Abstract
Code-expanded Random Access (CeRA) is a promising technique for supporting\nmMTC in cellular IoT networks.\n However, its potentiality is limited by code ambiguity, which results from\nthe inference of a larger number of codewords than those actually transmitted.\n In this letter, we propose a random access scheme to alleviate this problem\nby allowing devices to select the preambles to be transmitted considering a\nq-ary code with maximum average distance.\n Moreover, a CeRA decoding approach based on hypergraphs is proposed and an\nanalytical model is derived.\n Numerical results show that the proposed scheme significantly increases the\nprobability of successful channel access as well as resource utilization.\n

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
