Abstract

L'invention concerne un procédé, une station de base et un équipement utilisateur de transmission/réception de messages de requêtes automatiques de répétition hybride (HARQ). Plus particulièrement, le procédé de transmission de messages de HARQ comprend les étapes suivantes : convertir un schéma de configuration de liaison montante-liaison descendante de duplexage par répartition dans le temps (TDD) d'un premier schéma en un deuxième schéma; déterminer qu'un message de HARQ correspondant à des données dans une sous-trame de liaison montante qui est basée sur un premier schéma doit être transmis dans une sous-trame qui est basée sur un deuxième schéma ; et sélectionner, sur la base de la temporisation de HARQ déterminée, une sous-trame à utiliser pour la transmission du message HARQ de sorte que la sous-trame sélectionnée est conforme au deuxième schéma, la temporisation de HARQ déterminée correspondant au schéma de configuration de liaison montante-liaison descendante TDD et l'ensemble de sous-trames de liaison descendante désignée dans le schéma de configuration de liaison montante-liaison descendante TDD constituant un sous-ensemble de l'ensemble de sous-trames de liaison descendante indiqués dans le premier schéma, et l'ensemble de sous-trames de liaison descendante indiqués dans le deuxième schéma.
