Abstract

L'invention concerne un procédé d'affectation de ressources d'amélioration de couverture pour un équipement utilisateur, une station de base et un équipement utilisateur. Le procédé comprend : la détection, par une station de base, de l'existence ou non de demandes de communication d'un équipement utilisateur (UE) correspondant à un premier grade d'amélioration de couverture; et l'ajustement, par la station de base, de ressources d'amélioration de couverture allouées pour le premier grade d'amélioration de couverture selon le résultat de détection. Dans le procédé fourni par ce mode de réalisation, en détectant l'existence ou non de demandes de communication d'un UE correspondant à un premier grade d'amélioration de couverture, une station de base ajuste les ressources d'amélioration de couverture allouées pour le premier grade d'amélioration de couverture selon le résultat de détection. Ainsi, la station de base peut ajuster la configuration des ressources d'amélioration de couverture à temps et de façon flexible selon les demandes d'amélioration de couverture d'un UE correspondant à un premier grade d'amélioration de couverture, ce qui réduit le gaspillage des ressources d'amélioration de couverture.
