Non-orthogonal multiple access (NOMA) allows users sharing a resource-block to efficiently reuse spectrum and improve cell sum rate <inline-formula> <tex-math notation="LaTeX">$\mathcal {R}_{\mathrm{ tot}}$ </tex-math></inline-formula> at the expense of increased interference. Orthogonal multiple access (OMA), on the other hand, guarantees higher coverage. We introduce partial-NOMA in a large two-user downlink network to provide both throughput and reliability. The associated partial overlap…

Energy Efficiency Maximization in the Uplink Delta-OMA Networks
• Computer Science, Engineering
IEEE Transactions on Vehicular Technology
• 2021
A multi-objective optimization framework to maximize the uplink energy efficiency in a multi-cell network enabled by D-OMA is developed and numerical results show that D- OMA outperforms the conventional non-orthogonal multiple access (NOMA) and orthogonal frequency divisionmultiple access (OFDMA) when the adjacent sub-channel overlap and scheduling is optimized jointly.

P-NOMA partially overlaps the UEs’ signals by controlling the extent of the overlap and can thus reduce the interference from other UEs and achieves performance that is better than that of conventional NOMA with respect to the sum of the achievable rate.

A novel 3GPP-inspired user ranking technique is developed to construct a user cluster for the non-orthogonal transmission by grouping users from the cell center (CC) and cell edge (CE) regions, which allows the pairing of users with distinct link qualities, which is imperative for harnessing NOMA performance gains.
