In this paper, we firstly analyze potential use cases and new requirements related to ultra-reliable and low-latency communications (URLLC) in 6G era. With the objective of showing feasibility of round-trip latency less than 100 µs, we propose a system design that introduces novel features in comparison to 5G design such as larger SCS, new frame structure and paired scheduling, and create a proof-of-concept (PoC). A verification test in a real indoor scenario shows that our system can achieve 78 μs round-trip latency and higher reliability than 5G under static environment. Furthermore, we describe challenges, potential solutions and research directions for 6G hyper reliable and low-latency communication (HRLLC).
