase shift. A method of receiving data in a wireless power receiver includes receiving a wireless power signal that includes a phase modulated data signal; determining a period of each cycle of the wireless power signal; providing a running average over N?1 cycles of the wireless power signal, where N represents the number of cycles of the wireless power signal in which each phase modulation is provided; and decoding the data from the running average.
