无线地图(RMs)提供基于位置的路径损耗估计,是实现6G网络主动、环境感知通信的基础。然而,现有基于深度学习的RM构建方法通常将动态环境建模为一系列独立的静态快照,忽略了由动态实体运动引起的信号传播变化的时间连续性。为解决这一问题,我们提出时空无线地图预测任务,即从历史观测中预测未来一系列地图序列。该预测方法的一大障碍是缺乏捕捉环境持续演化的数据集。为此,我们引入RadioMapMotion,这是首个基于物理一致车辆轨迹生成的大规模公开连续无线地图序列数据集。作为该任务的基线,我们提出RadioLSTM,一种基于卷积长短期记忆(ConvLSTM)的UNet架构,专为多步序列预测设计。实验评估表明,RadioLSTM在预测准确率和结构保真度方面均优于代表性基线方法。此外,该模型推理延迟低,显示出其在实时网络操作中的潜力。项目代码将在论文接收后公开于:https://github.com/UNIC-Lab/RadioMapMotion。
原文摘要 · Abstract (English)
Radio maps (RMs), which provide location-based pathloss estimations, are fundamental to enabling proactive, environment-aware communication in 6G networks. However, existing deep learning-based methods for RM construction often model dynamic environments as a series of independent static snapshots, thereby omitting the temporal continuity inherent in signal propagation changes caused by the motion of dynamic entities. To address this limitation, we propose the task of spatio-temporal RM prediction, which involves forecasting a sequence of future maps from historical observations. A key barrier to this predictive approach has been the lack of datasets capturing continuous environmental evolution. To fill this gap, we introduce RadioMapMotion, the first large-scale public dataset of continuous RM sequences generated from physically consistent vehicle trajectories. As a baseline for this task, we propose RadioLSTM, a UNet architecture based on Convolutional Long Short-Term Memory (ConvLSTM) and designed for multi-step sequence forecasting. Experimental evaluations show that RadioLSTM achieves higher prediction accuracy and structural fidelity compared to representative baseline methods. Furthermore, the model exhibits a low inference latency, indicating its potential suitability for real-time network operations. Our project will be publicly released at: https://github.com/UNIC-Lab/RadioMapMotion upon paper acceptance.
