摘要

在6G物联网时代，海量终端设备智慧互联，发掘环境信息提高生活质量，创造更加智能的世界。随着经济社会和工业的发展，工业物联网（industrial internet of things，IIoT）中工业节点的数量以惊人的速度增长，这些工业节点间实时传输交换信息，对通信的时延和可靠性提出了更高要求。在有限的时频资源和严格的通信质量要求下，为保证IIoT中海量终端的超可靠超低时延通信（ultra-reliable and low-latency communication，URLLC），需要从低时延、可靠性、能量效率、频谱效率和可拓展性等方面对存在的关键问题进行分析。在工业物联网场景下，结合URLLC的特点和需求，研究了工业物联网中通信的关键问题：活跃用户检测、随机接入、资源分配和通算融合中的挑战和机遇，对关键问题以及现有技术进行总结分析后，提出了未来的研究方向。

Abstract

In the age of 6G internet of things

massive terminal devices are connected intelligently to explore environmental information to improve life quality and create a more intelligent world.With the development of economic society and industry

the number of industrial nodes in the industrial internet of things (IIoT) grows at an significant speed.The real-time transmission and exchange of information between these industrial nodes puts forward higher requirements for communication delay and reliability.Under limited time-frequency resources and strict communication quality requirements

in order to ensure ultra-reliable and low-latency communication (URLLC) of massive terminals in IIoT

it is necessary to analyze the existing key problems from the aspects of low delay

reliability

energy efficiency

spectrum efficiency and scalability.In the scenario of IIoT

combined with the characteristics and requirements of URLLC

the key issues of communication in IIoT were studied

including challenges and opportunities in active user detection

random access

resource allocation and convergence of communication and computation.After summarizing and analyzing the key issues and existing technologies

the future research direction was proposed.
