hIi,
try to change those [arameters:
nbrOfSlotsSpreadTrans and maxNumberRetransmission

[parsarka]

what values do you suggest?

[asifhaider919]

nbrOfSlotsSpreadTrans and maxNumberRetransmission have impact on RACH success rate and not SD drop

Hi

Pls cell the high SD drop sectors, remap to BCCH trx...to an extent it may get u a good solution.

Also reduce the TA by limiting power or Tilts.

@asifhaider919,
Can you also please suggest some parameters by which TCH Drops & RX Quality DL/UL can be improved??
Also do you think that there could be any degradations in the RXQ/TCH Drops after enabling antenna hopping feature?
