How do you reduce abnormal releases due to DRB reset.
I increased poll timers and T310 & T311.
Drb resets reduced but I introduced uplink sync failures.
Increase RLC retransm and harq retransm.
Under which MO are they found?
Under rlcpdcpParagroup I use maxretxthreshold of 32 for both UE and EnodeB.
if there is high L.E-RAB.AbnormRel.Radio.ULSyncFail
check both parameters: TimeAlignmentTimer & TimingAdvCmdOptSwitch
DRB is high.
poll transmit is set to 200ms and changed time alignment to 10240 , drb reduced but sync fails increased.
i changed alignment timer to infinity and Sync failures have gone back to zero but DRB has started to increase.
How do i deal with the DRB resets
