Abstract: As more and more new mobile multimedia-rich services are becoming available to larger audiences, there is an ever increasing demand for higher data rates as well as larger capacity networks. This demand is to be met under the scope of next-generation mobile communication systems characterized by high speed, large capacity, and good quality-of-service for millions of subscribers. To meet these requirements, a number of energy and spectrally efficient technologies have been proposed for future networks. The sixth-generation (6G) networks need breakthroughs beyond the current 5G. The expected performance targets of 6G are: 1) The connectivity density is ten-fold larger compared to 5G; 2) The peak data rate reaches 1 terabit per second; 3) The energy efficiency is a hundred times higher than that of 5G; 4) The air interface latency decreases to 0.1 millisecond; and 5) The reliability increases to 99.99999%. To this end, highly efficient next generation multiple access (NGMA) techniques are vital for 6G.

Non-orthogonal multiple access (NOMA) has been proposed to overcome the spectral inefficiency of OMA. Specifically, NOMA allows controllable interference via non-orthogonal resource allocation at the expense of a tolerable increase in receiver complexity. The signals transmitted to different users are superimposed into the same time and/or frequency band, and they are recovered with advanced receiver algorithms. Traditional NOMA schemes fail to address the new requirements of 6G. This tutorial will present our solutions about how to evolve the current NOMA to NGMA, which contributes to the Signal Processing for Wireless Communications topic of VTC.
