Fairness-Aware Beam Placement Scheduling for LEO Satellites
Bibliographic record
Abstract
One of the primary objectives of the next-generation communication systems is to establish ubiquitous coverage. In this regard, Low Earth Orbit (LEO) satellite networks have attracted significant attention as a promising technology to achieve global coverage. However, fairly and efficiently managing resource allocation, especially beam placement scheduling, poses a significant challenge due to the large number of ground terminals and the vast coverage of LEO satellites. To address this challenge, we model the beam placement scheduling as a problem of minimizing terminal payload at the LEO satellite while considering fairness among terminals. In our proposed solution, we divide the coverage area into segments and use the advantage actor-critic (A2C) to schedule beams within each segment. Our simulations demonstrate that our approach outperforms the greedy method in terms of both throughput and fairness while improving first-time access to the LEO satellite for terminals. Moreover, it outperforms round-robin (RR) scheduling in terms of throughput.

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.
