In the nr-a3-rsrp-handover-algorithm.cc, how to determine the neighbor cells

[chang yi Liu]

I want to use the nr-a3-rsrp-handover-algorithm.cc for handover in my simulation environment, which has 10 gNBs, and 10 UEs are moving. However, I haven't specified in this file what the neighbor cells are for each gNB.

I am mimicking the nr-test-x2-handover-measures with the following code:  

nrHelper->SetHandoverAlgorithmType("ns3::NrA3RsrpHandoverAlgorithm");

nrHelper->SetHandoverAlgorithmAttribute("Hysteresis", DoubleValue(0.001));

nrHelper->SetHandoverAlgorithmAttribute("TimeToTrigger", TimeValue(MilliSeconds(0.001)));

the result is that all the UEs are connected to the initial  gNB , and there is no handover taking place.

So I want to know how the nr-a3-rsrp-handover-algorithm.cc performs handover.

Handover is not yet supported. Part of the required code is there already, but not in usable state.
