Uplink PUSCH IQ captures from six real 5G devices, recorded gNB-side on a
live OpenAirInterface 5G SA network. 600,000 records (100,000 per device),
every one captured on a single identical radio configuration.
Every record is a fixed 51 PRB uplink allocation — the full carrier width
(612 subcarriers, 18.36 MHz at 30 kHz SCS).
