Le procédé fait appel aux étapes suivantes : la réception d'informations de configuration envoyées par un dispositif côté réseau, les informations de configuration activant une fonction de saut de transmission de liaison montante d'un terminal ; et à condition qu'un canal partagé de liaison montante physique (PUSCH) et qu'un canal de commande de liaison montante physique (PUCCH) présentent un chevauchement de ressources dans le domaine temporel, la détermination, selon la priorité d'un principe de priorité cible et la fonction de saut de transmission de liaison montante, d'un comportement de transmission des UCI portées sur le PUCCH, le principe de priorité cible comprenant un principe de priorité de canal logique ou un principe de de priorité de contrôle d'accès au support (MAC).
