PUSCH Throughput Conformance Test got throughput 0 with ue.RC = 'A4-3'

https://www.mathworks.com/help/lte/examples/pusch-throughput-conformance-test.html?s_tid=srchtitle

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,

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

Answer 2

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?

Answer 3

[Graham Freeland]

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.

So NFrame 100 to 500 shall be sufficient, to A4-3 EPA5 channel, right?
