All layers of same CW must be same in mcs, tbs?
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.
What are sinr1, sinr2?
There’s one SINR per each antenna.
Like in this picture (from Probe):
Here, why RANK1 only SINR, RANK2/3/4 have SINR1 & SINR2?
Could be sinr before and after equalizer.
So rank1 have not pre and post equalizer?
Rank1 has no precoding matrix and no equalizer.
