qrxlevmin range

[ohms_law]

I am setting UE parameters in an RBS6601 site. I am getting an error with the qrxlevmin setting that I am out of range @ -115 dBm. That value is in range and Element Manager will not let me set it. I can set it to -114, -116, etc, just not -115.





Is there a dependency that I am unaware of? This works in R24, but the error occurs in R29.





Thanks.

ALL is normal, depending on your LTE software Load, E******* changes the increments from 1db to 2 db increments after I think L13A for LTE/. i.e. you can only set even numbers. hope this helps

qRxLevMin must be tuned to ensure that the area, where a UE can camp on a cell aligns with the area in which the network can serve the UE in a satisfactory way. Typical values are in the range of -120 dBm to -135 dBm, depending on system configuration, UE performance, inerference levels, and desired service level.

as already indicated, the resolution for this parameter is 2 , so you can't set an odd number

you can check all the details of a parameter with the command: mom . nameOfTheParameter in AMOS

exeample on a L14A site

XXXX_LTE> mom . qRxLevMin

Thanks. That helps a lot, but I am getting the same error whenever I attempt to change the Channel Number in the EUtranCellFdd Managed Object.

That is, I select the action change frequency and even though I am not changing the qRxLevMin, I get the same error that qRxLevMin is out of range @ -115.

Does that make sense. How are they related? It is very frustrating as I cannot change the channel on my Radio Head because of this failure.
