PaPb changes Impact in DL USER THROUGHPUT
Dear friend
We have modified pbpa from 1,-3 to 0,0. Resulting we have observed +45% Throughput gain with 10% data volume increment .
But we didn't change RS power ratherthan we have increased one 20W power license in LTE as there were headroom for RRU to use power.
Kindly support to know the reason for which factor Throughput has increased.
That would be really helpful for me if you help at earliest!

Re: PaPb changes Impact in DL USER THROUGHPUT
Could you please share your charts of improvement.
reason of improvement is that new setting provide more power for PDSCH (data channel)

Hi Mounir34,
Is this Discrepancy correction value or TUning optimization to improve DL Tput?

Re: PaPb changes Impact in DL USER THROUGHPUT
I understood you are turning Power boost of on reference symbols.
It is normal for thoughput to increasea, as you have more power available for PDSCH, that carries the data.

In umts if we reduce CPICH and improve HSDPA power throughput increased but EC/no decreases..Likewise what will be the advert effect in this case.
