Cloud radio access networks (C-RAN) in mobile cloud computing systems
Bibliographic record
Abstract
Cloud computing will have profound impacts on wireless networks. On one hand, the integration of cloud computing into the mobile environment enables mobile cloud computing (MCC) systems; on the other hand, the powerful computing platforms in the cloud for radio access networks lead to a novel concept of cloud radio access networks (C-RAN). In this paper, we study the topology configuration and rate allocation problem in C-RAN with the objective of optimizing the end-to-end performance of MCC users in next generation wireless networks. An intrinsic issue related to such system is that only sub-optimal decisions can be made due to the fact that the channel state information is outdated. We employ a decision-theoretic framework to tackle this issue, and maximize the system throughput with constraints on the response latency experienced by each MCC user. 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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
