<p>PROBLEM TO BE SOLVED: To maintain synchronization between base stations without influencing communication with a terminal.SOLUTION: A TD-LTE radio base station performs synchronization between base stations by receiving a first downlink synchronization signal from a donor base station, which is another synchronized TD-LTE radio base station. The TD-LTE radio base station comprises: a synchronization detection unit that detects a first downlink synchronization signal received from the donor base station, and outputs synchronization detection timing information; and a control unit that detects synchronization timing difference with the donor base station referring to the synchronization detection timing information after establishing synchronization with the donor base station, and stops transmitting part of a second downlink synchronization signal transmitted by the TD-LTE radio base station in order to refer to the first downlink synchronization signal from the donor base station when correction of the synchronization timing difference is necessary.</p> |
