Abstract
Device-to-device (D2D) communications in cellular networks are considered a promising technology for improving network throughput, spectrum efficiency, and transmission delay. In this paper, the Power Emission Density (PED)-based interference modeling method is applied to explore proper network settings for enabling multiple concurrent D2D pairs in a sector-partitioned cell. With the constraint of the Signal-to-Interference Ratio (SIR) requirements for both the macro-cell and D2D communications, an exclusive region-based analytical model is proposed to obtain the guard distances from a D2D user to the base station, to the transmitting cellular user, and to other communicating D2D pairs, respectively, when the uplink resource is reused. With these guard distances, the bounds of the maximum throughput improvement provided by D2D communications are then derived for different sector-based resource allocation schemes. Extensive simulations are conducted to verify our analytical results. The new results obtained in this work can provide useful guidelines for the deployment of future cellular networks with underlaying D2D communications.

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
