Efficient and timely sharing of critical information is crucial for Public Safety (PS) communications, which can be fulfilled using one of the cutting-edge technologies, Device-to-device (D2D) communication. During an emergency, the PS applications should be prioritized over other applications, ensuring the emergency messages reach the first responders in time. Due to its inherent characteristics, the evolved Node Base station will not prioritize or categorize the D2D communication based on its application type, thus treating all applications equally. Further, D2D communication introduces significant interference to cellular users and vice-versa while sharing resources, and it is vital to reduce the impact of these interferences to ensure the Quality of Service for all users in the network. Hence, this article proposes a novel interference management approach to increase the overall sum rate of the system. In addition, the proposed approach also allows more D2D communication in general, particularly PS applicationbased D2D communication, to be active in the network. As the formulated problem is a Mixed-Integer Non-Linear Programming (MINLP) type of problem, it is split into two sub-problems, namely, Iterative Resource Allocation and Sharing and Iterative Power Optimization to achieve a polynomial time complexity. The theoretical proofs adequately explain the algorithm's time complexity and convergence property. The simulation results show that the proposed system enhances the overall sum rate by allowing more active PS D2D applications in the network.INDEX TERMS D2D communication, power optimization, interference management, iterative algorithm, one-to-one resource allocation.Recent research explores the possibility of sharing the Resource Blocks (RBs) (the smallest chunk of the spectrum) of Cellular User Equipment (CUEs) with D2D User Equipment (DUE) in underlay in-band communication to significantly enhance spectrum efficiency [4]. The different resource-sharing strategies in practice are one-to-one, oneto-many, and many-to-many. In the one-to-one technique,

“…-Phase 1 : If the number of channel is C and u is the number of users, out of U total users, to be multiplexed on each channel and the total possible combination of user assignment to channel is n then the complexity of ESM scheme for each combination is given as: The computational complexity of IPM is given as γ 0.5 (γ + θ)θ 2 [27], where γ is interpreted as the number of inequality constraints and θ is defined as the number of variables. Therefore, the overall complexity of the problem is O(…”

Non orthogonal multiple access (NOMA) is expected to be the most significant and viable solution for fifth generation (5G) communication system due to its incredible advantage of spectral efficiency. This paper proposes joint channel allocation and power optimization for downlink NOMA system, so as to maximize the system throughput while preserving the minimum data rate of every user equipment necessary to maintain quality of service and successive interference cancellation constraint. The optimization problem so formulated is a joint mixed integer nonlinear programming problem. Hence, two stage solution is proposed that uses mosek solver for channel assignment followed by power allocation across assigned channels. We use the difference between two convex functions (DC) programming technique for modifying the nonconvex optimization problem into a convex subproblem. Thus, we achieve efficient and fair power allocation coefficients across channels by solving the convex subproblem iteratively. Simulation results demonstrate better efficiency of our proposed scheme for resource allocation compared to some of the existing baseline schemes.

“…On the one hand, the D2D pairs reusing the cellular spectrum will disturb the communication of CUs. On the other hand, the D2D devices sharing the spectrum will be interfered by the corresponding CUs [11,12]. Especially, the interferences will be more serious in many-to-many scenario, where one channel resource can be reused by multiple D2D pairs, and a D2D pair can reuse multiple channel resources.…”

Device-to-device (D2D) communication is one of the promising technologies for the next-generation cellular network, which uses direct communication between two neighboring devices to obtain a high transmission rate. This paper focuses on wireless resource allocation in a many-to-many D2D communication scenario to maximize the D2D transmission sum rate. Through the model analysis, the objective function is formulated while guaranteeing the minimum transmission rate of both the cellular users (CUs) and the D2D pairs. Based on the candidate sequence, an overlapping coalition game algorithm is proposed to enhance the D2D transmission sum rate. Furthermore, the preference sequence of CUs is adopted in the coalition initialization. According to the interference intensity, a power allocation scheme is designed further to improve the transmission sum rate of the D2D pairs. The simulation results have verified the validity of the proposed algorithm.
