Csi-rs vs srs based beamforming
WebThis method is known as reciprocity-based beamforming. This example implements downlink MU-MIMO by calculating a channel estimate for multiple users based on their SRS transmissions. Assuming reciprocity, … WebCSI-RS is a downlink-specific (DL) reference signal. The NR standard defines zero-power (ZP) and non-zero-power (NZP) CSI-RSs. The user equipment (UE) processes utilize …
