Best regards

You can get the following from NetSim.

Configuration data, can be got from the config file

• gNB parameters
• UE parameters (capabilities)
• Scenario set up (# of gNBs, # of UEs)
• Pathloss parameters … etc

Fine grained RAN measurements are available at a per UE level

• RF Propagation loss including its components: pathloss, shadow-fading and fast fading
• Received signal strength (RSS or RX Signal level), Layer wise RSS in case of MIMO
• Interference signal power
• Low PHY: (Digital) Beamforming gain in case of MIMO
• High PHY: Modulation and Coding (MCS), Channel Quality Information (CQI)
• Location and velocity measurements

I can see some of the measurement values in NetSim are shown in https://tetcos.com/5g.html. But I want to know if all information in NetSim is available periodically or is it event triggered?

And is it also possible to application-level data like DL throughput, UL throughput, etc?

There are some discussions on this at https://www.researchgate.net/post/Interfacing_AI_ML_models_with_NetSim

Thank you. One more question: Is it better to use supervised learning or Reinforcement learning for this kind of problem?

I would think that RL is the right approach. For example, you can have gNB(s) transmit power(s) as an “action” that changes the internal “state” of the network (desired signal and interference powers) and the “reward” can be the throughput or delay.

How does one go about recording the RAN measurement data in NetSim? What is the file format? And what tools are required for processing the data?

You can just "enable" logging of Radio measurements and/or Resource allocation.

The file can be opened and processed in Excel. See the screen shots in https://tetcos.com/5g.html

I appreciate all your answers. I was wondering if it is possible to use NetSim to generate synthetic data of (i) Radio resource allocation (for scheduler optimization) and (ii) Handovers (to tune handover margin, time to trigger etc)

Ashish Bagwari Yes, NetSim has a radio resource allocation log as well as a handover log.

Coming to RIC and ML, the two options are:

• Near RT-RIC, using x-Apps for individual UE and cell level ML
• Non RT-RIX, using r-Apps for cell level and network level ML

So your data collection should be based on what level you want to work. Since NetSim is a simulator both options can be explored.
