Vehicular communications promise improved road safety by sharing information, with current standards IEEE 802.11p and LTE‑V2X, while 5G NR‑V2X and IEEE 802.11bd are emerging technologies under evaluation. The study evaluates and compares the PHY layer performance of NR‑V2X, LTE‑V2X, 802.11bd, and 802.11p to determine the most suitable technology for V2V communications. We assess PHY layer performance of these technologies in V2V scenarios. Results indicate NR‑V2X outperforms LTE‑V2X, 802.11bd, and 802.11p in reliability, range, latency, and data rates, while 802.11bd still offers improved reliability, range, and throughput over 802.11p.
Vehicular communications and connected cars have an eminence potential to improve road safety and reduce the number of accidents by sharing information with their surrounding. The state of the art technologies to enable vehicular communications are IEEE 802.11p and LTE-V2X. A number of studies and field trials are carried out to evaluate their performance and suitability in various scenarios. On one hand 3GPP (3rd Generation Partnership Project) is working on the next generation V2X technology 5G NR-V2X to address new use cases and improve the performance. On the other hand, an IEEE 802.11 study group NGV (next generation V2X) is identifying new use cases and requirements to define a possible amendment IEEE 802.11bd. In this paper, we evaluate and compare the PHY layer performance of these upcoming technologies for vehicle-to-vehicle (V2V) communications. The purpose of this study is to identify which technology is more suitable for V2V communications. Our results show that NR-V2V is expected to outperform all other standards (even IEEE 802.11bd) in terms of reliability, range, latency and data rates. However, IEEE 802.11bd is expected to be more reliable with improved range and throughput compared to IEEE 802.11p.
