A delay bounded approach for streaming services in CDMA cellular networks
Bibliographic record
Abstract
This paper considers the design of resource management schemes for cellular networks where mobile users are interested in receiving streaming media flows, and the cell utilizes a Discrete Sequence Code Division Multiple Access (DS-CDMA) air interface. Due to the relatively high data rate requirement of the streaming service, and the limiting effect of the multiple access interference (MAI) in CDMA networks, the cell may undergo overload conditions as the wireless channel path losses increase for any subset of users. In response, the base station is expected to delay, or perhaps forcibly terminate, some traffic streams.To achieve acceptable performance, we examine the use of a novel admission control scheme that takes user mobility into consideration. The utilized scheme admits a traffic stream only if the estimated cell overload probability after a prescribed prediction interval does not exceed a specified threshold value. As well, we devise a packet scheduling algorithm that aims at minimizing the number of forced terminations of connections that exceed specified delay bounds. Performance of the proposed admission control scheme in conjunction with the devised scheduling procedure is analyzed using simulation. The obtained results show significant improvement of using the proposed methods over methods that don't take user mobility into account.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
