L'invention porte sur un procédé pour utiliser une ressource et sur un dispositif de communication. Le procédé comprend : dans la mesure où une ressource de transmission en liaison montante périodique est disponible pour un processus d'accès aléatoire et un processus de transmission de données en liaison montante, l'utilisation de la ressource de transmission en liaison montante pour transmettre des données dans un processus cible, le processus cible comprenant au moins l'un du processus d'accès aléatoire et du processus de transmission de données en liaison montante. La présente invention accroît la fiabilité d'utilisation de ressources.
