As 5G-A networks evolve, low-latency and high-reliability communication (Ultra-Reliable Low-Latency Communication, URLLC) becomes critical for supporting applications such as autonomous vehicles, remote surgery, industrial automation, and immersive augmented reality. This paper explores the advancements required to achieve these stringent performance metrics in 5G-A networks. We discuss the underlying technologies, including edge computing, network slicing, and the integration of AI for dynamic resource allocation, that will help reduce latency and ensure reliable communication. The paper also addresses challenges such as signal interference, network congestion, and the trade-offs between throughput and latency. Furthermore, we examine the role of 5G-A’s advanced infrastructure, such as massive MIMO and terahertz frequencies, in achieving these goals. Finally, the paper highlights the importance of end-to-end reliability and the potential of URLLC to transform industries by enabling real-time, mission-critical services in a hyper-connected world.

摘要

As 5G-A networks evolve, low-latency and high-reliability communication (Ultra-Reliable Low-Latency Communication, URLLC) becomes critical for supporting applications such as autonomous vehicles, remote surgery, industrial automation, and immersive augmented reality. This paper explores the advancements required to achieve these stringent performance metrics in 5G-A networks. We discuss the underlying technologies, including edge computing, network slicing, and the integration of AI for dynamic resource allocation, that will help reduce latency and ensure reliable communication. The paper also addresses challenges such as signal interference, network congestion, and the trade-offs between throughput and latency. Furthermore, we examine the role of 5G-A’s advanced infrastructure, such as massive MIMO and terahertz frequencies, in achieving these goals. Finally, the paper highlights the importance of end-to-end reliability and the potential of URLLC to transform industries by enabling real-time, mission-critical services in a hyper-connected world.
