Abstract

La présente invention concerne, dans des modes de réalisation, un procédé et un dispositif d'attribution d'une ressource de transmission de données. Le procédé comprend les étapes consistant à : acquérir un volume de données de transmission total d'au moins un canal logique attribué à des données à transmettre à un moment de transmission actuel, puis acquérir un premier volume de données de chaque canal logique dans l'au moins un canal logique au moment de transmission actuel, le premier volume de données étant égal à au moins une partie d'un volume de données de l'échec de transmission de chaque canal logique à un premier moment de transmission ; et attribuer le volume de données de transmission total à l'au moins un canal logique, sur la base de la priorité de chaque canal logique, de manière à garantir le premier volume de données et le volume de données de transmission prioritaire actuel de chaque canal logique puis à garantir le reste du volume des données à transmettre, à l'exception du premier volume de données et du volume de données de transmission prioritaire actuel dans chaque canal logique, afin de multiplexer le volume de données de chaque canal logique au moment de transmission actuel. Les modes de réalisation de la présente invention réduisent le retard de transmission d'un canal logique à priorité moindre.
