Abstract

In order to solve the problem of spectrum waste in the LTE-Railway (LTE-R) system, the paper uses Cognitive Radio (CR) to improve the ability of spectrum sharing on Vehicle-to- Ground communication. By constructing a novel Cognitive Radio Network (CRN) in LTE-R system, the Cognitive LTE-R eNodeB (C-eNodeB) can work with Vehicle Gateway (VG) and allocate idle and wasted spectrum resources to the passengers communicating devices to improve spectrum utilization of LTE-R, without impacting train-ground communication. Aiming at the novel CRN architecture, a C-eNodeB Queue Management Strategy (QMS) based on Type of Service (ToS) value priority is proposed to reduce the Real-Time (RT) service delay of Secondary Users (SU) caused by FIFO QMS. The simulation results show that the proposed CRN effectively improves the spectrum utilization of LTE-R system and the C-eNodeB QMS based on the ToS value priority significantly reduce the delay of RT business of passengers.
认知无线电:LTE-R系统中实现频谱共享的一种方法
为了解决LTE-Railway (LTE-R)系统频谱浪费问题,本文采用认知无线电(CR)技术提高车地通信频谱共享能力。通过在LTE-R系统中构建一种新型的认知无线网络(CRN),认知LTE-R eNodeB (C-eNodeB)可以与车辆网关(VG)协同工作,将空闲和浪费的频谱资源分配给乘客通信设备,在不影响列车-地面通信的情况下提高LTE-R的频谱利用率。针对新型CRN体系结构,提出了一种基于服务类型(ToS)值优先级的C-eNodeB队列管理策略(QMS),以减少FIFO队列管理导致的二次用户实时(RT)业务延迟。仿真结果表明,提出的CRN有效提高了LTE-R系统的频谱利用率,基于ToS值优先级的C-eNodeB QMS显著降低了乘客RT业务的延迟。
