<p><P>PROBLEM TO BE SOLVED: To provide a technique capable of synchronization between base stations while easily enabling to use cooperative transmission in a base station apparatus which performs communication by frequency division duplex. <P>SOLUTION: The base station apparatus includes a down signal receiving unit 12 for receiving a down signal from another base station apparatus and a synchronization processing unit 5b for acquiring a known signal included in the down signal from the other base station apparatus and performing synchronization between base stations with the other base station apparatus based on the known signal. The synchronization processing unit 5b performs synchronization between the base stations so that the transmission timing of the known signal included in the own down signal is matched with the transmission timing of the known signal included in the down signal of the other base station apparatus. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
