Abstract
This letter proposes an orthogonal time frequency space (OTFS) modulation based non-orthogonal multiple access (NOMA) scheme for the coordinated direct and relay transmission system, where a source communicates directly with a nearby mobile user, and serves a distant user with high-mobility relying on the relaying assistance. However, the coexistence of signal superposition coding and multi-domain transformation presents a challenge in measuring the performance of OTFS-based NOMA from a theoretical perspective. To accurately evaluate the system performance of the proposed scheme, we derive the closed-form expressions for the outage probability and outage sum rate using the inversion formula and characteristic function under both perfect SIC and imperfect SIC. Numerical results verify the performance superiority and the effectiveness of the proposed scheme.

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
