“…Spectrum splitting is the easiest way to avoid interference in D2D enabled cellular network. Adopting time division multiplexing (TDM) technology to separate cellular and D2D transmissions could effectively reduce the interference level in the hybrid cellular network with D2D communication [53][54][55]. However, this method would lead to inefficient utilization of the available spectrum.…”

Interference Mitigation in Device‐to‐Device Communications

The mobile data traffic has risen exponentially in recent days due to the emergence of data intensive applications such as online gaming, video sharing etc. It is driving the telecommunication industry as well as the research community to come up with new paradigms that will support such high data rate requirements within the existing wireless access network, in an efficient and effective manner. To respond to this challenge, Device-to-Device (D2D) communication in cellular networks is viewed as a promising solution, which is expected to operate, either within the coverage area of the existing eNB and under the same cellular spectrum (in-band) or separate spectrum (outband). D2D provides the opportunity for users located in close proximity of each other to communicate directly, without traversing data traffic through the eNB. It results in several transmission gains, such as improved throughput, energy gain, hop gain, reuse gain, etc. However, integration of D2D communication in cellular systems at the same time introduces new technical challenges that need to be addressed. Containment of the interference among D2D nodes and cellular users is one of the major problems. D2D transmission radiates in all directions, generating undesirable interference to primary cellular users and other D2D users sharing the same radio resources resulting in severe performance degradation. Efficient interference mitigation schemes are a principal requirement in order to optimize the system performance. This work presents a comprehensive review of the existing interference mitigation schemes present in the open literature. Based on the subjective and objective analysis of the work available to date, it is also envisaged that adopting a multi-antenna beamforming mechanism with power control such that the transmit power is maximized towards the direction of the intended D2D receiver node and limited in all other directions will minimize the interference in the network. This could maximize the sum throughput and hence, guarantees the reliability of both the D2D and cellular connections.

In cellular communication systems, the introduction of device-to-device (D2D) communications provides a reasonable solution to facilitate high data rate services in short-range communication. However, it faces a challenging issue of interference management, where the cross-tier interference from D2D users to licensed cellular users (CUs) degrades their quality-of-service (QoS) requirements. D2D communications can also assist in offloading some nearby CUs to enhance the cellular operator's benefit. To encourage the D2D transmitters (D2DT) to provide service to CUs in the dead zone, the cellular base station (CBS) needs to incentivize it with some monetary benefits. In this paper, a Stackelberg game-based joint pricing framework for interference management and data offloading is presented to illustrate the effects of cooperation between the D2D user and CBS. Specifically, a singular price is used to incentivize the D2DT to share its resources with the far-off CUs along with penalizing them for interference created at CBS. Simulation results illustrate the performance of the proposed technique in terms of the utilities of CUs and D2D users for varying distances of D2DT.Electronics 2020, 9, 408 2 of 13 is not used by proximal cellular users (CU). This technique perhaps may not increase spectrum usage considering that D2D devices use a distinct resource with the CUs. (ii) Underlay mode: In underlay or reuse mode, D2D devices can use the same spectrum resource as the cellular users, on the condition of creating tolerable interference to their communication. This mode can substantially enhance system capacity. Moreover, the cellular operators can also make more profit through additional charges obtained from CUs for providing D2D service. In this paper, the focus is on the underlay spectrum sharing mode, where the D2D pairs reuse the spectrum of the CUs. One of the fundamental research challenges in reuse mode is the severe interference created in the cellular network by D2D communication due to the usage of shared spectrum resources. To ensure the quality-of-service (QoS) of cellular users, various interference mitigation techniques have been studied in the literature. In [8], the authors proposed a power control mechanism to control the peak transmission power of D2D transmitters (D2DT) by the base station. In [9], a more innovative technique was introduced, where resource allocation along with the power control technique was used to combat the interference from D2D to cellular users and vice versa. A spectrum splitting framework was developed in [10] to minimize interference in the D2D-cellular network. To assist in the uplink transmission of CUs to BS, relay nodes were selected in [11], and network coding was applied for the actual transmission. In [12], a multiple-input and multiple-output (MIMO) beamforming technique for the multiple-antenna D2D underlying cellular network based on estimated channel state information (CSI) was presented.In addition to interference management using power control, our scheme essenti...

“…These include the difficulties in accurately modeling the interference induced by cellular and D2D UEs, and consequently optimizing the resource allocation based on the interference model. Most of the previous works published in this area have relied on system-level simulations with a large parameter set [11], meaning that it is difficult to draw general conclusions. Recently, stochastic geometry has received considerable attention as a useful mathematical tool for interference modeling.…”

Device-to-device (D2D) communications are now considered as an integral part of future 5G networks which will enable direct communication between user equipment (UE) without unnecessary routing via the network infrastructure. This architecture will result in higher throughputs than conventional cellular networks, but with the increased potential for co-channel interference induced by randomly located cellular and D2D UEs. The physical channels which constitute D2D communications can be expected to be complex in nature, experiencing both line-of-sight (LOS) and non-LOS (NLOS) conditions across closely located D2D pairs. As well as this, given the diverse range of operating environments, they may also be subject to clustering of the scattered multipath contribution, i.e., propagation characteristics which are quite dissimilar to conventional Rayeligh fading environments. To address these challenges, we consider two recently proposed generalized fading models, namely κ − µ and η − µ, to characterize the fading behavior in D2D communications. Together, these models encompass many of the most widely encountered and utilized fading models in the literature such as Rayleigh, Rice (Nakagami-n), Nakagamim, Hoyt (Nakagami-q) and One-Sided Gaussian. Using stochastic geometry we evaluate the rate and bit error probability of D2D networks under generalized fading conditions. Based on the analytical results, we present new insights into the trade-offs between the reliability, rate, and mode selection under realistic operating conditions. Our results suggest that D2D mode achieves higher rates over cellular link at the expense of a higher bit error probability. Through numerical evaluations, we also investigate the performance gains of D2D networks and demonstrate their superiority over traditional cellular networks.
