摘要:

随着通信和计算的快速发展,互联车辆的概念应运而生,以提高驾驶安全性,交通效率和信息娱乐体验。由于单个车辆上的传感器和信息处理能力有限,车辆网络(VehicleNetworks,VNECs)对于实现车联网起着至关重要的作用。为了实现在路上更紧密的合作,超可靠和低延迟通信(URLLC)成为未来VNNXP不可或缺的组成部分。然而,传统的无线网络的设计目标是最大化频谱和能量效率,而不管URLLC的充分考虑。为此,本文研究了构思互联车辆专用URLLC VNCET的挑战和解决方案。具体而言,底层应用场景首先呈现各种车载通信模式。然后,URLLC的要求和潜在的挑战进行了讨论的VNNEE。从物理层和介质访问控制层两个方面讨论了建立URLLC虚拟网络的解决方案,包括延迟和可靠性优化框架,以及应用该框架的案例分析。最后指出了几个有待进一步研究的方向。

英文摘要:

With the rapid development of communications and computing, the concept of connected vehicles emerges to improve driving safety, traffic efficiency and infotainment experience. Due to the limited capabilities of sensors and information processing on a single vehicle, vehicular networks (VNETs) play a vital role for the realization of connected vehicles. To achieve the closer cooperation on the road, ultra-reliable and low-latency communications (URLLCs) become the indispensable components of future VNETs. However, traditional wireless networks are designed with the objective of maximizing spectral and energy efficiency regardless of adequate consideration of URLLCs. To this end, this article investigates the challenges and solutions of conceiving URLLC VNETs dedicated for connected vehicles. Specifically, the underlying application scenarios are first presented with various vehicular communication patterns. Then, the URLLC requirements and potential challenges are discussed for VNETs. We also discuss the solutions to establish URLLC VNETs from the aspects of physical and media access control layers, including the optimization frameworks for latency and reliability, as well as the case studies of employing such frameworks. Finally, several open research directions are pointed out.
