CI: Creation of F1 Handover pipeline
In this MR we are modifying/adding all the required files (.xml, .conf,
.yml) in order to create a pipeline on Jenkins that allows us to test
OTA F1 handover.
Remove the runtime, which is not interesting, and add instead
- test name and if the test failed
- the threshold checks, if any, and
- possible additional information about test failures.
Prior to this change, each test would have, as label, it's description.
This leads to many labels, which are normally reserved for grouping
tests. Move the description into a custom property instead.
Since we rely on the JSON output for the generation of HTML reports, we
need to also extract the description from the generated JSON. However,
custom properties are only logged starting from cmake 3.30. For
back-wards compatibility, write an additional, separate environment
variable TEST_DESCRIPTION from which the description can be read as a
fallback.
For the add_timed_physim_test(), this has been already done in a parent
commit.
Reworking BWP configuration
This MR reworks the configuration via fail of additional BWPs. Moreover, it
allows for a single BWP to be configured for a given UE at a given time (BWP
switch possible only via reconfiguration). It also reworks PTRS configuration
for consistency with the BWP one.
Fixes and updates for UL scheduling, notably DSUUU
Fix a number of problems that stem from !3521, notably regarding Msg3
scheduling, retransmissions in "UL-heavy" TDD scenarios, and BSR
handling. Modify a CI test to run a UL-heavy TDD scenario, and add
documentation for UL-heavy TDD scenarios.
The parameter is either set to 10 (the default, so not necessary), or to
0 forcing the gNB to schedule the UE all the time, which is only
necessary in specific scenario, and here simply wrong.
gNB: adaptive DL/UL MCS based on reported SSB-SINR and measured PUSCH SNR
Currently this is used esp. if the number of rounds is limited to 1
(e.g. disable_harq).
A future commit will enable to deploy physical simulators via docker.
Hence:
- Move the script to run out of deploy_oc_physim(), to make it more
generic (later commits will introduce other scripts)
- pass the working directory (the function will be moved into
cls_oaicitest, as it fits neither cls_containerize nor cls_cluster
when deploying the tests from source)
- not using ci-scripts: don't hardcode a specific path, just use the
working directory
- avoid helm-specific pods summary, and put it into the general "physim
logs"
- remove helm-specific "release", and use a generic name for results
- always log pod logs and status to debug, even if deployment was not
successful or tests did not finish.
Instead of making the function a class member, make it an instance
member because (1) it is more aligned with other functions, notably,
run(), and (2) especially for RemoteCmd() it can be faster, as
successive exec_script() calls do not require a new SSH connection.
RFSim test for 10 UEs/process
This MR adds a testcase and changes required to run 10 UEs in a single
process with RFSim
- Added deregistration for all connected UEs
- Refactored MAC/RRC instance handling
- made map_current_symbol thread safe
- made opeanir0_cfg thread safe and local
- Added 10UE/process testcase
Update RFsim CN
- Update RFsim CNs to latest version
- update the MBIM stop script to remove IP addresses (we don't use this
script directly, so it does not have an impact)
The CI detects whether a UE connected (and has a PDU session) by trying
to read the IP address. It therefore assumes that as long as the UE is
not connected, no IP would be present.
With the existing stop_quectel_mbim.sh script, this was not the case; it
would simply leave the IP address. Modify this script to flush all IP
addresses on disconnect to remedy this.
RF emulator and improvements of the timers
RF emulator:
Add an RF library emulating a real device without the need of a real
device. This is thought to enable using phy-test without requiring a
radio device or channel simulation. The library synchronizes on the
real time clock, drops TX and generate noise on RX. Noise generation
can be disabled and the noise level configured.
Timers improvements:
- Fix standard deviation for merged timers
- Add display of ULSCH decoding timers
- Add decoding timer in AAL
CI: speed up and simplify build, remove unnecessary Python code, remove --eNB* parameter list
This cleans up the CI framework for running end-to-end tests, and
improves the integration with OAI code. Specifically
- cleanup build_oai and helpers to output all text, which is captured
better by the CI
- build some images in the Cluster-Build in parallel to increase speed
- remove all --eNB{,1,2}{IPAddress,UserName,Password} variables. Those
were indexed through "instance" and "server ID" and are replaced with
the actual node name. I consider further cleanup to introduce a
"global" XML file node name so we don't need this in each step and
instead define this once.
- individual cleanup
A previous commit changed to use archiveArtifact() to recover CI logs,
and then attempted to "guess" the L1/MAC stats file name through a
regex. However, the format "enb-[0-9]+" is not correct, as
archiveArtifact() puts the task ID ("[0-9]+") BEFORE the file name
(here, "enb"). So, make it more generic and match the final "-enb.log"
("$" means "end of string").
Fixes: 244ea8fc22 ("Use archiveArtifact() for TerminateeNB()")
