HARQEntity function does not get executed

When I try to execute HARQEntity function that is in one of MATLAB's examples, I get this message:

'HARQEntity' is used in the following examples:

DL-SCH and PDSCH Transmit and Receive Processing Chain

Model 5G NR Transport Channels with HARQ

NR PDSCH Throughput

NR PUSCH Throughput

6G Link-Level Simulation

NR NTN PDSCH Throughput

I tried to run NR PUSCH Throughput example and when it reaches HARQEntity Function the script give an undescriptive error.

Do you have a licence for MATLAB's 5G Toolbox, and is it properly installed ?

Use

license checkout matlab_5g_Toolbox

ans = 1

to see if the license is working properly.

Answer should be 1.

Which MATLAB version do you use ? If it's older than R2021b, the function is missing - it was released in R2021b.

I'm using MATLAB 2024b.

I do have a 5G toolbox license:

license checkout matlab_5g_Toolbox

ans =

1

But I'm not able to find HARQEntity.m

Here is the path where it was saved in an older MATLAB version:

Do the examples where the function is used work for you, e.g.

openExample('5g/Modeling5GNRTransportChannelsWithHARQExample')

?
