随着5G与行业的进一步融合,目前标准所定义的Release 15/Release 16/Release 17能力在行业需求的支持上略显不足。结合行业关注的重点特性与能力,详细回顾了5G-Advanced(Release 18)的技术演进方向,并给出该技术演进方向潜在的技术方案与解决思路,为后续的技术演进提供参考,包括下行MIMO增强、上行传输增强、移动性增强、拓扑传输技术增强、Sidelink 增强、RedCap 技术演进、定位能力扩展与增强和AI/ML 5G等;同时,详细分析了当前行业现场网存在的问题,包括行业终端接入、接入网络、E2E QoS保障等多个层面,提出了包括基于SLA的行业组网技术、高带外(OOB)抑制技术、多缓存调度(MBS)技术、全连接行业接入网络技术、算力网络(CFN)技术,并给出了其潜在的实现方式。
With the further integration of 5G and the industry
the current standard-defined Release 15/Release 16/Release 17 capabilities were slightly insufficient to support industry needs.The technological evolution direction of 5G-Advanced (Release 18) was reviewed in detail
and potential technical solutions for the technological evolution were given
including downlink MIMO enhancement
uplink transmission enhancement
mobility enhancement
topology transmission technology enhancement
Sidelink enhancement
RedCap technology evolution
positioning capability expansion and enhancement
AI/ML 5G
etc.At the same time
the current industry scene was analyzed in detail
those existing problems including industry terminal access
access network
E2E QoS guarantee
etc.The 5G technologies including SLA-based industry networking
high out-of-band (OOB) suppression
multi-buffer scheduling (MBS)
fully connected industry access network technology
computing force network (CFN) technology
and potential implementation methods were proposed.
