How to Evaluate gNodeB Energy Performance
Evaluating the energy plane of gNodeB according to ETSI standards
Energy plane (E-Plane) measurement requires a cross-domain test system and cross-correlation of the resulting data to gain meaningful insights into the overall energy performance of RAN components. The system should cover three domains: the ability to measure antenna RF power output, the supply of DC or AC power, and the quality of transferred data packets in terms of block error rate (BLER). As O-RAN and 3GPP rapidly evolve, equipment manufacturers must run repeated measurements to ensure continued compliance with the new standards' versions. Automating the test cases used for regression testing and report generation is the key.
To test gNodeB, test engineers must have a set of automated test cases and analytics tools based on ETSI standards. The test setup should include a user equipment (UE) emulator, a core network emulator, and a power analyzer. The UE emulator emulates stateful UE traffic and measurements. By contrast, the core network emulator terminates the calls from the UE emulator for stateful open distributed unit (O-DU) / open centralized unit (O-CU) testing. Both emulators require dimensioning for load-testing scenarios. Measuring the power consumption of the server requires a power analyzer.
