“…A wide range of services will be available for each scenario, including HD-TV, online gaming, virtual reality, augmented reality, live video streaming, video conferencing, cloud storage, high-definition image upload/download, intelligent home control, etc. [114,115]. UDN's fundamental structure is defined in terms of SC or density of the access point, where the number of serving access points (AP) is equal to or more than the users' number [116].…”

Beyond Fifth Generation (B5G) networks are expected to be the most efficient cellular wireless networks with greater capacity, lower latency, and higher speed than the current networks. Key enabling technologies, such as millimeter-wave (mm-wave), beamforming, Massive Multiple-Input Multiple-Output (M-MIMO), Device-to-Device (D2D), Relay Node (RN), and Heterogeneous Networks (HetNets) are essential to enable the new network to keep growing. In the forthcoming wireless networks with massive random deployment, frequency re-use strategies and multiple low power nodes, severe interference issues will impact the system. Consequently, interference management represents the main challenge for future wireless networks, commonly referred to as B5G. This paper provides an overview of the interference issues relating to the B5G networks from the perspective of HetNets, D2D, Ultra-Dense Networks (UDNs), and Unmanned Aerial Vehicles (UAVs). Furthermore, the existing interference mitigation techniques are discussed by reviewing the latest relevant studies with a focus on their methods, advantages, limitations, and future directions. Moreover, the open issues and future directions to reduce the effects of interference are also presented. The findings of this work can act as a guide to better understand the current and developing methodologies to mitigate the interference issues in B5G networks.

“…Overhead signaling is required for cell coordination. The coordination of interference is a sophisticated challenge in UDNs because of the varying BS density, which causes dominant interference in some BSs [115]. As a result, joint IM and handover among different networks while taking into consideration SE and EE require more research.…”

“…In this context, [3] and [4] are some of the first papers to attempt to address the fundamental issues relating to the deploying of UDNs and demonstrating the utility of UDNs in 5G wireless networks, such as establishing what density of infrastructure is needed to cope with specified traffic loads and what benefits accrue from network-wise coordination. Generally, many of the papers focus on the compilation of a list of recent achievements, research findings, potential challenges and enabling technologies in the context of UDNs [5][6][7][8][9][10][11]. Additionally, [12,13] present a comprehensive survey of security issues in UDNs, focusing on physical layer security issues and security-based resource management.…”

Ultra-Dense Networks: Taxonomy and Key Performance Indicators

One major influence on the future deployment of cellular networks will be a continuous increase in traffic inside mobile broadband systems. Moreover, traditional macrocell-based mobile communication networks will struggle to keep up with the enormous expansion in the demand for communications services in the future. Densification of networks is required if we are to meet the comprehensive needs for end terminals for a wide range of applications. One of the leading concepts in this competitive environment is the Ultra-Dense Network (UDN) where the access nodes and/or the communication links per unit area are densified, with the aim of improving overall network performance. The location of the UDN nodes meets the criteria for symmetry with a high probability. Ultra-dense cell deployment aims to reduce the physical distance between the transmitter and receiver in order to boost system performance and generally optimize the values of a wide variety of key performance indicators (KPIs). This paper aims to provide a taxonomy of UDNs and specifically of UDN-related KPIs. Initially, we address the complex questions “What is the current understanding of what ultra-dense networks are and what they should be, and how can we measure their performance?” by shedding light on the fundamental characteristics of UDNs.
