Abstract

L'invention concerne un procédé de communication de terminal et un équipement d'utilisateur, utilisés pour résoudre le problème rencontré dans l'état antérieur de la technique, où la consommation d'énergie d'un équipement d'utilisateur distant est excessivement élevée en raison de la nécessité pour l'équipement d'utilisateur distant de détecter tous les SCI dans une ressource de PSCCH de façon à déterminer un SCI dont l'équipement d'utilisateur distant a besoin. Le procédé comporte les étapes consistant à: faire déterminer, par un premier équipement d'utilisateur, au moins un second équipement d'utilisateur associé ou connecté au premier équipement d'utilisateur; faire regrouper, par le premier équipement d'utilisateur, le ou les seconds équipements d'utilisateur selon une règle de regroupement spécifiée; faire partitionner, par le premier équipement d'utilisateur, les ressources de transmission du premier équipement d'utilisateur selon le regroupement, et déterminer des informations de configuration de ressources de transmission du premier équipement d'utilisateur; et faire transmettre, par le premier équipement d'utilisateur, les informations de configuration de ressources de transmission du premier équipement d'utilisateur.
