¿µ¹®³»¿ë¿ä¾à The standard specifies a TDD type control technique for RF beamforming wireless power transmission. It defines communication connection between PTU and PRU using Legacy communication module in 2.4GHz, 5.8GHz or ISM band and the message format for wireless power transmission control. Furthermore, it
defines the simultaneous use of both TDD-based PTU / PRU beacon exchange and wireless power transfer control using Guard Band. The standard summarizes the overall scenario for beamforming wireless power transmission control, DPS slot allocation scheme in TDD, timing diagram information and priority calculation .
