Dynamic PUCCH suggestions

Hi Experts,
For feature Dynamic PUCCH (Ericsson) which values do you recommend to:
allocThrPucchFormat1, alocTimerPucchFormat1, deallocThrPucchFormat1 and deallocTimerPucchFormat1 ?

Use default values.
In the later stage you can try reducing deallocThrPucchFormat1 from 100 to 80.

Parameters:

allocThrPucchFormat1 to 50
allocTimerPucchFormat1 to 50

deallocThrPucchFormat1 from 100 to 80
deallocTimerPucchFormat1 from 6000 to 4000

Can anyone describe how above Parameters works ?
