Abstract

La présente invention concerne un procédé et un dispositif de communication et permet d'améliorer la qualité de communication d'un terminal et de réduire les retards de transmission de liaison descendante. Le procédé comprend : l'envoi par un premier nœud d'informations de configuration d'une première ressource temps-fréquence, la première ressource temps-fréquence constituant une ressource de premières informations de liaison montante reçues en provenance d'un troisième nœud par un deuxième nœud, et le deuxième nœud constituant un relais du premier nœud et du troisième nœud ; les premières informations de liaison montante constituent des informations de rétroaction de liaison montante de données de liaison descendante, et les données de liaison descendante constituent des données de liaison descendante envoyées au troisième nœud par le premier nœud, ou les premières informations de liaison montante constituent des données de liaison montante du troisième nœud programmées par le premier nœud ; et la réception par le premier nœud des premières informations de liaison montante, en provenance du deuxième nœud, sur une deuxième ressource temps-fréquence. La présente invention se rapporte au domaine technique des communications.
