Challenges and Key Progress in Next Generation Multiple Access Technology
The next generation of multiple access technology will break through the design principles based on orthogonality,and achieve higher spectral and energy efficiency through non-orthogonality design and more advanced information processing technologies.In re-sponse to the different challenges faced by massive random access and non-orthogonal multiple access(NOMA),it is believed that differ-ent access methods and receiver designs can significantly improve the efficiency of large-scale access and data transmission.In addition,the flourishing development of technologies such as artificial intelligence,massive multiple input multiple output(MIMO),and multi-cell co-operation has also provided new possibilities for the development of next-generation multiple access technology.
