Abstract
A baseband receiving unit receives a signal transmitted from a wireless communication terminal device and including a plurality of symbols arranged in a time direction. A scheduling unit estimates the frequency offset based on a first signal that is for measuring quality and that is mapped to a first symbol placed at a predetermined position in the transmitted signals received with the baseband receiving unit, and a second signal that is for demodulation and that is mapped to a second symbol placed at a position different from the first symbol in the transmitted signal.
