Abstract

L'invention concerne un procédé qui consiste à diviser des ressources de communication en une pluralité de groupes de ressources en vue de la transmission d'au moins un signal de référence ; déterminer un modèle de mesure spécifique d'utilisateur pour chaque équipement utilisateur d'une pluralité d'équipements utilisateurs ; attribuer la pluralité des équipements utilisateurs à l'un des groupes de ressources ; et transmettre une indication du groupe de ressources attribué et du modèle de mesure spécifique d'utilisateur à chacun de la pluralité des équipements utilisateurs pour configurer la pluralité des équipements utilisateurs afin que ceux-ci mesurent et notifient des informations de qualité à l'aide de la ressource de communication au sein du groupe de ressources attribué.
