Title:
BASE STATION DEVICE AND COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2013225925
Kind Code:
A
Abstract:

To provide a base station device capable of synchronizing a plurality of base station devices with high accuracy if a predetermined synchronization signal is not received.

The base station device includes a communication timing correction unit, and a storage unit for storing a base station device candidate capable of a determination request target of a synchronous state, along with the information of priority order. In the priority order, priority is given to another base station device in an upper hierarchy than a base station device in the same hierarchy as the base station device of interest. If a synchronization signal cannot be received, a synchronous state confirmation signal to confirm a synchronous state is transmitted to a base station device determined on the basis of the priority order, and communication timing is corrected based on a synchronous state response signal.
