  • v2.3.0

    8bf6d5d7 · Merge branch 'integration_2025_w27' into 'develop' · 
    Release v2.3.0

General new features and improvements (both RAN and UE):
- Preliminary support for RedCap UEs
- Support for NTN LEO scenarios including SIB19 and channel emulation (see
  doc/RUNMODEM.md)
- VRTSIM: new shared memory realtime radio (see develop/radio/vrtsim/README.md)
- Support for TDD pattern 2
- Support for long PRACH
- Support for SIB2
- Add unit tests using ctest (see doc/UnitTests.md)

Stability and bug fixes:
- Improve various procedures (e.g., RRC reestablishment, RRC Reject, ...)
- Add improvements for ImScope
- Bugfixes in the entire stack (e.g., #803, #805, #810, #812, #818, #852, #878,
  #884, #890, #895, #901, #907, #932, #939 ...)
- Documentation updates
- And many other small fixes, like memory leaks, crashes, ...

RAN changes (gNB/CU/CU-CP/CU-UP/DU/DU-high/DU-low):
- Stability and performance improvements when running with 4-layer DL MIMO
- Stability and performance improvements when running with 2-layer UL MIMO
- Interoperability testing with Metanoia Jura and Foxconn RUs
- Support of O-RAN 7.2 M-plane (Start-up procedure including configuration
  management, see also doc/ORAN_FHI7.2_Tutorial.md)
- Upgrade OSC FHI (xran) from E to F release
- Refactoring of LDPC interface and performance improvements
- Support for nFAPI in all scenarios for FR1 (see doc/nfapi.md)
- Support at least 32 UEs concurrently
- Improve robustness when running in split modes (F1, E1)
- Add basic support for beam management in FR2
- Add support for O1 on DU (see also https://gitlab.eurecom.fr/oai/o1-adapter)
- E2 agent: Support for multiple E2SM-RC report service styles

nrUE changes:
- Refactoring of threading towards better code and performance
- Add or rework various procedures (e.g., RA with C-RNTI, Going to Idle, RA, ...)
- Refactor and extend NAS implementation (e.g., Service Request, Registration
  Request, Service Acept, Service Reject, ...)
- Support for continuous frequency offset compensation
- Reduce minimum RX-to-TX time to 3

Regression:
- Multiple BWPs do not work reliably on gNB; use tag 2025.w17
