【 摘 要 】

D2D (Device-to-Device) communication is under the control of base station,allowing direct communication between the terminal reusing the cell resources.It is possible to increase the spectral efficiency of a cellular communication and to reduce the transmit power of the terminal.Due to a growing number of heterogeneous devices in the future mobile network,an efficient resource allocation scheme must maximize the throughput of the system and achieve higher spectral efficiency.This paper presents an efficient resource allocation scheme to ensure the cell user throughput premise that D2D users get maximum throughput.In addition,the proposed greedy algorithm could solve the problem of resource allocation efficiently.The simulation results show that our algorithm has a lower complexity and can improve system throughput effectively.
