摘要

本文研究了在郊区稀疏环境中蜂窝连接无人飞行器(UAV)的干扰感知联合路径规划和功率分配机制。无人飞行器的目标是从初始点出发,沿小区移动到达目的地,以保证所需的服务质量(QoS)。特别是,考虑到最短路径和飞行资源的限制,无人机的目标是最大限度地提高上行链路吞吐量,并最大限度地减少对连接到邻近蜂窝基站(BS)的地面用户设备(UE)的干扰。为了对代理(即无人机)进行培训,利用专家知识来体验场景并定义所需的行为。为了解决这个问题,我们在 Q-learning 和深度强化学习(DRL)的基础上,通过反强化学习(IRL)采用了一种学徒学习方法。该方法的性能与使用监督学习方法从名为行为克隆(BC)的演示技术中学习的性能进行了比较。仿真和数值结果表明,所提出的方法可以达到专家级的性能。我们还证明,与 BC 技术不同,我们提出的方法在不可见的情况下性能不会下降。

Joint path planning and power allocation of a cellular-connected UAV using apprenticeship learning via deep inverse reinforcement learning

This paper investigates an interference-aware joint path planning and power allocation mechanism for a cellular-connected unmanned aerial vehicle (UAV) in a sparse suburban environment. The UAV’s goal is to fly from an initial point and reach a destination point by moving along the cells to guarantee the required quality of service (QoS). In particular, the UAV aims to maximize its uplink throughput and minimize interference to the ground user equipment (UEs) connected to neighboring cellular base stations (BSs), considering both the shortest path and limitations on flight resources. Expert knowledge is used to experience the scenario and define the desired behavior for the sake of the agent (i.e., UAV) training. To solve the problem, an apprenticeship learning method is utilized via inverse reinforcement learning (IRL) based on both Q-learning and deep reinforcement learning (DRL). The performance of this method is compared to learning from a demonstration technique called behavioral cloning (BC) using a supervised learning approach. Simulation and numerical results show that the proposed approach can achieve expert-level performance. We also demonstrate that, unlike the BC technique, the performance of our proposed approach does not degrade in unseen situations.
