Abstract:

Device-to-device(D2D)communication is a promising component in the fifth generation systems,and it can significantly improve both system-side and user-side performance.However,the prior works are mainly focused on addressing the system-side metrics.Therefore,a balance was struck between EE and UF by joint consideration of power control(PC)and temporal and spectral scheduling(TSS).Specifically,PC was intended to maximize the EE of the D2D user.Based on the above results,TSS determined the set of admitted D2D users and their allocated spectral resources.Moreover,the weights were updated by the idea of proportional fairness dynamically.Finally,the numerical results show the efficiency of the efficiency mechanism and the tradeoff between EE and UF.

Key words: device-to-devicecommunication, energyefficiency, userfairness, powercontrol, temporalandspectralscheduling
