Abstract
In a mobile communication system comprising: a plurality of first base stations each having a predetermined radio zone, for performing communication with one or more mobile stations; a plurality of second base stations each having a predetermined radio zone and each having a predetermined synchronous area, for performing communication with one or more mobile stations and, in addition, giving a synchronous standard to the plurality of first base stations with the radio zones being in contact with or overlapped with each other within the synchronous area; and an absolute synchronous station for giving a synchronous standard to each of the plurality of second base stations, the second base stations each control the timing of a control channel signal transmitted to the other second base stations based on the timing of a control channel signal transmitted by the absolute synchronous station. The above constitution can realize a mobile communication system and a method for establishing synchronization that can ensure synchronization between a plurality of base stations and can enhance frequency reuse in time division transmission without increasing the occurrence of interference.
