¿µ¹®³»¿ë¿ä¾à This standard specifies scheduling control between transmission and reception terminals for simultaneous information/power transmission/reception technology such as allocating time and frequency divided data transmission and power transmission to individual slot GTS using the DSME method defined in IEEE 802.15.4-2015. In addition, a static power transmission method when multiple PRUs and multiple PTUs are connected and a negotiated power transmission method when a single PRU and a single PTU are connected are also defined. Finally, this standard suggest simultaneous information/power transmission technology that combines frequency separation and channel adaptation method to ensure ISM band wireless communication operation, wireless power transmission mode separation and distributed cooperative charging to increase power transmission efficiency.
