“…where γ c min and γ d min denote the minimum SINR requirements of CU and D2D pair, respectively, P c max and P d max are the maximum transmission power of the CU and D2D pair, respectively. Constraints (12) and (13) are the QoS requirements of CUs and D2D pairs, respectively. Constraint (14) guarantees that transmission power of CUs, BS, and D2D pairs are within the maximum limit.…”

“…One is the uplink resource allocation for D2D communications [12][13][14][15][16][17][18][19][20]. Specifically, in order to achieve the maximum total data transmission rate, different types of methods are proposed, such as range division [12], mode selection [13][14][15], and power control [14,15]. In reference [16], the authors focus on power control and channel assignment for interference coordination between D2D pair and CU in uplink phase.…”

“…However, these methods in references [12][13][14][15][16][17][18][19][20][21] reuse the uplink channel, and in references [21][22][23][24][25][26][27][28] D2D users can share the downlink channel, therefore the total radio spectrum has not been fully utilized. To account for this problem, jointly uplink and downlink channel scheme [29,30] are proposed in cellular networks.…”

In cellular networks, device-to-device communications can increase the spectrum efficiency, but some conventional schemes only consider uplink or downlink resource allocation. In this paper, we propose the joint uplink and downlink resource allocation scheme which maximizes the system capacity and guarantees the signal-to-noise-and-interference ratio of both cellular users and device-to-device pairs. The optimization problem is formulated as a mixed integer nonlinear problem that is usually NP hard. To achieve the reasonable resource allocation, the optimization problem is divided into two sub-problems including power allocation and channel assignment. It is proved that the objective function of power control is a convex function, in which the optimal transmission power can be obtained. The Hungarian algorithm is developed to achieve joint uplink and downlink channel assignment. The proposed scheme can improve the system capacity performance and increase the spectrum efficiency. Numerical results reveal that the performance of the proposed scheme of jointly uplink and downlink is better than that of the schemes for independent allocation.

“…Since the D2D communication and the cellular communication share the same resource in the underlay inband mode, one of the most important issues in this variant of D2D communication is the interference problem. As a result, most current literature on D2D communication focuses on interference management and resource allocation issues [9], [10], [11], [12], [13], and study how to maximally utilize the potential gains of D2D-aided cellular networks. The underlying assumption in these works is that the interference caused by resource sharing, is harmful and needs to be mitigated, eliminated, or avoided via various techniques.…”

“…However, a direct D2D communication may have some limitations, for example if the distance between D2D-capable UEs (DUEs) is not short enough to facilitate a high-quality D2D transmission or the channel conditions between them are poor. To this end, a two-hop relay-assisted D2D communication [13], [25], [26], [27], [28], [29] has attracted a great deal of attention recently since it can effectively improve the system performance in terms of link capacity, robustness and low propagation delays. In relay-aided D2D communication, a device having a better geometry to the transmitter device or base station may act as a relay for the receiver device.…”

In this paper, we propose a relay-assisted device-to-device (D2D) communication as an underlay in a cellular network, where two sequential best relay nodes based on different selection criteria are chosen. Novel analytical expressions of the secrecy outage probability (SOP) and the probability of nonzero secrecy capacity (PNSC) are derived to evaluate the secrecy performance of the cellular network. In addition, we derive a simple and explicit approximation of the SOP in the high signal-to-noise ratio (SNR) to gain some insights on how various system parameters affect the aforementioned secrecy performance. Also, for the sake of comparison, the analytical SOP expression when only the cellular network exists, i.e., without the interference of the D2D communication, is obtained. Furthermore, to assess the usefulness of the cooperation between the D2D communication and the cellular network, we derive an analytical expression for the mutual outage probability (MOP) which represents the true outage probability across both the cellular and D2D networks. An asymptotic analysis of the MOP in the high SNR regime is obtained and the diversity order is derived. Finally, our proposed mathematical framework is compared with Monte-Carlo simulations to verify the accuracy of the derivations.

Summary This paper addresses the research question of total system interference minimization while maintaining a target system sum rate gain in an inband underlay device‐to‐device (D2D) communication. To the best of our knowledge, most of the state of the art research works exploit offline resource allocation algorithms to address the research problem. However, in Long‐Term Evolution (LTE) and beyond systems (4G, 5G, or 5G+), offline resource allocation algorithms do not comply with the fast scheduling requirements because of the high data rate demand. In this paper, we propose a bi‐phase online resource allocation algorithm to minimize the total system interference for inband underlay D2D communication. Our proposed algorithm assumes D2D pairs as a set of variable elements whereas takes the cellular user equipment (UEs) as a set of constant elements. The novelty of our proposed online resource allocation algorithm is that it incurs a minimum number of changes in radio resource assignment between two successive allocations among the cellular UEs and the D2D pairs. Graphical representation of the simulation results suggests that our proposed algorithm outperforms the existing offline algorithm considering number of changes in successive allocation for a certain percentage of sum rate gain maintaining the total system interference and total system sum rate very similar.
