Abstract

In the landscape of 5G networks, efficient resource allocation (RA) stands as a critical factor in meeting the diverse demands of applications and users. This paper delves into optimizing RA within 5G Multiple Input Multiple Output (MIMO) networks by leveraging Downlink/Uplink Decoupling (DUDe) techniques. MIMO technology, enabling the simultaneous transmission of multiple data streams, holds promise for boosting spectral efficiency. However, accommodating the dynamic and diverse user requirements poses a significant challenge in resource allocation. By employing advanced DUDe techniques, this study dynamically allocates resources in 5G MIMO Heterogeneous Networks (HetNets), seeking to enhance throughput, minimize latency, and optimize user satisfaction. The paper includes scenarios involving varying User Equipment (UE) densities and mobility to evaluate system performance under different load conditions. Through simulation-based analysis, this paper highlights the efficacy of the proposed approach in significantly improving network performance, energy efficiency, and resource utilization.
