Coverage Analysis of Max-SIR Cell Association in HetNets Under Nakagami Fading
Bibliographic record
Abstract
For maximum signal-to-interference (SIR) ratio cell association, we investigate the coverage probability of HetNets under Nakagami fading. Prompting serious analytical complexities, Nakagami-type fading, however, describes several important wireless environments of 4G/5G standards, including multi-antenna systems. Adopting tools of stochastic geometry, we provide a number of closed-form approximations for the coverage probability, which have been missing in the literature. Our analysis covers integer and noninteger Nakagami, Rician, and κ - μ shadowed fading distributions, and also multiuser zero-forcing beamforming in the downlink. Furthermore, the analysis of this paper incorporates the traits of AWGN, partially loaded systems, and bounded path-loss function, which are often overlooked in studying HetNets. The result are easy to compute, preserve acceptable accuracy, and explicitly demonstrate the impact of fading parameters, density of BSs, SIR thresholds, loads, and path-loss model. We reveal important insights regarding the practice of densification in conjunction with SIR thresholds, BS loads, and path-loss model. It is observed that from a network-level perspective, a bounded path-loss model can be grasped via a reduction of the density of BSs granting association as well as interference, for which the former becomes dominant in dense configurations.

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.
