All other KPIs are fine but bad UL Throughput

Hi friends.

All other KPIs are fine, except UL throughput, which is degrading.

What may be the reason for it?

What about RSSI and SINR?

Sudden traffic dip on same time, some thing wrong on same time.

RSSI is fine:

What about electrical tilts?

Might be user profile changed?

Is this behavior on 1 site only?

No change in tilts, no change in TA Samples.

Yes.

PRB utilization?

UL Throughput and UL Data volume went down…

You mentioned that tilt was not changed, but I would set it to minimum just to check if etilt is working properly.

It could also be a big finger error so you can check before and after if any parameter was changed.

Checked, etilt working properly but no improvement in UL Throughput.

No parameter, no software changes before and after degradation.
