CI: Add unified Jenkinsfile for all test pipelines
This MR introduces a single Jenkinsfile to cover all current CI test pipelines
Improvements:
- correct reporting of the start timestamp in the HTML report
- harmonize log collection - always collect as test_logs_${env.BUILD_ID}.zip
Fix unsigned to signed decoding parameters to allow for 'no affinity'/'no pin'
threads to CPUs
By default, 'L1_rx_thread_core', 'L1_tx_thread_core', 'ru_thread_core' are set
to '-1' but the values were decoded from config file as unsigned instead of
signed types, thus, it was not allowing to set them with '-1' from config file.
PRS bug fix and CI Integration
- Fix the bug in PRS channel estimation while copying memory to compute the
impulse response
- Integrate PRS testing to CI
Simplify node management in CI, handle SIGINT
- Make a single <node> XML step entry common to all XML steps to harmonize code
- Handle SIGINT to make it possible to more easily stop the CI script.
Bugfix: save old tunnel info to remain the user plane connection while rolling
back to source DU due to handover failure
This MR closes issue #984 that UE lost the data plane connection while rolling
back to the source DU due to handover failure.
NR UE: fix PDCCH LLR indexing for different search space RB sizes
After !3603 (merged), when multiple search spaces have different CORESET
configurations (different number of RBs), the LLR buffer stride must be
calculated based on the maximum RB size across all search spaces, not the
current search space's RB size.
The LLR buffer is allocated with size based on get_pdcch_max_rbs(), but the
demapping function was using coreset_nbr_rb (current search space) for symbol
stride calculation, causing incorrect LLR extraction when search spaces have
different RB configurations.
This MR tries to fix it.
Closes#1021

Change registry name env var content
Currently setting REGISTRY="" in a .env file results in docker failing to find
/image-name:tag. This corrects that, so it looks for local images named
image-name:tag.
Following the change to use:
image: ${REGISTRY-oaisoftwarealliance/}${GNB_IMG:-oai-gnb}:${TAG:-develop}
the REGISTRY variable must now include the trailing slash.
CI: ensure clean iperf3 server startup
- Resolves issue with iperf3 test failure in RFSim5G multiue test
- Minor fix of iperf3 test descriptions in RFSim5G pipeline
Fix for scenario with no CSI report configured for CSI-RS
After changes in !3714 (merged), if we select to measure RSRP on SSB and not
CSI-RS (default option) and there is a single antenna port (so no MIMO report
either) we won't schedule any CSI-RS measurements for the UE. In that case
ideally we shouldn't set do_CSIRS = 1 in configuration file but still the
option is possible. So the fix is to not perform any measurements at UE on
that CSI-RS but not asserting.
Closes#1015
Before starting a new iperf3 server instance in CI tests, explicitly kill any existing
iperf3 processes bound to the same port. This prevents conflicts or failures caused by
leftover iperf3 servers from previous runs that did not terminate properly or on time.
The cleanup is performed using `pkill` before launching the new server.
Handle GTP receiver errors, fix memory leaks, add CU-UP test
- Fix use-after-free bugs in GTP by properly stopping the receive thread(s)
- Fix a bug from !3519 (merged): QFI 0 is a valid QFI
- Fix multiple memory leaks in CU-UP, E1, CU-UP load tester, SCTP
- Add a (conservative) functional CU-UP test that verifies that the load tester
and CU-UP work. Test only a low throughput, as it will run in parallel with
other tests.
improvements in formatting and LOGs in DMRS common functions at MAC
DMRS LOGs at MAC were misleading. This MR tried to improve them (and also
adds some formatting fix).
Update based on !3645
Note: For some test configurations we still need to provide
ra_ResponseWindow, for more details, check commit message of

By configuring the Jenkins pythonExecutor to match the test machine, we can use
localhost as the node for running individual test cases. This change makes it
easy to move tests across machines, as the only adjustment needed is updating
the pythonExecutor in Jenkins.

CI: Upgrade Aerial setup to 25-2.1
The purpose of this MR is to upgrade the cuBB image in the Aerial setup to
release 25-2.1 and update the doc/Aerial_FAPI_Split_Tutorial.md accordingly.
CI: Upgrade HO setup to use an attenuator
The goal of this MR is to upgrade HO CI setup to include a digital attenuator
that will allow us to trigger handover by attenuating the signals on the DUs.
OAI UE: add shared RSRP Table 10.1.6.1-1 mapping function to helpers and adopt
it RRC UE
- Add to common/utils/nr/nr_common remove from NR_MAC_UE/nr_ue_procedures.c
- Adopt in asn1_msg.c for MeasurementReport: this solves the following possible
assert:
Assertion (enc_rval.encoded > 0) failed!
In do_nrMeasurementReport_SA() /oai-ran/openair2/RRC/NR/MESSAGES/asn1_msg.c:898
ASN1 message encoding failed (MeasResultServMOList, 18446744073709551615)!
Motivation: unify RSRP-to-index mapping across layers and fix NR RRC
MeasurementReport encoding failures due to out-of-range values by reusing the
validated mapping.
Note: NR_RSRP-Range.c constraint: /* (0..127) */
Also refactored MeasurementReport to improve the code.
Remove B200-specific clock-rate setting
Avoid this clock-rate setting, as we already do it around usrp_lib.cpp:1121, so
it is superfluous. For instance, we also do not set a master clock rate for N3xx
either. This also enables us to synchronize B200 for handover settings,
e.g., for !3651.
See the commit message for more information about synchronization.
Remove NR L2 simulator code from UE
This MR removes NR (SA and NSA) L2 simulator from the codebase. The code, at
least at the UE side, was done at a time where there was no clear L2/L1 split
leading to a complex implementation that never worked as expected. The L2
simulator has been broken and removed from testing for long time and, once it
needs to be revived, it would require a complete new implementation.
Assign antenna ports correctly for 1 and 2 layers for aerial.
With this change aerial successfully decodes PUSCH with 2 UL layers.
The code should use sched_pusch->dmrs.num_dmrs_cdm_grps_no_data == 1 rather
than NFAPI_MODE != NFAPI_MODE_AERIAL, but that will make the changes a bit
more extensive.
Prior to this change, sending antenna_ports.val = 2 with rank 2 would tell
the UE to transmit on DMRS ports 2,3 rather than 0,1 causing it to not decode.
[CI] Ensure multi-arch DockerHub Push after successful image build
This merge request improves the CI script to ensure that the DockerHub-Push
stage executes whenever:
- All Image Build stages succeed &
- doBuild is true &
- The event is a PUSH
This behavior ensures that Docker images are published whenever the image build
stages succeed, regardless of any failures in the Image Test stages.
Jetson ARM64/V8 and AMD64 images will now be published on DockerHub under the
same tag (develop or WEEK_TAG) to provide multi-architecture images.
Optimization of PDSCH precoding operation
x86/aarch64 optimizations for precoding, more complete timing reporting in
nr_dlsim. Timing report in nr_dlsim now shows the total PDSCH generation time
and is broken down into Layer mapping, resource mapping and precoding.
The optimizations for x86 are basically reorganizing loops (for AVX512,AVX2,
NEON but not SSE2) to minimize repetitive instructions when formatting of the
precoder weights, and creation of inline functions for complex multiply-add.
AVX512 optimization was added. requiring AVX512BW. Detection of up to 4 PRBs
with common PMI for efficiency with AVX512 (was 2 in develop for AVX2).
For aarch64, native coding of the precoder to avoid inefficient SIMDe
translations for this operation.
nr_dlsim now uses default precoding indices depending on the scenario instead
of 0 which doesn't do precoding at all.
See merge request description for nr_dlsim test results.
Replace the previous add_timed_physim_test() macro with add_physim_test()
to use a single, unified function for defining physim tests. This simplifies
the test configuration and removes redundant macro definitions while keeping
all existing functionality.
This change follows up on the earlier addition of support for including
custom timing threshold files (PHYSIM_CHECK_FILES).
Update existing tests accordingly.
Add missing timinig analysis scripts to RHEL9 physim docker image. These files
are now copied from the build stage to /oai-ran/openair1/SIMULATION/tests/,
where they are expected by ctest.
Resolves following issue when running ctest in docker container:
CMake Error: Error processing file: /oai-ran/openair1/SIMULATION/tests/RunTimedTest.cmake
Fixes to prevent assertion due to 0 PRB allocation

free nested ASN.1 structures in cell group configuration.
Fix 2: Removed premature nullification of dedicatedNAS_Message->buf in
dlInformationTransfer processing to allow proper ASN.1 cleanup.
Fix 3: Fixed memory ownership in nr_rrc_process_dedicatedNAS_MessageList by
copying OCTET_STRING data instead of transferring ownership, preventing
ASN.1 cleanup from losing track of allocated memory
Closes#828
fix RSRP computation at UE
Conflicts between !3595 (merged) and !3596 (merged) leading to double conversion
of RSRP into index in L1 and L2. With this fix it is only converted in L2.
Replace int16 min when obvious
INT16_MIN doesn't have a opposite value on 16 bits, so SIMD abs (absolute()), or
simple C operations doesn't make the expected result.
example:
(gdb) p (short)-(short)-32768
$4 = -32768
(gdb)
This MR replaces constants INT16_MIN by -INT16_MAX (so -32767) in places where
it used for mathematical operations. This is not perfect, nevertheless reduces
overflow probability.
We saw in some places a dirty case: code do first calls to _mm_adds_epi16
(or subs), so because of the saturated operations, the probability to reach
32767 and -32768 is higher than the other numbers but, _mm_abs_epi16(), or
negate operations (conjugate) can follow, that is making strong error as
abs(-32768)=-32768
Also, don't use "set -x" debugging for oc login command:
ci-scripts/cls_cmd.py:242 sets BASH_XTRACEFD=1, which makes that all
"set -x" output is in stdout, leading to a redirect to the file into
which we redirect. This would lead to the following error with
unsuccessfull oc login:

Make all targets compile
This MR enables us to compile all targets, and does that in one CI test. This
closes#726. Now, this should work:
cd ~/openairinterface5g
mkdir build && cd build
cmake .. -GNinja && ninja
To achieve this, I did the following:
- some targets have been fixed (warnings, errors)
- some targets have been removed when they did not seem to serve a good purpose
(e.g., an almost empty test)
- some targets have been commented (e.g., LTE simulators, some unitary tests)
which we maybe want to revive in the future
- some targets built when just building with ninja, but not all. For instance,
telnetsrv_enb would typically build, but it was missing a dependency. Doing
cmake .. -GNinja && ninja telnetsrv_enb would show this (in develop)
To help with the last bullet point, there is a script compile_targets.sh that
can compile targets independently (and in parallel, to not wait for ages) to
show that targets compile properly compile-targets.patch.
In almost all cases, the problem is that a specific module uses the logging
module, which depends on T, which needs to dynamically create headers. The way
to do this is to have a dependency, and many targets use generate_T or {T_LIB}
({} intentional: T might be absent, so then it evaluates to nothing). However,
not all do this, and those that depend on T actually don't depend on T, but on
the logging module, which in turn depends on T. So in many places, a simple
dependency onto log_headers fixes this problem, and generate_T or {T_LIB}
simplifies the dependency (but not always). The commits should have more info.
Note that at least the targets in FlexRIC do not all compile, at least in the
configuration that we use in docker/Dockerfile.build.ubuntu. So for the latter,
we cannot build with a simple ninja, but FlexRIC seems to be the only one that
does not compile. Since FlexRIC is a separate repository, that needs to be
addressed in the corresponding repository.
Previously, the script attempted to directly merge ${merge}, which could f
ail if the branch was not already available locally. This update explicitly
fetches the branch from origin and then merges FETCH_HEAD with --ff, ensuring
the merge works even when the branch is missing locally.

The function get_nr_RSRP() and get_nr_rx_total_gain_dB() are not used anywhere

CI: Updates for HO and AW2S pipeline
This MR introduces several CI updates:
- Change center frequency from 3439 MHz (n78) to 4185 MHz (n77) in HO setup to
prevent interference with other lab setups.
- Enable attaching multiple AmariUEs simultaneously in the AW2S pipeline - save
~25s.
- Update RX gain configuration on AmariUE - improve DL throughput.
BWP with no PRACH occasions
This MR includes fixes at gNB and UE in case the current BWP has no PRACH
occasions, i.e. we need to switch to initial BWP.
Lower the RX gain used by the Amarisoft UE in CI tests to prevent DL signal
saturation. This resolves an issue with low DL throughput observed in CI.
RX/TX signal levels on the Amarisoft UE can be checked with "t spl" command
in lteue; MAX values should not approach 0.

Improvements to RRC PDU session and DRB handling logic
This merge request introduces a major simplification and cleanup of the gNB RRC
PDU Sessions and DRBs handling logic. The core goals of this work are to:
- Replace fixed-size PDU Session, DRBs and QoS arrays with dynamic containers
- Simplify and modularize helper functions for session/DRB management
- Prepare for further refactoring of the PDU Session state machine
- Improve code safety and maintainability through better bounds checking
NR UE: in nr_ue_scheduler.c set LCID_buffer_remain to 0 if RLC indicates not
more bytes in buffer
If the RLC indicates that there is no more data in the buffer, also the
scheduler's LCID_buffer_remain should be set to 0. Else the UE sends BSR
indicating it has data to be transmitted. The gNB would then unnecessarily
schedule UL for this UE, which would not be used, as there is no actual data
to be transmitted.
Extend t300 in multi_ue rfsim testcase
Extend t300 to 1000 to increase the time the gNB has to handle MSG3. Hopefully
this prevents the UEs from timing out after MSG3. Add UE id to timer timeout
LOGs so the UE behavior can be traced through the stack.
Code cleanup (SRS, config files and more)
- Remove deprecated elements from some configuration files (also closes#997)
- Improve SRS code with a better separation between common code and gNB/UE code
- Other minor compilation improvements
Implementing the option to have more than 1 RSRP in CSI report
In collaboration with NI/Emerson.
The standard allows up to 4 RSRP measurements in CSI report (1 full and the other
differential). In current OAI, we just configure 1 RSRP report for the strongest
SSB. This MR allows to configure at gNB more than 1 RSRP report (depending on
config file, number of SSBs and UE capabilities) and makes changes at the UE to
send this report.
replace bad DCI by specific message for each case and add checks for bad...
Replace bad DCI by specific message for each case and add checks for bad
pointers, or sanitize detected warnings. Then fix several issues in DCI
decoding. With this MR, LTE UE has less bad DCI, and each bad DCI has a
reason better diagnosis.
Add nr-cuup to run_locally.sh
E1 deploy wasn't enable in the run_locally.sh script to run the CI on a local
machine. This MR is adding it. It was validated locally.
Fix UE DCI monitoring after RRC setup
After the UE is configured with pdcch-Config, it continues to monitor
fallback search spaces in pdcch-ConfigCommon for DCI with C-RNTI.
The rational is that after sending RRC Setup the network won't know if
the UE has received and successfully applied it. Hence the network would
still continue to use the fallback DCI till it receives RRC setup
complete.
Closes#954
Fix memory allocation issue in KPM RAN function sd parameter handling
This fixes a segmentation fault in the gNB when a KPM xApp sends the sd
parameter in the subscription message.
The segmentation fault seems to occur because *sd is uninitialized when
malloc(**sd) is called. This causes a double dereference of an uninitialized
pointer - **sd reads a random memory value which becomes the size parameter
for malloc(), leading to unpredictable memory allocation and segfaults.
This fix allocates the size using malloc(sizeof(uint32_t)) instead of
dereferencing the uninitialized pointer.

Fix for gNB max feedback time parameter
This bug is causing assertions like the following

In nr_csi_meas_reporting() /oai-ran/openair2/LAYER2/NR_MAC_gNB/gNB_scheduler_uci.c:282
CSI structure is scheduled in advance. It should be free!
because the PUCCH structure would be smaller than it should be causing
overlapping.
gNB scheduler small fixes
A couple of fixes in gNB scheduling function. Removing a superfluous input from
CCE function and adding a missing call to reset beam allocation.
Ldpc encoder zc384 optimization
This is a modification for the ldpc encoder which improves performance for
high-throughput cases. It contains a newly-generated file for innermost part of
the parity bit generation which, for AVX512, uses the mm512_permutex2var_epi8
instruction and for 128-bit (aarch64) the mm_alignr_epi8 (vextq_s8) in the
computation corresponding to each non-zero bit of the H matrix. This allows for
removing a very large memcpy and reduces the memory demand for the parity matrix
computation. For the moment this is limited to largest case in BG1, namely
Zc=384. This is the only format used when the number of segments after codeblock
segmentation is large (>8). This improves the timing required for ldpc parity
bits generation by more than a factor 2 with AVX512. This significantly reduces
the total time to generate the DLSCH/PDSCH.
See the merge request description for numbers.
Speedup complex rotate for aarch64
This is a simple optimization for aarch64 for the "rotate_cpx_vector" used for
the phase_rotation in 5G NR. It provides a speedup of around 1.5 on high-end
aarch64 targets compared to the SIMDe translated version. It is implemented with
native NEON intrinsics and was largely inspired by suggestions from ChatGPT 5 :-)
