Abstract. This paper discusses advancements in 6G communication technologies, focusing on
Ultra-Reliable Low-Latency Communication (URLLC) and Integrated Sensing and
Communication (ISAC). URLLC aims to achieve low latency (under 1 ms) and high reliability
(down to 10^-6) crucial for applications such as autonomous driving, remote surgery, and industrial
automation. ISAC integrates communication and sensing functions, improving efficiency and
enabling new services in various industries, including healthcare, transportation, and
manufacturing. This integration supports real-time operations and enhances the performance of
smart systems. The paper highlights technological enablers, including ultra-dense networks,
intelligent relaying, and advanced sensing techniques, necessary for implementing URLLC and
ISAC in the 6G era. The discussion extends to the potential challenges and future research
directions, emphasizing the need for resource optimization and security in 6G networks. The study
suggests that combining AI with URLLC and ISAC can address latency and reliability
requirements, proposing a unified approach for future communication systems.
