Toward AI-Enabled Green 6G Networks: A Resource Management Perspective

The development of 6G wireless networks is driven by the pressing need for reliable connectivity in the increasingly intelligent Internet of Things (IoT) ecosystem. The goal of these networks is to seamlessly connect individuals, devices, vehicles, and resources such as the cloud. However, the heterogeneity and complexity of 6G due to the proliferation of devices, diverse applications, and the need for green and sustainable communication networks, pose significant Resource Management (RM) challenges. Furthermore, the stringent requirements of 6G networks for Quality-of-Service (QoS), scalability, intelligence, and security can make traditional RM approaches ineffective, particularly considering Energy Efficiency (EE). In response to these challenges, Artificial Intelligence (AI) has been considered to provide green RM. AI techniques can be used to efficiently manage network resources, balance energy demands, optimize EE, and integrate Energy Harvesting (EH). This paper examines 6G networks from an AI perspective to optimize resource allocation, minimize energy consumption, and maximize network performance. The focus is on RM within these networks considering Radio Resource Management (RRM), Computing and Caching Resource Management (CCRM), and Communication Network Resource Management (CNRM). The emphasis is on RM within the Cellular Network Infrastructure (CNI) and Machine Type Communications (MTC). AI models for efficient resource utilization to enhance EE and network performance are investigated. It is shown that AI plays a pivotal role in achieving green RM within 6G networks. Future research directions are outlined for intelligent networks to meet the growing demands and emerging challenges.
