Hi Experts.

I have one query related to Non-codebook based SRS.

In case of non-codebook based SRS, if we configure 4 SRS resources, will UE use 4 different antenna port corresponding to each SRS resource transmission?

Can anyone pls help to confirm?

yes, I think it is a must. Each SRS port with its own antenna. And gNodeB will also have 4 antenna. Other way it is noty possible MIMO 4x4.
