Abstract

La présente invention se rapporte à un procédé de contrôle de la puissance sur la liaison montante pour un paquet. L'invention se rapporte d'autre part à un dispositif adapté pour réaliser une fonction de contrôle en temps réel de la puissance sur la liaison montante pour un paquet. La solution technique de la présente invention consiste : à créer un paramètre de contrôle de la puissance sur la liaison montante; et à transporter le paramètre de contrôle de la puissance sur la liaison montante à l'intérieur d'un bloc de données de contrôle de la liaison radio (RLC, Radio Link Control) sur la liaison descendante en vue de la transmission à une station mobile. La présente invention se rapporte d'autre part à un procédé de contrôle de la puissance sur la liaison montante pour un paquet et à un dispositif adapté pour réaliser une fonction de contrôle différentiel de la puissance sur la liaison montante pour un paquet. Cette autre solution technique de la présente invention consiste à créer un paramètre de contrôle différentiel de la puissance sur la liaison montante. Ledit paramètre comprend : un paramètre de contrôle de la puissance en vue de contrôler la puissance sur la liaison montante pour un bloc de données, et un paramètre de contrôle de la puissance en vue de contrôler la puissance sur la liaison montante pour un bloc de contrôle vide. L'autre solution technique de la présente invention consiste d'autre part : à transmettre le paramètre de contrôle différentiel de la puissance sur la liaison montante à une station mobile.
