Public data dictionary

tb_level

One row represents one validated formal new transport block (TB). The table contains run/pair/controller/UE identity, monotonic transmit and feedback timestamps, MCS/TBS/PRB/layer observations, first-round ACK/NACK/DTX outcome, HARQ result, link-setting command and offline calibrated quantities. source_file identifies the sanitized CSV shard from which the row was assembled.

The p3 split contains the 20→16 step experiments; the p4 split contains the 22→16→22→16 path experiments. run_id and new_tb_id identify a TB in a run; pair_id links the Frontier and OLLA halves of a matched experiment.

Summary tables

• run_summary: one row per formal half-run, including first-round BLER, goodput, mean MCS, feedback/decision delay, recovery and validation counts.
• change_summary: one row per profile change event, including direction, post-change BLER, recovery blocks and right-censoring.
• pair_metrics: one row per matched pair. Every diff_* column is Frontier minus OLLA.
• metric_summary: paired mean, 95% confidence interval and paired effect size by campaign and metric.

Calibration tables

• p1_calibration_points: UE03 point/chunk BLER observations used for fitting.
• p1_calibration_curves: monotone logistic crossing estimates and confidence intervals for MCS 14–26.
• p1_mcs_table: compact MCS-to-command-crossing lookup.
• p1_fit_checks: coverage and fit acceptance checks for each MCS.
• p2_evidence: selected UE/MCS/setting evidence rows.
• p2_crossings: raw/isotonic sequences and crossing type; left_censored or right_censored means the crossing was outside the observed setting range.
• p2_checks: overall three-UE freeze and boundary-coverage checks.

Outcome conventions

first_round_ack=1 means the first transmission was acknowledged. A first-round failure is NACK or DTX. link_setting_db is the relative OAI software TX attenuation command; larger values represent a worse effective transmit setting in this experiment. Columns ending in _derived are offline calculations, not direct hardware readbacks.
