Channel-State Information Reference Signal (CSI-RS) is used for DL CSI downlink acquisition. It is also used for Reference Signal Received Power (RSRP) measurements used during mobility and beam management It is also used for frequency and time tracking, demodulation and UL reciprocity based pre-coding.
CSI-RS is configured specific to UE, however multiple users can share the same resource.
The 5G NR standard allows a high level of flexibility in CSI-RS configurations. A CSI-RS resource may start at any OFDM symbol of the slot and it usually occupies 1, 2, or 4 OFDM symbols depending upon the configured number of ports. It can be periodic, semi-persistent, or aperiodic (this is due to DCI triggering). For time and frequency tracking, CSI-RS can either be periodic or aperiodic. It is transmitted in bursts of two or four symbols which are spread across one or two slots.
This topic describes the following CSI-RS properties:
Row Index of CSI-RS Location table
PRB Allocation for Density = 0.
Resource Elements used for PDSCH
Adds a CSI-RS to the transmission. Supports up to 32 CSI-RS channels.

Time domain: Use Allocated Slots to set slot allocation, and the symbol allocation is determined by the CORESET selection.
Frequency domain: Select BWP first, and then CORESET index in the BWP. After selecting CORESET index, use CCE offset and CCE number to set the frequency location of DCI.
Sets the slot indexes allocated for the selected CSI-RS. Allocated Slots are entered as an array of slot indexes allocated for the CSI-RS. 5G NR slot format combination structures are defined in 5G NR 3GPP TS 38.200 series standards.
There are three ways to configure:
Sets the allocated slot index for the channel. Allocated Slots are entered as an array of slot indexes allocated for the PUCCH. There are three ways to configure:
To configure by individual index, use ',' as the delimiter, e.g. 0,1,2,3.
To configure by a range of index, use ':' to indicate the start index and the last index, e.g. 3:10 means 3,4,5,6,7,8,9,10.
To configure by a certain step, use two ':' to indicate the start index, the step and the last index, e.g. 0:4:12 means 0, 4, 8, 12.
These three configuration methods can be used in combination, by using ',' as the delimiter, e.g. 0,1,4:7,8:2:19 means index 0,1,4,5,6,7,8,10,12,14,16,18.
If the slot allocation is different for different frame, use '{ }' and '|' to specify the frame index, for example, {0|0,1,2},{1|3,4,5} means slot 0,1,2 for frame 0, and slot 3,4,5 for frame 1. Ensure the Number of Radio Frames under Waveform Setup node is large enough.
