PURPOSE:To relay a data signal stably by sending radio time slot relay information from a master station to a relay station in advance and implementing the relaying based on the relay information. CONSTITUTION:A time division multi-directional multiplex signal processing circuit 9 is provided with a data signal burst signal timing information detection circuit 19; a memory 20, a station number 21, a data signal burst control circuit 22, and an incoming burst relay control circuit 23 comprising an AND circuit and an OR circuit. Then a relay station is operated by three ways of relay operations, that is, fixed relaying, relay inhibit and result of detection of an incoming burst signal from a subordinate station similar to a conventional system corresponding to a radio time slot. Thus, collision of a burst by sending a burst signal in mistake is prevented and a data signal is stably relayed. |
