Is it possible to measure packet level delay (delay faced by individual packets) in the 5G toolbox? If so, how?
I want to implement an uplink scenario where the UEs upload traffic to the gNB (following the existing standards in 5G). I need to measure the delay faced by individual packets. Any suggestions?

Yes, I am actually facing the same problem. It would be nice to get some informantion on how we can track it.

Hi. No, I have not. It seemed to me MATLAB 5G toolbox is only considering like a byte stream rather than packets. I also needed more flexibility from upper layers, which were not there on MATLAB. So, I switched to Simu5G on OMNET++. Not sure, if they have built anything new after that.

Hello Laha,
I understand that you are trying to measure the delay faced by individual packets in a 5G uplink scenario using the 5G Toolbox.
As of now, there is no feature that allows user to directly achieve this. However, there are indirect ways in which you can accomplish the same. Here are some suggestions for measuring packet-level delay:
  • Use the logging features at the desired layer, provided by the 5G Toolbox, to capture the timestamps of packet transmission and reception.
  • Calculate the delay for each packet by subtracting the transmission timestamp from the reception timestamp.
  • Store the delay values in an array or a log file for further analysis.
Note that the specific implementation details may vary depending on your simulation setup and requirements.
Please refer to the answer provided in the MATLAB Answer for a similar query.

I hope this helps you to have an example where you could compute the delay incurred by individual packets by following the steps mentioned above and in the answer of the related question.
