Abstract

La présente invention se rapporte au domaine des communications. L'invention concerne un procédé et un dispositif de transmission d'informations, susceptibles de résoudre le problème qui fait que, lorsqu'un équipement d'utilisateur envoie des données en liaison montante à un dispositif de réseau, le dispositif de réseau présente une consommation énergétique excessivement importante et occasionne un important brouillage aux autres dispositifs de réseau. La solution particulière est la suivante: un dispositif de réseau détermine une première ressource temps-fréquence, envoie une signalisation de programmation à un équipement d'utilisateur sur la première ressource temps-fréquence, et reçoit des données en liaison montante émises par l'équipement d'utilisateur sur la première ressource temps-fréquence. La présente invention est utilisée dans la transmission d'informations.
