Abstract
Apparatuses, methods, and systems are disclosed for generating a CSI report. One apparatus includes a transceiver that receives a set of reference signals transmitted from a base station and a processor that transforms the set of reference signals to obtain per-layer vectors of amplitude and phase coefficients of a DFT-compressed codebook. Here, each amplitude coefficient vector and phase coefficient vector corresponding to a tap in at least one identified beam. The processor calculates a subset of the taps for the at least one identified beam and controls the transceiver to transmit CSI feedback including the calculated taps to the base station, where each tap is an inverse Fourier transform of rows of time-domain coefficient vectors and where the CSI feedback includes an indication of one or more elements of the vectors of amplitude coefficient vectors and phase coefficient vectors corresponding to the at least one identified beam.
