Abstract
Some embodiments of this disclosure include apparatuses and methods for reporting channel state information (CSI) for multiple spatial layers. The apparatuses and methods can include at least: determining, by a user equipment (UE), a precoding matrix indicator (PMI) for a set of precoding matrixes, wherein the PMI is determined based on a combination of digital Fourier transformation (DFT) spatial domain (SD) vectors, or based on DFT-based frequency domain (FD) compression; and transmitting, by the UE, the PMI to a next-generation NodeB (gNB).
