Add `num_phys` to `nvipc_params_t` so the number of configured PHYs
flows from `gnb_config.c` down into the nvIPC layer without hardcoding.
`configure_nr_nfapi_vnf` now creates one `pnf_list` entry per PHY
(instead of a single hardcoded entry), and `epoll_recv_task` injects
one fake PARAM.RESPONSE per PHY so each cell triggers its own
CONFIG.REQUEST. `nr_param_resp_cb` picks up `config[p5_idx]` so the
correct per-cell MAC config is sent.
Incoming P5 responses from cuBB are dispatched using `msg->cell_id` as
`p5_idx` in `vnf_nr_handle_p4_p5_message()`, matching the per-cell
routing established for P7.
Single-cell behaviour is unchanged (`num_phys = 1`).

P7 send functions (oai_fapi_ul_tti_req, oai_fapi_ul_dci_req,
oai_fapi_tx_data_req, oai_fapi_dl_tti_req, oai_fapi_send_end_request)
now take a phy_id argument instead of a hardcoded value, resolving the
TODO FIXME stubs. The parameter is renamed from CC_id to phy_id to
reflect that it is a FAPI-layer identifier, not a MAC-layer concept.
On the P5 send path, CONFIG.REQUEST cell_id is derived from
msg->phy_id rather than hardcoded to 0.
On the receive side, slot indication tracking (old_sfn/old_slot) is
promoted from static scalars to NFAPI_CC_MAX arrays indexed by
msg->cell_id, renamed to phy_id consistently. cuBB does not populate
ind.header.phy_id reliably in incoming messages; it is set from the
transport-level cell_id instead.
All phy_id and cell_id values are now consistently 0-based across the
aerial boundary, eliminating all ±1 conversions:
- nr_param_resp_cb: req->header.phy_id = p5_idx (was phy->id).
Fake PARAM.RESPONSE injection uses p5_idx=0 for the first cell.
- phy_nr_slot_indication: CC_id = ind->header.phy_id directly,
no guard or subtraction.
- fapi_nvIPC.c: cell_id = msg->phy_id with no subtraction.
- All P7 send functions: header.phy_id = phy_id with no +1.
For multi-cell, injecting p5_idx=0,1,2,... maps directly to
phy_id=0,1,2,... and cell_id=0,1,2,... with no conversion at any
boundary.

Remove unnecessary log
We already check for number of received samples above after receiving.
When aligned to the slot boundary for synchronization, this length of
the samples is no longer samples_per_slot. # Please enter a commit

Validate signed MR commits and update contribution guidelines
This MR adds validation for signed merge request commits and updates the
contributing guidelines including the requirement for signing commits.
- The CI will warn in the Verify Guidelines stage if any commit in the
merge request is unsigned.
- Checks all commits in the MR source branch that are not present in
the target branch
- It then verifies if all these commits are signed
- Update contributing guidelines to include commit rules and signing
commits using git commit -s.
- The CI will also check if there are any merge commits and fail the
pipeline in that case.
fix (F1 Handover): do not trigger when no DRB is configured
Prevent triggering F1 handover for UEs without any DRB, to align with
3GPP TS 38.473 clause 8.3.1.2 and avoid initiating an invalid UE Context
Setup Request in the F1 handover flow.
Changes:
- Add a preliminary check in nr_rrc_trigger_f1_ho() to verify at least
one DRB exists in ue->drbs
- Abort F1 HO trigger early when no DRB is present, with warning

Move the subframe scaling logic outside the PRACH slot loop to prevent the
subframe index from being incorrectly multiplied multiple times when there
are multiple PRACH slots per subframe.
Add AoA selection to vrtsim
Adds AoA as a selection parameter in vrtsim. Different UEs can be
configured at different arrival angles, emulating distinct spatial
locations, which can serve as an enabler for beamforming evaluation.
fix(nrLDPC_coding): Remove ldpc_xdma
Arguments for removing:
- There are no resources to maintain it. Including no machine with the
board.
- There is no clue that someone is actually using it.
- The library is not standard/cannot be generalized. It was designed for
a specific solution and cannot be used for another.
- The standard AAL (BBDev or other) should be privileged for LDPC offload
to a hardware accelerator.

CI: Various CI adjustments
- RAN-SA-FHI72-CN5G: activate/inactive carriers on VVDN RU - to check if
it improves reliability and stability of the pipeline
- RAN-SA-FHI72-CN5G: update CN with new IP range - avoid IP address
overlap with CN used in RAN-SA-AERIAL-XXX pipelines
- RAN-SA-B200-Module-SABOX-Container: test with deltaMCS in SC-FDMA test
case
- RAN-NSA-B200-Module-LTEBOX-Container: adjust PRACH DTX threshold to
reduce number of false RA attempts on eNB
- remove retx check in RAN-SA-Multi-Antenna-CN5G and RAN-SA-AERIAL-CN5G -
to avoid false CI failure caused by unsuccessful retx check of
interfering UE
- adjust RAN-SA-Multi-Antenna-CN5G and RAN-SA-AERIAL-CN5G configs to
improve UL throughput
Manual testing showed that lowering the RX gain reduces UL
retransmissions and improves overall UL throughput in the 100 MHz 2x2
test case of the SA-Multi-Antenna CN5G pipeline.
Add vvdn-activate-carriers.sh to verify RU PTP synchronization and
configuration. Activates carriers on VVDN RU by editing sysrepo running
datastore (INACTIVE->ACTIVE).
Add vvdn-inactive-carriers.sh to reverse the operation, setting all
carriers back to INACTIVE via sysrepocfg.
After the changes introduced in !3991, multiple PRACH PDUs can be
pushed from L2 to L1 before being processed. This leads to the PRACH
queues filling up and triggering "PRACH occ queue is full" issues on
the gNB.
This commit increases the queue size from 8 to 16, providing additional
buffering and preventing queue overflows as reported in #1072.

T-Tracer & Data Recording v1.1: UL PHY trace modularization and recording
enhancements
Based on the plan with @schmidtr and @roux-cedric, we agreed to enhance
the data recording in two phases:
- Phase 1: Update Data Recording framework to get All internal Massive
Updates and enhancements through the whole framework public
- Phase2: Restructure T-Tracer Apps and remove all Mems in gNB and UE
Softmodems to Get data on T-tarcer Apps for all activated Messages
symbol-by-symbol, and related Meta-data, then do the aggregation on
the T-tracer App. So, there is No Memory Creation at all on the 5G NR
Stack.
This Merge Request is for Phase 1. We address the comments given in: !3632
Summary: Refactor T-Tracer instrumentation for UL PHY data capture and
improve the data recording application (v1.0 → v1.1). This MR extracts
inline T() macro calls into modular wrapper functions, adds Unix timestamp
fields to trace messages, implements a 4-state shared memory protocol for
gNB/UE tracers, and delivers an improved synchronized recording architecture
in Python.
Changes:
- T-Tracer: Modular UL PHY trace wrappers
- Add T_messages_creator.c/.h with 7 wrapper functions (log_ul_fd_dmrs,
log_ul_fd_chan_est_dmrs_pos, log_ul_fd_pusch_iq,
log_ul_fd_chan_est_dmrs_interpl, log_ul_payload_rx_bits,
log_ul_payload_tx_bits, log_ul_scrambled_tx_bits) and a static
log_ul_common() helper
- Register T_messages_creator.c in the T library CMake build
- Update T_messages.txt definitions: Remove string timestamps and get
time stamp directly from sending_time of T-macro.
- PHY: Replace inline T() calls with wrappers
- gNB (nr_ulsch_demodulation.c, nr_ul_channel_estimation.c,
phy_procedures_nr_gNB.c): replace inline T() calls with
T_messages_creator wrappers
- UE (nr_ulsch_coding.c, nr_ulsch_ue.c): replace inline T() calls with
log_ul_payload_tx_bits and log_ul_scrambled_tx_bits wrappers
- Remove deprecated log_tools.c/.h and its CMake reference
- T-Tracer gNB & UE apps: Enhancements
- Implement 4-state shared memory protocol (WAIT → CONFIG → RECORD → STOP)
for coordination with the data recording app
- Add event_trace_msg_ul_data struct with 27 UL metadata fields
- Refactor event loop to poll()-based with proper signal handling
- Separate project IDs (gNB=2335, UE=2336) and ftok paths for independent
shared memory segments
- Update shared memory sizing: Limit number of records to
NUM_MESSAGES_PER_SLOT=5, 100 slots
- Data Recording App v1.1
- Improved architecture with thread pool and barrier synchronization
- Frame/slot-based message grouping with per-slot validation
- atexit/signal-based cleanup for graceful shared memory detach
- Delete legacy data_recording_app_v1.0.py
- Library improvements
- config_interface.py: remove legacy YAML config reader, streamline to
JSON-only
- shared_memory_interface.py: new module for shared memory
attach/read/protocol
- wireless_parameters_mapper.py: new module for NR parameter mapping
- data_recording_messages_def.py: updated message definitions for
27-field struct
- sigmf_interface.py, sync_service.py, common_utils.py: remove unused
imports and dead code
- Documentation
- Update data_recording.md for v1.1 architecture and usage
Arguments for removing:
1. There are no resources to maintain it.
Including no machine with the board.
2. There is no clue that someone is actually using it.
3. AAL is privileged for LDPC offload to a hardware accelerator.
7.2 FHI with XRAN K release
Purpose:
Implement the O-RAN 7.2 Fronthaul interface using O-RAN Software Community's
XRAN release K. The new features of the release K can be leveraged and it is
compatible with DPDK version 24.11.4.
For more details please refer to the MR !3444 description.
- refactor timestamp handling
- Replace string-based SENDING_TIME with integer SEC/NSEC fields.
- Designed the shared memory protocol with a 4-state machine (STATE_WAIT=0, STATE_CONFIG=1, STATE_RECORD=2, STATE_STOP=3) for command/control between the recording app and the T-Tracer service
- Implemented two shared memory segments: one for reading commands (addr_rd) and one for writing captured data (addr_wr)
- Created event_trace_msg_ul_data struct mapping all 27 UL metadata fields (frame, slot, datetime, MCS, DMRS parameters, etc.) by name from the T-Tracer database
- Implemented setup_trace_msg_ul_data() using the G() macro to map field names to indices at startup
- Wrote the main event loop using poll() to avoid busy-waiting, with get_event() to receive T-Tracer events from the softmodem socket
Use log_ul_fd_dmrs, log_ul_fd_pusch_iq, log_ul_fd_chan_est_dmrs_pos,
log_ul_fd_chan_est_dmrs_interpl, log_ul_payload_rx_bits.
Remove redundant T_ACTIVE() guards and old timestamp formatting.
