| D2D(Device-to-Device)通信是一种在基站的控制下,允许终端之间通过复用小区资源直接通信的新型技术.它能够增加蜂窝通信系统频谱效率,降低终端发射功率,在一定程度上解决了无线通信系统频谱资源匮乏的问题.由于在未来的移动网络中有越来越多的异构设备,一个高效的资源分配方案必须最大限度地提高系统的吞吐量,并实现更高的频谱效率.资源分配方案是在保证小区用户吞吐量的前提下,使D2D用户获得最大的吞吐量,并在文献［7］的基础上给出了一个算法来解决这个问题.通过仿真表明,算法具有较低的时间复杂度,能够有效地提高系统的吞吐量. |

| Abstract: |
| 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. |
