Time in minutes for automatic removal of an unused TermPointToGNBDU MO. RC13 carrierAggregation Enable/disable NR Carrier Aggregation of max 4CC 0 = Disabled 1 = Enabled RC14 pdcpOutOfOrderDelivery Switch between using pdcp outOfOrderDelivery 0 = pdcpOutOfOrderDelivery false 1 = pdcpUutOfOrderDelivery true Classification File: /proj/rbs-g2-tmp/fem051/UpData/CXP2010045_5/R17B31/UP/ppSysConstClassifiedLm/bin/sysconst_ClassifiedSCsPp.txt Id Name Description PP1 ppLinkInactivitySupervisionPeriod The timeout value to use when supervising inactive links before removing them. PP10 nrDlpdcpSpsTargetTimeMs Replaced by dlPdcpSpsTargetTimeNr and dlPdcpSpsTargetTimeLte PP11 dlpdcpSpsLowPduqKb The flow control low pdu queue threshold. If the PDU queue (that is the data transmitted to RLC but not yet acknowledged by the UE) is shorter than this flow control will set a default bit rate, even if radio throughput is low. PP12 dlpdcpSpsPeriod The period in milliseconds between flow control bitrate policy updates.It should be large enough so that new feedback has arrived every period.Smaller value means more accurate flow control.It should not be set to a value lower than tStatusProhibitDl on any of the legs. PP15 dlpdcpSpsThresholdTimeMs Input parameter to calculate threshold to activate flow control for a given bearer.The age of the oldest unacknowledged packet for a bearer in milliseconds is compared to (dlpdcpSpsThresholdTimeMs + dlpdcpSpsLinkTimeFactor * measured C5U RTT). PP16 dlpdcpSpsLinkTimeFactor Input parameter to calculate activation threshold and target buffer depth for flow control.The C5U link delay is multiplied by this factor and a
