## 5 Conclusions  
In this study, we took into account NOMA interoperability with MEC. We summarized the significant aspects and technologies used by the many publications featured in the survey and gave a comprehensive overview of NOMA-enabled MEC. Furthermore, we pinpoint important unresolved issues and the accompanying directions for further investigation. The combination of NOMA and MEC will be a game-changer as we approach the generation of future 6G and B6G technologies, offering a potent approach that can influence 6G and B6G's performance characteristics, including latency, connection density, data rate, energy efficiency, and mobility. In the future, we intend to provide solutions to the resolved issues presented.
