Colosseum O-RAN ColORAN Dataset

This repository contains the dataset for the paper M. Polese, L. Bonati, S. D'Oro, S. Basagni, T. Melodia, "ColO-RAN: Developing Machine Learning-based xApps for Open RAN Closed-loop Control on Programmable Experimental Platforms," IEEE Transactions on Mobile Computing, pp. 1-14, July 2022. Please cite the paper if you plan to use it in your publication.

This work was partially supported by the U.S. National Science Foundation under Grants CNS-1923789 and NSF CNS-1925601, and the U.S. Office of Naval Research under Grant N00014-20-1-2132.

Experiment setup

  • Number of Base Stations (BSs): 7
    • Nodes: 1, 8, 15, 22, 29, 36, 43
  • Channel bandwidth: 10 MHz (50 Physical Resource Blocks (PRBs))
  • Number of slices for each BS: 3
  • Scheduling policies available to each slice:
    • Policy 0: Round-robin (RR)
    • Policy 1: Waterfilling (WF)
    • Policy 2: Proportionally fair (PF)
  • Number of User Equipments (UEs): 42
  • Radio Frequency (RF) scenario setup (Colosseum Rome scenario):
    • Medium: UEs uniformly distributed within 50 m of each BS
  • UE Mobility: static
  • Traffic classes:
    • eMBB: Constant bitrate traffic (4 Mbps per UE)
    • MTC: Poisson traffic (30 pkt/s of 125 bytes per UE)
    • URLLC: Poisson traffic (10 pkt/s of 125 bytes per UE)
  • UEs belong to different traffic classes:
    • eMBB UEs (slice 0): 3, 6, 10, 13, 17, 20, 24, 27, 31, 34, 38, 41, 45, 48
    • MTC UEs (slice 1): 4, 7, 11, 14, 18, 21, 25, 28, 32, 35, 39, 42, 46, 49
    • URLLC UEs (slice 2): 2, 5, 9, 12, 16, 19, 23, 26, 30, 33, 37, 40, 44, 47
  • UEs are divided per slice based on traffic types:
    • Slice 0: eMBB UEs
    • Slice 1: MTC UEs
    • Slice 2: URLLC UEs

Training configurations

For each scheduling policy (directories sched0, sched1, sched2), the Resource Block Group (RBG) allocations for each slice are as follows.
