Abstract: front page image
(EN)The present invention discloses a method and device for generating codebook. The method comprises: receiving grouping information about multi-antenna of the base station; obtaining channel model of the channel which is between the mobile terminal and the base station; according to the grouping information and the channel model, determining optimum precoding matrix which corresponds to each antenna grouping so as to construct codebook for precoding. A method and device for selecting precoding matrix, a method, device and system for precoding are also disclosed in the present invention.
(FR)La présente invention porte sur un procédé et un dispositif de génération de livre de code. Le procédé comporte : la réception d'informations de groupage concernant les antennes multiples de la station de base, l'obtention d'un modèle de canal pour le canal entre le terminal mobile et la station de base et, conformément aux informations de groupage et au modèle de canal, la détermination d'une matrice optimale de codage préalable correspondant à chaque groupage d'antennes de façon à construire un livre de code pour codage préalable. La présente invention porte également sur un procédé et un dispositif de sélection de matrice de codage préalable, et sur un procédé, un dispositif et un système de codage préalable.
