This paper proposes a hybrid non-orthogonal multiple access (NOMA) assisted downlink transmission scheme for both single-input single-output (SISO) and multiple-input single-output (MISO) systems. For the SISO scenario, a novel hybrid NOMA scheme is introduced, where NOMA is implemented as an add-on of a legacy time division multiple access (TDMA) network. The scheme is shown to outperform TDMA in certain conditions, unlike the existing conclusion for uplink hybrid NOMA. For the MISO scenario, the scheme is extended to a network based on both TDMA and space division multiple access (SDMA), where beam sharing is used to ensure compatibility with the legacy network. Near-field communication is considered as an illustrative example to demonstrate the feasibility of hybrid NOMA. Simulation results show that downlink hybrid NOMA outperforms conventional orthogonal multiple access (OMA) in terms of energy efficiency and data rate. The paper also analyzes the properties of the power allocation solutions and shows that downlink hybrid NOMA can achieve a Pareto-optimal solution for the multi-objective energy minimization problem. The results demonstrate that hybrid NOMA can significantly reduce energy consumption compared to OMA, particularly for large data rates. The paper concludes that hybrid NOMA is a promising approach for future wireless networks.This paper proposes a hybrid non-orthogonal multiple access (NOMA) assisted downlink transmission scheme for both single-input single-output (SISO) and multiple-input single-output (MISO) systems.
