there are no optimal values… there are default values, and then there are optimized values, for specific cells.
to make more agressive settings:
decrease L_RXLEV_DL_L by 3dB-to-6dB
decrease U_RXLEV_DL_L by 3dB-to-6dB
decrease A_LEV_PC by 1
And finally, reduce by “1” the parameters related to PC and which slow down PC command / ack messages. Unfortunately, i don’t recall their exact names. They contain the string “INT” and “ACK”.
Instead of 2 and 1, set 1 and 0 (ie. -1 for each of them).
And that’s about it.
