How to improve LTE throughput through PA PB and RS power?

Dear All.
How to improve LTE throughput through PA PB and RS power?

You can reduce RS power to increase PA and PB but you will reduce the coverage.

What are the parameters as Pa,Pb in Ericsson to control the power under the site ?

'You Can Keep Pa and Pb=0 and RS Power Depend on You Hardware like 212 or 182.

So You can get better power for PDSCH.
