Dear Pix,
What a great info!Thanks alot, Now I know it. 🙂
Yes, I was mixing the value of Pmax and an example, I mean, If I set ALPHA=0 and GAMMA_TNX=10*2B, what it would become.
Sorry 🙂
May i repeat your explanation?, that would be :
The value of Pmax I stated before = GPRS_MS_TXPWR_MAX_CCH=43 dbm (ALU recommendation) with PBCCH.
The GPRS reselection applied is NC0 (which mean following the condition as same as voice service). I was wrong, PMax should be equal to MS_TXPWR_MAX_CCH = 33 dBm (ALU Recommendation). 🙂
By the way, attenuation 20 dB is due to UL PC GPRS from GAMMA_Tnx = 10*2dB 🙂 and Alpha=0.
Then you said about default ALU value of GAMMA_Tnx & ALPHA which means ENABLE UL PC GPRS, that would impact on how much power needed for MS to transmit UL Tbf. So, whenever we activate UL PC for GPRS , and also depends on a fluctuation of RXLev received in MS, it has a higher possibility to have a fail UL TBF establishment. It’s better to deactive UL_PC in GPRS (GAMM_TNx&ALPHA=0) because MS will transmit UL Establishment in a stable power (That’s 33 dBm).
I hope I’s right :).
well, thanks so much anyway.
If there were a facility in this forum to attach picture/statistic, that would be better 🙂 Hopefully, someday this forum can provide this facility. :):)
by the way, where are you working now? May I join you ? hihihihihi 🙂
Thanks & best regards,
Paul
