英文摘要: Abstract(#br)This letter proposes a novel downlink hybrid multiple access (HMA) scheme based on non-orthogonal multiple access (NOMA) and orthogonal multiple access (OMA) for the fifth generation (5G) networks. A necessary condition on the users' channel gains under which HMA can outperform pure NOMA or OMA is derived. Furthermore, an optimization problem is formulated and solved numerically to obtain optimal groups size resulting in optimal throughput. The exact closed-form expression for the outage probability is also derived. Numerical results are presented to compare the average outage and throughput performance of HMA with conventional NOMA and OMA. In addition, the impact of varying OMA group size on throughput is also presented.
