Reply To: Increase in Interferance HOs with DTX


Hello PIX, Lily and Sergio,

just want to share our results regarding this Parameter W_Qual_HO,

We tried it for few cells with settings,


and result was increase in Interefrence and Quality HOs.

Explanation given to us by vendor was that averaging window becomes variable and is more reactive to transitional degradations in DL RX Quality resulting in increased Quality HOs.

I have to say that this weightage concept was really strange as we were thinking that size of averaging window will remain same and just DTX = 0 measuremnts will get twice the weightage of DTX = 1 measurements and averaging will be over 6 measurements regardless of how many were DTX or Non DTX and denominator of averaging could be modified accordingly.

Needless to say that we have reverted back to orignal settings and we are still having very high DL Interfernce HOs(around 5%) for all of our BSCs where AMR and DTX for AMR HR and FR is enabled.
