N2 - This paper proposes a resource allocation method that considers the desired user traffic volume as well as the channel conditions for a hybrid multiple access scheme employing both non-orthogonal multiple access (NOMA) and orthogonal multiple access (OMA). In the proposed approach, using both NOMA and OMA in the same bandwidth, a resource pattern combined with different user requirements is introduced to effectively meet the demand of diversified wireless services for beyond 5G. Further, the actual throughput of each combination is calculated, and the combination that effectively achieves the highest throughput is determined as the best resource pattern. Finally, the effectiveness of the proposed scheme is demonstrated in comparison with NOMA alone, OMA alone, and the conventional hybrid scheme that does not consider user requests under diversified user traffic for enhanced mobile broadband (eMBB) and ultra-reliable and low-latency communication (URLLC) through computer simulations.
