4.1 General
All the per DRB per cell measurements and per DRB per UE measurements can be aggregated into per QoS level per cell and per PLMN ID per cell by network implementation. All the performance measurements for gNB defined in TS 28.552 [2] 5.1 can be calculated into per PLMN ID level by network implementation. Per QoS level refers to per mapped 5QI for NR SA or per QCI for EN-DC.

4.2.1.2 Packet delay
4.2.1.2.1 General
Packet delay includes RAN part of delay and CN part of delay.
The RAN part of DL packet delay measurement comprises:
– D1 (DL delay in over-the-air interface), referring to Average delay DL air-interface in TS 28.552 [2] 5.1.1.1.1.
– D2 (DL delay on gNB-DU), referring to Average delay in RLC sublayer of gNB-DU in TS 28.552 [2] 5.1.3.3.3.
– D3 (DL delay on F1-U), referring to Average delay on F1-U in TS 28.552 [2] 5.1.3.3.2.
– D4 (DL delay in CU-UP), referring to Average delay DL in CU-UP in TS 28.552 [2] 5.1.3.3.1.
The DL packet delay measurements, i.e. D1 (the DL delay in over-the-air interface ), D2 (the DL delay in gNB-DU), D3 (the DL delay on F1-U) and D4 (the DL delay in CU-UP), should be measured per DRB per UE.
NOTE: The delay measurements D1, D2 and D4 are also applicable for EUTRA in case of EN-DC related DL delay measurements on the MN side.
The RAN part (including UE) of UL packet delay measurement comprises:
– D1 (UL PDCP packet average delay, as defined in clause 4.3.1.1).
– D2.1 (average over-the-air interface packet delay, as defined in 4.2.1.2.2).
– D2.2 (average RLC packet delay, as defined in 4.2.1.2.3).
– D2.3 (average delay UL on F1-U, it is measured using the same metric as the average delay DL on F1-U defined in TS 28.552 [2] clause 5.1.3.3.2).
– D2.4 (average PDCP re-ordering delay, as defined in 4.2.1.2.4).
The UL packet delay measurements, i.e. D1(UL PDCP packet average delay), D2.1(average over-the-air interface packet delay), D2.2(average RLC packet delay), D2.3(average delay UL on F1-U) and D2.4(average PDCP re-ordering delay), should be measured per DRB per UE. The unit of D1, D2.1, D2.2, D2.3 and D2.4 is 0.1ms.
NOTE: The delay measurements D1, D2.1, D2.2 and D2.4 are also applicable for EUTRA in case of EN-DC related UL delay measurements on the MN side.
For non CU-UP and DU split case, RAN part of packet delay excludes the delay at FI-U interface, i.e. D2.3 and D3.
If network disables the PDCP re-ordering function, the value of Average PDCP re-ordering delay i.e. D2.4 should be set to 0.
For the QoS monitoring in TS 23.501 [4], RAN informs the RAN part of UL packet delay measurement, or the RAN part of DL packet delay measurement, or both to the CN.

|
Definition |
Uu Packet Loss Rate in the DL per DRB per UE. One packet corresponds to one RLC SDU. The measurement is done separately per DRB. Detailed Definition: , where explanations can be found in the table 4.2.1.5.1-2 below. |
NOTE 1: Packet loss is expected to be upper bounded by the PER (packet error rate, as defined in TS 23.501 [4]) of the DRB which takes values between 10-6 and 10-2. The statistical accuracy of an individual packet loss rate measurement result is dependent on how many packets have been received, and thus the time for the measurement.
