WIRELESS CHARGING SYSTEM FOR A MOBILE COMMUNICATION TERMINAL, A METHOD THEREFOR AND THE MOBILE COMMUNICATION TERMINAL THEREFOR, CONCERNED WITH CHARGING POWER IN A BATTERY OF THE MOBILE COMMUNICATION TERMINAL BY ITSELF BY USING MICROWAVES PROPAGATING IN FREE SPACE

摘要

PURPOSE: A wireless charging system for a mobile communication terminal, a method therefor and the mobile communication terminal therefor are provided to convert a microwave, which propagates in free space, into a power and charge the power in a battery of the mobile communication terminal by itself. CONSTITUTION: A detecting unit(113) detects a carrier from a certain frequency in an RF(Radio Frequency) transmitted from a base station(210) according to the control of a control unit(111). A converting unit(114) converts the detected carrier into a power. A charging unit(115) charges the converted power in a battery(116). An RF transceiver(112) transmits an output level adjustment requesting signal to the base station(210) according to the control of the control unit(111). The base station(210) has an output level adjusting unit(211). The output level adjusting unit(211) receives the output level adjustment requesting signal from the RF transceiver(112), and adjusts an output level of a carrier frequency to transmit to a mobile communication terminal the carrier frequency in which the power level is up-adjusted.
