hi manu (no sir, please !!)
Thanks for your answer, it’s detailed and precise, that’s rare enough on this forum to be highlighted !
Some averaging windows are very short (“2”), but not for the quality HO (“4”). Therefore I would not modify them in regards to your current issue.
However, later, you could try to increase the A PBGT HO, and perhaps the A LEV HO.
What are the values for L_RXQUAL_DL_H ? (there is one for AMR, one for legacy codec, etc..) and the FH OFFSET ?
Waiting for your feedback on the Path balance and Idle band Intf.
