Issues in Resource Management for 5G Small Cell Deployments

Abstract

The rapid advancement of 5G technology has captured significant attention from academia, industry, and governments worldwide. International standardization bodies such as 3GPP and ITU have formed dedicated working groups to define the standards for the next-generation wireless network, known as 5G. A key innovation of 5G over previous generations lies in its ambitious performance goals, including high peak transmission rates, enhanced spectrum utilization, and improved energy efficiency. One promising approach to meet these performance demands, particularly for stationary or low-velocity users, is the deployment of ultra-dense small cell networks equipped with massive multiple-input multiple-output (MIMO) antennas and multi-user MIMO (MU-MIMO) techniques to enhance spectrum utilization. Additionally, 5G networks need to prioritize energy efficiency, leverage cognitive radio technology for spectrum reuse, support diverse device communication, and use cooperative mechanisms to increase transmission diversity. This study examines a number of resource management issues in 5G small cell networks that are extremely dense.
