WIRELESS COMMUNICATION SYSTEM, INTER-BASE-STATION SYNCHRONIZATION METHOD AND BASE STATION

摘要

To enable a base station apparatus (asynchronized base station), which cannot receive any sync pulses from a GPS or from a time synchronization server, to perform an operation that is equivalent to the synchronization with a base station apparatus (synchronized base station) having received a sync pulse. There are included a synchronized base station that uses a received sync pulse to synchronize itself with a base station in a different cell; an asynchronized base station that is located in the cell of the synchronized base station; and a terminal. The asynchronized base station comprises a means that determines a reception timing difference, at the terminal, between a transport signal transmitted by the synchronized base station and a transport signal transmitted by the asynchronized base station; and a means that controls the transmission timing of the asynchronized base station such that the reception timing difference becomes equal to or less than a predetermined value.
