Abstract
Multi-packet reception (MPR), in which a receiver can decode multiple simultaneous transmissions, significantly improves the uplink throughput of wireless local area networks (WLANs). However, the medium access control (MAC) layer must be redesigned to encourage, and not avoid, simultaneous transmissions. Asynchronous MPR MAC protocols, in which nodes independently access the channel so long as the number of ongoing transmissions is less than a threshold, are promising solutions for enabling MPR in IEEE 802.11-based WLANs. In this paper, we highlight the problem of acknowledgment (ACK) delays that arises in asynchronous MPR when multiple nodes transmit in succession without the channel becoming idle. We propose a novel asynchronous MAC protocol that reduces the ACK delays, increases throughput, and retains the distributed nature of the 802.11 distributed coordination function (DCF). An accurate renewal theoretic fixed-point analysis that leads to general analytical expressions for the saturation throughput is also developed.

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
