eNB Integrity Introduction
Integrity Definition › EUTRAN Integrity is a measure of the Network’s ability to provide wireless end user services with end-user performance quality that meets expectations. › Integrity performance can be divided into three parts: › EUTRAN Throughput: The speed at which packets can be transferred once the first packet has been scheduled on the air interface; › EUTRAN Latency: The time it takes to schedule the first packet on the air interface, determined from the time it was received in RBS; › EUTRAN Packet Loss: The ratio of lost and transferred packets.

EUTRAN Throughput KPIs AVERAGE UE DL Thpt For calculating DL user throughput, Last TTI data_volume (kbits) (pmPdcpVolDlDrbLastTTI) is always removed as for last TTI coding is selected based on size and not the radio conditions so it doesn't reflect actual radio throughput.

EUTRAN Throughput KPIs UL LCG Traffic Volume › UE will combine the similar Qos service in the same LCG › For the UL, instead of measuring per QCI the measurement are Logical Channel Group (LCG) level LTE Training For True Optimization Team | 2016-12-01 | Page 13 (29)
EUTRAN Throughput KPIs UL LCG Traffic Volume › There actually has 4 LCG(LCG0-3),according to the 3GPP(TS23.203&36.331) QCIs(1-3) are mapping to LCG1 ，QCIs(4-6) are mapping to LCG2，QCIs(7-9) are mapping to LCG3 LTE Training For True Optimization Team | 2016-12-01 | Page 14 (29)
EUTRAN Throughput KPIs DL Latency This KPI measures the impact on the end user. NOTE that the latency will increase with more instantaneously active UEs and will also depend on the scheduling algorithm(s) being used. LTE Training For True Optimization Team | 2016-12-01 | Page 15 (29)
