Technical Challenges in Achieving Ultra-Reliable & Low Latency Communication in 5G Cellular- V2X Systems

Fifth-generation (5G) has been classified as an ultra-reliable low latency communication (URLLC) by   International Telecommunication Union (ITU) to meet the varied market and industrial needs. Future cellular networks aim to fulfil the requirements to achieve seamless Ultra-Reliable & Low Latency Communication (URLLC) in delay sensitive applications also. Cellular-based Vehicle-To-Everything (C-V2X) services and its use cases are selected and reviewed.  5^th generation (5G) cellular communication can provide a promising solution by ensuring reliable and fast connectivity with low latency. This work has reviewed the challenges to achieve the URLLC in C-V2X communication. It can benefit by providing traffic safety and delay-sensitive services. Conclusion and future research directions are also discussed in the end.
