Title
An optimal resource reuse strategy for QoS-awared device-to-device communications
Abstract
Device-to-device (D2D) communication is a promising technique for improving the spectral efficiency of cellular networks. In this paper, we consider joint optimization of pair assignment and power control for D2D pairs reusing downlink cellular resources, and aim to maximize the aggregate rate of D2D communications while guaranteeing the quality of service (QoS) of the cellular users. By transforming the original difficult problem into an equivalent form, we are able to analytically characterize the optimal power control and pair assignment for the D2D and cellular users. Based on these results, we then propose an efficient algorithm to obtain the jointly optimal power control and pair assignment strategy. The numerical results show the superiority of our proposed method over existing ones.
