Abstract

In conventional C-V2X, the resource pool used by all users for transmission is unified, regardless of the user identity. Moreover, NR-V2X sidelink feature allows users to randomly select a resource and maintain it for several periods, resulting in interference. In this paper, a separate resource pooling algorithm is introduced, in which the number of resources used by different users is dynamically changed with a fuzzy inference system, considering the current resource status and number of neighbours. Numerical results demonstrate the superiority of the proposed mechanism, in terms of Packet Reception Ratio (PRR) as well as the data Update Delay.

车辆与基础设施通信的动态分离资源池算法

在传统的C-V2X中，无论用户身份如何，所有用户用于传输的资源池都是统一的。此外，NR-V2X的副链路特性允许用户随机选择一个资源并维持几个周期，从而产生干扰。本文提出了一种单独的资源池算法，该算法在考虑当前资源状态和邻居数量的情况下，通过模糊推理系统动态改变不同用户使用的资源数量。数值结果证明了该机制在分组接收比（PRR）和数据更新延迟方面的优越性。
