5.1.0 Relation to RAN L2 measurement specification

28.5523GPP5G performance measurementsManagement and orchestrationRelease 18TS

When it comes to Layer 2 measurement definitions, some of the L2 measurement definitions used in the present document are referring to TS 38.314 [29]. The L2 measurement definitions in TS 38.314 [29] and in the present document have some differences:

– The measurement definitions in TS 38.314 [29] are often defined to be reported ‘per UE or per DRB’, to support MDT and Trace use cases.

– The measurements defined in the present document define L2 measurements that is aggregated and often reported per a Managed Object class (e.g. NRCellDU).

Thus, for those L2 measurements, the definition in TS 38.314 [29] is re-used in the present document, but without requirement of ‘per UE or per DRB’ reporting to be performed.
