智能铁路新一代移动通信关键技术探索与展望

移动通信技术的进步驱动着各行各业的产业变革。铁路现有移动通信系统历经几十年的发展,其承载能力越来越难以满足高速增长的现代铁路网建设步伐和智能化发展需求。基于智能铁路应用对移动通信带宽、时延、覆盖等需求和新一代移动通信面临的挑战,开展新一代通信频谱技术、信道编码技术及多功能综合射频技术等新一代移动通信关键技术研究,构建以“车-地、车-车、车-人”信息无缝协同交互为目标的“空天车地一体化”网络,研究并展望通信-导航一体化、通信-计算-存储一体化在智能铁路中的场景应用,提升铁路移动通信服务能力和效率,赋能我国铁路智能化发展。

Exploration and prospect of the key technologies of the new generation mobile communication of intelligent railway

The progress of mobile communication technology drives industrial changes in all walks of life.The carrying capacity of the existing railway mobile communication system is increasingly difficult to meet the rapid growth of modern railway networks even after decades of development.Based on the requirements of intelligent railway applications for mobile communication bandwidth, delay, coverage and other challenges faced by the new generation of mobile communication, the critical technologies of new-generation mobile communication were focused on, such as the new generation of communication spectrum technology, channel coding technology, and multi-functional integrated radio frequency technology.Additionally, an “air-space-vehicle-ground integration” network aiming at seamless collaborative interaction of information among “vehicle-ground, vehicle-vehicle, and vehicle-person” was constructed.Furthermore, the application of communication-navigation integration, and communication-computing- storage integration were studied and prospected in intelligent railways.It will play a vital role in improving the service capability and efficiency of railway mobile communication and enable the development of China’s railway intelligence.
