Implication

Simulation analysis demonstrates up to 87.5% delay reduction using semantic compression in Open RAN non-terrestrial networks, indicating efficient satellite-terrestrial 6G connectivity.

Key Points

To develop and evaluate SEM-NTN, a semantic-aware Open RAN framework that optimizes bandwidth efficiency and reduces transmission latency in 6G non-terrestrial networks.
Engineered an Open RAN-enabled non-terrestrial network framework integrating AI-driven feature extraction, adaptive semantic compression, and dynamic resource allocation.
Conducted network simulations assessing transmission delay alongside AI task performance metrics under a 5ms delay constraint against a uniform compression baseline.
SEM-NTN decreased transmission delay by up to 87.5% compared to conventional transmission while maintaining AI inference accuracy near full-quality compression.
Semantic-aware compression achieved 84.6% mean Average Precision (mAP) and 77.6% mean Intersection over Union (mIoU) under a 5ms delay constraint, closely matching the uniform baseline (85% mAP, 78% mIoU).
