Extend F1 Handover test
do 1 more handover in the same test to verify robustness
- This MR keeps a simple ping after the second handover since there are
still issues due to scheduling starting too early, that is as soon as
the UE context is added. This leads to retransmissions that could
eventually lead to a test failure. The issue will be fixed in a future
MR.
add check on connected DU to verify successful handover
- a new telnet function gets in input the UE ID and returns the ID of
the connected DU
wait some time after deploying DU to mimic time for measurements
Optimization for unused symbols in NR UE
After processing TX frequency domain data skip IFFT call for symbols
that aren't used, the time domain buffer is memset instead.
Biggest benefit is when UE does not transmit PUSCH, or PUSCH is using <
14 symbols
[E2 agent] RAN Control SM - support for REPORT Style 1 ("RRC Message" and "UE ID" RAN Parameter IDs)
[Spring of Code 2024] contributions
Extended the RAN Control Service Model at E2 Agent to support all RC
REPORT Styles (1 - 5)
Implemented the following RAN Parameter IDs for REPORT Style 1:
1. "RRC Message": any DL-DCCH, and any UL-DCCH
2. "UE ID": as per spec, when the RRC Setup Complete or F1 UE Context
Setup Request detected
feat(oran_fhlib_5g): O-RAN 7.2 FrontHaul Interface on Arm
This MR is enabling the 7.2 FHI on Arm systems.
Even though the performance are yet very bad (UE connection is very
difficult, 100Mbps DL, almost no UL), still I would like to merge this
now since the matter of making the FHI work is rather orthogonal to the
performance issues.
So merging this feature would provide a reliable settlement on top of
which we could then progressively enhance the porting of OAI to Arm.
Especially that would make our work easier by having less features to
rebase regularly on develop.
The main features this MR is made of are:
1. Make the xran patches dual
We provide patches for both E and F releases of xran that handles x86
targets as well as Arm targets. Both patches have been tested on both
types of machines (armix, broadbill). Thanks to @brobert and @changy
for their work on xran.
2. Perform 9-bits BFP compression with ArmRAL
Since the BFP compression implementation provided with xran does rely
heavily on AVX512, we provide an alternative implementation that is
relying on Arm's RAN Acceleration Library (ArmRAL).
As of writing this commit description, only 9-bits compression is
supported. Other IQ width will be added.
This upcoming change does not prevent review to be performed since the
BFP compression functions of ArmRAL are identical except for the IQ
width. Adding further IQ width is therefore very straightforward.
3. Fixes in oran_fhlib_5g to support Arm
The library oran_fhlib_5g needed few changes to successfully compile and
run on Arm systems. Thanks to @brobert for his work on oran_fhlib_5g.
Fix inconsistent maxnoofPDUSessions definitions between NGAP and platform constants
There are 2 different definition of maxnoofPDUSessions (as per 3GPP TS
38.413), one in NGAP lib (set to 16) and one in platform_constants.h
(256 as per specs). The NGAP lib definition is removed in this commit
and replaced by the one compliant with the specs.
This is fixing the warning:

Avoid accessing current_DL_BWP structure when scheduling DCI for other SIBs
Avoid access to mac->current_DL_BWP structure when scheduling DCI for
SIBs other than 1. This is not needed and can cause NULL pointer access
which can happen if the UE has released MAC configuration or has not
started RA yet.
sched_ctrlCommon earlier
This MR configures sched_ctrlCommon earlier, in RCconfig_nr_macrlc().
The objective of this MR is to solve the following Assert in the F1 test:
19897952.126019 [NR_MAC] I Adding new UE context with RNTI 0x3269
/oai-ran/openair2/LAYER2/NR_MAC_gNB/gNB_scheduler_primitives.c:366:15: runtime error: member access within null pointer of type 'struct NR_UE_sched_ctrl_t'
[INFO tini (1)] Spawned child process '/opt/oai-gnb/bin/entrypoint.sh' with pid '7'
[INFO tini (1)] Main child exited normally (with status '1')
Wait before triggering a handover. First, we send it very quickly after
deployment, which can make the DU crash (should be fixed in !3332). Second, a
UE would typically first measure neighbors. While we don't do this with OAI UE,
mimic this somewhat by giving more time.
See also !3332.
* the handover is followed by a sleep and an ping test
This MR keeps a simple ping after the second handover since there are still issues due to scheduling starting too early,
that is as soon as the UE context is added. This leads to retransmissions that could eventually lead to a test failure.
The issue will be fixed in a future MR.
As per spec, UE ID shall be reported when the message event configured by
the Event Trigger Style 1 is set to “RRC Setup Complete" message (UE attach), or
“Xn/NG Handover Request” or “F1 UE Context Setup Request” (Intra gNB Handover).
In OAI RAN, Xn/NG Handover is not yet supported, and therefore not added as the trigger event
in this commit.
Additionally, as the Event Trigger Definition Format 1 is common for both "RRC Message" and "UE ID",
E2 node will report the “RRC Setup Complete" message which the xApp will decode and print.

The fronthaul library ships with BFP compression for AVX512 enabled targets.
This commit adds BFP compression for Arm targets by using the ArmRAL library.
Temporarily deactivate DRB integrity protection in SABOX-B200 E1 testcase
to avoid CI failure due to low measured throughput. Our investigation
suggests that the low throughput is likely due to limitation of the UE
(Quectel RM500Q), which appears to restrict the maximum data rate when
integrity protection is enabled. This limitation is not observed with
Quectel RM520N.
- Cleanup and update of "Machines" table:
- remove asterix - not used in CI
- remove nokiabox - not used in CI
- remove orion - not used in CI
- update of "Lockable Resource" for individual machines - synch with
https://jenkins-oai.eurecom.fr/lockable-resources/
- remove column of "IP Address"
- Update information about build pipelines
The healthcheck interval sets when the first health check occurs after the
container starts. Increasing the healthcheck interval helps avoid marking
the container as "healthy" during the initialization phase of PNF. In
particular, USRP initialization of PNF service may take longer, and deployment
failures can occur even after the 10 seconds interval. Extending the healtcheck
interval provides more time for the service before assessing container health.
Remove memset of the UE TX time domain samples array after trx_write in
RU_write()
This memset is unnecessary and can break openair0 libraries. Some
functionalities, e.g. usrp_lib write_thread expect the samples to be
present in the array after trx_write returns.
The array is always set before being sent either in idft or using memset
so there is no risk of sending the same data twice.

Fixes for E1 and PDU session usage
Fix a number of problems in E1 and PDU session handling:
- For multiple PDU session setup reqs, we send a bearer context setup
each time; fix an assert that was triggered on the second bearer
context setup message
- Add a log for E1 bearer context setup, as already done for
modification and release
- If we get a PDU session setup for an existing PDU session, reject it
as required by the spec [actually, it says to reject individual PDU
sessions; keep it simple for now and reject the entire message, which
might not be correct if there is one new PDU session that does not
exist]
- Add a workaround to handle multiple PDU session setup requests that
come in quick succession for different PDU sessions
