Poster: A TDM approach for latency reduction of ultra-reliable low-latency data in 5G

5G enhanced Vehicle-to-Everything (eV2X) is envisioned to offer simultaneous support for ultra-reliable ultra-low latency (URLLC) services such as collision warnings and high bandwidth cooperated driving services such as sensor sharing. In this paper, we propose a time division multiplexing approach and provide corresponding downlink design considerations for transmitting ultra-low latency high-priority user data over other services. Our approach can reduce Hybrid ARQ (HARQ) Round Trip Time (RTT) by half and attain the 5G eV2X goal of 99.999% reliability within 1ms under co-existence.
