1. A method for a user equipment (UE) to report a channel state information (CSI) measurement, the method comprising:
triggering measuring of a CSI reference signal (CSI-RS) from a base station;
triggering measuring of a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH) transmission from the base station;
generating a CSI report to report the CSI measurement based on both the CSI-RS and the DMRS for the PDSCH transmission; and
sending the CSI report to report the CSI measurement to the base station.
