Hi LTE Experts,
I have one complicated scenario:
We have 2 cells with same eARFCN 300 and same PCI 100.
My source cell getting worse and target is good.
Need to understand whether my UE will send MR for A3/A5 or not in this case considering PCI is same.
If both source and target cells are of same freq and same PCI, then one normal neighbor addition is not possible.
UE can certainly measure neighbor and report neighor cells, but eNB cannot add them in neighbor relation table.
In that case, eNb can ask UE to meausre eCGI of nbr cell, after that HO can be possible.
But, I don’t have any evidence of this scenario, because in network such situation is called PCI confusion, and it it is resolved by SON.
eCGI is asked UE to read, but I think only in case PCI confusion where 2 neighbors same PCI, UE report A3-rsrp with PCI but enodeb do not know which target eNodeB.
So that, eNodeB will know which target eNodeB to send HO-request.
Here is PCI conflict, 2 cells same PCI, I think UE can not distinguish 2 cells and not report anything.
If serving and target cell have same PCI and eARFCN i.e. intra frequency then if serving level degraded is it possible for UE to send measurement report on basis of A5 considering target is better?
I think UE may send MR for event A5, but I doubt handover can be initiated.
Because in neighbor table it’s not posible to add NBR with same freq same PCI.
Yes same my thinking.
But I seen UE failed to send measurement report as well.
Need to check for sending measurement report what all info UE need to gather for target cell.
