Abstract

La présente invention concerne un procédé de transmission d'informations, un dispositif de transmission d'informations, et un système de communication. Dans le dispositif de transmission d'Informations, une couche MAC détermine s'il faut exécuter ou ne pas exécuter une instruction ultérieure présentant une priorité plus élevée, ou une couche physique détermine s'il faut transmettre ou ne pas transmettre des données ou une demande de planification pour ledit service à priorité plus élevée. Ainsi, même si des ressources de liaison montante de divers services sont en conflit, le dispositif peut toujours satisfaire aux exigences de retard et/ou de fiabilité de services à priorité plus élevée tout en protégeant la transmission de services à priorité plus faible.
