FIELD: radio engineering, communication.
SUBSTANCE: determination unit (117) selects the number of divisions in the frequency domain of a signal transmitted from wireless communication terminal device. In this case the determination unit (117) increases the number of divisions in the frequency domain of the signal transmitted from the wireless communication terminal device as the number of pilot blocks included in the transmitted signal increases. Furthermore, a scheduling unit (118) schedules allocation of frequency resources of the divided transmitted signal according to the number of divisions determined by the determination unit (117).
EFFECT: high efficiency of frequency diversity while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a signal transmitted from a wireless communication terminal device.
