Yes you were right,changing threshold is hiding problem but though there is no increase degradation in RxQual.
Secondaly, We are Using AMR FR & AMR HR, Power Control is also enabled in both UL & DL & Frequency Plan is based on Optimised plan from a tool Output based on sig strenth & measuring BCCH’s.
This Bad DL Quality scenario is across all the network. e have done lot of Physical Optimization & overshooting but still DL Rx Qual is below 95%(0to5/0to7)samples.
Can you suggest what need to be checked further. Also i suspect following, please suggest :
1.Disabling AMR(can there be AMR issue)??
2.Can DTM effect in RxQual DL??
3.Can there be a difference in RxQual Sub & Full…do u have any instances where after Disabling DTX, We can see improved RxQuality??
