Abstract
Abstract In Part I of this paper, the ergodic information rate is derived for an orthogonal frequency‐division multiplexing access (OFDMA) uplink with cooperative relaying in the presence of frequency offsets. In this part, the outage information rate of the system is analysed. Both amplify‐and‐forward (AF) and decode‐and‐forward (DF) relays are considered. Each node can play the roles of the source node and the relay, simultaneously, at different subcarriers. Both the outage information rate and the diversity gain are derived for the interference‐limited environment. Numerical results illustrate the superior performance of the proposed cooperative scheme over conventional transmission (without relaying) with regard to outage information rate.

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
