New 'Mode 0' V2X category proposed for enhanced road safety

A new research paper proposes "Mode 0," a novel category for 3GPP V2X resource allocation that integrates roadside computing units (RCUs) to enhance safety communications. Current frameworks are insufficient for high-density traffic and complex hazards. Mode 0, with its spectrum from passive to active UE participation, aims to address these limitations by leveraging RCUs for sensing, communication, and local computation. Simulations using Multi-Agent Proximal Policy Optimization (MAPPO) demonstrate that Mode 0 configurations significantly improve packet delivery ratios and meet critical latency safety requirements.

    Mode 0: A New 3GPP V2X Resource Allocation Category for Roadside Computing Unit-Assisted Safety Communication

    The 3GPP V2X resource allocation framework defines two entity classes -- the base station and the vehicle UE -- and four modes across LTE and NR generations. We demonstrate that this binary taxonomy is structurally incomplete. Base station-led scheduling saturates at high-density…
