Abstract

fetched live from OpenAlex

Small cell is a growing technology that enables Mobile Network Operators (MNOs) to deploy sites in strategic locations offering smaller coverage with higher capacities, using licensed and unlicensed wireless spectrum. The most problematic and restrictive element carriers face when deploying a small cell network is backhauling. Finding a site for deploying a small cell can be a painstaking process. Beam management is a procedure that correctly selects the beams to overcome strong path loss attenuation. In this paper, a beam tracking solution for sub-6 GHz is proposed. Together with the path-loss information of all the serving hub beams, its serving hub shares this path-loss map with the other co-located hubs at the same cell/site. The remote backhaul module uses the sum-utility-based algorithm to pick the hub beam that maximizes the sum utility of the link.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
