| contents | This paper presents a detailed and flexible power consumption model for Radio Units (RUs) in O-RAN using the ns3-oran simulator. This is the first ns3-oran model supporting xApp control to perform the RU power modeling. In contrast to existing frameworks like EARTH or VBS-DRX, the proposed framework is RU-centric and is parameterized by hardware-level features, such as the number of transceivers, the efficiency of the power amplifier, mmWave overheads, and standby behavior. It enables simulation-driven assessment of energy efficiency at various transmit power levels and seamlessly integrates with ns-3's energy tracking system. To help upcoming xApp-driven energy management strategies in O-RAN installations, numerical research validates the model's capacity to represent realistic nonlinear power scaling. It identifies ideal operating points for effective RU behavior. |
