蜂窝控制下的D2D通信的无线资源分配研究
Wireless resource allocation for device to device(D2D) communication underlaying cellular networks

在引入D2D通信的状况下，为改进蜂窝用户无线资源分配的公平性，文中提出了一种CU用户和D2D用户非正交共享无线资源的EFRA方案，该方案运用降低权重影响因子的方法，减少了D2D通信对蜂窝用户的影响，实验分析说明，该方案在牺牲部分D2D通信的吞吐量的情况下，不仅能够提高蜂窝用户接受服务的公平性，而且能很好地保护蜂窝用户的吞吐量。
In order to improve the fairness of resource allocation for cellular users, considering device to device (D2D) communication underlaying cellular networks, the EFRA scheme is proposed to optimize the resource allocation and the power control between the cellular and D2D connections for sharing the same resources. By using the concept of priority impact factor, the EFRA scheme can reduce the unwanted effect on the cellular users by D2D connections. The experimental analysis shows that the scheme can improve the fairness of resource allocations among the cellular connections, and protect the throughput of the cellular connections
