Uplink Resource Allocation in Device-to-Device Communication System

摘要：

　　In this paper,we study uplink resource allocation problem to maximize the overall system capacity while guaranteeing the signal-to-noise ratio of both D2D users and cellular users(CUs).The optimization problem can be decomposed into two subproblems: power control and channel assignment.We first prove that the objective function of power control problem is a convex function to get the optimal transmit power.Then,we design an optimal selection algorithm for channel assignment.Numerical results reveal the proposed scheme is capable of improving the systems performance compared with the random selection algorithm.
