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.
