v2.4.0
Release: v2.4.091e7030c · ·Release v2.4.0 General new features and improvements (both RAN and UE): - Rework LDPC BBdev/AAL interface and support both AMD T2/Intel vRAN Boost (VRB) 1 accelerators - Add a taps client for vrtsim real-time simulator - Add new RFemulator virtual radio driver to emulate radio (including noise generation) for gNB/UE standalone operation - RLC AM reception improvements for high-throughput scenarios (!3512) - Small NTN fixes (!3659, !3666, !3581, !3652) - Improvements to imScope Stability and bug fixes: - RFsimulator: fix concurrency problems during multi-client connection - USRP driver: support synchronization of USRP B200 - MAC scheduler improvements - General L1 improvements for efficiency and stability - Correct PRS bug and test in CI - Upgrade Ubuntu container images to Ubuntu 24.04 - All build system targets compile (`make/ninja all`) - Minor cleanup, harmonization, and performance improvements all over the stack - Simplify CI code RAN changes (gNB/CU/CU-CP/CU-UP/DU/DU-high/DU-low): - Support of N2 handover - Support of "UL-heavy" TDD patterns, e.g., DSUUU - Open Fronthaul M-plane: CM improvements, PM implementation, and additional v16.01 support - Improve interoperability with Nvidia Aerial L1 to support 2 layer UL - Add O-RAN OSC WLS library as FAPI transport and enable L1/L2 shared memory split - Implement FAPI Stop exchange - Improve interoperability with srsRAN_Project DU - Add new synchronized real-time data recording application (!3462) - Support for measurement gaps and general handover fixes - Support of RRC PDU session release procedure - Add CU-UP load tester - Correct BWP scheduling and support multiple BWPs per UE nrUE changes: - Support one additional PDU session (see !3486) - L3 measurements for A2 measurement reports - Support for type0 PDSCH frequency allocation - UE symbol based PDCCH receiver Regression or removals: - No known regressions - Unused L2 simulator code has been removed - Unused Benetel radio driver code (not FHI 7.2!) has been removed Configuration file changes: - `gNBs.[0].servingCellConfigCommon.[0].ra_ResponseWindow` is automatically computed and can be removed - `gNBs.[0].bwp_list` has been added (moved from entries in `gNBs.[0].servingCellConfigDedicated`) - `gNBs.[0].phaseTrackingRS` has been added (moved from entries in `gNBs.[0].servingCellConfigDedicated`) - `gNBs.[0].local_s_portc` and `gNBs.[0].remote_s_portc` have no effect and should be removed - `gNBs.[0].CSI_report_type` has been added - `MACRLCs.[0].ulsch_max_frame_inactivity` is automatically computed and can be removed - `MACRLCs.[0].local_n_portc` and `MACRLCs.[0].remote_n_portc` have no effect and should be removed - `MACRLCs.[0].stats_max_ue` has been added
