Unsourced Multiple Access for 6G Massive Machine Type Communications
文献摘要：
Unsourced multiple access(UMA)is a multi-access technology for massive,low-power,un-coordinated,and unsourced Machine Type Communi-cation(MTC)networks.It ensures transmission re-liability under the premise of high energy efficiency.Based on the analysis of the 6G MTC key perfor-mance indicators(KPIs)and scenario characteristics,this paper summarizes its requirements for radio ac-cess networks.Following this,the existing multiple access models are analyzed under these standards to determine UMA's advantages for 6G MTC according to its design characteristics.The critical technology of UMA is the design of its multiple-access coding scheme.Therefore,the existing UMA coding schemes from different coding paradigms are further summa-rized and compared.In particular,this paper com-prehensively considers the energy efficiency and com-putational complexity of these schemes,studies the changes of the above two indexes with the increase of access scale,and considers the trade-off between the two.It is revealed by the above analysis that some guiding rules of UMA coding design.Finally,the open problems and potentials in this field are given for fu-ture research.
