Title

Reliability Maximization with Location-Based Scheduling for Cellular-V2X Communications in Highway Scenarios

Abstract
Advanced applications in intelligent transport systems (ITS) are based on V2X (vehicle-to-everything) communications. In order to share information about, e.g., vehicle status, critical events or perceived objects in the vicinity, respective services suggest direct communication links (device-to-device) among vehicles, as introduced in ITS-G5 and Cellular-V2X. A major challenge for direct communications systems is the utilization of available radio resources. In this work, we present a resource scheduling scheme based on vehicle locations, aiming to maximize the reliability of message transmission in highway scenarios, considering a given band-width. The scheme consists of two steps: first we determine the optimal distance between vehicles utilizing equivalent radio resources. We extend our previous work and provide a closed form solution for the outage probability. The quasi-convex expression can be solved with standard optimization algorithms. In the second step, we propose radio resource allocation strategies that rely on the optimal scheduling distance. Finally, we evaluate the performance of our proposed scheme compared to a fixed scheduling distance.
