论文摘要
超级可信和低延迟通信(URLLC)是第五代(5G)新无线电(NR)技术规格支持的三个主要服务类别之一。在本文中,我们介绍了一个可以满足低延迟和高可靠性要求的物理层体系结构。下行链路系统是根据基于软件定义的无线电(SDR)系统的第三代合作伙伴项目(3GPP)规范设计的。 URLLC系统物理层下行链路在开放源OpenAirInderFace(OAI)平台上实现,以评估该方案的延迟和可靠性性能。不仅基于模拟平台测试了URLLC系统的可靠性性能,而且还通过实现无线系统的实现来评估延迟性能。实验结果表明,设计方案可以大致满足3GPP规范的可靠性和延迟性能要求。
Ultra-reliable and low-latency communication (URLLC) is one of the three major service classes supported by the fifth generation (5G) New Radio (NR) technical specifications. In this paper, we introduce a physical layer architecture that can meet the low-latency and high-reliability requirements. The downlink system is designed according to the Third Generation Partner Project (3GPP) specifications based on software defined radio (SDR) system. The URLLC system physical layer downlink is implemented on the open source OpenAirInterface (OAI) platform to evaluate the latency and reliability performance of the scheme. Not only the URLLC system reliability performance is tested based on the simulation platform, but also the delay performance is evaluated by the realization of the over-the-air system. The experimental results show that the designed scheme can approximately meet the reliability and delay performance requirements of the 3GPP specifications.
