Sorry , there are no IBS.
Do you have an other solution?
I Think : RSCP=RSSI+Ec/No.
I want : RSCP high ->Ec/No down -> Down Tilt about Neighbour cell . Interference down ->RSSI high. that's my think . That's righ or Wrong ?

What is your target for indoor coverage by RSCP and EcNo. These values are not so extremely bad. Do you have some problems with the KPIs or customer complaint in the area of question?

Re: Help , Problem coverage 3G.
I think that problem is in Uplink direction. Ec/No -12 dB is good! You must expect problems when Ec/No is below -16dB
Solution is to implement TMA or indoor pico repeater.
What's the phone TX power ?

There are could be so many reasons. Good option is if you can do a IMSI trace and of course to check cell's KPIs for possible problems....
