Failed to check the power parameter configurations of the cell

Hi Experts.

I’m using AAU5711a (FDD 1 carrier) with Pa=-3 / Pb=1 and RS=9.7dBm.

Using these settings I’ve 34.5dBm (2.81W).

Why cannot I use Pa=-3 / Pb=1 and RS=12.2dBm (5W)?

When I try to change it shows me error.

MOD PDSCHCFG:LOCALCELLID=171,REFERENCESIGNALPWR=122;
…
RETCODE = 0 Operation succeeded.

Sometimes it doesnot give alarm but if the cell goes down it won’t come up

Change it to Coverage 1, and observe.
Note: Are you in eRAN 15?

And yes, it’s eRAN15.
Which RF impact changing default to Coverage 1?

As far as in my knowledge, In eRAN13 by default its Coverage 1
When eran upgrades to 15 then it’s change to default_mode.

So for rs power / coverage increase depending on scenario you should select proper TM4 weight scheme.
