1. A system comprising a base station and a terminal apparatus capable of communicating with each other by selectively using plural radio resources,
wherein the base station comprises:
a communication-signal processing section for generating a transmission signal including a dummy signal for wireless power transfer, the dummy signal being modulated at a symbol point selected for wireless power transfer among plural symbol points of a digital modulation method for downlink communication to the terminal apparatus, by using a communication-unused radio resource that is not used for communication among the plural radio resources in a downlink radio frame for communication to the terminal apparatus; and
a radio processing section for transmitting the transmission signal including the dummy signal for wireless power transfer to the terminal apparatus, and
wherein the terminal apparatus comprises:
a radio processing section for receiving the transmission signal including the dummy signal transmitted from the base station; and
a power output section for outputting an electric power of a reception signal that is obtained by receiving the transmission signal including the dummy signal, as a reception power, and
wherein the terminal apparatus is wirelessly power-supplied using the communication-unused radio resource in the downlink radio frame for communication to the terminal apparatus.
