Abstract

La présente invention concerne le domaine des communications et permet de résoudre le problème de l'art antérieur selon lequel un conflit se produit dans des ressources occupées par une rétroaction ACK/NACK d'un équipement d'utilisateur sur une sous-trame de liaison descendante. L'invention concerne un procédé, un dispositif et un système de transmission de données. Une solution particulière comprend les étapes suivantes : un premier dispositif détermine dans une n-ième ressource temporelle une première ressource PUCCH et une seconde ressource PUCCH, la largeur de la ressource de fréquence entre la première ressource PUCCH et la seconde ressource PUCCH étant inférieure ou égale à la largeur de bande de travail du premier dispositif, le premier dispositif utilise la première ressource PUCCH pour transmettre des informations de commande correspondant à une m1-ième sous-trame de liaison descendante à une station de base, et utilise la seconde ressource PUCCH pour transmettre des informations de commande correspondant à une m2-ième sous-trame de liaison descendante à la station de base. L'invention est destinée à être utilisée dans la transmission d'informations.
