Device to Device (D2D) communication has emerged as the most promising paradigm for optimizing spectral and energy efficiency, reliability as well as increasing network throughput in the emerging cellular generation. D2D resource optimization scheme has been thoroughly investigated in the literature to manage interference and enable its smooth integration into the future cellular network in recent years as an increasing number of papers are published each year. We believe systematic categorization of literature in the area will help readers to comprehend the strengths, weaknesses, and trends of the solution approach. However, a survey that discusses all aspects, requirements, and challenges of D2D resource optimization is largely missing. Hence, in this paper, we aim to develop a comprehensive survey that fills the gaps found in the previous literature. Based on the surveyed papers, it will figure out ideas that have been thoroughly explored and those that assume the potential for further research.

Next generation cellular networks require high capacity, enhanced energy efficiency and guaranteed quality of service (QoS). In order to meet these targets, device-to device (D2D) communication is being considered for future 5th generation especially for certain applications that require the proximity gain, the reuse gain, and the hop gain. In this paper, we investigate energy efficient power control for the uplink of an OFDMA (orthogonal frequency-division multiple access) single-cell communication system composed of both regular cellular users and device to device (D2D) pairs. Firstly, we analyze and mathematically model the actual requirements forD2D communications and traditional cellular links in terms of minimum rate and maximum power requirement. Secondly, we use fractional programming in order to transform the original problem into an equivalent concave one and we use the non-cooperative Game theory in order to characterize the equilibrium. Then, the solution of the game is given as a water-filling power allocation. Furthermore, we implement a distributed power allocation scheme using three ways: a) Fractional programming techniques b) Closed form expression (the novelty is the use of wright omega function). c) Inverse water filling. Finally, simulations in both static and dynamic channel setting are presented to illustrate the improved performance in term of EE, SE (spectral efficiency) and time of execution of the iterative algorithm (Dinkelbach) than the closed form algorithms.

“…An interference aware resource allocation algorithm was proposed in [6], where base station allocates DUEs RBs that preassigned to CUEs least interfering with the DUEs, but the quality of service(QoS) of CUEs are not taken into consideration. Iliev et al [7] adopt a simple power control algorithm to reduced influence by setting limited power threshold, this scheme is simple but does not take the distance between DUEs and CUEs into account. A three-step scheme has been proposed in [8], it allocates powers for each admissible D2D pair and its potential CUEs, then choses an appropriate CUE for each D2D pair.…”

Abstract. Device-to-device (D2D) communications has proven to be efficient in improving the network performance and releasing the traffic load of base station. D2D user equipment(DUEs) can share the same LTE resources blocks with the cellular user equipment(CUEs), but it would cause severe co-channel interference. In this paper, a resource allocation and power control scheme is proposed to reduce the impact of co-channel interference. First, adopt a resource allocation scheme based on greedy algorithm on the premise of meeting the minimum rate requirements of devices, then the path loss compensation factor matrix could be calculated according to the distance between DUEs to the base station and CUEs and used to reduce the influence. Simulation results show that the proposed algorithm has better performance in D2D user access rate and system throughput.
