Abstract：Intelligent outgoing promotes vehicles networks from supporting on-board information services to the next generation that supports V2X services. In order to meet the development needs of Vehicles networks, the 3GPP standard has developed two communication modes, PC5 interface and Uu, for LTE-V. Combined with the characteristics of LTE-V services, this paper introduces the Mode3, Mode4 and SPS enhanced scheduling algorithms，and the advantages and disadvantages of each algorithm, which lays a foundation for the communication requirements of low-latency and high-reliability among V2V, V2I and V2P.
Abstract：At this stage, as China is in an important period of transformation and upgrading of manufacturing industry and innovation and development of emerging technology industries, the emerging intelligent industry V2X is increasingly receiving national attention. Based on the fifth-generation mobile communication system(5G), the compatibility between the V2X Internet of Vehicles(IoV) system and the fixed satellite service at 6 GHz is researched through the deterministic calculation, via using the communication model provided by the relevant recommendations and reports of the International Telecommunication Union(ITU). The results show that the V2X IoV system is compatible with fixed satellite service(FSS) at 6 GHz frequency band.

Abstract：Ultra-reliable and low latency communication(URLLC) is one of the three big scenarios in 5G, and is paid more and more attention now. Internet of vehicle is one of the application about URLLC, and it has high requirement about reliability of information transmission. In order to improve the reliability and robustness of transmission, several transmission schemes of Multi-TRP based URLLC is introduced from the perspective of SDM, FDM and TDM, and the merit and demerit of these schemes are compared with each other. In addition, a new method of indicating dynamic switching between these schemes is proposed, and the performance is evaluated. Based on the simulation results, significant performance gain can be obtained by the scheme of dynamic switching.
Abstract：Combined with the fusion technology of MEC and C-V2X，a green wave transit system based on 5G vehicle network is studied, and relevant researches are made on the green wave transit model, application of MEC and collaborative control management. This system can realize real-time vehicle-road coordination with lower time delay, and realize coordinated perception of traffic light information at multiple intersections, so as to realize the continuity of the green wave priority, reduce traffic congestion at intersections and improve transport efficiency.
Abstract：Due to the short board of delay and reliability, LTE V2X can only be used in assistant driving and primary driving scenarios. It is necessary to meet the future demand of advanced automatic driving by updating technology. The opportunity 5G cellular car networking NR V2X emerges as the times require. Combining with the standard process of 3GPP 5G NR V2X, this paper focuses on the key technical requirements and solutions of 5G NR V2X based on the analysis of application scenarios for advanced automatic driving, and introduces the current standardization progress.
