Radio Resource Utilization Metrics
Radio Resource Utilization (RRU) metrics provide Distributed Unit (DU) measurements
between gNodeB and the User Equipment (UE). This metric also provides operators the load
information of the radio network during the measurement time period.
Example of sample RRU
metrics.

The following table lists the JSON
definitions.
JSON | Description | Units |
|---|---|---|
RRU.PrbTotDl | Indicates the
total Downlink (DL) Physical Resource Block (PRB) usage for
all traffic. | Percentage % |
RRU.PrbTotUl | Indicates the
total Uplink (UL) PRB usage for all traffic. | Percentage % |
Active_Time_Dl | Counts the time
duration in msec that the gNb uses to transmit bits to its
serving UEs during the measurement period. | Millisecond |
Active_Time_Ul | Counts the time
duration in msec that the gNB uses to receive bits from its
serving UEs during the measurement period. | Millisecond |
RRU_MacTotVolumeDl_SNSSAI | Indicates the
total data volume transmitted in DL per S-NSSAI. | Kilobits |
RRU_MacTotVolumeUl_SNSSAI | Indicates the
total data volume received in UL per S-NSSAI. | Kilobits |
RRU_PhyTotVolumeDl | Indicates the
total Physical Layer (PHY) data volume transmitted in DL per
cell. | Kilobits |
RRU_PhyTotVolumeUl | Indicates the
total PHY data volume received in UL per cell. | Kilobits |
