MIMO Config Interpretation

Ok. I think my question was confusing, I’ll rephrase it below:
This is for 4G.
In RRC reconfig I have ant port count as 8 in csi-rs config.
For the same timestamp I have PDSCH MIMO config 2x4 ie 2 antenna ports

I’m trying to understand this:
Should I report 8 x4 or 2x4

Note: it is for a live NW, not a simulator.
