Helpfull topic about papb
With Pb=0 it meant you are no more power boosting.
You kept RS power same i think to keep the coverage intact as before.

Remember these tables you can see by setting PB=0 there is no increment on CRS RE but PDSCH power increase to 5/4 resulting in improvement in throughput.
Cheers!!!

in our network, for example, we have b3, 20 W power, and config is RS power 152, Pa -3 Pb 1. If try to change Pa and Pb to 0;0, it makes error RRU power limit exceed, so need to use PaPb calculator from FMA. But if try to make 0;0, i also shoud reduce RS power from 152 to 122, so i lost coverage
Band 3 FDD 20 mhz
here is the link: https://5g-tools.com/4g-lte-rs-re-power-calculator/
here you can calculate the ReferenceSignalPwr value. your value RS power = 152 is correct, for Ra = -3 Pb = 1.Do you have a description of eRAN16.1 in hedex format?
PA for even power distribution:Pb:
Recommended Value Dual-antenna or four-antenna: DB_3_P_A(-3 dB)
Single-antenna: DB0_P_A(0 dB)
GUI Value Range 0~3 Enumeration Number/Bit N/A Unit None Actual Value Range 0~3 Default Value 1 Recommended Value Single-antenna: 0; double-antenna: 1 Initial Value Setting Source Default/Recommended Value

Thanks, I will look, but according to my expirience in our network it is imposible to increase pa without loosing of rs power, so I havent improvinf of throughput.
Not sure, try to search hdx file
here is the download link for eRAN FDD Feature Documentation eRAN16.1: https://mega.nz/file/kHYwFYwb#Qy1BIN...XxUGwwLqNv5H2U
