Hi,

How the CSI-RS and SSB beams are related in NR?

If both the beams are not related, and UE gives CSI-RS beam feedback then that beam won’t be the best beam for synchronization.

I think in the CSI config, there an IE to relate csi and ssb beams.
So that you can explicitly relate the two, so if one changes, the other follows.

Read this complementary info, this one is very good to understand the concept:

Csi rs beams are more narrow beams.
It’s like 1 ssb beam consist of 4 refined beams.
For synchronisation ssb beam used.
