Disclosed are a wireless communication apparatus and frequency hopping method which minimize the change in the instantaneous power distribution characteristics of the time waveform of transmission signals when a plurality of channels are multiplexed by frequency division. At a terminal (200), a mapping unit (212) maps the PUCCH to frequency resources of a first slot, maps the PUSCH to frequency resources, among the frequency resources of the first slot, separated exactly by predetermined frequency spacing (B) from the frequency resources to which the PUCCH is mapped, and cyclically shifts the frequencies so as to map the PUCCH and PUSCH to frequency resources, within an IDFT or IFFT bandwidth, of a second slot while maintaining the predetermined frequency spacing (B), thereby allowing frequency hopping of the PUCCH and PUSCH between the first slot and the second slot.

La présente invention concerne un appareil de communication sans fil et un procédé de saut de fréquence qui minimise le changement dans les caractéristiques de distribution de puissance instantanée de la forme d'onde temporelle de signaux de transmission lorsqu'une pluralité de canaux est multiplexée par répartition en fréquence. Au niveau d'un terminal (200), une unité de mappage (212) mappe le PUCCH à des ressources de fréquence d'un premier créneau, mappe le PUSCH à des ressources de fréquence, parmi les ressources de fréquence du premier créneau, séparé exactement par un espace de fréquence prédéfini (B) à partir des ressources de fréquence auxquelles le PUSCH est mappé, et décale cycliquement les fréquences de manière à mapper le PUSCH et le PUCCH aux ressources de fréquence, dans une largeur de bande IDFT ou IFFT, d'un second créneau tout en maintenant l'espace de fréquence prédéfini (B), permettant ainsi le saut de fréquence du PUCCH et du PUSCH entre le premier et le second créneau.
