To elaborate on IRM (Interference Resource Management) issues in a multi-connection environment with emphasis on 5G component carrier management, this paper evaluates system-level simulation approaches. Additionally, it assesses the requirements for ultra-high connection density of IoT devices in mMTC (massive Machine-Type Communications) environments. The research into the proposed solutions has resulted in various publications, conference papers, journals, books, and standards such as ITU for a study regarding the evaluation of 5G. Specifically, this paper presents an in-depth analysis of solutions for better management of networks and services based on intelligent algorithms and techniques in heterogeneous broadband environments of 5th and subsequent generations. This takes into account the current situation and new challenges of networks, focusing on optimizing connectivity and managing the complexity introduced by high-density scenarios typical of 5G deployments. The study integrates advanced modeling and simulation techniques to foresee network behavior under different configurations and usage patterns, aiming to enhance overall efficiency and user experience in 5G networks.
