Title:

BASE STATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2010/004830

Kind Code:

A1

Abstract:

It is possible to synchronize carrier frequencies between base stations while using a clock generated by a built-in clock generator as a reference signal which decides the carrier frequency of a transmission signal. The base station device is configured so that a radio communication is performed with a terminal device. In the base station device, the accuracy of the OFDM signal carrier frequency is affected by the accuracy of the clock frequency generated by the built-in clock generator (18). The base station device receives an OFDM signal transmitted from other base station while transmission to a terminal devices is halted, estimates the carrier frequency offset of the OFDM signal, and corrects the carrier frequency of the OFDM signal to be transmitted to the terminal device.
