    • PURPOSE: A method for data communication in wireless power transmission and a device thereof are provided to receive data from a plurality of wireless power reception devices based on one or more sub-carriers within a signal received from a resonant antenna. CONSTITUTION: A resonant antenna(540) wirelessly transmits power to one or more wireless power reception devices. A control unit(540) receives data from each of wireless power reception devices based on one or more sub-carriers within a signal received from the resonant antenna. The data is in-band communication data for the wireless power transmission device and the wireless power reception devices. The control unit detects each envelope line of the one or more sub-carriers. The control unit receives data from each of the wireless power reception device based on logic 1 and logic 0 within the detected envelope line.
