Abstract[English]
Various aspects of the present disclosure relate to codebook configuration for channel state information (CSI). A user equipment (UE) receives CSI configuration including a codebook configuration for precoder matrix indicator (PMI) reporting, where the codebook configuration includes a codebook type and the codebook type includes a set of parameters identifying at least one of a first transformation of a spatial domain, a second transformation of a frequency domain, or a third transformation of a time domain. The UE measures CSI based at least in part on one or more received reference signals (RSs), and transmits a CSI report including a set of CSI parameters, where the set of CSI parameters are based at least in part on the measured CSI and the CSI configuration, and the set of CSI parameters indicate at least one of the first transformation, the second transformation, or the third transformation.[French]
Selon divers aspects, la présente divulgation concerne une configuration de livre de codes pour informations d'état de canal (CSI). Un équipement utilisateur (UE) reçoit une configuration CSI comprenant une configuration de livre de codes pour un rapport d'indicateur de matrice de précodeur (PMI), la configuration de livre de codes comprenant un type de livre de codes et le type de livre de codes comprenant un ensemble de paramètres identifiant au moins une transformation parmi une première transformation d'un domaine spatial, une deuxième transformation d'un domaine fréquentiel ou une troisième transformation d'un domaine temporel. L'UE mesure les CSI sur la base, au moins en partie, d'un ou plusieurs signaux de référence (RS) reçus, et transmet un rapport CSI comprenant un ensemble de paramètres CSI, l'ensemble de paramètres CSI étant basé au moins en partie sur les CSI mesurées et la configuration CSI, et l'ensemble de paramètres CSI indiquant la première transformation et/ou la deuxième transformation et/ou la troisième transformation.
