Ultra-reliable and low-latency communication (URLLC) is one of the main requirements of the fifth-generation mobile communications system (5G), intended for realizing autonomous driving and telemedicine. We have proposed an early-feedback hybrid automatic repeat request (early HARQ) that provides high reliability and low latency. However, we have only studied at the link level with ideal channel estimation, and the performance in a more practical environment was not clear. In this paper, we use reference signals for channel estimation and evaluate the early HARQ in a highway environment. Through the numerical simulations, we show the superiority of the early HARQ under real conditions to a conventional closed-loop HARQ.
