Abstract

A base station apparatus includes a wireless communication unit, a wired communication unit, and a communication timing correction unit. If the wireless communication unit fails to receive a synchronization signal from another base station apparatus at given reception timing, the wired communication unit transmits a synchronization state confirmation signal for confirming a synchronization state between the base station and another base station apparatus, and receives a synchronization state response signal including a determination result of the synchronization state. The communication timing correction unit corrects a communication timing based on the synchronization state response signal.
