Abstract
Official abstract text for this publication.
While a clock generated by a built-in clock generator is used as a reference signal for determining a carrier frequency of a transmit signal, carrier frequency synchronization is achieved between base stations. A base station device is configured to perform wireless communication with a terminal device. In the base station device, accuracy of a carrier frequency of an OFDM signal is affected by accuracy of a clock frequency generated by a built-in clock generator 18 . The base station device receives an OFDM signal transmitted from another base station device while transmission to the terminal device is stopped, estimates a carrier frequency offset of the OFDM signal, and corrects a carrier frequency of an OFDM signal to be transmitted to the terminal device.
First claim
Opening claim text (preview).
The invention claimed is: 1. A base station device configured to perform wireless communication of an OFDM signal with a terminal device and including a built-in clock generator that generates an operating clock, in which accuracy of a carrier frequency of the OFDM signal is affected by accuracy of a clock frequency generated by the built-in clock generator, the base station device comprising: means for receiving a radio signal transmitted from another base station device while tr…
