Hi All,
All layers of same CW must be same in mcs, tbs?

2

Yes, correct.

I see in probe log LTE, if rank1 there is only sinr1, while rank2/3/4 there are sinr1 & sinr2.
So, SINR is measured for CW, right?

SINR is measured per physical antenna.
Before and after equalizer in the UE.

5

What are sinr1, sinr2?

6

There’s one SINR per each antenna.
Like in this picture (from Probe):

Here, why RANK1 only SINR, RANK2/3/4 have SINR1 & SINR2?

8

Could be sinr before and after equalizer.

So rank1 have not pre and post equalizer?

Rank1 has no precoding matrix and no equalizer.
