Abstract

La présente invention concerne un procédé et un dispositif de retour d'informations d'état dans un mode à double liaison. Le procédé consiste à : déterminer, par un équipement d'utilisateur, qu'une transmission d'un rapport d'état de RLC à une station de base auxiliaire est nécessaire ; et, lorsqu'une condition de transmission de rapport d'état de RLC prédéfinie est satisfaite, transmettre, par l'équipement d'utilisateur, le rapport d'état de RLC à la station de base auxiliaire et transmettre un rapport d'état de PDCP à une station de base principale. Ceci permet à une couche de PDCP de la station de base principale d'avoir connaissance à temps d'un état de réception de l'UE par rapport à des paquets de données de PDCP, permettant ainsi de déplacer à temps un créneau de transmission de la station de base principale afin d'augmenter la vitesse de transmission des données.
