Abstract
Apparatuses and methods for compression-based channel state information (CSI) reporting are provided. A method includes receiving a configuration about a CSI report, the configuration including information about N>1 groups of CSI reference signal (CSI-RS) ports and a codebook. The codebook includes a first component that includes P≥2 sets of basis vectors including a first set for spatial domain (SD) and a second set for frequency domain (FD) and a second component that includes coefficients associated with each basis vector combination (v, v, . . . , v), where vbelongs to a k-th set of basis vectors. The method further includes, based on the configuration, measuring the Ngroups of CSI-RS ports and determining the first component and the second component and transmitting the CSI report including one or multiple basis vector indicators indicating all or a portion of the first component and one or multiple coefficient indicators indicating all or a portion of the second component.
