RSRP and RSRQ

[jbada]

Hi Forum

I would like to ask your opinion about nominal planning for LTE (10 MHz) in a big cities for RSRP and RSRQ and maybe SINR

I am currently working in a nominal plan and I consider the following values for indoor coverage

RSRP >= -120 dBm at 90% coverage area

RSRQ >=-18 dB at 100% load at 80% coverage area

SINR >= -3 dB

Do you thing this values are OK or not?

How can we calculate more accurately?

Can anyone share some values for outdoor cov?

Thanks forum

It depends:

-cluster type?
-throughput target at the cell edge?

Its a nice topic , If you can please give some details on how your doung the link budget , so we all can learn from it :)

Hi

These values are for Nominal Planning to try to achieve maximum THPUT in the whole cluster. Several clutter types have been considered.

Hi,

In a data network, the approach to the link budget is a bit different.
The network would be desing according to the desire througput at the cell edge for that cluster. (not according to the coverage)
From theoretical point of view, if u want to know the througput at the cell edge, with that SINR, use the Shannon formula graph.

In order to know the maximun throughput in one specific cluster u would need to do predictions. (statics or Montecarlo)

BTW, RSRQ is not really take into account on the link budget.


I have post a few LTE link budgets, maybe they could be helpful.

hi Jbada,

these values are discussed with customer, values which u hv showed are just ok..not so good.

AT&T use these values for the design, but some other operators goes for mach batter design.

i think you will be doing the calculation based on monte carlo , the traffic plot is usually a 1 day traffic based.

in LTE , number of servers are the very important.

do you have nominal value for the KPI ?
