According to the 5G NR Downlink CSI Reporting, CSI-RS is the channel/signal that is used by the UE to measure and obtain the CQI. CSI-RS stands for Channel State Information Reference Signal, which is a downlink reference signal transmitted by the gNodeB to enable the UE to estimate the channel quality and feedback the CQI to the gNodeB. The CQI is an indicator of how good or bad the channel quality is, and it can be used by the gNodeB to adjust the modulation and coding scheme for data transmission.
