“…The ultra-densification of networks that is currently envisioned for 5G will bring new challenges to the radio access, especially related to interference management. In fact, ultra-dense networks are characterized by interference patterns that change quickly in time and that strongly depend on the realistic network deployment [16]. Therefore, interference mitigation techniques must be sufficiently dynamic and operate on a sufficiently small time-scale to ensure that the fluctuations in the interference are captured.…”

Heterogeneous networks constitute a promising solution to the emerging challenges of 5G networks. According to the specific network architecture, a macro-cell base station (MBS) shares the same spectral resources with a number of small cell base stations (SBSs), resulting in increased co-channel interference (CCI). The efficient management of CCI has been studied extensively in the literature and various dynamic channel assignment (DCA) schemes have been proposed. However, the majority of these schemes consider a uniform approach for the users without taking into account the different quality requirements of each application. In this work, we propose an algorithm for enabling dynamic channel assignment in the 5G era that receives information about the interference and QoS levels and dynamically assigns the best channel. This algorithm is compared to state-of-the-art channel assignment algorithm. Results show an increase of performance, e.g., in terms of throughput and air interface latency. Finally, potential challenges and way forward are also discussed.

“…There have already been tremendous consideration on network densification toward 5G networks. A rich amount of researches have addressed many issues of dense HetNets, for example, a general overview on dense HetNets [38], the role of small cells [39], performances of dense HetNets from various deployment perspectives [40], coordination of interferences in dense HetNets [41], cooperative distributed radio resource management in hyper-dense HetNets [42], energy efficiency, spectral efficiency and QoS trade-off [43], coverage analysis of LTE urban HetNets with dense femtocells [44], and a novel architecture using small cells to address MTC traffic [45]. In dense HetNets, an extremely large number of small cells are deployed where the coverages of small cells can even overlap one another.…”

Abstract. In this paper, an extensive review has been carried out on the trends of existing as well as proposed potential enabling technologies that are expected to shape the fifth generation (5G) mobile wireless networks. Based on the classification of the trends, we develop a 5G network architectural evolution framework that comprises three evolutionary directions, namely, (1) radio access network node and performance enabler, (2) network control programming platform, and (3) backhaul network platform and synchronization. In (1), we discuss node classification including low power nodes in emerging machine-type communications, and network capacity enablers, e.g., millimeter wave communications and massive multiple-input multiple-output. In (2), both logically distributed cell/device-centric platforms, and logically centralized conventional/wireless software defined networking control programming approaches are discussed. In (3), backhaul networks and network synchronization are discussed. A comparative analysis for each direction as well as future evolutionary directions and challenges toward 5G networks are discussed. This survey will be helpful for further research exploitations and network operators for a smooth evolution of their existing networks toward 5G networks.

“…Standardized network-based inter-cell interference coordination (ICIC) schemes for LTE range from basic coordination to further enhanced ICIC, and more elaborate coordinated multi-point (CoMP) communication techniques [1][2][3]. The solutions for LTE were mainly designed to offer spectral efficiency benefits for data channel transmissions by applying various forms of intercell coordinated muting (or power adjustments) or interference randomization, while offering only limited benefits for control channel performance.…”

“…The ranks are chosen based on the estimated post IRC SINR. 1 The proposed rank coordination mechanism is not bound to any specific rank adaptation algorithm, though interference-aware rank adaptation algorithms such as those presented in [12] are best suited for such applications.…”
