Hi Experts,
How do you deal with pusch interference?
And Uppts interference?
I have issue in 1st carrier of TDD only. (It ll also appear in a neighbouring sector)
I have tried interference suppression, pusch irc switch , randomisation via ENB based,
It has had no impact on interference.
Also it may be due to GPS toggling alarm, it will appear in one site and Most of the Neighboring area will be impacted.
Please check GPS alarms and availability.
You didn’t get my suggestion.
PRACH, due to large delays on cells, is interfering the PUSCH so you will get PUSCH degradation not PRACH degradation.
What prach config index has your cell and what zerocorrelationzoneconfig?
How many intra-freq neighbours have your cell?
In your chart I see values like -120 dBm max for PUSCH.
It is not too bad, I think.
Zero correlation 11 corresponds to a maximum cell range of 12 km.
So if you have users served from 15 km for example than there will PUSCH interference by PRACH.
This is why I asked how many neighbours has your cell to understand how large is the footprint: so you have 30 neighbours, 60 neighbours, 100 neighbours?
It’s the last site.
Not highly populated area. Down tilt is at 2 currently. It was zero. Height 45m.
But one of the neighbours too has similar problem.
I have 2 tdd carriers in one sector.
Issue only showing up in 1st carrier/ 2nd carrier is ok.
In both cases where I have this issue.
One sector of the neighbour in 1st carrier only for have the same trend shared earlier
2 degree is not enough, till shooting to the stars. Make it 3 degrees and have a look again
45m height and 2 degree only tilt you get no coverage close to site like this.
Make it 3 degrees and all KPIs will improve and you will get rid of the area with problem (far from site) where anyway UE has not enough power to serve it.
