초록 ▼

A radio communication system having a plurality of base stations, each forming a radio zone, and a plurality of mobile stations connected to those base stations in a time-division multiplexing manner via digital radio circuitry that time-division multiplexes a plurality of time slots for those base stations, comprising at least one supervising radio transmitting station for transmitting a reference synchronizing signal to a first and a second base station of the plurality of base stations via radio circuitry, the reference synchronizing signal being used in establishing synchronous relationship between the first and second base stations, receiving section installed in each of the first and second base stations, for receiving the reference synchronizing signal from the supervising radio transmitting station via radio circuitry, and synchronizing section installed in each of the first and second base stations, for establishing synchronous time-slot relationship in the digital circuitry between those base synchronizing stations and the mobile stations, based on the reference signal received by the receiving section.
