Interference Management in 5G and Beyond Network: Requirements, Challenges and Future Directions

Abstract

In the modern technological world, wireless communication has taken a massive leap from the conventional communication system to a new radio communication network. The novel concept of Fifth Generation (5G) cellular networks brings a combination of a diversified set of devices and machines with great improvement in a unique way compared to previous technologies. To broaden the user's experience, 5G technology provides the opportunity to meet the people's potential necessities for efficient communication. Specifically, researchers have designed a network of small cells with unfamiliar technologies that have never been introduced before. The new network design is an amalgamation of various schemes such as Heterogeneous Network (HetNet), Device-to-Device (D2D) communication, Internet of Things (IoT), Relay Node (RN), Beamforming, Massive Multiple Input Multiple Output (M-MIMO), millimeter-wave (mm-wave), and so on. Also, enhancement in predecessor's techniques is required so that new radio is compatible with a traditional network. However, the disparate technological models' design and concurrent practice have created an unacceptable intervention in each other's signals. These vulnerable interferences have significantly degraded the overall network performance. This review article scrutinizes the issues of interferences observed and studied in different structures and techniques of the 5G and beyond network. The study focuses on the various interference effect in HetNet, RN, D2D, and IoT. Furthermore, as an in-depth literature review, we discuss various types of interferences related to each method by studying the state-of-the-art relevant research in the literature. To provide new insight into interference issue management for the next-generation network, we address and explore various relevant topics in each section that help make the system more robust. Overall, this review article's goal is to guide all the stakeholders, including students, operators, engineers, and researchers, aiming to explore this promising research theme, comprehend interferences and their types, and related techniques to mitigate them. We also state methodologies proposed by the 3 rd Generation Partnership Project (3GPP) and present the promising and feasible research directions toward this challenging topic for the realization of 5G and beyond network.

Predistortion-Based Linearization for 5G and Beyond Millimeter-Wave Transceiver Systems: A Comprehensive Survey

“…d) Interference Management: Insufficient robustness to the interference has always been a symptomatic issue for microwave-based and MMW communications. From the 5G cellular BS point of view, it is an example of multi-tier (or cross-tier) interference from the SBS to MBS, which has been largely elucidated in recent research works [15], [252]. Ultimately, the variable load conditions due to unstable PA interconnections are the main source of electromagnetic interference regardless of the small-scale or large-scale networks.…”

“…where F ∈ B Nu×Nf denotes the binary subcarrier allocation matrix and its elements are defined according to (5). P = [P 1 , .…”

“…In this context, efficient interference mitigation mechanisms, such as user association, radio resource management and interference alignment, should be designed and utilized in the networks [4]. Diverse interference management techniques have been proposed for HetNets which require coordination among network tiers to optimally design the transmission parameters and resources [1], [5]. For vHetNets, the challenge of interference gets more complicated and challenging, and urges for more novel techniques to deal with it.…”
