Joint Autonomous Resource Selection and Scheduled Resource Allocation for D2D-Based V2X Communication

In this paper, we investigate the resource allocation problem for D2D-based Vehicle-to- Everything (V2X) communication. There are two resource allocation modes for V2X sidelink communication: autonomous resource selection and scheduled resource allocation which is further divided into 2 categories-the dedicated mode and the reuse mode. Considering that each V2X message is arranged with the independent ProSe Per-Packet Priority (PPPP) and V2X sidelinks require stringent latency and reliability, therefore, in this paper, we propose a new joint autonomous resource selection and scheduled resource allocation approach to maximize the sum of the information values of all users. Our proposed scheme not only considers the user's PPPP but also takes into account the user's communication reliability, while guaranteeing the quality of service (QoS) of both Pedestrian user equipments (P-UEs) and Vehicle user equipments (V-UEs). A comprehensive performance evaluation is conducted to demonstrate the efficacy of the proposed scheme.
