Hello,
I have a bit confusion.
Are pdsch transmission layer same as MIMO layers in 5G toolbox?
For example, in the code below: nlayers refer to 4 Tx antennas for MIMO transsmision? (where is the number of receiver's antennas in MIMO transmission)
modulation = '256QAM';
nlayers = 4;
ncellid = 42;
rnti = 6143;
data = randi([0 1],8000,1);
sym = nrPDSCH(data,modulation,nlayers,ncellid,rnti)

I think I have found the answer.
I ran the simulation by fixing code-rate and modulation and found the results that suggest my understanding was correct.
The rate for Num_layer = 1 is 1.486. When I increase the layer by 2,3,4 the increase in the rate is also by the same factor. See the image below.
