Uplink power allocation schemes for heterogeneous cellular networks
Bibliographic record
Abstract
With the increasing number of small cell nodes, the power consumption in Heterogeneous Networks (HetNets) has increased significantly resulting in problems such as higher interference among nodes, higher outage, and decreased capacity. In this paper, we propose various power allocation schemes where we allocate power among the heterogeneous user equipments. First, we propose a scheme which jointly minimizes outage probability and total power consumption in the network. Second, we devise a scheme which jointly maximizes total throughput and minimizes total power consumption. These schemes formulate multi-objective optimization problems, which are then solved using weighted sum approach. Third, we investigate a scheme to maximize energy efficiency defined as system throughput achieved per unit power consumption. Simulation results clarify the need for tradeoff among various performance parameters in practice based on device's remaining battery capacity, system outage target and quality of service (QoS) requirement in terms of signal-to-interference-plus-noise ratio (SINR). The results also show that the proposed power allocation schemes are highly efficient in attaining such tradeoffs.

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.
