Parameters to highway with LTE

[huawrx]

Hi guys,

We have high degradation HO between 2 cosites cell with LTE, do you know which parameters can we modify to improve these HO? margin in quality, signail or something like that?

thanks guys¡

don't shy please together we can find optimal parameters, i only know this parameter A3offsert kpi to improve is HOSR per cell relation, from neighbor cell towards the loaded cells, To speed HO in case of fading.

In other part os this forum, the user jayk answer me:
Once you know the reason of HO failures then you can adjust the boundaries of HO with these parameters

IntraFreqHoA3Hyst
IntraFreqHoA3Offset
IntraFreqHoA3TimeToTrig

CellIndividualOffset

InterFreqHoA1A2Hyst
InterFreqHoA1A2TimeToTrig
InterFreqHoA1ThdRsrp
InterFreqHoA1ThdRsrq
InterFreqHoA2ThdRsrp
InterFreqHoA2ThdRsrq
InterFreqHoA4Hyst
InterFreqHoA4ThdRsrp
InterFreqHoA4ThdRsrq
InterFreqHoA4TimeToTrig

Please thanks to him.

Hi,
i don't know these cells is inter or intra，you could modify CIO,A1，A2，A4,or inter A3,
check cell to cell KPI,To confirm there are other problems.
I'm sorry, my English is not good

Hi shihaonan, between cells intra, i try with CIO between neighbors however not improve only reduces the HO, but the HO fails reduce at the same time that the attempts, currently we have -114A1/-116a2, do you have more ideas about the thresholds in A1/A2 A4.

thanks bro

[shihaonan]

if the cells intra,HO event is A3,not need adjust A1/A2 A4,check target cell Whether there is alamf,congestion,interference,external data,the between cells‘s coverage.

if there is inter around,you can try to adjust -98A1/-102A2,-98A4.

I have a tool for view signaling.

@zins
Could you share this tool
