Abstract
The growing integration of artificial intelligence (AI) into wireless communication systems is driving a shift toward semantic communication, an emerging paradigm that prioritizes the exchange of meaning over raw data. However, semantic communication systems face major challenges when deployed across diverse and unseen domains due to variations in language, context, and channel conditions. This survey provides a comprehensive overview of Domain Generalization (DG) as a key enabler for improving the robustness and adaptability of AI-enabled semantic communication. We explore the types of domain shifts and review the latest DG techniques applicable to semantic communication. Additionally, the paper discusses architectural considerations and real world applications across varied wireless scenarios. Unlike prior works, this survey brings together DG strategies specifically within the context of semantic communication, identifying open challenges and future research directions such as scalable adaptation, resource efficient deployment, and resilience in dynamic environments. It aims to serve as a timely resource for researchers and practitioners working to develop reliable, generalizable communication systems for next generation networks.

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 it
