Researchers have developed a new trajectory-aware paradigm for radio map estimation (RME) to address the distribution shift between independently and identically distributed (i.i.d.) training data and real-world sequential UAV measurements. The proposed Stochastic-Triggered Trajectory-Based Sampling (ST-TBS) method aims to improve model generalization by aligning training and deployment sampling distributions. Experiments show that ST-TBS significantly reduces the root-mean-square error (RMSE) compared to traditional random sampling methods, particularly under trajectory-based observations. AI
