<p>This paper examines and analyzes a new design for incremental relaying (IR) with joint transmission of coordinated multipoint non-orthogonal multiple access (JT-CoMP-NOMA) in a network equipped with simultaneous wireless information and power transfer. To analyze the outage characteristics of the incremental relay with the JT-CoMP system, new mathematical formulas are developed to calculate the probability of outages for two users. To validate these formulas, the Monte Carlo approach was also employed. Implementing an incremental relay system within the JT-CoMP network is suggested for a two-user scheme and this IR technique enables the base stations (BSs) to dynamically alternate between a direct non-orthogonal multiple access (NOMA) transmission mode and a cooperative NOMA mode of transmission based on a 1-bit input from the distant user. By analyzing the throughput and outage probability of the suggested system, it has been demonstrated that the optimized structure offers benefits in enhancing both the throughput and outage performance. Adding an IR in the JT-CoMP-NOMA network has been found to decrease the likelihood of system outage and enhance network dependability. It is confirmed that JT-CoMP-NOMA with IR offers a substantial improvement in performance for users located at the cell edge when compared to conventional Cooperative Non-Orthogonal Multiple Access (CCN) and other multiple access schemes.</p>
