A.6 Monitoring of physical radio resource utilization

28.5523GPP5G performance measurementsManagement and orchestrationRelease 18TS

The physical radio resource utilization measurements could provide operators the load information of the radio network during the measurement time period. The physical radio resource utilization measurements should reflect the average usage and the usage distribution of the radio resource of the physical layer. The measurements can make the operator to be aware of whether a cell has ever experienced high load or not in the monitoring period, and is a key input to network capacity planning and load balancing.

Network slicing is an important feature in 5GS, monitoring physical radio resource utilization per S-NSSAI is helpful for opeators to be aware of the load.
