摘　　要：由于无人机基站在不同应用场景下,所处的地理环境、用户分布、用户需求和所希望提升的性能需求不同,需要根据不同应用场景的特征对无人机基站进行部署。基于无人机基站的典型应用场景,构建两个具有代表性的无人机基站应用场景模型,并对应用场景模型特征进行抽象描述。分别构建了两个应用场景的空地通信传输模型。在此基础上,给出了最大化传输速率以及最大化无人机覆盖范围的无人机基站最优飞行高度的数学计算模型。最后,对不同场景下无人机基站最优飞行高度的影响因素和变化趋势进行了分析。Due to the different geographic environment, user distribution, user requirements and performance requirements of Unmanned Aerial Vehicle(UAV) base stations in different application scenarios, it is necessary to deploy UAV base stations according to the characteristics of different application scenarios. Based on the typical application scenarios of UAV base station, two representative UAV base station application scenario models are constructed, and the features of the application scenario models are described abstractly. The air ground communication transmission models of two application scenarios are constructed respectively. On this basis, the mathematical calculation model of the optimal flight height of UAV base station is given to maximize the transmission rate and the coverage of UAV. Finally, the influencing factors and changing trends of UAV base station optimal flight altitude in different scenarios are analyzed.
