6G发展趋势与候选关键技术分析

6G Network Evolution and Key Candidate Technologies

为适应未来垂直行业和用户对无线网络的多维度需求,6G需要在5G的基础上对多项技术性能指标实现量级提升。为达到6G预期的关键性能指标,需要从网络架构、空口传输、安全与智能等多层面进一步发展5G技术,推动向6G关键技术的平滑演进。文章首先对6G愿景与发展现状进行梳理,介绍6G关键性能指标需求,然后,对6G使能技术进行分析,遴选6G在网络架构、空口传输、网络安全和智慧内生等方面的潜在使能技术。这些使能技术将为实现6G愿景提供有力的支撑。

Compared with the current 5G network,6G will achieve an order of magnitude improvement in system performance indicators,and will bring many new features to meet the multi-dimensional needs of future vertical industries and users for nextgeneration wireless networks.To achieve the expected key performance indicators(KPIs)of 6G,5G technology will be further developed in various areas such as network architecture,air-interface transmission,security and intelligence,to promote the smooth evolution of key technologies to 6G.In this paper,we first summarize the 6G vision,development status,and the requirements of 6G KPIs.Then,we analyze 6G enabling technologies,select and introduce potential 6G enabling technologies in terms of network architecture,air-interface transmission,network security,and endogenous intelligence.The enabling technologies will strongly support the realization of the 6G vision.
