Hi Sewashi
Path imbalance=Path Loss(DL)-Path loss(UL)

Path imbalance=Path Loss(UL)-Path loss(DL),whatever.

thanks bijoy. in nokia, the formula for ave link imbalance is

(2x ave BS power + ave DL signal strength) – (2x ave MS power – ave UL signal strength)

is this path loss?

A little correction.
DL path loss(dBm) =Avg BS power – combiner loss – Avg DL signal strength
UL path loss(dBm)= Avg MS power – Avg UL signal strength.

thanks bijoy. heres the actual formula i copied from nokia documentation. why is it dat ave_dl_sig_str is positive? can you explain?

2*sum(ave_BS_power)/sum(power_denom2)+sum(ave_dl_sig_str)/sum(power_denom3)
-2*sum(ave_MS_power)/sum(power_denom1)-sum(ave_ul_sig_str)/sum(power_denom4)

Counters from table(s):
p_nbsc_power
Unit = dB
