Simultaneous Cellular and D2D Communications Exploiting Cooperative Uplink NOMA
Bibliographic record
Abstract
A novel device-to-device (D2D) aided uplink transmission scheme exploiting non-orthogonal multiple access (termed as D2D-UNOMA) is proposed and investigated. In D2D-UNOMA, two similar gain near users (NUs) and a far user (FU) can transmit their information to the base station (BS) in two time slots. The NUs can directly communicate with the BS, whereas the FU requires assistance of one of the NUs to facilitate the communication. In addition, as part of D2D communications, one of the NUs can transmit to the other NU in the first phase, whereas the FU can transmit to a NU in the second phase. The performance of D2D-UNOMA is studied in terms of ergodic rate along with analytical formulation. Through numerical results, it is demonstrated that the proposed D2D-UNOMA can ameliorate the ergodic sum rate significantly compared to the conventional orthogonal multiple access.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
