“…In dense mmWave networks, a study has been conducted to avoid inter-BS interference by choosing a downstream transmission coordination scheme and decision made on the schedule of packet delivery based on SINR level [218]. Few authors discussed the inter-BS beam coordination process to increase the network capacity by providing coordination algorithms among the several BSs [219]. In contrast, spectrum pooling has been investigated by using a centralized beam coordination technique [220].…”

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.

“…The backhaul throughput provided by the network differs depending on the density of gateway access points predicted in [3] can thus be realized using wireless mesh backhauling, as long as the backhaul link data rates are high enough. For 10X increase in access point density, LTE cells with cell traffic in the order of hundreds of Mbps (or 1 Gbps with carrier aggregation) can be supported using wireless links with data rate of several Gbps, which is possible using the unlicensed 60 GHz band.…”

“…LTE data rates are projected to approach Gigabits per second peak rates through carrier aggregation, which is likely to be extended further in next generation networks by using 60 GHz -or other unlicensed millimeter (mm) wave bands -directly from pico base station to the mobile [2], assuming that significant challenges due to blockage and mobility can be overcome. Indeed, a recent interference analysis for such networks [3] indicates that capacities of the order of terabits per second per kilometer (along a single urban canyon) can be obtained with only a few GHz of spectrum by taking advantage of the aggressive spatial reuse enabled by highly directional mm wave links. Moreover, this capacity roughly adds up across parallel canyons, given the strong isolation provided by building blockage.…”

Picocellular architectures are essential for providing the spatial reuse required to satisfy the everincreasing demand for mobile data. A key deployment challenge is to provide backhaul connections with sufficiently high data rate. Providing wired support (e.g., using optical fiber) to pico base stations deployed opportunistically on lampposts and rooftops is impractical, hence wireless backhaul becomes an attractive approach. A multihop mesh network comprised of directional millimeter wave links is considered here for this purpose. The backhaul design problem is formulated as one of joint routing and resource allocation, accounting for mutual interference across simultaneously active links. A computationally tractable formulation is developed by leveraging the localized nature of interference and the provable existence of a sparse optimal allocation. Numerical results are provided for millimeter (mm) wave mesh networks, which are well suited for scaling backhaul data rates due to abundance of spectrum, and the ability to form highly directional, electronically steerable beams.

“…While the system design concepts presented here are of rather general applicability, our numerical results are for a particular setting that we feel has great promise, as also discussed in some of our prior publications [5,9,10,18]. We propose to employ the 60 GHz unlicensed band for base station to mobile communication in outdoor picocells: More specifically, we consider picocellular base stations deployed on lampposts on each side of the street along an urban canyon (e.g.…”

Millimeter (mm) wave picocellular networks are a promising approach for delivering the 1000-fold capacity increase required to keep up with projected demand for wireless data: the available bandwidth is orders of magnitude larger than that in existing cellular systems, and the small carrier wavelength enables the realization of highly directive antenna arrays in compact form factor, thus drastically increasing spatial reuse. In this paper, we carry out an interference analysis for mmwave picocells in an urban canyon with a dense deployment of base stations. Each base station sector can serve multiple simultaneous users, which implies that both intra-and intercell interference must be managed. We propose a cross-layer approach to interference management based on (i) suppressing interference at the physical layer and (ii) managing the residual interference at the medium access control layer. We provide an estimate of network capacity, and establish that 1000-fold increase relative to conventional LTE cellular networks is indeed feasible.
