摘要
An inter-base station frame synchronization system for use in a mobile communication system includes at least one master base station and a plurality of slave base stations. The master base station is provided with time information receiving means for receiving time information with high precision externally supplied, reference frame timing generation means for generating a reference frame timing on the basis of the time information, and first control channel signal transmission means for transmitting a control channel signal to the slave base stations in synchronism with the reference frame timing. Each of the slave base stations is provided with its own station frame timing generation means for generating an its own station frame timing on the basis of the reception timing of one of the control channel signals transmitted from the master base station and other slave base stations, and second control channel signal transmission means for transmitting a control channel signal in synchronism with the its own station frame timing.
