论文摘要
可重新配置的智能表面（RISS）有助于为传统车辆网络的发展铺平道路。话虽如此，第三代伙伴关系项目（3GPP）面临着关于不久的将来的RIS AID车辆（V2X）解决方案的许多公开挑战。为了应对这些挑战并刺激未来的研究，本文着重于RIS AID的V2X通信的前瞻性传播设计。特别是，通过利用RISS及其变体来增强两种V2X SIDELINK模式，然后是定制的传输框架结构，将传输工作划分为不同阶段。接下来，开发了有效的渠道跟踪和资源分配技术，以在低顶和复杂性下获得屏蔽增益。最后，强调了有前途的研究主题，并为Risaid的V2X系统提出了未来的3GPP标准化项目。
Reconfigurable intelligent surfaces (RISs) assist in paving the way for the evolution of conventional vehicular networks to autonomous driving. Having said that, the 3rd Generation Partnership Project (3GPP) faces numerous open challenges concerning the RIS-aided vehicle-to-everything (V2X) solutions of the near future. To tackle these challenges and to stimulate future research, this article focuses on the prospective transmission design of RIS-aided V2X communications. In particular, two V2X sidelink modes are enhanced by exploiting RISs and their variants, followed by a customized transmission frame structure that partitions the transmission efforts into different phases. Next, effective channel tracking and resource allocation techniques are developed for attaining a high beamforming gain at low overhead and complexity. Finally, promising research topics are highlighted and future 3GPP standardization items are proposed for RISaided V2X systems.
