Abstract: Provided is a wireless-power transfer apparatus capable of efficiently supplying a predetermined power for each of plural terminal apparatuses. A wireless-power transfer apparatus comprises a radio processing section for transmitting a signal for wireless power transfer to each of the plural terminal apparatuses via plural beams, by a beamforming for forming the plural beams against the plural terminal apparatuses simultaneously or at staggered times, an information acquisition section for acquiring terminal information including location information of a current location of a terminal apparatus for each of plural terminal apparatuses, and a control section for controlling the beamforming so that a signal for wireless power transfer is received at a predetermined reception power in each of plural terminal apparatuses, based on terminal information of each of plural terminal apparatuses.

Abstract: Provided is a system comprising a base station and a terminal apparatus that communicate with each other by selectively using plural radio resources, which is capable of supplying a power to the terminal apparatus using a communication-unused radio resource between the base station and the terminal apparatus. The base station generates a transmission signal including a dummy signal for wireless power transfer using a communication-unused radio resource that is not used for communication among plural radio resources, and transmits the generated transmission signal to the terminal apparatus. The terminal apparatus receives the transmission signal including the dummy signal transmitted from the base station, and outputs an electric power of the reception signal as a reception power. A battery may be charged using the reception power.
