Hi Pix and Blackhole,
Thank you for sharing experience.
We have here almost everywhere 4 TRX/sector, we had used 28 hopping frequencies. BCCH is very clean with 30 BCCH.
The bigger problem we encountered was some high HO Uplink Quality (25 to 30%) when DL_Quality is(around 15%).
We also had to Disable DTX_DL as this is a reported Bug with ALU.
We also activated PWCRL_DL.
Our parameters for HO and Pwrcrtl are pretty in the standard, so i dont really understand this sudden increase.
Thanks for your comments
