摘要
自20世纪80年代以来,移动通信已彻底改变世界,对人们的生活产生了深远影响.在5G成功商用的今天,人们又开始思考6G会是什么样子.作为下一代移动通信系统,6G不仅在频谱效率、时延、可靠性等通信KPI指标上提出了更高的要求,其内涵也将涉及人工智能、感知等新元素,远超传统意义上移动通信的范畴.为了实现6G愿景,迫切需要业界研究与之相适应的先进无线技术方案.本文重点介绍了 6G无线空口多个研究方向的技术趋势和进展,包括信道编码技术、多址和波形技术、智能超表面技术、智能MIMO(multiple input multiple output)技术等,提出并初步验证了一系列创新技术点,如便车码、格码多址等.这些创新技术的提出,对6G愿景和KPI指标的实现起到有力的支撑作用.
Abstract
Since the 1980s,mobile communication has thoroughly transformed the world,profoundly impacting the daily lives of humans.With the successful commercialization of 5G,people are now pondering what 6G will be.As the next generation of mobile communication systems,6G not only imposes higher requirements on communication KPI such as spectrum efficiency,latency,and reliability but also involves new elements,such as artificial intelligence and sensing,far beyond the scope of traditional mobile communication.In order to realize the vision of 6G,there is an urgent need for the industry to research advanced wireless technology solutions that are compatible with these new technologies.This paper focuses on the technical trends and progress of several research directions in the 6G wireless air interface,including channel coding technology,multiple access and waveform technology,intelligent metasurface technology,intelligent MIMO technology,etc.Moreover,we propose and preliminarily verify a series of innovative technical points,such as free-ride codes and multiple access based on lattice code.The proposal of these innovative technologies provides strong support for the realization of the vision and KPI of 6G.
