摘要：
We investigate power control problem for cooperative relaying in the device-to-device (D2D) system underlaying cellular networks. Specifically, we consider the D2D communication assisted by fixed-location relays in interference existing circumstance. Therefore, an effective power control scheme is of great importance to suppress interference between D2D and cellular communications which can improve the total system throughput and spectral efficiency. In this paper, we formulate a power control optimization problem for cellular communication and a simple on-off power control algorithm for D2D communications. We also obtain analytic expression for the coverage probability of cellular link using stochastic geometry according to proposed algorithm. Simulation results follow to show the rate of both cellular and D2D links in the various number of D2D transceivers.
