1. A method for a user equipment (UE) to perform a channel state information (CSI) measurement based on measuring a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH) transmission, the method comprising:
enabling, based on higher layer signaling received from a base station, a PDSCH resource mapping for frequency hopping corresponding to a number of hops;
determining, at the UE, the DMRS for the PDSCH transmission with the frequency hopping for the CSI measurement;
measuring the DMRS for the PDSCH transmissions;
determining the CSI measurement based on the measured DMRS for the PDSCH transmission; and
reporting the CSI measurement to the base station.
