摘要
6G大规模通信场景迫切需要使用新型多址技术解决海量终端随机接入问题,其他多种场景也需要6G新型多址来提高传输速率,降低接入时延,增强传输可靠性.回顾了5G非正交多址的标准化历程,总结了各种非正交多址技术的特点,以及在标准化过程中的经验,研究并评估了稀疏交织多址和基于Reed-Muller码的无源多址两种新型多址性能.本研究可为未来6G新型多址的选型和标准化提供有益参考.
Abstract
The 6G massive machine type communication urgently requires new multiple access technology to support random access of mas-sive machine type terminals,and other scenarios in 6G systems also need new multiple access to increase the data rate,reduce transmis-sion delay and enhance transmission reliability.The standardization process of 5G non-orthogonal multiple access and the properties of vari-ous non-orthogonal multiple access techniques are reviewed.The experience in the standardization process is then introduced.The perfor-mance of two new types of multiple access is studied,including sparse interleave division multiple access and unsourced multiple access based on Reed-Muller code.This study can provide useful references for the scheme selection and the standardization of the 6G multiple access technology in the future.
