Multitimescale Control and Communications With Deep Reinforcement Learning—Part I: Communication-Aware Vehicle Control
Bibliographic record
Abstract
An intelligent decision-making system enabled by vehicle-to-everything (V2X) communications is essential to achieve safe and efficient autonomous driving (AD), where two types of decisions have to be made at different timescales, i.e., vehicle control and radio resource allocation (RRA) decisions. The interplay between RRA and vehicle control necessitates their collaborative design. In this two-part paper (Part I and Part II), taking platoon control (PC) as an example use case, we propose a joint optimization framework of multitimescale control and communications (MTCCs) MTCCs based on deep reinforcement learning (DRL). In this article (Part I), we first decompose the problem into a communication-aware DRL-based PC subproblem and a control-aware DRL-based RRA subproblem. Then, we focus on the PC subproblem assuming an RRA policy is given, and propose the MTCC- PC algorithm to learn an efficient PC policy. To improve the PC performance under random observation delay, the PC state space is augmented with the observation delay and PC action history. Moreover, the reward function with respect to the augmented state is defined to construct an augmented state Markov decision process (MDP). It is proved that the optimal policy for the augmented state MDP is optimal for the original PC problem with observation delay. Different from most existing works on communication-aware control, the MTCC- PC algorithm is trained in a delayed environment generated by the fine-grained embedded simulation of cellular vehicle-to-everything communications rather than by a simple stochastic delay model. Finally, experiments are performed to compare the performance of MTCC- PC with those of the baseline DRL algorithms.

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.
