Abstract
In this paper, we investigate a resource allocation scheme for fully loaded distributed antenna system (DAS) with Device-to-Device (D2D) communication. A framework of resource allocation for D2D communications under laying a fully loaded DAS is presented, where the objective is to maximize the throughput of shared spectrum channel. First, we set up DAS with D2D communication model. Then, a dual threshold power control scheme is studied for each D2D pair and its cellular user (CU) partner to maximize the throughput of shared spectrum channel. Finally, the optimal solution is obtained according to the convex optimization theory. Numerical results show that the proposed scheme can significantly improve the throughput and communication quality of communication network system compared to the co- located antenna system (CAS) with D2D communication.
