Abstract

Les modes de réalisation de la présente invention décrivent un procédé et un appareil de transmission collaboratif de liaison montante. Les modes de réalisation de la présente invention concernent le domaine des communications, peuvent s'appliquer à la suppression du brouillage entre des équipements d'utilisateurs pendant la transmission de liaison montante et améliorent les performances des communications. Le système consiste plus précisément en ce que : un dispositif de gestion collaboratif obtient des informations d'Identité d'Utilisateur (ID) et de planification de ressources d'équipements d'utilisateurs dans un ensemble de cellules collaboratives par l'intermédiaire d'au moins une station de base ; l'ID de l'utilisateur d'au moins un premier équipement d'utilisateur de l'ensemble de cellules collaboratives est déterminé sur la base des informations de planification de ressources, et le premier équipement d'utilisateur est l'équipement d'utilisateur qui occupe les mêmes ressources de temps-fréquence que d'autres équipements d'utilisateurs de l'ensemble de cellules coopératives ; et, sur la base de l'ID de l'utilisateur dudit premier équipement d'utilisateur, un Indicateur de Matrice de Précodage (PMI, Pre-coding Matrix Indicator) est resélectionné dans un ensemble de livres de code prédéfini établi pour le premier équipement d'utilisateur, et le PMI est utilisé pour indiquer un indice de l'ensemble de livres de code afin de permettre au premier équipement d'utilisateur de précoder des données devant être transmises sur la base d'un livre de code indiqué par le PMI, cela permettant au premier équipement d'utilisateur de transmettre les données codées.
