Abstract
Abstract Unmanned aerial vehicle (UAV) relay system has received significant attention in future wireless communications. In this article, the ergodic sum rate of a multisource multidestination UAV relaying is investigated. Here, an UAV with multiple antennas is deployed as an aerial relay using threshold‐based decode‐and‐forward protocol to assist signal transmission from multiple sources to their intended destinations simultaneously. By considering the effect of path loss, we first obtain the output signal‐to‐interference‐plus‐noise ratio expression for the considered system. Then, we propose a statistical channel state information based beamforming (SCSI‐BF) scheme to maximize the system ergodic sum rate, where both of the uplink and downlink channels are subject to correlated Rayleigh fading. Furthermore, we derive the analytical expression for the ergodic sum rate of the considered system with the SCSI‐BF scheme. Finally, numerical results are given to demonstrate the superiority of the SCSI‐BF scheme and the validity of the theoretical analysis, and show the impact of various parameters on the system performance.

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
