ian,
your avg windows look ok, i think you can tune them step by step if you want, but the effects are so important that I would only change one value at a time…
Regarding PC, try this
L_rxlev_UL_P=-90
U_rxlev_UL_P=-80
and then, 2nd step:
L_rxlev_UL_P=-92
U_rxlev_UL_P=-82
and then, 3rd step (for DL PC):
L_rxlev_DL_P=-82
U_rxlev_DL_P=-72
if things are looking better then let’s work on ‘upper’ thresholds:
U_rxlev_UL_P=-84
U_rxlev_DL_P=-74
(the effect is to decrease the “target” rxlev, which is the avg btw upper and lower thresholds, without getting to close to HO thresholds)
If still ok, then decrease symmetrically:
L_rxlev_UL_P=-94
U_rxlev_UL_P=-86
L_rxlev_DL_P=-84
U_rxlev_DL_P=-76
etc.
That would probably the lowest you can go though, but you can try to go further down 🙂
