Abstract
Apparatuses and methods for channel state information (CSI) codebook parameters. A method performed by a user equipment (UE) includes receiving information about a channel state information (CSI) report, the information indicating N>1 CSI reference signal (CSI-RS) resources and a codebook. The codebook includes a spatial-domain (SD) basis component, a frequency-domain (FD) basis component, and a coefficient component. The SD basis component includes Lbasis vectors for each CSI-RS resource r=1, . . . , N. The FD basis component includes Mbasis vectors. The coefficient component includes coefficients associated with (SD, FD) basis vector pairs. The information includes codebook parameters. The method further includes, based on the information, measuring the N CSI-RS resources; determining, based on the codebook parameters, the SD basis component, the FD basis component, and the coefficient component; and transmitting the CSI report.
