Abstract
In this letter, we investigate the performance of a full-duplex (FD) cooperative rate splitting multiple access (C-RSMA) scheme in a downlink multiple-input single-output (MISO) system consisting of one base station (BS) that serves two users simultaneously. With the objective of maximizing the minimum achievable rate, we jointly optimize the BS precoding vectors, the common-stream split and the device-to-device transmit power subject to the power budget of both the BS and the relay device. As the entire problem is non-convex, we propose a low complexity algorithm based on the successive convex approximation (SCA) technique. Simulation results demonstrated that the FD C-RSMA can achieve a higher minimum achievable rate than some baseline schemes, including the FD cooperative non-orthogonal multiple access (FD C-NOMA), the half-duplex (HD) C-RSMA, RSMA and NOMA.

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
