Resource Scheduling for eMBB and URLLC Multiplexing in NOMA-Based VANETs: A Dual Time-Scale Approach
Bibliographic record
Abstract
Enhanced mobile broadband (eMBB) and ultra-reliable low-latency communication (URLLC) are two critical services in vehicular networks. However, the presence of both services creates a difficult resource allocation problem due to their heterogeneous requirements. To address the challenge of simultaneously providing eMBB and URLLC services in vehicular networks, we propose a resource allocation approach that maximizes eMBB rate while ensuring that both URLLC latency and reliability requirements are satisfied. Our approach utilizes non-orthogonal multiple access (NOMA) technology, where the resource for eMBB services is allocated by slot and the traffic of URLLC service is accommodated using mini-slots. To solve this dual time-scale problem, we employ a dual decomposition and sub-gradient method to solve the power allocation and resource block assignment of eMBB services, while the Vogel's approximation method (VAM) and modified distribution method (MODI) are proposed to solve the URLLC resource allocation problem. Additionally, we present two low-complexity heuristic algorithms for the URLLC sub-problem. Simulation results indicate that our proposed approach surpasses baseline methods in terms of both eMBB rate and fairness.

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.
