1. A user equipment (UE), comprising:
a transceiver configured to receive information about a channel state information (CSI) report; and
a processor, operably coupled to the transceiver, the processor configured to determine a set of vectors and a set of coefficients,
wherein the transceiver is further configured to transmit the CSI report including at least one indicator indicating the set of vectors and the set of coefficients, and
wherein:
the set of vectors is based on at least one of (i) a set of transmit (TX) vectors of length Nt and (ii) a set of receive (RX) vectors of length Nr, where Nt is based on a number PCSI-RS of non-zero power (NZP) CSI-reference signal (RS) antenna ports configured for the CSI report, and Nr is a number of antenna ports at the UE, and
a weighted summation of the set of vectors and the set of coefficients is associated with at least one of two dimensions of a downlink (DL) channel matrix measured based on the PCSI-RS NZP CSI-RS antenna ports.
