In this paper, we study the energy-efficient resource allocation problem for device-to-device (D2D) communication underlaying cellular networks which aims to maximize the minimum weighted energy-efficiency (EE) of D2D links while guaranteeing the minimum data rates for cellular links. We first characterize the optimal power allocation of the cellular links to transform the original resource allocation problem into the joint subchannel and power allocation problem for D2D links. We then propose three resource allocation algorithms with different complexity, namely Dual-Based, Branch-and-Bound (BnB), and Relaxation-Based Rounding (RBR) algorithms. While the Dual-Based algorithm solves the problem by using dual decomposition method, the BnB and RBR algorithms tackle the problem by employing the relaxation approach. We establish the strong performance guarantees for the proposed algorithms through theoretical analysis. Extensive numerical studies demonstrate that the proposed algorithms achieve superior performance and significantly outperform a conventional algorithm.

“…equipment, Oduola et al obtained the transmission power range of the D2D users, but the power control scheme cannot reach the maximum system throughput [10]. In [11], the base station is planning an interference limited area around the D2D receiver by setting the lower bound of SNR of the D2D communication.…”

Abstract. The introduction of Device-to-Device (D2D) communication technology can effectively improve the utilization ratio of spectrum resources of cellular networks. However, when D2D communication multiplexes cellular spectrum resources, the cellular signal and D2D signal would not be obtained by cellular user or D2D receiver due to the interference between cellular signal and D2D signal. To solve this problem, a D2D relay transmission algorithm based on complex field network coding (CFNC) is proposed in this paper. Specifically, as CFNC is adopted in the relay node to encode the received cellular signal and D2D signal, cellular signal and D2D signal are recovered respectively by the D2D receiver and the cellular user with maximum likelihood detection. Performance analyses and simulation results show that, compared with the traditional D2D transmission algorithm, the proposed algorithm can significantly improve the system achievable rate, and moreover reduce the outage probability.
