Sipos Csaba sipos.csaba at kvk.uni-obuda.huHi Jacob,
Thanks for the info, will try that.
What algorithm (PCU) would you prefer if the goal is to maximize the single UE throughput?
Regards,
Csaba

That's normal in the default case, since the MS will have to issue a
RACH to get an uplink TBF for the response. You can allow to keep the
PACCH open for a longer time by configuring
pcu
dl-tbf-idle-time 2000
This keeps the DL TBF open for the time given (in ms) by periodically
sending LLC dummy commands.
