摘　　要：为解决无人机(UAV)辅助多频段异构网络下行链路传输的无线电资源管理问题,提出了一种基于无人机辅助毫米波异构蜂窝网络的无线电资源管理优化方法。首先,建立了一个多频段毫米波蜂窝网络系统模型,确定了无人机在最大路径损耗内的最佳飞行高度。其次,基于网络内外层关系,提出了一种两层优化方法,从而获得每个无人机的最佳覆盖半径,实现宏基站层能量效率的最大化。最后,通过搭建混合蜂窝网络对所提方法进行试验验证。试验结果表明:所提方法能够实现系统能量效率的最大化,且与其他对比方法相比,所提方法的系统能量效率优于功率最小化和速率最大化的传统功率分配方法。To solve the problem of radio resource management in the downlink transmission of UAV-assisted multi-band heterogeneous networks,an optimization method of radio resource management based on UAV-assisted millimeter wave heterogeneous cellular networks is proposed.Firstly,a multi-band millimeter wave cellular network system model is established to determine the optimal flight altitude of the UAV within the maximum path loss.Secondly,based on the relationship between the inner and outer layers of the network,a two-layer optimization method is proposed to obtain the best coverage radius of each UAV and maximize the energy efficiency of the macro base station layer.Finally,the proposed method is experimentally verified by building a hybrid cellular network.The experimental results show that the proposed method can maximize the energy efficiency of the system,and compared with other comparison methods,the system energy efficiency of the proposed method is better than the traditional power allocation method of power minimization and rate maximization.
