摘要
随着5G部署规模的扩大,产业界对5G演进的关注度持续提升。5G演进既是现有5G技术的进一步发展,也是5G向6G的过渡。2021年4月,3GPP将5G演进命名为“5G-Advanced”。介绍了5G演进的节奏,归纳了5G技术发展至今的状态,展望了5G演进的方向,提出了以“融合”“智慧”“低碳”3个特征为代表的5G演进趋势。重点介绍了多媒体增强、异构网络融合、网络大数据分析等5G演进方向。结合网络技术的发展,指出了5G演进过程中系统设计的重点和难点。
With the expansion of 5G deployment scale,the industry has paid more attention to 5G evolution.It is not only the extension of the existing 5G technology,but also a transition from 5G to 6G.In April 2021,3GPP named 5G evolution as 5G-Advanced.The process of 5G-Advanced was introduced.The status of 5G technology so far was summarized,and the direction of 5G evolution technologies were analyzed.Converged,intelligent and low-carbon as the three characteristics of the 5G evolution was proposed.More specially,the multimedia enhancement,heteroge-neous network convergence and network big data analysis were introduced.Considering the network technology de-velopment,difficulties and key aspects of the system design were also identified.
