Abstract

La présente invention concerne un procédé et un dispositif de fin précoce de transmission, le procédé consistant à : recevoir un premier bloc de données qui est téléversé de manière répétée par un terminal dans un système de communication du type machine (MTC) ; avant que le nombre total de fois que le terminal téléverse de manière répétée le premier bloc de données n'atteigne un premier nombre cible de fois, déterminer si le premier bloc de données est démodulé avec succès, le premier nombre cible de fois étant un nombre maximal de fois pour téléverser de manière répétée chaque bloc de données, comme cela a été configuré par une station de base pour le terminal ; et s'il est déterminé que le premier bloc de données est démodulé avec succès avant que le nombre total de fois que le terminal téléverse de manière répétée le premier bloc de données n'atteigne le premier nombre cible de fois, transmettre des informations de commande de liaison descendante (DCI) cibles au terminal. La présente invention peut atteindre le but de terminer une transmission en avance lorsqu'un terminal téléverse de manière répétée un bloc de données, ce qui est avantageux pour économiser des ressources d'un terminal dans un système MTC.
