Abstract
With its capability of supporting high data rate services in a short range, the ultra-wide band (UWB) technology is appealing for future wireless personal area networks (WPANs). However, the WPAN medium access control (MAC) protocol in IEEE 802.15.3 standard was originally designed for narrow band communication networks, and it is inherently inefficient for UWB networks. In this paper, we explore the unique characteristics of UWB communications and propose how to schedule concurrent transmissions in UWB networks, which can significantly improve efficiency and network capacity. Since the optimal scheduling problem for peer-to-peer concurrent transmissions is NP-hard, the induced computation load for solving the problem is not affordable to the network coordinator, commonly a normal UWB device with limited computation power and energy. We propose two simple heuristic scheduling algorithms with polynomial time complexity. Extensive simulations with random network topology demonstrate that, by allowing concurrent transmissions appropriately, the proposed scheduling algorithms can significantly increase the network 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 it
