L.Traffic.UL.SCH.QPSK.TB counter has increased lot and impacted UL Throughput in one cell only

Only solution is coverage reduction, i.e. overlapping reduction to minimise noise.

Thanks, will go through this option.

Please, plot on same duration (21/04 - 16/08) as other graph.

See the increase:

I think this increase is in same duration as your degradation. There is gradual increase traffic usage until July/Aug and after that it more or less stabilised. You need to find why this traffic increased - is it genuinely more customers or new package introduced and existing user downloading more, etc.

I think you cells grabs more Traffic from weaker RF.

Hello, was this issue resolved?
If not, I can suggest improvement trial only if it’s Huawei.
