C. Iliopoulos, Athanasios Iossifides, Chuan Heng Foh, Periklis Chatzimisios · IEEE Communications Standards Magazine · 2025
IEEE 802.11bd is a modern standard in the Vehicle-to-Everything (V2X) domain, designed to address the evolving demands of vehicular communications. Building on its predecessor IEEE 802.11p and considering today’s stringent communication requirements, IEEE has crafted a robust communication tool introducing the next-generation vehicle-to-everything (NGV) station. This involves significant modifications in the physical (PHY) and the medium access control (MAC) layers. This paper explores the new IEEE 802.11bd standard highlighting its predecessor’s limitations. The major PHY and MAC layer characteristics are elucidated to aid newcomers and facilitate a comprehensive comparison between the two standards. Finally, the paper underscores the impact of IEEE 802.11bd on contemporary V2X use cases and scenarios, offering concise explanations of its role in each case.
