METHOD AND SYSTEM OF RADIO FREQUENCY (RF) POWER TRANSMISSION IN A WIRELESS NETWORK
First Claim
1. A method of radio frequency (RF) power transmission in a wireless network including multiple wireless stations, the method comprising:
- generating control signals for switching a receiving wireless station between a power reception mode and a data reception mode, the control signals providing switching information including information about which of the modes to switch to, and information about timing of the switching; and
switching the wireless station between power reception and data reception modes based on the control signals;
wherein in the data reception mode, the receiving wireless station processes an RF transmission from a sending wireless station as a data communication, and in the power reception mode the receiving wireless station processes the RF transmission as energy radiation for powering the receiving wireless station.

Abstract
A method and system of radio frequency (RF) power transmission among multiple wireless stations is provided. Control signals for switching a receiving station between a power reception mode and a data reception mode are generated. The control signals provide switching information about which of the modes to switch to, and timing of the switching. In the data reception mode, the receiving station processes an RF transmission from a sending station as a data communication. In the power reception mode the receiving station processes the RF transmission as energy radiation for powering the receiving station. One type of control signal for power mode switching is generated at the MAC layer of a receiving station and sent to the PHY layer of that station for power mode switching. Another type is RTS/CTS control signal exchanged between the sending and receiving stations.
