Le procédé sert à la transmission d'un canal PUCCH d'un équipement d'utilisateur dans un système de transmission CoMP (multipoint coordonné) et consiste à : sélectionner un paramètre parmi des paramètres pertinents afin de déterminer une séquence de base et des ressources physiques pour la transmission du canal PUCCH, les paramètres pertinents comprenant un paramètre commun à des cellules et un paramètre spécifique à un utilisateur ; et notifier le paramètre sélectionné à l'équipement d'utilisateur. Au moyen du mode de réalisation de la présente invention, un côté réseau peut sélectionner un paramètre pour un équipement d'utilisateur afin de déterminer une séquence de base et des ressources d'un canal PUCCH sur la base des conditions réelles ou d'un objectif d'optimisation de sorte à éviter des interférences ou de sorte à rendre aléatoires des interférences, et peut améliorer l'efficacité d'utilisation du canal PUCCH.
