<P>PROBLEM TO BE SOLVED: To provide a communication system capable of enhancing the accuracy of time synchronization among base station devices. <P>SOLUTION: A synchronizing signal for taking synchronization among a plurality of base station devices and storing first synchronization accuracy index information capable of specifying the accuracy of the synchronization time in the base station device of the transmission origin is received. Also, second synchronization accuracy index information capable of specifying the accuracy of the synchronization time at which the present apparatus takes the synchronization is stored. Then, when the accuracy of the synchronization time predetermined by the first synchronization accuracy index information is better than the accuracy of the synchronization time predetermined by the second synchronization accuracy index information, the base station device 1 corrects the timing of transmitting the synchronizing signal from the present device on the basis of the reference time stored in the synchronizing signal storing the first synchronization accuracy index information. <P>COPYRIGHT: (C)2010,JPO&INPIT |
