Beam management and NR csi-rs reference signal Spec Number

Hi Specification Experts,

Which specs number need to refer for beam management and NR csi-rs reference signal?

There are multiple.
You can refer - 38.331, 38.212 and 38.214.

Thanks. I’m looking all these, but in one place not getting all details in Specs.
So thinking maybe I’m missing right approach? :frowning:
