N NRM solution set (3GPP TS 28.541, annex D); YANG-based 3GPP NR and NG-RAN NRM solution set (3GPP TS 28.541, annex E). 6.5.5 Performance Management Generation and collection of performance measurements is an essential part of the 3GPP management framework, particularly important for NG-RAN. The performance measure- ments are used as input for computation of KPIs for NFs. The corresponding management services include: Measurement job control service Performance data file reporting service Performance data streaming service Performance threshold monitoring service. The NRM-based measurements control framework introduced by 3GPP allows alignment of performance measurements control with the service-based management architecture. This control framework is based on generic provisioning services with operations, such as: 8 The term NRM has been historically used in 3GPP. 6.5 Operations, Administration, and Management Create Information Object Class (IOC); Get/modify IOC attributes, etc. The corresponding NRM extensions include MeasurementControl IOC defined in 3GPP TS 28.622, which enables control over generation of measurements at relevant managed objects and their delivery to the network data collectors. This work started in Release-15 and continued in Release-16 with the specification of NRM for Trace Session Control. 3GPP TS 28.552 specifies an extensive set of performance measurements reported by the gNBs; the following are some important categories: Radio resource utilization statistics, including downlink/uplink total PRB usage, and breakdown to PRBs used for data traffic; UE throughput distribution; PDU session management statistics, including successful and failed PDU session setup requests; Mobility management statistics, including inter-(intra-)gNB successful and failed han- dover requests; Transport Block (TB) related measurements; DRB setup management statistics, including successful and failed DRS setup requests; RF measurements, including MCS distribution in PDSCH and PUSCH and Wideband CQI distribution;
