Today, i've get information that -112dBm this is NodB sensetivity.

Thanks, i've found it,but i need UL . Another step will be to campare 2 methods of calculating of % UL Load Factor , and compare it.
I don't like method with User number, because we play with MaxEqvUserNumber - it helps to reduse power congestion on some high loaded cell. But on another hand if i will increase MaxEqvUserNumber - UL load Factor will decrease....looks strange.
For example current ULEqvUserNum - 40, Max 80 %UL load Factor - 50%. But if i set Max to 120 - %UL load factor will be 33%?
If i will use RTWP, it will be more usefull, because RTWP will show real load on cell.
On our network we have some cells, which cover hostels. It means that in one place we have more than 100 users in BH and of course high PS RAB Failure due power congestion. We already have done everything what we can - we have added second carrier (we can not add more than 2 ), we increased tilt (to avoid extra users), but congestion still exists.
But, when we have changed ULEqvUserNum from 80 (default Huawei value) to 120 -140 - congestion becames near 0. Of cause we can guess, that if we increase ULEqvUserNum we loose something else. But I don't know exactly -what. And on another hand we can increase user perception and KPI's.
I don't think, that they have direct relation (ENU and RTWP). I mean, that you have only 3 algorithm types. 2 of them based on RTWP and TCP. 1 - based on ENU. As i understand Huawei has his own experience, how many ENU corresponds to each service. In accordance with algorithm - Eqvuser (total)+Eqvuser (new) should be less than MaxULEqvUserNum.....otherwise admission will be rejected.

Today, i've finished calculation for all cells inside one cluster with granularity -30 min (i use formula with RTWP and Back_noice). Result looks good. Values from 0 to 93%. But one problem, some of them has negative value. It means that RTWP lower than Back_noise. Is this normal? What do you think?
