Abstract
Drone as a base station can provide wireless services in a variety of situations. In this letter, we employ a uniform linear array (ULA) to produce a directional beam to increase the quality of service (QoS) of users in the downlink of cellular networks. Due to the strict power limitations of a drone base station (DBS), we envision a single radio frequency (RF) chain architecture. A beamforming design methodology in an unknown environment is presented over a mmWave channel with the aim of maximizing the number of covered users while taking into account the human body blockage effects. Regarding the ambiguity of the environment, we model the problem of finding the optimal beam direction as a multi-armed bandit (MAB). Due to its fast convergence property, Thompson sampling (TS) is used for solving the MAB problem. Simulation results show that the DBS is able to find the optimal beam angle in only tens of iterations.

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
