5G URLLC in Transport and Open RAN: Disaggregation RAN and Functional Splits

The industry of automobiles is entering the era of advancement. The proliferation of quick advancement in autonomous cars, electric vehicles progression in the market, evolution towards digital platforms, economical resource sharing, massive surge in data, extensive network connection demands and succession towards business models is developing intense change in the sector overall. The next generation of communication (5G) network has the potential to support and accelerate this revolution and can also play role as the backbone network for these advanced Vehicle-to-everything (V2x) automobiles communications. 5^th Generation (5G) technology exhibits number of features over previous generations of networks by offering more speed, enhanced bandwidth, much lower latency (also known as ultra-reliable and low latency communications network) and extensive simultaneous connections. Open RAN (O-RAN) architecture is majorly focused on the principles of disaggregation, virtualization and intelligent evolved Radio access Network (RAN). In this paper, we present key radio network requirements of autonomous cars and proposed a 5G radio access network (RAN) architecture suitable for handling such communication. Furthermore, interfaces of O-RAN and proposed solutions are presented as well, which will facilitate the adoption of 5G O-RAN solution for future autonomous vehicles. Finally, we present our experimented and tested results of Open RAN compliant state-of-the-art prototype.
