WebWhat is CSI RS port? CSI-RS ports are the number of radiating elements (or group of antennas) of an active antenna unit. So there can be 4×4 MIMO with 8 CSI-RS ports with 16 CSI-RS ports or with 4 CSI-RS ports. Are not related with each other. Only conditions is that MIMO layers cannot be higher than CSI-RS ports. WebCSI reporting is the process by which a UE, for DL transmissions, advises a suitable number of transmission layers (rank), PMI, and CQI values to the gNB. The UE estimates these values by performing channel measurements on its configured CSI-RS resources. For more details, see the 5G NR Downlink CSI Reporting example. The gNB scheduler uses ...
