摘要

新型无线车联网(NR-V2X)旨在支持先进的V2X应用，如自动驾驶、队列行驶等。增强的NR-V2X副链路资源预留机制利用了V2X应用的特点，混合自动重复请求(HARQ)方案，提高了极高的可靠性，并提供了灵活的资源指示。同时，应仔细平衡用于旁链路资源预留和系统性能增益的旁链路信令开销。本文阐述了NR-V2X增强型旁链路资源预留机制面临的挑战和具体设计问题。给出并分析了典型配置和场景下的性能。

The Enhanced Sidelink Resource Reservation Mechanism of NR-V2X

New Radio-Vehicle-to-Everything (NR-V2X) is motivated for supporting the advanced V2X applications, such as the autonomous driving, platooning, etc. The enhanced sidelink resource reservation mechanism of NR-V2X utilizes the characteristics of V2X applications, Hybrid Automatic Repeat reQuest (HARQ) scheme to improve the extreme high reliability and provide the flexible resource indications. Meanwhile, the sidelink signaling overhead for sidelink resource reservation and system performance gain should be balanced carefully. In this paper, the challenges and detailed design issues of the enhanced sidelink resource reservation mechanism of NR-V2X are depicted. The performances with typical configurations and scenarios are presented and analyzed.
