OpenAirInterface is constantly evolving and you are welcome to contribute to its development.

OpenAirInterface Latest Releases

The current state of the RAN (develop and master branches) and the EPC is available at OAI Feature Sets.

OpenAirInterface Roadmap / Work in progress

The main phases are as follows:

  • Phase 1: "noS1" 5G-NR (with pre-configured gNB and OAI UE, no core network)
  • Phase 2: E-UTRA - NR dual connectivity (NSA architecture option 3x, with 4G CN) with COTS UE, ETA Q2-2020
  • Phase 3: StandAlone (with 5G CN) with COTS UE, ETA Q4-2020

As intermediate steps to reach these goals, we can mention:

  • Full DL Transmission (ETA June 2020)
    • Complete validation of DL-HARQ procedures
    • Integration with higher layers to inject real traffic
  • Full UL Transmission (ETA July 2020)
  • Further Improvements (ETA Q3-2020)
    • gNB: replace dummy scheduler with advanced scheduler
      • support for multiple users, beamforming
    • PHY: PTRS, multiple DMRS for PDSCH and PUSCH
    • UE: Completion of random access procedure
    • Support for Beamforming (mainly FR2)
      • Multiple SSBs and RACH occasions
      • RRC config and MAC scheduling of CSI-RS
      • UE measurements of CSI-RS and feedback reporting
      • RRC config and MAC handling of TCI states
    • Support for MIMO
  • for SA Mode (ETA Q4-2020)
    • RRC
    • SDAP
    • N2/N3 interface
