PURPOSE:To dispense with a base station and to enable retransmission even between mobile stations by rereceiving a signal by providing a receiver for necessary signals and a control device to make a request for retransmission if there exists a reception error in signals addressed to the self-station. CONSTITUTION:The mobile station inputs transmitted information from a transmitted information input terminal 1, and converts it into a transmitted signal by a control part 22, and this signal is given error correction information by an error correcting coding part 3 after passing through a retransmission processing part 17. After this signal is modulated by a modulating part 4, it is turned into a high frequency signal synchronously with a transmission timing signal 5 outputted from the control part 22 by a transmitting part 6, and it is transmitted through an antenna sharing part 8 and an antenna 9. Then, in the course of the transmission of the self-station, an attenuator 16 is inserted at the transmission timing signal 5 in order to avoid a leakage path to a receiving system. The quantity of this attenuator has a level suitable to a receiving level in the case that the transmitted signal to the self-station need be received, and it is made lower than the lowest receiving sensitivity in the case that the signal need not be received. Then, the mesh type network of TDMA communication is constituted by determining previously a system that each station transmits the signal sccessively.
