“…Its features includes: low computational complexity, easy implementation, optimal solution attainment and suitability for large-size network. Stochastic geometry is the mathematical tool used in [177] to analyse the heterogeneous structure of emerging wireless networks in FD communication. In [178] and [179], the tool of stochastic geometry has been applied to ensure EE of BSs and cross-tier interference mitigation respectively.…”

Recently, to address the astonishing capacity requirement of 5G, researchers are investigating the possibility of combining different technologies with ultra-dense networks (UDNs). However, the ultradense deployment of small cells in the coverage area of conventional macrocells known as UDNs introduces new technical challenges such as severe interference, unfairness in radio resource sharing, unnecessary handover, a significant increase in energy consumption, and degraded quality-of-service (QoS). To overcome these challenges and achieve the performance requirements in 5G, there is a need to combine UDNs with other 5G enabling technologies and then, design intelligent management techniques for better performance of the overall networks. Hence, in this paper, we present a comprehensive survey on different generations of wireless networks, 5G new radio (NR) standards, 5G enabling technologies and the importance of combining UDNs with other 5G technologies. Also, we present an extensive overview of the recent advances and research challenges in intelligent management techniques and backhaul solutions in the last five years for the combination of UDNs and other enabling technologies that offers the visions of 5G. We summarise the mathematical tools widely exploited in solving these problems and the performance metrics used to evaluate the intelligent management algorithms. Moreover, we classify various intelligent management algorithms according to the adopted enabling technologies, benefits, challenges addressed, mathematical tools and performance metrics used. Finally, we summarise the open research challenges, provide design guidelines and potential research directions for the development of intelligent management techniques and backhaul solutions for the combination of UDNs and other 5G technologies.

“…To mitigate inter-cell interference in FD ultra-dense small cell networks, a resource split approach was proposed in [17], which classified BS into two groups and allocated half of the resources to each group. The system-level performance of FD MIMO cellular networks was analyzed in [18] while [19] optimized the throughput of a FD wireless network with various transmission strategies. For heterogeneous networks, the interference from cells operating in FD mode was studied in [20], where the throughput of a hybrid FD/HD multi-tier heterogeneous network was derived.…”

“…Applying this assumption to the location of BSs may be inaccurate and inconsistent with the actual scenario, where in practice the locations of BSs are carefully planned. Moreover, inter-cell interference from BSs caused significant performance degradation in UL transmission and it was reported in [18] that sufficient spacing between FD BSs in microcells is necessary to make UL transmission feasible. Therefore, in this paper, we adopt a more general and realistic scenario where BSs are distributed according to a Martérn Hard-core point process (HCPP) [21].…”

We analyze the performance of a cellular network, where Poisson point process distributed half-duplex (HD) downlink (DL) and uplink (UL) users are served by multiple full-duplex (FD) base stations (BSs). To address the surge in interference in the network due to the simultaneous operation in time and frequency of the FD BSs, we (a) adopt a self-interference cancellation scheme at each BS, and (b) apply linear interference alignment in each cell to cancel the intra-cell interference. Further, to better capture the distribution of the FD BSs, we model the BSs as a Matérn hard-core point process, in which a minimum distance is imposed between points. The performance of both UL and DL users is analyzed by deriving general expressions and closed-form approximations for the outage probability and throughput. Next, simulations are carried out for both macro and micro cell environments under both FD and HD operations with respect to various network parameters. Our results reveal several fundamental characteristics and the necessary conditions required for the successful deployment of such networks.INDEX TERMS Full-duplex communication, interference alignment, Matérn hard-core point process, stochastic geometry.

“…The studies that offer a clearer perception of the FD performance in the interference limited multi-cell network environment generally use mathematical frameworks based on stochastic geometry [6], [7], [8] and convex-optimization [9], [10], [11], [12], [13], [14]. Stochastic geometry is a mathematical tool used in modeling and analysing the performance of large dense wireless networks with random topologies.…”

“…The multiple antennas are essentialy used for signal-to-interference-noise ratio (SINR) maximization, via MRC technique; this brings larger SE gains than using them for supressing the inter-cell CCI via the ZF method. An investigation on whether to deploy FD tranceivers on macro-or micro-cells networks in an interference-limited multi-user scenario is conducted in [8] under the assumption that SI is sufficiently cancelled. Results show that without proper countermeasures for CCI management, the FD communication is infeasible on the macro-cell network.…”

Theoretically, full-duplex (FD) communications can double the spectral-efficiency (SE) of a wireless link if the problem of self-interference (SI) is completely eliminated. Recent developments towards SI cancellation techniques have allowed to realize the FD communications on low-power transceivers, such as small-cell (SC) base stations. Consequently, the FD technology is being considered as a key enabler of 5G and beyond networks. In the context of 5G, FD communications have been initially investigated in a single SC and then into multiple SC environments. Due to FD operations, a single SC faces residual SI and intra-cell co-channel interference (CCI), whereas multiple SCs face additional inter-cell CCI, which grows with the number of neighboring cells. The surge of interference in the multi-cell environment poses the question of the feasibility of FD communications. In this article, we first review the FD communications in single and multiple SC environments and then provide the stateof-the-art for the CCI mitigation techniques, as well as FD feasibility studies in a multi-cell environment. Further, through numerical simulations, the SE performance gain of the FD communications in ultra-dense massive multipleinput multiple-output enabled millimeter wave SCs is presented. Finally, potential open research challenges of multi-cell FD communications are highlighted.
