How to simulate manual UE handovers during a system level 5G simulation?

I am currently working on a 5G system level simulation in MATLAB. Since I am new to matlab I am following this example.

I am looking for guidance on how to simulate the handover process for UEs while the simulation is actively running. Is there a function that takes the UE object and the target gNB then perfroms handover?

Any insights or sample code snippets on how to achieve this would be greatly appreciated. Thank you in advance for your help. I would appreciate if the resources are following the same structure as the linked example as I am not expert in matlab.

Thanks in advance.

Hi Zeyad,

As per my understanding you want to simulate the handover process for UEs while the simulation is actively running. The possible workaround for the same could be:

Following the MathWorks Documentation till the latest release of R2024a, it suggests that the "handover" functionality is currently unavailable in the "5G Toolbox", therefore no direct function is available that takes the UE object and the target gNB as input and perform the handover directly.

An alternate way to achieve the 5G Handover is using the "Reinforcement Learning". Please refer to the MATLAB Answer below which has a workaround for your question.

Hope this helps!
