Synchronization between radio base stations in a mobile radio communication system is established by including in a control signal (Fig. 5) transmitted at a predetermined time interval from each of the radio base stations, synchronization establishing information (SE) indicating whether the radio base station has established synchronization (first state) or not (second state) determining, in a receiving radio base station, whether the synchronization establishing information included in the received control signal indicates the first state or the second state establishing synchronization with the transmitting radio base station, when the information indicates the first state and setting, the synchronization establishing information included in the control signal transmitted from the receiving radio base station to indicate the first state. <IMAGE> |
