Abstract

La présente invention concerne un procédé et un dispositif de transmission de signalisation, destinés à résoudre un problème dans l'état antérieur de la technique selon lequel un champ de validation dans une signalisation d'activation ou une signalisation de désactivation ne peut pas être transmis avec précision entre une station de base et une unité d'équipement d'utilisateur dans un système de NR 5G. Le procédé comporte les étapes suivantes: une station de base génère une signalisation d'activation ou une signalisation de désactivation de transmission de données, le champ de numéro de processus de HARQ et/ou le champ de version de redondance dans un PDCCH étant configuré(s) comme un champ de validation dans la signalisation d'activation ou la signalisation de désactivation; et le PDCCH est utilisé pour transporter la signalisation d'activation ou la signalisation de désactivation de transmission de données générée afin de l'envoyer à une unité d'équipement d'utilisateur. Une station de base génère une signalisation d'activation ou une signalisation de désactivation, de telle façon qu'un champ de validation dans la signalisation d'activation ou la signalisation de désactivation soit transmis entre la station de base et l'équipement d'utilisateur dans un système de NR 5G.
