(EN) METHOD AND APPARATUS FOR HIGH RESOLUTION CSI CODEBOOK
(FR) PROCÉDÉ ET APPAREIL POUR LIVRE DE CODES DE CSI À HAUTE RÉSOLUTION
Abstract
(EN) Apparatuses and methods for high resolution CSI codebook is provided. The method includes receiving configuration information on a channel state information (CSI) report, the configuration information including a parameter d≥1, where d is a number of principal components; determining left principal component vectors; determining right principal component vectors; determining principal singular values; and transmitting the CSI report including a precoding matrix indicator (PMI), the PMI indicating the left principal component vectors, the right principal component vectors, and the principal singular values, wherein at least one of the left principal component vectors, the right principal component vectors, or the principal singular values is selected from adaptive codebooks.
(FR) L'invention concerne des appareils et des procédés pour un livre de codes de CSI à haute résolution. Le procédé consiste à recevoir des informations de configuration sur un rapport d'informations d'état de canal (CSI), les informations de configuration comprenant un paramètre d ≥ 1, d étant un nombre de composantes principales ; à déterminer des vecteurs de composantes principales gauches ; à déterminer des vecteurs de composantes principales droites ; à déterminer des valeurs singulières principales ; et à transmettre le rapport de CSI comprenant un indicateur de matrice de précodage (PMI), le PMI indiquant les vecteurs de composantes principales gauches, les vecteurs de composantes principales droites et les valeurs singulières principales, au moins un élément parmi les vecteurs de composantes principales gauches, les vecteurs de composantes principales droites ou les valeurs singulières principales étant choisi parmi des livres de codes adaptatifs.
