摘要： 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.

摘要： A system and method for discovering and tracking communication directions is disclosed herein. In one embodiment, communication directions for two devices with asymmetric antenna systems are discovered. In one embodiment, a contention access period (CAP) is partitioned into an association CAP and a regular CAP, either of which may be further partitioned into sub-CAPs corresponding to different reception directions. In one embodiment, an association request command is transmitted by a device at different association sub-CAPs to train a transmission direction of the device. In one embodiment, further training is performed to find the best communication directions, as collisions may occur when association request commands are transmitted at different association sub-CAPs.
