Claim Text:
1. A base station apparatus that communicates with another base station apparatus by a time-sharing system, the base station apparatus comprising: a wireless transceiver that communicates with the another base station apparatus through a wireless network; a wired transceiver that communicates with the another base station apparatus through a wired network; a storage unit, the storage unit including a program, execution of the program determines a communication timing of a communication signal communicated by the wireless transceiver and corrects the communication timing of the communication signal communicated by the wireless transceiver, wherein if the wireless transceiver fails to receive a synchronization signal from the another base station apparatus at a given reception timing, the wired transceiver transmits to the another base station apparatus a synchronization state confirmation signal for confirming a synchronization state between the base station apparatus and the another base station apparatus, the synchronization state confirmation signal including at least one of information on a transmission channel and a transmission slot through which a synchronization signal is transmitted from the base station apparatus, and the wired transceiver receives from the another base station apparatus a synchronization state response signal including information on a temporal deviation of the base station apparatus relative to the another base station apparatus, and execution of the program corrects the communication timing of the communication signal communicated by the wireless transceiver based on the synchronization state response signal received by the wired transceiver.
