“…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.

“…As per the author's literature survey, most of the distributed algorithm are based on game theory that are not reliable to converge. Only few works consider the distributed solution without applying game theory in previous studies . A distributed matching is given in Holfeld and Jorswieck for many to many pairing where matching of channels and D2D pairs is done on the basis of local CSI without consideration of CUs in the system.…”

“…But, the work is limited to one CU only and therefore pairing problem is not taken into consideration. A distributed method is developed for mode selection and power allocation in Abedin and Rasti . Further, a different approach is proposed in Khuntia and Hazra for channel and power allocation in underlay D2D to maximize overall sum rate by applying deep Q‐learning with no prior traffic knowledge at the BS.…”

Device-to-device (D2D) communication is a viable solution proposed by the Third Generation Partnership Project (3GPP) to handle the enormous number of devices and expected data explosion in 5G. It is competent in enhancing the system performances such as increased data rate, reduced delay, and less power consumption while maintaining a low load on the base station (BS). In this paper, channel assignment and power control scheme is proposed for underlay D2D system where one cellular channel is allowed to be shared among multiple D2D pairs. This will lead to enhanced spectral efficiency on the cost of additional interferences introduced among the D2D and cellular users (CUs). Our aim is to maximize the D2D throughput without degrading the performance of existing CU that is sharing the channel with D2D. This is achieved by maintaining a threshold signal-to-interference-plus-noise ratio (SINR) for each CU. A centralized channel assignment algorithm based on the well-known two-sided preference Gale-Shapley algorithm is proposed, named as RAbaGS-HR. Further, suboptimal distributed power control (DPC) algorithms are proposed for both uplink and downlink D2D. The novelty of the work lies in the facts that a channel is shared among multiple D2D users and the optimal power is calculated for all the users sharing the same channel under the full consideration of all kinds of interferences unlike most of the existing work that either assumed the fixed CU power or ignored the interferences among the D2D users. Numerical results show the efficacy of the proposed algorithms in terms of significant gain in throughput with a very low computational cost. In addition to this, the energy efficiency (EE) is also analyzed for different D2D user density, with respect to average circuit power consumption and D2D maximum transmit power.

“…The proposed mode selection is user controlled. In the work of Abedin and Rasti, each transmitter makes a decision on D2D or CMs by comparing the effective interference at its serving BS and its corresponding receiver. Consecutively, the power allocation is performed to guarantee the rate requirements for the users and to maximize the system throughput.…”

In this paper, we consider the problem of mode selection, resource allocation, and power control for device‐to‐device (D2D) communications in cellular networks. We propose optimization frameworks based on max‐min fairness and proportional fairness where cellular and D2D links share the cellular resources. The optimization problem is solved in different resource sharing modes (ie, cellular, overlay, and underlay), and the mode leading to the highest optimal value is selected in the system. We further propose a two‐stage mode selection scheme based on channel quality in which the resource partitioning is expressed in closed form. We compare the performance of the proposed schemes with that of optimization framework based on sum‐rate and no‐mode selection scheme. The numerical results indicate that cellular and D2D links achieve higher rates in proportional fairness and max‐min fairness schemes compared to no‐mode selection scheme. While the rate improvement of D2D link is more significant in sum‐rate optimization, the cellular link may achieve lower rate in this scheme compared to other methods including the no‐mode selection scheme. The results also reveal that the rates of cellular and D2D links in channel quality scheme can vary within the range of rates obtained in max‐min and sum‐rate optimization frameworks.
