DCI 00 alt size fix
DCI size for format 00 and 10 should be equal so we need to compute the size of
the alternative format when computing the size of DCIX0. There was a bug where
the alt_size input (0 in that case) was taken into account also when computing
that alternative size, resulting in an alt_size of 0. Possibly easier to
understand by looking at the code then reading this description.
SDAP: guard RX header parsing with enable_sdap and init per-entity
!3519 (merged) refactored the SDAP to use the QFI from the header rather than
pass it to the rx function and got rid of the initialization of QFI to -1.
However, entity roles are stored into the drb2qfi table, and the indexing
implies that the QFI is known.
While in TX it is not an issue since packets are forwarded based on the QFI,
in RX the QFI can only be parsed from the header, therefore if headers are
disabled (--enable_sdap) the QFI is not there and it is wrong to access the
header (buf[0]) and looking for it.
This commit adds enable_sdap to nr_sdap_entity_t and initialize it in
nr_sdap_add_entity() from sdap->role (disabled when NO_SDAP_HEADER).
In nr_sdap_rx_entity(), only parse buf[0] for QFI and derive sdap_ul_rx/
sdap_dl_rx when enable_sdap is true; otherwise, keep offset=0 and forward
payload unchanged.
NTN: Fixing variable ULDLduplex issue for NTN bands
- Duplex is assumed to be static but for NTN bands (and also for some non NTN
bands), it is not static.
- Tx-RX Duplex is defined in section 5.4.4 of 38.101-5 (for NTN) specs v1809
- For example: In NTN-OTA testing, the GEO satellite operator configured in
band 256 the DL, UL frequencies with duplex of 185Mhz.
!3519 refactored the SDAP to use the QFI from the header rather

However, entity roles are stored into the drb2qfi table, and the

issue since packets are forwarded based on the QFI, in RX the QFI
can only be parsed from the heaedr, therefore if headers are
disabled (--enable_sdap) the QFI is not there and it is wrong to
access the header (`buf[0]`) and looking for it.
This commit adds `enable_sdap` to `nr_sdap_entity_t` and initialize
it in `nr_sdap_add_entity()` from `sdap->role`
(disabled when `NO_SDAP_HEADER`). In `nr_sdap_rx_entity()`, only
parse `buf[0]` for QFI and derive `sdap_ul_rx`/`sdap_dl_rx` when
`enable_sdap` is true; otherwise, keep `offset=0` and forward
payload unchanged.

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

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
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
This commit inputs several distances at once and obtain the summary of
successful and failed tests. We look for the number of successful tests
that are geater than 0. We do that here since we sometimes dont receive
a response for a telnet command from the rfsim although the command
is applied. This is related to the queing telnet commands in the rfsim.
The script for the distances 50, 100 and 150 are called as follows,
./set-and-verify-distance-prs.sh 50 100 150
The summary can be viewed as follows,
==================== SUMMARY ====================
Total tests run : 3
Successful tests: 3
Failed tests : 0
=================================================
Set RFsim (DL) distance and use PRS to estimate the new distance. This
is verified by comparing the distance set in RFsim with the distance
reported through ToA estimation at the UE.
Note that since RFsim telnet output is asynchronous (it uses a queue
internally), we use grep --max-count 1 to wait for the matching line,
together with ncat --idle 0.3 to keep ncat open for some time. The
--max-count option will terminate grep after the first occurrence. For
this to work reliably, we need to use grep <(echo | ncat) as opposod to
simply echo | ncat | grep, as the latter does not seem to reliably
make grep exit after the occurrence.

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.
Handle SIGINT and mark any subsequent steps as failed. Receiving SIGINT
a second time will abort the script immediately (as is the case before
this commit).
Note that Python seems to relay the signal to the "controlled" process
(e.g., Ping), which would return immediately with an error. So some
steps like Ping will abort immediately, others (e.g., IdleSleep) will
finish their step, and then the present logic will mark subsequent steps
as failed.
Some CI tasks/commands like Iperf(), Ping() get multiple nodes (via XML
parameter "nodes") to potentially run UEs on different nodes (hosts) at
the same time. However, I argue that this is not good:
- we don't actually use this -- where we specify multiple UEs, it's
always "localhost localhost..."
- it is inconsistent, as we typically have a single "node", not nodes,
and there is a possibility to harmonize (see also next commit)
- if we needed it, there would be better ways to achieve the same.
First, for hardware-based UEs, the ci_infra.yaml can specify different
UEs. For simulated UEs, it would be feasible to have multiple XML
steps run in parallel, e.g., in the XML <parallel> tag, which would
clarify that multiple UEs on different hosts run in parallel
- it reduces code.
Hence, make a single <node> for these XML steps.
Created Jenkinsfiles:
- Jenkinsfile: for stadard test pipelines
- Jenkinsfile-oc: for deployments with OC
These 2 Jenkinsfiles covers all current test pipelines.
Previously, we were using int16_t for the variable ch_tmp which was later harmonized to use c16_t while leaving <<1. This introduced the bug while accessing the address of the element at first_half of the ch_tmp variable.

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.
Refactor DLSCH scheduler
Refactor the DLSCH post processor similarly to what has been done in
!3521 with the goal of saving an additional iteration through all UEs,
hopefully making the DLSCH scheduler faster.
It further includes changes to make working with and debugging multi-UE
operation easier:
- add some measurements in L1 (for total TX/RX time)
- a new option MACRLCs.[0].stats_max_ue to limit the number of UEs in
the periodic output (default: 8, 0=disable)
- avoid stack overflow in the MAC
- fix the writing of stats to nrMAC_stats.log and nrL1_stats.log when
the written output reduces by truncating the files
- avoid to schedule retransmission with 0 RBs.
This slightly speeds up the scheduler (it e.g., does not need to check
for UEs that have retransmissions), and harmonizes with pf_ul(), which
evaluates (UL) BSR at a similar place within the scheduler.
Check and return, if necessary, that we have enough resources to make
retransmissions. Without, we can asserts in L1, such as
Assertion (NPRB>0 && (NPRB + RBstart <= BWPsize)) failed!
In PRBalloc_to_locationandbandwidth0() openairinterface5g/common/utils/nr/nr_common.c:506
Illegal NPRB/RBstart Configuration (0,51) for BWPsize 51
which indicates that the scheduler requested a transmission with 0 PRBs,
which does not make sense.
