Abstract: Provided is a repeater-type radio relay system that can prevent loop interference of radio waves with the same frequency and does not require a frequency for relaying. The radio relay system is provided with one or more optical fibers for relaying an optical communication between a relay-source radio relay apparatus and a relay-destination radio relay apparatus. The relay-source radio relay apparatus has a network-side communication section for communicating with a mobile-communication network side, and an electro-optical signal conversion section of relay source for converting between an electrical signal in the mobile-communication network side received from the network-side communication section and an optical signal propagating through the optical fiber. The relay-destination radio relay apparatus has a terminal-side communication section for wirelessly communicating with the terminal apparatus side, and an electro-optical signal conversion section of relay destination for converting between an electric signal in the terminal apparatus side received from the terminal-side communication section and an optical signal propagating through the optical fiber.

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.

Abstract: An aerial-floating type communication relay apparatus (HAPS) is provided, which can perform a dynamic area control capable of coping with a change of distribution of terminal apparatuses in a service area configured with plural cells formed toward the ground, and that can suppress an increase of time required for area optimization. The aerial-staying type communication relay apparatus (HAPS) estimates positions of plural terminal apparatuses located in a service area, divides plural (L) kinds of antenna parameters of an antenna for service link into plural parameter groups, optimizes the antenna parameters based on estimation results of positions of the plural terminal apparatuses, for each of the parameter groups, and applies, to the antenna for service link, the optimum values of the plural (L) kinds of antenna parameters after completing the optimization for each of the parameter groups.
