Abstract
The disclosure concerns an inter-base station frame synchronization system for use in a mobile communication system having at least one master base station and a plurality of slave base stations. The master base station is arranged to transmit a control channel signal to the slave base stations located around the master base station in synchronization with a reference frame timing. The slave base stations set a control channel signal observation period. The slave base stations are arranged to generate frame timing based on timings of a received control channel signal from the master base station or other slave base stations when the received control channel signal is received during the control channel signal observation period.
