AbstractWith the rapid advancements in mobile Internet and smartphones, data traffic in current mobile communication systems is growing exponentially. At the same time, demands for lower latency, increased robustness, and higher energy efficiency are becoming more stringent. In response, 5G technology promises to meet these demands and is currently garnering extensive research interest from both industry and academia. 5G is not just an incremental improvement over its predecessors; it is a transformative technology designed to revolutionise mobile communications. By offering significantly higher speeds, reduced latency, and the ability to connect a massive number of devices simultaneously, 5G stands to impact a wide range of applications from autonomous vehicles to smart cities, healthcare, and beyond. Significant progress has been made in the standardisation and field deployment of 5G networks. Organisations such as the 3rd Generation Partnership Project (3GPP) have been instrumental in developing the standards that define 5G technologies. Moreover, various pilot projects and commercial deployments have been initiated around the world, showcasing the practical capabilities of 5G in real‐world environments.
