Cross-Modal Semantic Transmission Strategy for Mobile Scenarios
Bibliographic record
Abstract
To fulfill the demands of emerging multi-modal services, the cross-modal semantic communication paradigm comes into being. It fully utilizes potential semantic correlations among modalities to address polysemy and ambiguity issues, enhancing transmission reliability. However, applying cross-modal semantic communication in resource-constrained mobile scenarios introduces new challenges, including radio spectrum bandwidth limitations and fluctuations for the transmitter, and computing resource constraints for the receiver, which leads to potential transmission failures. To bridge this gap, this paper proposes a cross-modal semantic transmission strategy for mobile scenarios (MobileCMST). We first construct the framework for MobileCMST. Within this framework, a semantic encoder is designed to achieve redundancy elimination for visual and haptic signals. Then, a semantic delivery approach is developed to cope with bandwidth fluctuations and multipath fading channels. Finally, an efficient semantic decoder based on a visual-haptic semantic-integrated diffusion model is proposed. It employs the Mamba backbone to reconstruct high-quality signals with lightweight computational complexity. Extensive experiments demonstrate the excellent performance of the proposed MobileCMST strategy in resource-constrained mobile scenarios.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
