Disclosed are a wireless communication base station device and a division number determination method that improves the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit (117) determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit (117) increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit (118) schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit (117).

Cette invention se rapporte à un dispositif de station de base de communication sans fil et à un procédé de détermination de nombre de divisions qui permet d'améliorer l'effet de diversité de fréquence tout en maintenant une précision d'estimation de canal indépendamment du nombre de divisions dans le domaine fréquentiel d'un signal de transmission provenant d'un dispositif de terminal de communication sans fil. Une unité de détermination (117) détermine le nombre de divisions dans le domaine fréquentiel d'un signal de transmission en provenance d'un dispositif de terminal de communication sans fil. Ici, l'unité de détermination (117) augmente le nombre de divisions dans le domaine fréquentiel du signal de transmission provenant du dispositif de terminal de communication sans fil lorsque le nombre de blocs pilotes inclus dans le signal de transmission augmente. En outre, une unité de planification (118) planifie lattribution aux ressources de fréquence du signal de transmission divisé selon le nombre de divisions déterminé par l'unité de détermination (117).
