论文摘要
在蜂窝车到所有用途（C-V2X）中数据流的优先级可能会导致低优先级流的不利数据包延迟。本文将每辆车的多个候选单框架资源（CSR）作为解决方案进行了研究。它提出了一种方法，以根据总车辆的数量来确定每辆车的CSR数量，并在其中分配多个数据流以同时传输。数值结果凸显了所提出的方法的可实现的延迟收益及其对数据包碰撞的影响可忽略不计。
Prioritization of data streams in cellular vehicle-to-everything (C-V2X) may lead to unfavorable packet delays in low priority streams. This paper studies the allocation of multiple candidate single-subframe resources (CSRs) per vehicle as a solution. It proposes a methodology to determine the number of CSRs for each vehicle based on the number of total vehicles, and to assign the multiple data streams among them for simultaneous transmission. The numerical results highlight the achievable delay gains of the proposed approach, and its negligible impact on packet collisions.
