Hi Pix, Thanks for reply;

Number of Attempts:
TBFEstAttUL = NUACATCL[1..3]
TBFEstAttDL = NUACATCL[4..6]

Number of estab_Failure:
TBFEstFailNoReactUL = SUCPDASA [1..4] – SULACCEL[1..4]
TBFEstFailNoReacDL = SUCPDASA [5..7] – SULACCEL[5..7]

Number of estab_Success:
TBFEstSuccUL = SULACCEL[1..4]
TBFEstSuccDL = SULACCEL[5..7]

UL_TBF_Succ_Rate=TBFEstSuccUL/TBFEstAttUL

Problem: high difference between SUCPDASA & SULACCEL which increase Fail due to no reaction from MS.
Where:
SUCPDASA:Number of successful PDCH assignments
(uplink/downlink) per cell
SULACCEL:Number of successful PDCH seizures (uplink/downlink)per cell

UL_Succ_Rate < 60% till 20% DL_Succ_Rate >=85%

No interferance is detected and Fail due to no reaction remains all the time.

Rx_Access_min = 6 -> -105 dB
(Alpha,Gam) = (0,0)
Init_MCS = MCS1

I changed T3168 from 1s to 2s, (waiting for remark after 2 or 3 days)

Thanks/ Best Regards
