Abstract

La présente divulgation concerne un procédé et un appareil de rétroaction de demande de répétition automatique hybride (HARQ), et un support de stockage. Le procédé consiste à : recevoir des informations de commande de liaison descendante (DCI), les DCI comprenant des informations de commande latérale ; et en fonction des DCI, déterminer d'effectuer une rétroaction HARQ sur un dispositif de réseau, la rétroaction HARQ représentant la réalisation d'une rétroaction HARQ sur les DCI. Ordonner, au moyen des DCI, l'exécution d'une rétroaction HARQ sur les DCI comprenant les informations de commande latérale permet à différentes signalisations de pouvoir prendre en charge différents modes de rétroaction, ce qui permet d'assurer la réception correcte de la signalisation correspondante et d'améliorer la robustesse des systèmes de communication.
