矿用5G是智能矿山建设的基础,为满足智能矿山多样化的应用需求,需要依托5G通信演进技术推动矿用5G通信演进系统的实现。梳理了矿用5G技术研究及系统部署现状:矿用5G初步实现了音视频通话、高清视频分析、装备远程控制等应用,但存在终端形态单一、上行链路负荷较重、5G通信系统与定位系统分立建设等问题。分析了3GPP Release 17的5G通信演进技术在矿用5G通信中的适用性,指出RedCap轻量化终端技术、NR直连通信技术、NR定位技术将成为矿用5G通信演进的关键技术。研究了矿用5G通信演进关键技术:RedCap轻量化终端技术能够满足矿用无线传感器、单路无线传输的矿用视频监控设备、智能矿灯、智能穿戴设备的低功耗、低成本的多模态终端研发需求;NR直连通信技术应用于矿井自动驾驶车载终端与巷侧设备、应急通信中继设备,可满足矿井自动驾驶和应急通信的低时延、高可靠传输需求;NR定位技术应用于矿井通信定位一体化,可满足矿井通信定位系统融合的技术需求。提出了矿用5G通信演进系统架构,为建设矿用5G全连接矿井、支持多链路无线接入、实现通信感知一体化提供了方向。
The mine 5G is the foundation of intelligent mine construction.In order to meet the diversified application requirements of intelligent mine,it is necessary to promote the realization of mine 5G-advanced communication evolution system through 5G-advanced communication evolution technology.The current status of mine 5G technology research and system deployment is reviewed.The mine 5G has preliminarily realized audio and video call,HD video analysis,equipment remote control and other applications.However,there are some problems such as single terminal form,heavy uplink load,separate construction of 5G-advanced communication system and positioning system,etc.This paper analyzes the applicability of 5G-advanced communication evolution technology of 3GPP Release 17 in mine 5G-advanced communication.It is pointed out that RedCap lightweight terminal technology,NR direct connection communication technology and NR positioning technology will become the key technologies of mine 5G communication evolution.The key technologies of mine 5G-advanced communication evolution are studied. RedCap lightweight terminal technology can meet the research and development requirements of low-power consumption and low-cost multimode terminals of mine wireless sensors, single-channel wireless transmission mine video monitoring equipment, intelligent miner lamps and intelligent wearable devices. NR direct connection communication technology is applied to mine automatic driving vehicle-mounted terminal, roadway side equipment and emergency communication relay equipment. It can meet the requirements of low delay and high reliable transmission of mine automatic driving and emergency communication. NR positioning technology is applied to mine communication and positioning integration to meet the technical requirements of mine communication and positioning system fusion. This paper puts forward the architecture of mine 5G-advanced communication evolution system. The study provides the direction for building 5G fully connected mine, supporting multi-link wireless access and realizing the integration of communication and perception.
