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 $3^{\mathrm {rd}}$ Generation Partnership Project (3GPP) and present the promising and feasible research directions toward this challenging topic for the realization of 5G and beyond network.
Highlights
In future wireless communication, it is expected that hundreds of different devices and users communicate with each other simultaneously
This article investigates and highlights the issues of interferences observed in different structures and techniques of the current 5G network, in which we mainly focus on Heterogeneous Network (HetNet), RN, D2D, and IoT to gain new insights into designing efficient 5G and beyond as well as 6G networks in the near future
For next-generation communication, it is expected that billions of devices communicating with each other require higher throughput while maintaining the spectrum frequency and Quality of Services (QoS) for each user
Summary
It is expected that hundreds of different devices and users communicate with each. Researchers from all parts of the communication and networking societies, from academia to industrialists and vendors to operators, have actively participated in making this theme possible [2] This phenomenon leads to enormous growth in higher throughput, larger capacity, and lower latency in the air (up to 1ms) and in a cellular network (end-to-end delay less than 10ms) [3]. Technological enhancement in the traditional single-cell network due to several limitations is impracticable This phenomenon leads to innovative design and wireless communication techniques that help accomplish user’s requirements in the decade. In a multi-tier 5G cellular network, the simultaneous operation of many small cells is severely damaged by the different types of interferences that limit the user’s quality of experience and reduce the current.
