Digital Twin Channel-Aided CSI Prediction: A Region-Adaptive Environment-Based Subspace Extraction Approach With Channel Similarity

Low-overhead channel state information (CSI) acquisition is critical for multiple-input multiple-output (MIMO) systems. Digital twin channel (DTC), which reconstructs the 3D physical environment using environmental information, is a promising low-overhead CSI acquisition paradigm. However, most existing works use raw s...

PLM-Based Two-Stage Semantic Encoding for Task-Oriented Semantic Communication on the Fly

Semantic communication (SemCom) moves beyond bit-level transmission by conveying semantic features, and task-oriented communication (TOC) further targets the transmission of task-relevant features to improve communication efficiency. However, existing TOC schemes still rely on high-dimensional deep learning (DL)-based...
