A.9 Monitoring of UE Throughput in NG-RAN

Keeping track of UL and DL UE throughput in the NG-RAN is essential, to ensure end user satisfaction and well-functioning and well configured cells and scheduling features.

The restricted UE throughput per mapped 5QI will show the scheduling efficiency and QoS priority handling in the gNB and the ratio between unrestricted and restricted volume will show the gNB ability to handle small data transfers efficiently.

To be able to monitor the spread of throughput within the cell, and estimate the ratio of satisfied users, the throughput distribution measurement can be used.

When network slicing is supported by the NG-RAN, multiple s S-NSSAIs may be supported. The UL and DL UE throughput for each S-NSSAI is then of importance to the operator to pinpoint a specific performance problem.

For RAN sharing scenarios, the UL and DL UE throughput in each PLMN is of importance to pinpoint performance problem in a specific PLMN.
