In 5G each CSI-RS resource indicator (CRI) is 1 beam, is it right?
Basically cri is configured as part of report quantity.
So it depends on how many ssb beam configured in your system.
Let’s say with 2 ssb beams with 4x2 we have single cri.
You need to look inside RRC Connection Reconfig and search for nzp-csi-rs.
There you will see how many ports are configured.
For e.g., if 1 cri has 8 ports, how many beams?
