Achieving Energy Efficiency in Open Radio Access Networks (ORAN) using xApps

Abstract

Open Radio Access Networks (ORAN) have emerged as a transformative approach to building flexible and modular wireless networks. The disaggregated architecture of ORAN enables the development and deployment of innovative applications, known as xApps, which play a crucial role in optimizing network performance and energy efficiency. This paper explores the potential of xApps in achieving energy efficiency in

ORAN and examines the challenges faced by developers in this context. We investigate the available open platforms for xApps development and testing, highlighting their features and limitations. Furthermore, we delve into the specific strategies employed by energy-efficient xApps, such as dynamic resource allocation, sleep mode management, and intelligent traffic steering.

The paper also emphasizes the importance of standardization efforts and collaboration among stakeholders to establish best practices for xApps development and deployment.
