🤖 AI Summary
This study addresses the absence of a standardized end-to-end energy efficiency evaluation methodology for Open RAN, which hinders fair comparison of diverse hardware and software solutions under varying network conditions. To bridge this gap, the work proposes the first standardized end-to-end energy efficiency testing framework tailored for Open RAN. The framework integrates commercial RAN emulators, real-world operator network topology data, and xApp/rApp cooperative control mechanisms, enabling cross-vendor energy efficiency benchmarking under uniform experimental conditions. Experimental results demonstrate that the proposed approach achieves up to a 57% improvement in energy efficiency compared to baseline solutions, highlighting its significant potential for optimizing sustainable RAN deployments.
📝 Abstract
Energy efficiency (EE) is one of the key challenges for contemporary and future mobile networks, including within the Open Radio Access Network (O-RAN) architecture. However, there is a significant gap in common procedures for comparing the EE of both hardware (HW) and software (SW) solutions offered by various vendors. Usually, EE improvements of both SW and HW solutions are demonstrated in a specific scenario defined by individual vendors avoiding comparisons and benchmarking under various network conditions. This paper outlines the need for unified end-to-end (E2E) EE testing for O-RAN. First, it analyzes the standards to identify missing parts. Based on the analysis, a novel O-RAN E2E EE Testing framework is proposed. The framework aims to test the EE of the xApp/rApp pair cooperating on the cell on/off switching using a commercial RAN emulator and real-world network topology data from a mobile network operator (MNO). The test results show up to 57% improvement in EE compared to the baseline.
