Abstract: Abstract Cellular vehicle-to-everything (C-V2X) is a promising area for research in wireless communication as it provides an improved performance for safe connectivity of autonomous vehicles over half duplex (HD) Direct Short Range Communication (DSRC) in terms of range, reliability and infrastructure cost. In this work, full duplex (FD) communication for Base Stations (BSs) over shared channels is presented for the first time in C-V2X networks. Three modes, Mode A, B and C have been defined based on autonomous, cellular HD and cellular FD communication. Network model has been built by plotting vehicles, pedestrians and traffic infrastructure according to Cox Process while BSs have been distributed according to 2-D Poisson Point Process (PPP) in a circular region. Mathematical model for success probability of FD communication over BSs in C-V2X networks using nearest neighbor criterion has been developed and same is compared with HD communication. Analytical results have also been compared with system model using Monte Carlo simulations. For the very first time, we have shown that success probability of FD is comparable with that of HD communication in terms of signal to interference noise ratio (SINR) ranging from −40dB to 60dB, with less than 10% degradation in the range from −15dB to 10dB, which is minimal. Other network characteristics like intensities of vehicles, roads and BSs have also shown minimal degradation (less than 10%) in performance of FD as compared to HD for C-V2X network. Effect of imperfect self interference cancellation (SIC) for different values has also been presented to highlight significance of achieving perfect SIC for FD in C-V2X networks.
