Abstract
With increasing emphasis on incorporating energy awareness in future communication systems, it is desirable to explore power-efficient resource allocation techniques. Therefore, in this paper, we consider the sum-power minimization of base stations (BSs) and users in a full-duplex (FD) multiple-input multiple-output multi-cell system. In particular, we assume that BSs operating in FD transmission mode serve multiple FD mobile users at the same time over the same frequency band. To guarantee a certain quality of service (QoS), we enforce the maintenance of a minimum signal-to-interference-plus-noise ratio for each user. Concerning these design constraints together with realistic FD self-interference models, we investigate the transmit and receive beamforming designs that minimize the joint transmission power of BSs and users. However, the resulting optimization problem is NP-hard. We therefore divide this optimization problem into separate receive and transmit beamforming design steps, which can be solved iteratively. In addition, the non-convex precoder design problem is posed as a difference of convex function programming, which can be efficiently solved via successive convex approximation. In order to account for practical aspects in our design, we also take into account imperfect channel state information by way of stochastic and bounded uncertainties. Numerical results suggest that the FD systems generally outperform the half-duplex ones under a wide range of QoS constraints and transceiver distortions.

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
