Abstract

L'invention concerne un procédé et un dispositif pour transmettre et recevoir des informations de rétroaction de données de liaison descendante. Le procédé et le dispositif sont utilisés pour, lorsqu'une transmission de données dans un intervalle de temps court est utilisée du côté réseau, amener un équipement utilisateur (UE) à fournir une rétroaction de données reçues dès que possible, ce qui permet de raccourcir un temps d'aller-retour (RTT), de réduire un retard temporel du côté utilisateur, et d'améliorer les performances du système. Un mode de réalisation de la présente invention concerne un procédé pour transmettre des informations de rétroaction de données de liaison descendante, ledit procédé comprenant les étapes suivantes : un équipement utilisateur (UE) reçoit des données de liaison descendante transmises par le réseau au moyen d'un intervalle de temps comme unité ; l'UE transmet au côté réseau des informations de rétroaction des données de liaison descendante à l'aide d'une sous-trame ou de l'intervalle de temps comme unité, ledit intervalle de temps étant une unité de temps ayant une longueur inférieure à 1 milliseconde.
