Unified and Distributed QoS-Driven Cell Association Algorithms in\n Heterogeneous Networks
Bibliographic record
Abstract
This paper addresses the cell association problem in the downlink of a\nmulti-tier heterogeneous network (HetNet), where base stations (BSs) have\nfinite number of resource blocks (RBs) available to distribute among their\nassociated users. Two problems are defined and treated in this paper: sum\nutility of long term rate maximization with long term rate quality of service\n(QoS) constraints, and global outage probability minimization with outage QoS\nconstraints. The first problem is well-suited for low mobility environments,\nwhile the second problem provides a framework to deal with environments with\nfast fading. The defined optimization problems in this paper are solved in two\nphases: cell association phase followed by the optional RB distribution phase.\nWe show that the cell association phase of both problems have the same\nstructure. Based on this similarity, we propose a unified distributed algorithm\nwith low levels of message passing to for the cell association phase. This\ndistributed algorithm is derived by relaxing the association constraints and\nusing Lagrange dual decomposition method. In the RB distribution phase, the\nremaining RBs after the cell association phase are distributed among the users.\nSimulation results show the superiority of our distributed cell association\nscheme compared to schemes that are based on maximum signal to interference\nplus noise ratio (SINR).\n

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.
