Abstract
Efficient allocation of resources (i.e., physical resource blocks (PRBs), transmit power) for remote radio heads (RRHs) in the fifth generation (5G) cloud radio access network (C-RAN) is crucial for the mobile network operators (MNOs) to support different use cases with diverse quality of service (QoS) requirements. In this paper, we study the resource allocation of enhanced mobile broadband (eMBB) and ultra-reliable lowlatency communications (URLLC) network slices in a 5G C-RAN. We formulate the resource allocation problem as a mixedinteger nonlinear program. We address the isolation between eMBB and URLLC network slices and the uncertainty in the traffic load by using the chance constraint. We consider short packet transmission to enable URLLC data transmission with low latency and high reliability. We propose an algorithm based on penalized successive convex approximation to determine a suboptimal solution of the formulated problem. The proposed algorithm has a polynomial time complexity. Simulation results show that the proposed algorithm on average achieves 30% higher throughput when compared with a baseline scheme that only optimizes the transmit power of users.

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
