Abstract
Systems and methods provide a channel state information (CSI) measurement based on measuring a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH) transmission. A user equipment (UE) triggers measuring of a CSI reference signal (CSI-RS) from a base station. The UE triggers measuring of a DMRS for a PDSCH transmission from the base station. The UE generates a CSI report to report the CSI measurement, based on both the CSI-RS and the DMRS for the PDSCH transmission. The UE may then send the CSI report to report the CSI measurement to the base station.
