Abstract
In this paper, we jointly consider cloud radio access networks (C-RAN) and mobile cloud computing (MCC) in a holistic framework. In particular, we study how to dynamically operate C-RAN to enhance the end-to-end performance of MCC services in next-generation wireless networks. An intrinsic challenge in such a system is that channel state information (CSI) is outdated. With delayed CSI, only suboptimal C-RAN operations can be made if deterministic optimization techniques are applied directly. We formulate the topology configuration and rate-allocation problem with delayed CSI under a stochastic optimization framework. Such a framework maximizes MCC services' sum throughput with constraints on the response latency experienced by each MCC user. We propose an optimal policy for the stochastic optimization problem, which has the advantage of low computation cost. Offline and online algorithms are developed based on the optimal policy. Using simulation results, we show that, with the emergence of MCC and C-RAN technologies, the design and operation of future mobile wireless networks can be significantly affected by cloud computing, and the proposed scheme is capable of achieving substantial performance gains over existing schemes.

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
