摘要

C-V2X (Cellular Vehicle-to- everything)是智能网联汽车(ICV)和智能交通系统(ITS)的重要使能技术。在第三代合作伙伴计划(3GPP)中，LTE (Long Term Evolution)-V2X的标准化已经完成，但拥塞控制机制尚未明确，有待实施。本文主要研究LTE-V2X中的拥塞控制机制。介绍了与拥塞控制机制相关的测量和可调传输参数。然后提出了LTE-V2X中拥塞控制机制的实现。给出了现场测试结果，以验证系统性能指标的有效性。

Research, Implementation and Practice of Congestion Control Mechanism in LTE-V2X

C-V2X (Cellular Vehicle-to-Everything) is the vital enabling technology of Intelligent Connected Vehicle (ICV) and Intelligent Transportation System (ITS). Standardization of LTE (Long Term Evolution)-V2X has been completed in Third Generation Partnership Project (3GPP), but the congestion control mechanism is not specified and up to implementation. This paper mainly focuses on the congestion control mechanism in LTE-V2X. The measurements and adjustable transmitting parameters related to the congestion control mechanism is introduced. Then the implementation of congestion control mechanism in LTE-V2X is proposed. The field test results are presented to verify the effectiveness with system performance metrics.
