BASE STATION DEVICE, AND INTER-BASE-STATION SYNCHRONIZATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a base station device capable of highly accurately executing inter-base-station synchronization.

SOLUTION: This base station device BS1 is provided with: a sampling section 11 for obtaining a plurality of sampling waves by dividing one part of a received wave from a base station device BS2 into a plurality of waves at a time width corresponding to a transmission cycle of preamble and sampling them; an averaging processing section 12 for adding the plurality of sampling waves sampled by the sampling section 11 and applying averaging processing to obtain a detected wave; and a timing detecting section 13 for detecting a transmission timing of the preamble wave on the basis of the detected wave obtained by the averaging processing section 12. The base station device BS1 executes inter-base-station synchronization on the basis of the transmission timing of the preamble wave detected by the timing detecting section 13.
