Abstract

L'invention concerne un procédé de transmission d'informations, un équipement d'utilisateur, et une station de base. Le procédé s'applique à un MTC. Le procédé comprend les étapes consistant à : envoyer des données MTC à une station de base ; lorsque des informations de rétroaction d'état de transmission envoyées par la station de base sont reçues durant une période de temps prédéterminée, déterminer un état de transmission des données MTC en tant qu'un premier état de transmission ; et lorsque les informations de rétroaction d'état de transmission envoyées par la station de base ne sont pas reçues durant la période de temps prédéterminée, déterminer l'état de transmission des données MTC en tant qu'un second état de transmission. Un équipement d'utilisateur peut déterminer un état de transmission d'une transmission de données MTC en liaison montante selon que des informations de rétroaction d'état de transmission envoyées par une station de base sont, ou non, reçues durant une période de temps prédéterminée. Comparé à l'état de la technique, le procédé peut réduire le volume d'informations de rétroaction d'état de transmission et donc économiser des ressources de transmission.
