Randomized trial investigates a new communication method for enhancing task performance in autonomous vehicles, suggesting improved efficiency.

Key Points

This research aims to develop a unified framework for hierarchical transmission and online scheduling to improve communication in the Internet of Vehicles.
Integrates hierarchical transmission layers for latency-critical and perception-intensive tasks.
Formulates an online scheduling problem that considers Age of Information (AoI) and Channel State Information (CSI).
Evaluates resource utilization and task robustness under strict physical-budget constraints.
Achieves a 78% reduction in global semantic staleness with hierarchical transmission.
Shows nearly 47 percentage points improvement in task-proxy detection rate at 0 dB SNR compared to the uncoded baseline.
Demonstrates significant task robustness enhancement using joint source-channel coding over conventional schemes.
