Abstract
This paper tackles the joint problem of user association, channel assignment, UAV placement, and transmit power allocation in cell-free wireless networks. Each user can either be directly connected to a ground base station (GBS) or through UAVs acting as relays. To address this, we formulate the problem mathematically as a mixed-integer non-convex program, to minimize the number of deployed UAVs under data rate requirements and coverage constraints. Since the problem is NP -hard, we propose a model-free algorithm utilizing the deep deterministic policy gradient method to handle UAV deployment and positioning within a continuous space domain. We also propose efficient heuristic and meta-heuristic algorithms for comparison purposes. Simulation results demonstrate the benefits of the cell-free concept in satisfying users and improving the performance of UAV-assisted wireless networks. They also validate the effectiveness of the proposed algorithms in minimizing the required number of deployed UAVs to meet stringent user requirements.

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 it
