Abstract[English]
Various aspects relate to channel state information (CSI) including a precoding matrix indicator (PMI). An apparatus (e.g., user equipment (UE)) generates a CSI report including a PMI for a precoding matrix and a channel quality indicator (CQI). The precoding matrix corresponds to layers with each layer associated with a spatial beam and a size of the set of layers determined by a rank indicator (RI). The precoding matrix is associated with a subset of CSI reference signal (RS)(CSI-RS) ports, and the PMI and the CQI are each associated with at least one of a wideband format or a subband format, with the subband format corresponding to reporting at least one of the PMI or the CQI for a subset of subbands of a bandwidth part associated with a CSI reporting setting. The apparatus transmits the CSI report including the RI, the PMI, and the CQI to a network entity.[French]
Divers aspects concernent des informations d'état de canal (CSI) comprenant un indicateur de matrice de précodage (PMI). Un appareil (par exemple, un équipement utilisateur (UE)) génère un rapport de CSI comprenant un PMI pour une matrice de précodage et un indicateur de qualité de canal (CQI). La matrice de précodage correspond à des couches, chaque couche étant associée à un faisceau spatial et à une taille de l'ensemble de couches déterminée par un indicateur de rang (RI). La matrice de précodage est associée à un sous-ensemble de ports de signal de référence de CSI (RS)(CSI-RS), et le PMI et le CQI sont chacun associés à un format à large bande et/ou à un format de sous-bande, le format de sous-bande correspondant au rapport du PMI et/ou du CQI pour un sous-ensemble de sous-bandes d'une partie de bande passante associée à un réglage de rapport de CSI. L'appareil transmet le rapport de CSI comprenant le RI, le PMI et le CQI à une entité de réseau.
