While traditional methods rely on meta-heuristic optimization techniques such as Whale Optimization Algorithm (WOA), we present an ensemble learning framework that combines multiple advanced algorithms to achieve efficient and practical resource allocation. Our approach decomposes the complex mixed-integer non-linear programming (MINLP) problem into two complementary tasks: Remote Radio Head (RRH) assignment through classification and Physical Resource Block (PRB) allocation through regression. Through extensive experimentation, we demonstrate that our ensemble method achieves 75-78\\% accuracy in RRH assignment with mean squared error of 0.3922 in PRB allocation, while providing near-instantaneous decision-making capabilities after training. The proposed solution offers significant advantages in computational efficiency and scalability compared to traditional optimization approaches, particularly in scenarios requiring real-time resource allocation decisions. Furthermore, we present a comprehensive comparative analysis between our machine learning approach and existing optimization-based methods, highlighting the trade-offs and complementary strengths of each approach. Our findings suggest that machine learning-based resource allocation can serve as a viable alternative or complement to traditional optimization methods in 5G networks.  \nKeywords: 5G Networks, Resource Allocation, Machine Learning, Ensemble Methods, Open Radio Access Networks, Network Optimization  \n1. Introduction  \nThe evolution of mobile communications has reached a pivotal moment with the advent of fifth-generation (5G) networks. This transformation represents not merely an incremental improvement over previous generations but a fundamental reimagining of wireless network architecture and capabilities. The journey from first-generation analog systems to today’s sophisticated 5G networks reflects the exponential growth in  \nboth technological capabilities and user demands, necessitating increasingly complex approaches to network resource management and optimization.  \nEvolution of mobile networks and resource management  \nThe telecommunications landscape has undergone remarkable transformation since the introduction of firstgeneration mobile networks. While 1G networks provided basic voice services through analog transmission, each subsequent generation has introduced revolutionary capabilities. The transition to 2G brought digital voice transmission and basic data services, while 3G enabled mobile broadband and multimedia applications. The fourth generation marked a significant leap forward with all-IP networks and high-speed data services. However, 5G represents an unprecedented advancement in network architecture and service delivery capabilities. Unlike its predecessors, 5G networks are designed with a service-based architecture that supports three distinct categories of services: enhanced Mobile Broadband (eMBB), massive Machine-Type Communications (mMTC), and Ultra-Reliable Low-Latency Communications (URLLC) . This architectural approach fundamentally changes how network resources must be managed and allocated. The introduction of network slicing, virtualization, and software-defined networking creates a more flexible but inherently more complex system for resource allocation.  \nThe advent of Open Radio Access Networks (O-RAN) has further revolutionized network architecture by disaggregating traditional network components. This disaggregation enables unprecedented flexibility in network deployment and management but introduces new challenges in resource coordination and ","cbCaij1YjyE3217s","https://ap.wps.com/l/cbCaij1YjyE3217s","pdf",1152968,1,23,"English","en",105,"# 1.
