Nokia - A3 Event for Inter-Freq HO

Hello Nokia LTE experts!
I have a problem with the handover between frequencies in a CBRS network.
The A3 event never happens for Inter-Freq HO (only for Intra-Freq cells). I have tried different sets of Offsets, Hysteresis, etc but nothing happens.
LNREL and LNHOIF MOs were created.
A5 is working, but A3 is preferable and easier to implement.
I appreciate any ideas.
