Cells with signal fluctuating solved after changing PCI

Hello Experts.

There are signal fluctuating happening in some 700 NR SA cells.

After change PCI it is getting resolved.

Any reason behind it?

When you change PCI, cell is restarted.

Maybe restart fixed a lot of other things…

There is high signal fluctuating in old PCI as we change it is sync up.

But no alarms, nothing.

And with new PCI proper signal and latching.

BB Restart does not help either.

If you work on open RAN or SA there are a lot of issues without alarm.

Or simply you have mod3 PCI interference.

But mod 3 has interference issue not signal fluctuating, I believe. In RSRP.

SINR issue should come.
