Does R17 UE in mu-mimo can get 4 layers DL?

I am going to test MU-MIMO in commercial network with 16 DL layers, rank4 4 users, or 8 users with rank2.

Users must be separated geographically, not decided yet if I should use 2 beams at sector, or 6 beams.

Also thinking what should be the distance btw users, there should be a calculation according to the beamwidth.
