摘要

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。

Abstract

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.
