The repository consists of the downlink control information (DCI) messages collected in a commercial three-sector eNB of the SFR mobile network operator (MNO) in the city center of Rennes, France. We performed one-week measurement campaign between Saturday, February 19, and Friday, February 25, 2022. The MNO uses four different frequency bands in the monitored sector:
- EARFCN 6300: 800 MHz band and a bandwidth of 10 MHz
- EARFCN 1501: 1800 MHZ band and a bandwidth of 20 MHz
- EARFCN 78: 2100 MHZ band and a bandwidth of 15 MHz
- EARFCN 2825: 2600 MHZ band and a bandwidth of 15 MHz
For each day and each frequency band, the data is stored in a CSV file named TraceDATE_sfr_earfcnXX.csv, where DATE represents the date in yyyymmdd format and XX represents the EARFCN of the frequency band. In the CSV file, each row represents a DCI message, and the columns include the following features:
- Time: Unix timestamp in milliseconds
- rnti: RNTI associated with the DCI
- SFN: system frame number
- format: DCI format (0: format0, 2: format1A, 6: format2)
- preamble: random access preamble
- ta: first timing advance
- nb_TB: number of enabled transport blocks
- MCSi_1: MCS index of the first transport block (-2: TB is disabled )
- MCSi_2: MCS index of the second transport block (-2: TB is disabled )
- TBS_1: TBS of first transport block (-2: TB is disabled )
- TBS_2: TBS of second transport block (-2: TB is disabled )
- nb_PRB: number of allocated PRBs
- connection_id: unique connection identifier
Note: the first values of the connection identifier are reserved: 1 for RA-RNTI, 2 for P-RNTI, and 3 for SI-RNTI. The other values are used to identify user connections (C-RNTI).
