L'invention concerne un procédé, un équipement utilisateur et un système destinés à émettre des données montantes, permettant de réduire un volume de données d'émission montante, cela réduisant la puissance d'émission des données montantes. Une solution particulière consiste à : recevoir une commande de contrôle d'autorisation d'une station de base, et déterminer une valeur d'autorisation de service conformément à la commande de contrôle d'autorisation; conformément à la valeur d'autorisation de service, à la puissance propre restante et à un volume de données à émettre, déterminer une taille d'un bloc d'émission; et si la taille du bloc d'émission et la taille d'un bloc d'émission maximum correspondant à la valeur d'autorisation du service respectent une condition prédéfinie, utiliser une politique par défaut prédéfinie du canal de contrôle pour envoyer les données à émettre vers la station de base. Les modes de réalisation de la présente invention sont principalement utilisés dans un processus d'émission de données montantes.
