I have to make both together, since they both depend on
AnalyzeBuildLogs().
- remove mkdir for legacy sub-logfiles in build_oai, that does not exist
anymore; also, remove corresponding log analysis, I think we don't use
it and it is overkill (either build works or not)
- manually try to copy "all.txt"
- explicitly list log files to copy, then analyze
- AnalyzeBuildLogs(): pass log files to inspect explicitly
Set the context for each task step. Set the artifact result path based
on the XML, so it is harmonized; currently, most pipelines use the "YAML
path" of docker-compose, but that does not always make sense. For
instance, Ping/Iperf() needs to look up this path, but does not
inherently belong to one specific YAML path (there might even be more).
This class provides a generic "context" for individual tasks about the
current task step, and where to log results. It's used by
archiveArtifact() that would automatically log files in the right
directory, based on a directory in the context, and in a way that order
of files is preserved for long-running pipelines.
Note: this does not actually work. In the pipelines, we see that for
some reason, quectel-CM cannot establish a connection. Manually, it
works though(?)
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.
feat(LDPCImplementation.md): Fix documentation
Few ambiguities and outdated names were found in the LDPC documentation
by Vlademir Brusse (see in the devel mailing list).
- Outdated names of the functions of the segment coding interface.
- Ambiguity about loading of the segment coding libraries.

- 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

Fix overflow when negating minimum int16_t value in precoding
This closes#955
It prevents undefined behavior caused by the minimum int16_t value
(-32768) in two's complement representation. Because possible negation
by multiplying with -1 during precoding cause an overflows since +32768
cannot be represented in 16-bit signed integers and end up again in
-32768 because of overflow, here reveald by using the SIMD functions.
Workaround we use a slightly smaller number than 1 in Q15 Format to
prevent this error. Q15 representation of (integer value -32767) -1 +
2^-15 = -0.999969482421875
remove specific directory for LTE SIM management tools
This is very old code has never been integrated with the "main" OAI

This MR integrates the three binaries for LTE virtual sim management in

Remove --usim-test command line option
Remove the --usim-test option: to my knowledge, it's not used by users,
and is misleadingly placed in various places where there should not be a
difference w.r.t. USIM configuration.
When making the changes, I assumed that --usim-test would be 0 (the
default), which is the case in all executables when not specified in
options except for the nr_dlsim, nr_pbchsmi, nr_ulsim simulators.
The only exception is the initialization of PDCP from the MAC, which
does not seem to be correct (the PDCP is in the CU, so it does not make
sense to call it from the MAC which is in the DU).
Synchronized Real-Time Data Recording Application Addition
The main Features of Synchronized Real-Time Data Recording Application:
- The Data Recording Application runs in parallel to the gNB or UE
server or in another server as Data Recording or Data Lake Server
- It makes use of (an extended version) of OAI’s T-tracer framework
- It communicates with base station, and user terminal
- It synchronizes and combines data traces and control information
(meta-data) from Base station and User terminal into consistent SigMF
data sets
Details on implementation addition:
- T_tracer Extension to Support up to 35 Parameters in the T() macro
- Add traces on gNB PHY UL and related requirement: FD PUSH IQ, FD DMRS, and UL Channel estimates wi/wo interpolation, and Rx Payload bits:
1. The required memories have been created and initialized in:
openair1/PHY/NR_TRANSPORT/nr_ulsch_demodulation.c
2. Those memories: memory for DMRS signals, memory for channel
estimates based on DMRS positions, memory to store slot grid with
channel coefficients based on DMRS positions after interpolation,
and memory to store extracted data including PUSCH + DMRS.
3. The input parameters to nr_pusch_channel_estimation() has been
updated to get the pointer to the added memories of
pusch_dmrs_slot_mem and pusch_ch_est_dmrs_pos_slot_mem
(openair1/PHY/NR_ESTIMATION/nr_ul_estimation.h)
4. The DMRS grid of NR slot and the estimated channel coefficients at
DMRS locations are logged to created memories in:
openair1/PHY/NR_ESTIMATION/nr_ul_channel_estimation.c
5. The function inner_rx in
openair1/PHY/NR_TRANSPORT/nr_ulsch_demodulation.c is updated to log
the extracted ULSCH PRBs and the interpolated channel coefficients.
6. The T-macro() has been called in
(openair1/PHY/NR_TRANSPORT/nr_ulsch_demodulation.c) to trace added
traces: T_GNB_PHY_UL_FD_DMRS, T_GNB_PHY_UL_FD_CHAN_EST_DMRS_POS,
T_GNB_PHY_UL_FD_PUSCH_IQ, T_GNB_PHY_UL_FD_CHAN_EST_DMRS_INTERPL
- Add traces on UE PHY UL and related requirement: Tx Scrambled bits and Tx payload bits
1. Update input parameters to nr_ulsch_encoding () in
nr_transport_proto_ue.h to get number_dmrs_symbols to be added to
meta-data.
2. In nr_ulsch_coding.c: Trace UE PHY UL Payload TX bits (T_message:
T_UE_PHY_UL_PAYLOAD_TX_BITS) including related meta-data and UTC
time.
3. In nr_ulsch_ue.c: Trace UE PHY UL Scrambled TX bits (T_message:
T_UE_PHY_UL_SCRAMBLED_TX_BITS) including related meta-data and UTC
time.
4. Fix the input prameters in nr_ulsch_encoding () called in
(openair1/SIMULATION/NR_PHY/ulschsim.c) since a new input parameter
has been added.
- Add Data Collection Services (T-Tracers for gNB and UE)
1. Add _tracer_app_gnb and t_tracer_app_ue apps to common/utils/T/tracer/Makefile
2. Add Data collection Service for gNB: common/utils/T/tracer/t_tracer_app_gnb.c
3. Add Data Collection Service for UE: common/utils/T/tracer/t_tracer_app_ue.c
- Add Shared memory configuration
(common/utils/T/tracer/shared_memory_config.h), since we will have too
much memory consumption on the stack if the T-tracer is not fast
enough to process the traces or if we have too much traces. As a
result, tracers start to capture data, write data in shared memory,
then close the T-Tracer after getting the recording of N slots. The
Data recording App will read data from the shared memory.
- Add Main app of Data Recording Application v1.0 including: Config
files, SigMF Interface, Config Interface, Sync Service, and def
messages: The data recording App includes mainly the following files:
1. The main app: data_recording_app_v1.0.py that has the data control
service, interact with tracers, data sync and conversion service.
2. The configuration file:
common/utils/data_recording/config/config_data_recording.json
3. The wireless dictionary file:
common/utils/data_recording/config/wireless_link_parameter_map.yaml
4. Config Interface
(common/utils/data_recording/lib/config_interface.py) that reads
the configuration for both gNB and UE.
5. Sync interface (common/utils/data_recording/lib/sync_service.py)
that sync captured data for gNB and UE before saving them in SigMF
format
6. The SigMF Interface
(common/utils/data_recording/lib/sigmf_interface.py) to store
recorded data and meta-data in SigMF format
7. A simple script
(common/utils/data_recording/sync_validation_demo.py) to validate
that the recorded bits from gNB and UE are in Sync
- For more info look to doc/data_recording.md
Pre-initialize this variable. It should be set in pucch2x_scrambling(),

Remove the --usim-test option: to my knowledge, it's not used by users,
and is misleadingly placed in various places where there should not be a
difference w.r.t. USIM configuration.
When making the changes, I assumed that --usim-test would be 0 (the
default), which is the case in all executables when not specified in
options except for the nr_dlsim, nr_pbchsmi, nr_ulsim simulators.
The only exception is the initialization of PDCP from the MAC, which is
not correct (the PDCP is in the CU, so it does not make sense to call it
from the MAC which is in the DU). Instead, always initialize from main,
even in the NSA case (NSA was covered by the incorrect initialization
from MAC).
This in turn let to some more cleanup around function du_rlc_data_req().
After receiving GTP packets at the DU, they were given to the PDCP to
enqueue the packet at RLC. This does not work anymore, since the PDCP is
not initialized; it also does not seem necessary, as this enqueue
functionality is necessary to decouple PDCP and RLC to avoid deadlocks
in monolithic, but in split-mode, this cannot happen. Instead, call
directly into the RLC when receiving GTP packets.
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: 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
NR UE: Enable additional PDU session
- fix a bug with wraparound of buffer_remain_ep
- Add --extra-pdu-id command line option
Testing procedure:
1. Start cn in openairinterface5g/doc/tutorial_resources/oai-cn5g with
docker compose up
2. Start gnb:
sudo ./nr-softmodem -O ../../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.fr1.106PRB.usrpb210.conf --gNBs.[0].min_rxtxtime 6 --rfsim --rfsimulator.server_address server
3. Monitor extra interfaces being created:
watch -n 0.5 "ifconfig | grep tun"
4. Start UE:
sudo ./nr-uesoftmodem -C 3619200000 -r 106 --numerology 1 --ssb 516 --band 78 --rfsim --uicc0.imsi 001010000000001 --extra-pdu-id 11
5. An extra tun interface oaitun_ue1p11 should be created. Observe in
the terminal from step 3
6. Ping the core network from both interfaces, e.g., ping -I
oaitun_ue1p11 10.0.0.1, ping -I oaitun_ue1 10.0.0.1. This should
generate traffic on the gNB on different LCIDs.
Measurement gaps
Scheduling measurement gaps to provide sufficient time for the UE to
re-tune its transceiver to the target carrier, complete the set of
measurements and then re-tune its transceiver back to the original
carrier.
fix(RLC): Count dropped DL SDUs by the RLC
When a downlink SDU was discarded by the RLC Acknowledged Mode entity
due to a full transmit buffer (tx_maxsize), the drop statistics were not
being updated. The txpdu_dd_pkts and txpdu_dd_bytes counters remained at
0. It should be noted that while the statistics are named txpdu_dd_*,
the drop at this stage occurs at the SDU level.
speedup NR RLC RX for AM
rx_list is replaced by an array of size 2^(SN size - 1) which is 131072
for an SN size of 18 bits, leading to 1048576 bytes of memory used.
(Less for smaller SN sizes.)
A lot of RX processing was to run through rx_list. When the list was big
(with some non-ideal channel), it can take some time. Removing this list
should improve things. Checking with benchmark_nr_rlc_am_entity a
speedup of more thant x10 is achieved (except for the case 1024 which is
surprisingly faster than the others in the develop branch).
The only thing that may be slower is when looking for cur->next where
the SN is different, in which case we need to look for all SN one by one
until we find something or reach the limit (rx_highest_status). These
are the functions get_first_rx_pdu() and get_next_rx_pdu().

Add WLS as a transport option for VNF/PNF, refactor existing options
This MR adds a new transport mechanism for the VNF and PNF split, using
the Intel WLS library, which makes use of DPDK and shared memory to
transport messages. This transport mechanism is what is used to
interface with Radisys ODU, while also working with OAI VNF/PNF.
The VNF and PNF have been refactored so that the transport-specific
functions are isolated from the rest of the logic, and as such,
interchangeable by means of function pointers.
The same change is done for the packing/unpacking procedures, allowing
to switch between FAPI and nFAPI encoding.
This MR also reduces the amount of duplicated code, by refactoring the
VNF with Aerial, which now only has the transport-relevant functions, as
well as the ones that are unique to it ( for example, the unpacking
procedures where a secondary data buffer is used for the message
payloads )
Additionally a new callback is added to the VNF to process
ERROR.indication messages, which currently only indicates which message
originated the error, and which error occurred.
Get xran stats in the trx_oran_get_stats function
and use trx_oran_get_stats upon stopping and ending RF.
Co-authored-by: Romain Beurdouche <romain.beurdouche@eurecom.fr>
Look up xran_fh_init/xran_fh_config through driver instead of peaking
into xran internals. Note that xran writes values back into these
structs during initialization, and hence it is important to store them
_after initialization_.
Some remarks regarding less obvious changes:
- slotnum is replaced by slots_in_sf: SLOTNUM_PER_SUBFRAME uses the time
duration of a slot (=interval_us_local) to calculate the numbers of
slots in a subframe, which can be done with a simple shift instead
- The prach duration should be queried from the PRACH configuration
table. The function to query the occasion info is part of the MAC
layer code while this information can be used outside of this layer.
Use header `nr_prach_config.h` to not duplicate functionality.
Co-authored-by: Romain Beurdouche <romain.beurdouche@eurecom.fr>
The buffers are set up by the OAI xran driver, so instead of peaking
into xran internal data, access the buffers through the driver directly.
The buffers get set up through the following xran calls
In xran_5g_fronthault_config():
- src => sFrontHaulTxBbuIoBufCtrl
- srccp => sFrontHaulTxPrbMapBbuIoBufCtrl
- dst => sFrontHaulRxBbuIoBufCtrl
- dstcp => sFrontHaulRxPrbMapBbuIoBufCtrl
In xran_5g_prach_req()
- prach(dst) => sFHPrachRxBbuIoBufCtrl
- prach(dst)decomp => sFHPrachRxBbuIoBufCtrlDecomp
Note that in all cases:
- the xran buffer array is [XRAN_N_FE_BUF_LEN][XRAN_MAX_SECTOR_NR][XRAN_MAX_ANTENNA_NR]
(of [internal] type BbuIoBufCtrlStruct, but we give an sBufferList)
- the driver buffer array is [XRAN_MAX_ANTENNA_NR][XRAN_N_FE_BUF_LEN]
Hence, we switch the order of indexing, leave out the sector, and omit
the sBufferList member.
xran_get_slot_idx_from_tti() has been introduced to access data
information from xran. However, it makes no sense, as the used macros to
calculate frame, slot, subframe, are already in the public API. Hence,
use these macros directly.
It would be possible to remove xran_get_slot_idx_from_tti(), but doing
so we would need to update the patch ID, causing trouble to users.

continuously update SIB19 information for rfsim NTN LEO scenarios
Contains mainly these changes:
- gNB: add function nr_update_sib19() allowing to update SIB19
information
- rfsimulator: update SIB19 contents every frame for LEO channel
simulations
- NR UE: improve initial timing advance calculation from SIB19
Before, we only considered ta_Common_r17 and the SAT position from SIB19
to compute the initial timing advance value. This is good enough if the
satellite does not move too fast (e.g. GEO satellite).
Now we also consider ta_CommonDrift_r17, ta_CommonDriftVariant_r17 and
the SAT velocity together with the epoch time from SIB19. This improves
the accuracy of the initial TA computation, esp. for LEO satellite
scenarios.
Various fixes for UE handling, HO doc updates
- On release request, search both attach and connected list to free a UE.
- on DU disconnect, only release the correspnonding UE contexts.
- When no AMF for the UE, auto-release the UE (NGAP would also send an
answer, but better check first)
- implement a "grace period" before the DU/MAC automatically releases a
UE: this is to avoid cases in which (for whatever reason) the UE
release request is not honored by the CU. In order to not fill up UE
contexts unnecessarily, the DU will eventually (after 10s) drop the UE
context
- some clarification in HO tutorial
When the RA procedure fails at Msg4, we trigger UL failure and send a
message to the CU to request release. There was a bug in that upon the
ensueing release command, we did not search in the attach list (only
connected list). However, the UE failing at Msg4 does not have
transitioned to the connected list yet, thus not freeing the context.
Fixes: 8f62baefa6 ("Use list of UEs during RA instead of array of RA
processes)"
It might happen that the CU does not answer a release request. In that
case, the MAC would never free the UE context, potentially blocking the
DU. Avoid this by introducing a "grace period" after which a UE context
is automatically freed at the MAC (and RLC), currently at 10s after the
30s UL failure timer.
Mark non-existing AMF UE NGAP ID through invalid INT64_MAX number
(permitted range is up to 2^40-1). Check for this range in the RAN
function, as we might otherwise pass the invalid AMF UE NGAP ID to the
agent, which would assert with
nr-softmodem: /oai-ran/openair2/E2AP/flexric/src/lib/3gpp/enc/enc_gnb.c:83: enc_gNB_UE_asn: Assertion `gnb->amf_ue_ngap_id < 1UL << 40' failed.
In other words, don't send KPM messages for a UE which has no valid AMF
UE NGAP ID yet (which follows from the fact that the spec requires an
AMF UE NGAP ID; the previous behavior of simply sending 0 could be
considered a bug, because it's not the UE's true AMF UE NGAP ID).
NR RRC Reject UE
Improvements in procedures to handle RRCReject message both at gNB and
UE. At gNB we send RRC Reject if the UE cannot be given resources to go
into connected mode.
bugfix: read msg_type only after deciphering
There was a problem with accessing msg_type from the input buffer before
deciphering, giving obviously wrong value.
CI team: we should add a test in the CI with NAS ciphering + integrity
(connection to the core) set to not null (I suggest nea2/nia2). With
openair's core, this is done by setting this in the amf config file
(nia1 and nea2 at the top of the list):
supported_integrity_algorithms:
- "NIA2"
- "NIA1"
- "NIA0"
supported_encryption_algorithms:
- "NEA2"
- "NEA1"
- "NEA0"
And also put full security in the AS. This is done with this in the gnb
config file:
security = {
ciphering_algorithms = ( "nea2", "nea0" );
integrity_algorithms = ( "nia2", "nia1", "nia0" );
drb_ciphering = "yes";
drb_integrity = "yes"
};
Ideally we should test this with both openair UE and cots UE. But as a
strict minimum do for openair UE (this is where the bug was).
No need to do much traffic, a few ping is enough. But if you want to
check throughput with full security, why not.
Remove this option: some tests produce an excessive amount of output on
failure (e.g., googletest/benchmark). This seems to overwhelm the Python
CI code. Suppress this output, because we can always manually run this
test. A high-level "this test is ok/nok" should be fine for the CI.
NR UE: enable CSI report for SISO case
Correct precoded_sinr_dB wrongly set to 0 for SISO case, also correct
ri_restriction is 0 when calculating CQI bit length for SISO.
Update/refine gNB MAC stats, update L1
Only applicable with -q option.
Print a number of statistics, e.g., rx_ulsch_sdu to track UL MAC stats
timing. Remove unused time_meas_t definitions, and fix the name for the
total gNB scheduler time.
Print the RU stats in nrL1_stats.log, as some are already there, and do
not "pollute" the periodic logs when -q is enabled.
I used this to see why there are sometimes late slots with Aerial. I
used the above stats to get a general overview. This additional patch
shows that at least in RFsim, the RLC indication in rx ulsch sdu can
take up to 20us on my machine. Given that we can have multiple PDUs in
UL (10?), this can amount to a sizeable amount of time. While this is
for another MR, I thought the cleanup would be nice to have.
Do not pollute periodic output, and rather print those into
nrL1_stats.log. A number of them are already there anyway, so transfer
the rest. Note: ru->ifdevice.tx_fhaul is omitted, as we don't have any
IF5 split in 5G.
Refactor F1 UE context messages, add unit tests
Add encoder+decoder+util functions for F1 UE context messages, and use
them in the stack. The overall goal is to unit test encoder+decoder (to
be sure that what we send is what we receive), and remove any memory
leaks related to F1 handling. Messages that have a unit test:
- F1 UE context setup request/response
- F1 UE context modification request/response
- F1 UE context release request/command/complete
This MR removes almost all remaining memory leaks that are observable in
a "standard" configuration, running SISO in RFsim. In RFsim (without
channel modelling), there are only two memory leaks shown in asan, one
in L1, and one in NGAP.
Speed up docker deployment in CI
- Using docker compose up --wait instead of a custom healthcheck script:
from: https://docs.docker.com/reference/cli/docker/compose/up/
--wait Wait for services to be running|healthy. Implies detached mode.
--wait-timeout Maximum duration in seconds to wait for the project to be running|healthy
- Speeding up the healthchecks by reducing the interval from 1-10s to
0.5s during start period
start_period creates a special period after the start of the container
where the healthcheck is executed every start_interval . During this
time the failures do not count towards the retries counter, but
successes change the status to healthy. This allows container to reach
healthy status much sooner.
- Using init: true to speed up docker compose down/stop
`init: true` initializes the docker container with tini or
alternative: tini is used to collect all the processes and correctly
pass the termination signal to them. This allows the docker container
to be stopped without waiting 10 seconds to kill the container
- Smallest example of this is:
services:
test-init:
image: ubuntu:jammy
command: sleep 10d
We use the same resource for CSI meas report and RSRP (judging by the
name of the functions), but the memory allocations need to be separate
to avoid a double free:
