Abstract

Device-to-device (D2D) communication as an underlay to cellular networks is a promising technology to improve network capacity and user experience. However, it depends on elegant resource management between cellular users and D2D pairs. In this work, we study the problem of D2D communication underlaying cellular networks sharing uplink resources, which focuses on maximizing the sum rate of D2D pairs while guaranteeing the quality of existing cellular users. A three-step scheme is proposed. We first conduct mode selection to decide whether a D2D pair can share links with a cellular user. And then, we match a cellular user with each D2D pair based on the principle of fairness and try to maximize the sum rate of D2D pairs. Finally, a joint power control strategy is developed and a closed-form of solution is provided. The superiority of the proposed scheme is demonstrated in the numerical results.
