In the mixed network which consists of cellular and device-to-device

there is a dynamic resources allocation problem in multi-cell D2 Dcommunication system when the interference between the users of intra-cell and inter-cell is considered.In this paper

we design a utilityfunction with interference control of the transmitted power of D2 Dusers after introducing the non-cooperative game theory and pricingmechanism.This utilityfunction not only considers the fairness but also the interference of the system.Then we demonstrate the existence and uniqueness of Nash equilibrium in a power control model

which indicate that the D2 Dusers can achieve a stable state after the games.Simulation results show that the proposed algorithm not only improves the fairness among the users

but also increases the throughputs and improves the performances of the system.
