Abstract
Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (EUTRAN) deals with high uplink and downlink throughput. The Proportional Fair (PF) Medium Access Control (MAC) scheduler offered a good balance between allocated resources and fairness among the User Equipment (UE) in comparison with other schedulers. In the PF scheduler, at each cycle of resource allocation, a feedback mechanism ensures that operational resource requirements are met while maintaining a degree of fairness among the UE. We analyze the effect of feedback Transmission Time Interval (TTI) delay on two typical EUTRAN networks, in terms of Key Performance Indicators (KPIs). One network is referred to as EUTRAN LTE and the other as EUTRAN LTE-A, which fulfils high throughput requirement. We evaluate the performance of the PF MAC scheduler for both networks under varying feedback delay in TTI. Simulated results show that the delay in TTI affects the performance of resource allocation in terms of throughput, fairness, and spectral efficiency. Feedback delay improves network performance by compensating effect of imperfect channel condition.

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
