Abstract

L'invention concerne : une technique de communication permettant de fusionner, avec une technologie IdO, un système de communication 5G destiné à prendre en charge un débit de transmission de données supérieur à celui d'un système 4G ; ainsi qu'un système correspondant. La présente invention concerne un procédé et un système de gestion de ressources (102) permettant d'améliorer le décodage d'informations de canal de liaison montante (UCI) dans un réseau de communication. Le procédé consiste à configurer au moins une ressource de demande de répétition automatique hybride (HARQ) parmi une pluralité de ressources HARQ pour un équipement utilisateur (UE)) (103), identifier une performance de décodage de chacune des ressources HARQ configurées et sélectionner une ressource HARQ parmi les ressources HARQ configurées pour un décodage d'UCI sur la base d'un paramètre prédéfini.
