Abstract

L'invention concerne un procédé et un dispositif permettant d'envoyer un PUCCH et concerne un support d'informations lisible pour résoudre le problème technique d'interférence élevée entre des PUCCH. Dans le procédé, un équipement utilisateur peut régler, au moyen d'un mécanisme de compensation de décalage cyclique prédéfini, un décalage cyclique initial indiqué par un équipement de réseau de façon à obtenir un décalage cyclique initial différencié, de telle sorte que différents équipements utilisateurs peuvent utiliser différents décalages cycliques initiaux autant que possible. Les décalages cycliques initiaux utilisés par une pluralité d'équipements utilisateurs présentent une grande distribution différentielle, de telle sorte que même si les séquences de base du PUCCH indiquées par l'équipement de réseau sont identiques, différentes séquences d'envoi de PUCCH peuvent être obtenues en raison de différents décalages cycliques initiaux, ce qui permet de réduire l'interférence entre les PUCCH et d'améliorer les performances du système.
