RADIO COMMUNICATION SYSTEM

Japanese Patent JP2014171124

A

PROBLEM TO BE SOLVED: To provide a radio communication system that is able to prevent same wave interference even in the case where base station areas are overlapped and is easy-to-use in a radio communication system in which a plurality of base stations transmit signals on a common channel.SOLUTION: A plurality of base stations have timing synchronization, periodic transmission timing of a signal is preset to each base station so that transmission of signals of the respective base stations will not collide, and each base station transmits the signal at its own station's transmission timing. In signals transmitted by each base station, there is a first signal (10 frames in an occupied section) and a second signal (two frames each in a shared section) with a transmission time shorter than the first signal. It is configured such that any one base station has transmission timing of the first signal and the other base stations have the second transmission timing in a period when the transmission timing of each base station makes a circuit.

JP7077516	A transmitter network with at least two transmitters, a transmitter in the transmitter network, and a receiver in this transmitter network.
JP2001516168	INDUSTRIAL APPLICABILITY: A method and an apparatus for synchronizing the carrier frequency of a mobile unit with the carrier frequency of a fixed station.
