Dear Huawei experts,
Could any one explain the relation between RS, Pa and Pb in Huawei LTE cell.
For fixed Pa, (0db) what is the impact when we do increase PS power on Symbols type A ?
Same question for symbols type B ?
The relation between RS Power and Cell max Power ?
Many Thanks

RS power will increase when you increase total power irrespective of Pa, Pb settings. Same for A type symbols and B type symbols.

I think this is not for Huawei but Nokia.
For Huawei, changing RS Power will increase total power accordingly. So if the new total power > Max RF Unit Power, cell is Down.
Please to confirm

Hi Fahmi,
The formulas of PA and PB are :
PSD =(pMax)-10*LOG10(PRBs_DL*12), where pMax is Maximum eNB transmit power per antenna port and PRBs is Number of available PRBs in DL.
RS Power = PSD - PA
PDSCH Type B =PSD +10*LOG10(PB
