It is not necessary (the final undeploys at the end are "always_exec"),
and makes the CI potentially fail since there is nothing to copy at this
point.
check for IP once before sleeping in case UE IP address exists, which
should speed up the CI. With this, Only print the actual attach command
once. Print errors only at the beginning. This should simplify attach
command output logs.
CI: refactor iperf3 UDP analysis function
- add helper function to covert reported bitrate values to Mbps for calculations
- clean up the UDP analysis function, improve test report formatting
- fix an issue where Gbps values were incorrectly reported
(example: https://jenkins-oai.eurecom.fr/job/RAN-SA-AERIAL-CN5G/4802/)
- update CI unit test report checks to match the new formatting
Rename the library to reflect that it's more a generic AAL driver than
specifically for AAL. To this end, rename some documentation.
As of this commit, the options are still called nrLDPC_coding_t2. The
next commit will correct this.

Add a CU-UP load tester and improve GTP performance
This adds a simple tester program for the CU-UP. It sets up a number of
UEs/bearers in the CU-UP via the E1 interface, then streams data in
downlink/uplink (as seen by the CU-UP). More information is available in
tests/nr-cuup/README.md.
Includes some fixes to properly verify that SCTP is installed, and use
"the right cmake way" to use it in cmake code (see commit for details).
Remove these F1-C port numbers. The configuration is not actually
applied, and the default F1-C port number 38472 (see F1AP_PORT_NUMBER)
is hardcoded in the F1 module.
For the moment, I leave the configuration option, in case we want to
allow to configure the port numbers later).
Now that we reliably receive SIB19, we can set the ntn-UlSyncValidityDuration-r17 to a sane value
and thus make sure that the UE always has up-to-date SIB19 information.
Since the parent commit, the ra_ResponseWindow will be chosen
automatically. Correspondingly, remove most ra_ResponseWindow options
from configuration files in the repository.
One problem in some mu=1 configs is that the ra_ResponseWindow=4 (10
slots), which might be overly restrictive if the L1 slot ahead is
somewhat close to 10 (e.g., 6), in which case we might not be always
able to allocate Msg2 in time.
A notable exception here is gnb-vnf.sa.band66.u0.25prb.nfapi.conf, in
which we still provide it (1) since it uses a non-standard configuration
of a ra_ResponseWindow longer than 10ms (see also issue #916 for more
information) and (2) as an example.
- Add helper function to normalize bitrate values to Mbps for calculations.
- Add helper function to extract data from iperf test report.
- Clean up the UDP analysis function, improve test report formatting.
- Fix an issue where Gbps values were incorrectly reported due to inconsistent
unit parsing.
- Update CI unit test report checks to match the new formatting.
Fix Dedicated BWPs
- Improve SearchSpace selection
- Improve CORESET selection
- Fix fill 'initialDownlinkBWP->pdsch_Config' when there are
DedicatedBWPs
* This fixes the reported 'RSRP = 0' issue when the UE is in the
InitialBWP and we have DedicatedBWPs configured
- Add a 'common' type SearchSpace in the NR_BWP_DownlinkDedicated IE for
DedicatedBWPs
- Fix hardcoded 'controlResourceSetId' by making it dynamic
- Remove 'searchspaceid' from 'verify_agg_levels' function because it
was used only for LOG
- CI: Add DedicatedBWP to '40 MHz TDD F1+E1 SA' in
'RAN-SA-B200-Module-SABOX-Container'
Following frequency change in the pipeline, we observed degraded UL channel
conditions resulting in low UL throughput. Increasing attenuation on the gNB
side was found to mitigate this issue by improving UL channel quality
and reducing UL noise power.
Increase tested UL and DL bitrates in OAIUE pipeline.
RAN-Container-Parent: Auto-generate artifact in failure case
RAN-Container-Parent uses Jenkinsfile-GitLab-Container, which only
triggers sub pipelines, then collects their results. However, if a sub
pipeline did not generate an artifact, the result was skipped. It would
also not show it in the automatically generated result page, when it
should.
Remedy this by automatically generating a file with a link to the
pipeline if the artifact could not be retrieved, which
1. Will give a link, which is easier for developers to follow to the
pipeline than manually clicking through Jenkins,
2. Makes the failed pipeline appear in the list of failed pipelines.
CI: test T2 with DPDK 22.11
Following the upgrade of T2 to the latest firmware, DPDK 22.11 is now required.
This MR updates the testing pipeline to ensure compatibility and deployment of
T2 physims with DPDK 22.11.

Build and run OAI physims with DPDK version 22.11 for testing with the latest
T2 firmware release. Environment variables PKG_CONFIG_PATH and LD_LIBRARY_PATH
are set to point to the custom installation path of DPDK v22.11.
CI: Change RU in Aerial setup from Foxconn to WNC
- Change frequency in the gNB config file, from 3.75GHz to 3.5GHz
- Add high throughput tests with may_fail tag (1Gbps in DL and 90Mbps in UL)
- Update Aerial tutorial to match the changes
This commit reduces the UL throughput target in the 2x2 test to align
with the host’s performance capabilities. The adjustment ensures more
reliable and consistent CI results.
Based on observations from testing on acamas, the interval between DL
disruption and the UE synch check needs to be increased - the UE takes
longer to go out of sync . A sleep of 15 seconds has proven to be a
reliable value to ensure constant results.
Add SYS_NICE capability to enable setting thread priority and affinity
in rfsim5g tests. This improves execution speed in test cases with
heavier processing workloads.
When migrating from RHEL (on cacofonix) to Ubuntu 22.04 (on acamas), the `nc`
command needs to be replaced by `ncat`. The version of `nc` available on Ubuntu
is the OpenBSD variant, which lacks support for some options used in our scripts.
`ncat` from the Nmap is used instead.
RF simulator: Fix concurrency issues during new client connections
- Fix concurrency issues happening when a new client connects, sometimes
leading to a total softmodem deadlock.
- trace in 4G RAR processing to debug ci result
