Abstract[English]
Various aspects of the present disclosure relate to channel state information (CSI) with indication of precoding matrix. An apparatus (e.g., user equipment (UE)) generates a CSI report including an indication of a precoding matrix, the precoding matrix corresponding to at least one codebook mode. The at least one codebook mode is based at least in part on a codebook type including a set of consecutive transformations including a first transformation including a reduction of dimensions of a plurality of CSI reference signal (RS) (CSI-RS) ports to a first transform domain, and a second transformation including a first linear transformation of the first transform domain to a second transform domain. The apparatus transmits the CSI report to a network entity.[French]
Divers aspects de la présente invention concernent des informations sur l'état du canal (CSI) avec indication de la matrice de précodage. Un dispositif (par exemple, un équipement utilisateur (UE)) génère un rapport CSI comprenant une indication d'une matrice de précodage, la matrice de précodage correspondant à au moins un mode de livre de codes. Le ou les modes de livre de codes sont basés au moins en partie sur un type de livre de codes comprenant un ensemble de transformations consécutives comprenant une première transformation comprenant une réduction des dimensions d'une pluralité de ports de signaux de référence CSI (CSI-RS) vers un premier domaine de transformation, et une deuxième transformation comprenant une première transformation linéaire du premier domaine de transformation vers un deuxième domaine de transformation. L'appareil transmet le rapport de CSI à une entité de réseau.
