PROBLEM TO BE SOLVED: To improve the communication efficiency by allowing a radio repeater to distinguish a transmission output for a radio base station from a transmission output for a radio terminal equipment so as to prevent a deteriorated frequency utility efficiency due to interference or the like thereby containing many more numbers of subscribers into the same area. SOLUTION: The system is provided with a radio base station 103, a radio terminal equipment 107, and a radio repeater 104 used by the radio base station 103 and the radio terminal equipment 107 for their communication, the radio repeater 104 includes an antenna 105 used to send a radio wave to the radio base station 103 and the radio terminal equipment 107 and the radio repeater 104 is provided with a transmission output variable device 106. The arrival range of a radio wave from the radio repeater 104 to the base station 103 is differentiated from the arrival range of a radio wave from the radio repeater 104 to the radio terminal equipment 107 for each transmission slot so as to reduce the influence of the frequency and the transmission slot used for the communication with the radio terminal equipment 107 onto other surrounding radio base stations. |
