Abstract:
1. A base station device that performs communication using a downlink signal composed of a plurality of communication unit areas arranged along a time axis, each communication unit area having a certain time length, the plurality of communication unit areas including a communication unit area containing a specification signal used for communication control and a communication unit area not containing the specification signal, the base station device comprising: a reception unit that receives a downlink signal from another base station device; and a synchronization processing unit that performs inter-base-station synchronization, by obtaining the downlink signal from the another base station device received by the reception unit and by causing a transmission timing of the communication unit area in the downlink signal of the base station device to coincide with that of the another base station device, wherein the synchronization processing unit performs the inter-base-station synchronization such that a transmission timing of the specification signal in the downlink signal of the base station device is different from a transmission timing of the specification signal in the downlink signal of the another base station device, and the transmission timing of the specification signal in the downlink signal of the base station device are offset, by a time period corresponding to a predetermined number of the communication unit areas, from the transmission timing of the specification signal in the downlink signal of the another base station device.
