Abstract

In a 5G wireless communication system, demands of massive connectivity, ultra-low latency, higher data rates, higher reliability, and many more are fulfilled by NOMA (non-orthogonal multiple access) which is one of the potential candidates that can carry multiple users at the same time and frequency. As NOMA uses the power allocation method to transmit signals, a problem of mismatch between quality of service (QoS) and channel conditions of the users occurs. To resolve this issue, a scheme cooperative rate-splitting non-orthogonal multiple access (C-RS-NOMA) has been proposed in this work to enhance the performance of downlink power-domain NOMA in terms of outage probability, system capacity, spectrum efficiency, and energy efficiency. The performance of the proposed techniques has also been compared with the existing cooperative-NOMA and traditional NOMA techniques. The simulation results showed the improvement in different key parameters of C-RS-NOMA with respect to the existing NOMA and cooperative NOMA schemes.
