摘要: 蜂窝连接无人机(cellular-connected UAV)在5G网络中展现出巨大潜力。针对其在执行通信任务时需保持稳定地面基站连接的问题,研究了无人机轨迹优化。目标是在给定区域内,使无人机从起点到终点的飞行过程中联合最小化任务完成时间与通信中断时间,并最大化通信吞吐量。由于该问题具有非凸性,采用基于多步学习的竞争性双深度Q网络(Dueling Double Deep Q Network, D3QN)算法求解,通过无人机与地面基站的交互学习实现自适应轨迹优化。仿真结果表明,与直飞策略相比,该方法将任务完成时间缩短了28%,通信中断时长降低了42%,系统平均吞吐量提升了35%,在任务效率、通信稳定性和系统吞吐量等方面均实现显著优化。

Abstract: Cellular-connected unmanned aerial vehicles (UAVs) show great potential in 5G networks. To address the challenge of maintaining stable connections with ground base stations during communication tasks, this paper investigates an UAV trajectory optimization problem. The objective is to jointly minimize the task completion time and communication outage duration while maximizing communication throughput as the UAV travels from the starting point to the destination within a given area. Considering the non-convex nature of the problem, a multi-step learning-based Dueling Double Deep Q Network (D3QN) algorithm is adopted to achieve adaptive trajectory optimization through interactive learning between the UAV and ground base stations. Simulation results show that, compared with the direct flight strategy, this method reduces the task completion time by 28%, cuts down the communication outage duration by 42%, and increases the average system throughput by 35%, achieving significant improvements in task efficiency, communication stability and system throughput.

引言

近年来,无人机(Unmanned Aerial Vehicle, UAV)凭借其高机动性与灵活部署能力,在诸多领域迅速发展[1][2]。在无人机的各类应用场景中,保障其飞行安全与提升任务完成时效至关重要,而这两者均依赖于稳定且高质量的空地通信链路。为此,蜂窝连接无人机(cellular-connected UAV)作为无人机与地面基站之间的重要无线连接方式,受到广泛关注[3]。与通信距离受限的传统WiFi方案相比,蜂窝连接不受短距约束[4],可实现真正意义上的远程控制;相较于覆盖范围广的卫星通信,蜂窝连接无人机亦具有显著成本优势。尤其是在第五代移动通信技术[4]的支撑下,蜂窝连接无人机有望显著提升空地链路的速率与可靠性。近年来,蜂窝连接无人机已在搜救、空中监测、交通管控、航拍以及包裹投递等领域获得成功应用。
