Abstract

La présente invention concerne un procédé d'accusé de réception de requête de répétition automatique hybride (HARQ-ACK), une signalisation et un dispositif. Ledit procédé comprend les étapes suivantes consistant à : acquérir des informations de configuration pour indiquer respectivement les types de N livres de codes HARQ-ACK, les N livres de codes HARQ-ACK étant associés à une unité de temps ; et déterminer des informations concernant le livre de codes selon le type du i-ème livre de codes HARQ-ACK. En outre, les N livres de codes HARQ-ACK sont associés à M sous-unités de temps ; et les informations de configuration sont en outre utilisées pour indiquer les types des livres de codes HARQ-ACK correspondant aux M sous-unités de temps. La signalisation de configuration contient les informations de configuration ; et le dispositif est utilisé pour acquérir les informations de configuration, déterminer les types de N livres de codes HARQ-ACK, déterminer des informations concernant le i-ème livre de codes HARQ-ACK et envoyer ces dernières, ou le dispositif est utilisé pour envoyer les informations de configuration et recevoir les informations concernant le livre de codes HARQ-ACK. La présente invention résout le problème selon lequel la fiabilité, le retard temporel et l'efficacité de la rétroaction HARQ-ACK ne satisfont pas aux exigences lorsqu'un dispositif terminal prend simultanément en charge des types de service ayant différentes exigences de fiabilité et/ou de retard temporel.
