基于URLLC技术在电动汽车的应用

电动汽车技术的不断发展和电动汽车应用规模的增大使得研究电动汽车及V2X互动具有重要的意义。同时,随着5G技术的成熟,由5G无线技术的出现带来的超可靠低延迟通信(URLLC)技术,以其超可靠低延迟的特性,将广泛应用于无人驾驶电动汽车领域。文中研究讨论采用F-OFDM降低URLLC时延及应用于无人电动汽车的可行性,提出了5G+V2X网络实现无人驾驶电动汽车的生态网络。采用F-OFDM在原有OFDM载波带宽基础上,划分多个不同参数的子带,对于子带进行滤波。5G+V2X生态网络快速的机动性和下一代无人驾驶电动汽车网络的密集交通推动无人驾驶电动汽车的发展,基于URLLC进行超可靠、低延迟的数据交互服务。

Application based on URLLC technology in electric vehicles

With the continuous development of electric vehicle technology and the increase of the application scale of electric vehicle,it is of great significance to study the interaction between electric vehicle and V2X.Meanwhile,with the maturity of 5G technology,the ultra-reliable and low-delay communication(URLLC)technology brought by the emergence of 5G wireless technology will be widely applied in the field of driverless electric vehicles due to its ultra-reliable and low-delay characteristics.In this paper,the feasibility of using F-OFDM to reduce the extension of URLLC to unmanned electric vehicles is discussed,and the 5G+V2X network is proposed to realize the ecological network of unmanned electric vehicles.Based on the original OFDM carrier bandwidth,F-OFDM is adopted to divide several sub-bands with different parameters and filter the sub-bands.The rapid mobility of the 5G+V2X eco-network and the dense traffic of the next generation of driverless electric vehicle networks drive the development of driverless electric vehicles based on URLLC for ultra-reliable and low-latency data interaction services.
