摘　　要：为解决基于能量收集的D2D(设备到设备)异构网络的资源分配问题,提升D2D链路的平均能量效率,提出一种高效的资源分配方法。基于系统模型分析,提出非凸的混合整数非线性约束优化问题;将非凸优化问题等效转化为凸优化问题,运用Karush-Kuhn-Tucker条件进行最优求解;提出一种结合能量收集时隙分配、资源块和功率分配的迭代算法,通过仿真分析验证所提方法的有效性。实验结果表明,所提方法能够在保证能量收集约束和蜂窝用户设备服务质量的情况下,最大限度地提高所有D2D链路的平均能量效率,与其它几种方法相比,所提方法在不同的网络参数设置下均能实现更高的能量效率。To solve the resource allocation problem of D2D(device-to-device)heterogeneous networks based on energy harvesting and improve the average energy efficiency of D2D links,an efficient resource allocation method was proposed.Based on the analysis of the system model,a non-convex mixed integer nonlinear constrained optimization problem was proposed.The non-convex optimization problem was equivalently transformed into a convex optimization problem,and the Karush-Kuhn-Tucker condition was used for optimal solution.An iterative algorithm combining energy harvesting time slot allocation,resource block and power allocation was proposed,and the effectiveness of the proposed method was verified by simulation analysis.Experimental results show that the proposed method can maximize the average energy efficiency of all D2D links while ensuring energy harvesting constraints and cellular user equipment service quality.Compared with other methods,the proposed method can achieve higher energy efficiency under different network parameter settings.
