In this example, changed the FRC from A3-2 to A4-3, then Run this script, got 0 throughput for all SNR values,not sure anything others needed to change or not?

UE Configuration

User Equipment (UE) settings are specified in a structure form.

ue.RC = 'A3-2'; % FRC number

BRs,

Scott

Should be good, run it and check the throughput curve trend.

Hi,

You'll have to move the SNR range of the simulation up since the code rate is now a lot higher, going from 1/3 (A3-2) to 3/4 (A4-3). You'll also need to increase the length of the simulation to get reliable results (the simulation example code is set to a short run to make it practical in the first instance).

Thanks for the answer, do we have recommended range of simulation length for different code rate?

The simulation length will generally depend on the channel doppler. A4-3 is used in reference tests using EPA5 or EVA70 channels. The standard specifes very long simulations for RAN4 tests but 1000-5000 subframes may be sufficient for reasonable convergence.
