Base Station Deployment under EMF constrain by Deep Reinforcement learning

  • 结合生成对抗网络与深度Q网络,实现基站位置的智能决策。
  • 推理时间从数小时缩短至秒级,支持实时动态部署。
  • 适用于5G/6G网络中复杂场景下的高效设计与合规评估。

随着5G网络快速扩展及6G技术的兴起,密集组网、毫米波通信和动态波束成形成为趋势,对可扩展的仿真工具需求日益迫切。此类工具需高效评估覆盖范围与射频电磁场(RF-EMF)暴露等关键性能指标,辅助网络设计并确保符合安全规范。基站(BS)部署是网络设计的核心任务,需满足覆盖要求。基于前期工作,本文提出一种条件生成对抗网络(cGAN),可从网络拓扑图像中同时预测特定位置的接收信号强度(RSS)与电磁场暴露水平。进一步,针对网络设计应用,提出基于训练好的cGAN的深度Q网络(DQN)框架,用于最优基站部署。相比传统射线追踪仿真,所提cGAN将推断与部署时间从数小时压缩至秒级。不同于独立的cGAN仅生成静态性能图,该GAN-DQN框架可在覆盖与暴露约束下进行序列决策,学习直接解决基站部署问题的有效策略,适用于满足预设异构性能目标的动态场景中的实时设计与适应。

原文摘要 · Abstract (English)

As 5G networks rapidly expand and 6G technologies emerge, characterized by dense deployments, millimeter-wave communications, and dynamic beamforming, the need for scalable simulation tools becomes increasingly critical. These tools must support efficient evaluation of key performance metrics such as coverage and radio-frequency electromagnetic field (RF-EMF) exposure, inform network design decisions, and ensure compliance with safety regulations. Moreover, base station (BS) placement is a crucial task in the network design, where satisfying coverage requirements is essential. To address these, based on our previous work, we first propose a conditional generative adversarial network (cGAN) that predicts location specific received signal strength (RSS), and EMF exposure simultaneously from the network topology, as images. As a network designing application, we propose a Deep Q Network (DQN) framework, using the trained cGAN, for optimal base station (BS) deployment in the network. Compared to conventional ray tracing simulations, the proposed cGAN reduces inference and deployment time from several hours to seconds. Unlike a standalone cGAN, which provides static performance maps, the proposed GAN-DQN framework enables sequential decision making under coverage and exposure constraints, learning effective deployment strategies that directly solve the BS placement problem. Thus making it well suited for real time design and adaptation in dynamic scenarios in order to satisfy pre defined network specific heterogeneous performance goals.
