Due to the ability to control the propagation environment, introducing intelligent reflective surfaces (IRS) into a multi-user network can reduce costs, signal processing complexity, and energy consumption. In this work, a comprehensive downlink framework for a blind-IRS-supported CNOMA system is established to enhance outage performance for both cell-edge and near users. The closed-form analytical expressions for the outage probability of the near and cell-edge users within this proposed system are derived. Furthermore, these analytical expressions are validated through Monte-Carlo simulations. The cell-edge user of our proposed model outperforms traditional NOMA and IRS-assisted NOMA variants. To achieve a target outage probability of 10-3, our proposed system requires ? 4 dB lower signal-to-noise ratio (SNR) compared to other IRS-assisted NOMA variants. © 2024 IEEE.eninfo:eu-repo/semantics/closedAccessblind transmissioncell-edge userscooperative non-orthogonal multiple access (CNOMA)intelligent reflective surfaces (IRS)outage probabilitysixth-generation (6G)Conference ObjectN/A
