论文摘要
对于第五代（5G）无线网络技术，除网络弹性和灵活性外，最重要的设计目标是改进的可靠性和延迟指标，以最好地适应新应用程序的网络操作，例如增强虚拟现实，工业自动化和自动驾驶汽车。这导致了根据超级可靠的低延迟通信（URLLC）进行的设计工作。 2017年12月第三代合伙项目（3GPP）发行版15版集成的技术为URLLC提供了物理层设计的基础。标准化了新功能，例如命理，具有子插入间隔的新传输方案，配置的授予资源等，主要改善延迟方面。 5G版本16中的5G Evolution在2019年12月最终确定的PHY版本可以通过标准化许多新功能来实现改进的延迟和可靠性指标。本文详细概述了5G版本15和发行版16的URLLC功能，描述了这些功能如何允许5G网络中的URLLC操作。
For the fifth generation (5G) wireless network technology, the most important design goals were improved metrics of reliability and latency, in addition to network resilience and flexibility so as to best adapt the network operation for new applications such as augmented virtual reality, industrial automation and autonomous vehicles. That led to design efforts conducted under the subject of ultra-reliable low-latency communication (URLLC). The technologies integrated in Release 15 of the 3rd Generation Partnership Project (3GPP) finalized in December 2017 provided the foundation of physical layer design for URLLC. New features such as numerologies, new transmission schemes with sub-slot interval, configured grant resources, etc., were standardized to improve mainly the latency aspects. 5G evolution in Release 16, PHY version finalized in December 2019, allows achieving improved metrics for latency and reliability by standardizing a number of new features. This article provides a detailed overview of the URLLC features from 5G Release 15 and Release 16, describing how these features permit URLLC operation in 5G networks.
