5G indoor Time of Arrival (TOA) and Reference Signal Received Power (RSRP) dataset

This dataset contains open and reproducible measurements collected during 5G NR indoor positioning experiments performed within two controlled testbeds: the UPC corridor (Barcelona) and the Escola Ginebró workshop (Llinars del Vallès). The measurements were obtained using an OpenAirInterface (OAI)-based software-defined radio (SDR) setup operating at 3.5 GHz (NR FR1), with configurable bandwidth (20 MHz) and subcarrier spacing (30 kHz). Each dataset provides Received Signal Reference Power (RSRP) and Time-of-Arrival (ToA) values recorded at multiple known receiver positions, together with the spatial coordinates of the transmitting gNBs and metadata describing the physical environment. Two test scenarios are included: Scenario A – UPC corridor: linear, reflective indoor hallway with four gNBs, 32 m × 2.5 m measurement grid, 23 positions × 10 repetitions. Scenario B – Escola Ginebró workshop: open rectangular workspace with three gNBs, 10 m × 12 m grid, 15 positions × 10 repetitions. All files are provided in CSV format, containing position coordinates (x, y, z [m]), gNB identifiers, and corresponding RSRP values (dBm).
