PURPOSE:To prevent the generation of beat disturbance at a base station and the deterioration of an S/N ratio by controlling the actuation start time of a repeating station and by inhibiting the actuation start, i.e., the transmission to the base station of an unnecessary repeating station. CONSTITUTION:Receivers Rx1 and Rx1' receive signals from a mobile station, and receivers Rx2 and Rx2' receive signals from an adjacent repeater. Circuits N and N' have operation characteristics that a relay B is operated slow when the intensity of an electric field is small or fast when large. When the mobile station Z sends a signal for communication with a base station, it is received by repeating stations X and Y at the same time, but both the stations X and Y normally have a difference in incoming electric field. When the incoming electric field of the station X is greater than that of the station Y, a transmitter Tx is actuated to perform transmission. At the station Y, on the other hand, the incoming electric field SSI is small, the operation of a relay B' is delayed, and a relay D' is operated by a signal from the adjacent station to the base station while a transmitter is not driven. |
