Abstract

L'invention concerne un procédé de configuration d'informations, comprenant les étapes consistant à : recevoir une signalisation de configuration envoyée par un noeud de réseau, et lorsque la signalisation de configuration est utilisée pour indiquer à un terminal d'envoyer au moins un élément d'informations de retour de requête de répétition automatique hybride (HARQ), chaque élément d'information de retour HARQ occupe une partie de symboles de domaine temporel dans la même sous-trame; configurer le ou les élément(s) d'information de retour HARQ sur la partie de symboles de domaine temporel dans la même sous-trame que celle occupée par chacun desdits éléments; et envoyer le ou les élément(s) d'information de retour HARQ au noeud de réseau.La solution technique décrite dans les modes de réalisation de la présente invention permet d'envoyer au moins un élément d'information de retour HARQ par l'intermédiaire d'une partie de symboles du domaine temporel dans la même sous-trame, ce qui permet à un UE ayant une capacité de réception sur liaison double et une capacité d'émission sur liaison simple d'envoyer simultanément et respectivement les informations de rétroaction HARQ à différents noeuds de réseau.FIG.
