Hi All,
Below basic/simple calculation of power boosting on LTE Network (multi vendor), we can manipulate coverage/RSRP by boosting/de-boosting the RS power.
Recommendation value for PA and PB
PB
PA
Remark

RS -3dB but PDSCH type B +1dB

RS & PDSCH having same power

-1.77
RS +1.77 dB

RS +3 dB
2
-4.77
RS +4.77 dB but PDSCH type B -1.2 dB
3
-6
RS +6 dB but PDSCH type B -3 dB
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)
Thanks//BR
