Hello Adele,

you are not providing enough enough, anyway, you can check for the value of the RTWP, if it is high, that can cause these failures.

Hello,
Regarding AC rejection , it could be due to couple of limiting reasons:
1) number of HSDPA users which could be subject of license limitation
2) It could be due to high CE utilization if you haven't reserved enough CE for ADCH
So you need to check them first

cheers

Hi,

Do you mean Setup Fail HSDSCH due to UE? What exact AC counter is triggered? This can be UL or DL related. Also, what SW version of NSN are you? Without this information, its difficult to analyse...

Try to check the licensed loaded...
most of the time missing license after upgrade cause this degradation.

if all config and license is correct..
try recommissioning the site..
Just reload all config..

let me know if it works...
