Title (EN) METHOD AND PRECODER INFORMATION FEEDBACK IN MULTI-ANTENNA WIRELESS COMMUNICATION SYSTEMS
(FR) PROCÉDÉ ET RÉTROACTION D'INFORMATIONS PAR PRÉ-CODEUR DANS DES SYSTÈMES DE COMMUNICATION SANS FIL À ANTENNES MULTIPLES
Abstract: front page image
(EN)A method for two component feedback in wireless communication systems is disclosed, with a wireless communication device sending a first representation of a first matrix chosen from a first codebook, wherein the first matrix has at least two columns, the wireless communication device sending a second representation of a second matrix chosen from a second codebook, and the base station obtaining a precoder from the first representation and the second representation.
(FR)L'invention concerne un procédé destiné à une rétroaction à deux composantes dans des systèmes de communication sans fil, un dispositif de communication sans fil envoyant une première représentation d'une première matrice choisie à partir d'un premier livre de codes, la première matrice comportant au moins deux colonnes, le dispositif de communication sans fil envoyant une seconde représentation d'une seconde matrice choisie à partir d'un second livre de codes, et la station de base récupérant un pré-codeur de la première représentation et de la seconde représentation.
