6G Digital Twins Use Cases and Requirements explores the transformative role of Digital Twin (DT) technology in the 6G era. By leveraging advanced AI, real-time data processing, and joint communication and sensing, 6G enhances DTs’ ability to simulate, analyze, and optimize physical systems with unprecedented accuracy. These improvements unlock new opportunities in sectors like manufacturing, healthcare, and smart cities, where DTs enable predictive maintenance, resource optimization, and real-time monitoring. The combination of distributed computing and ultra-low latency connectivity allows complex DT models to function seamlessly across multiple devices, driving efficiency and innovation in urban planning, industrial automation, and network management.

This white paper highlights three key DT use cases poised for significant growth: Network Digital Twins (NDT), Industrial Automation DTs, and Smart Cities DTs (SCDT). NDTs create virtual replicas of networks to optimize performance, enhance mobility management, and enable network slicing, fostering business opportunities in predictive analytics and operational efficiency. Industrial Automation DTs drive smart manufacturing by enabling predictive maintenance, process simulation, and energy management, enhancing both productivity and sustainability. SCDTs revolutionize urban management by creating digital models of cities to improve planning, optimize resources, and engage citizens in governance. While DT technology presents challenges such as data integration, security, and scalability, the evolution of 6G will address these issues, making DTs more robust and indispensable across industries.
