Abstract

fetched live from OpenAlex

This paper investigates the problem of initial beam alignment that is crucial to beam-based communications used in 5G and envisioned for 6G. Our proposed method includes a beam sweeping using a learned codebook, and a beam prediction by a categorization neural network (NN) based on the measurements from the sweeping. Different from the straightforward supervised learning for the optimal beam index, we first design a compact representation of the optimal beam to reduce the complexity of the NN. Then, we show that learning the single optimal beam index can be problematic for realistic scenarios, and propose to use a new probabilistic spatial power distribution as the output. We show that our method is better suited for future wireless generations and can provide various information related to beam management by simulations.

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. 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.
