In this work, a hybrid multiple access (HMA) scheme combining H-NOMA and H-OMA is proposed to increase the sum-rate of 5G and beyond networks. By applying HMA strategy in network slicing of eMBB and URLLC, significant gains are achieved compared to standalone MMD-aided H-OMA and H-NOMA schemes.
In this work, we propose a hybrid multiple access (HMA) scheme that combines heterogeneous non-orthogonal multiple access (H-NOMA) with heterogeneous orthogonal multiple access (H-OMA), aiming at increasing the sum-rate of 5G and beyond (B5G) networks. More specifically, the HMA strategy is applied in the network slicing of enhanced mobile broadband (eMBB) and grant-free ultra-reliable low-latency communications (URLLC), two important use cases in the scope of B5G. By considering that the max-matching diversity (MMD) algorithm is used to allocate channels to eMBB users, we show that the proposed HMA scheme can achieve considerable gains when compared to the standalone MMD-aided H-OMA and H-NOMA schemes.
