Trigger deregistration only in SA mode
Upon press of ^C, the UE triggers a NAS deregistration. This does not work
in do-ra or phy-test modes, because there is no NAS. Therefore, in non-SA
modes, just stop the UE directly.
This can potentially improve the 5G RFsim CI test case, because together with
a high RFsim timeout, the chances of the last HARQ status line being without
retransmissions is much higher. If that does not help, we can further increase
the retx threshold.

simplify the code and make the code more explicit, but the may structure
remain (nr_write_ce_ulsch_pdu interface is complex, merging it into the
called would make simpler and more interstandable code), fix some asserts
related to this part of code
Added support for NTN FDD FR1 bands 254, 255, 256 as specified in 3GPP TS 38.101-5
Conf files added for 15Khz, 5Mhz and 30Khz, 10Mhz configurations added for these bands
In some runs of a multi-UE deployment, we see segfaults because
cell_group->spCellConfig is NULL. We should not segfault in that case,
so check for spCellConfig.
When the UE list is full, the iterator will run through all
MAX_MOBILES_PER_GNB UEs. It expects that eventually the pointer is NULL,
which is not the case if we have MAX_MOBILES_PER_GNB (or it simply
depends on the following memory). So give one array entry more, to
ensure that the last one is NULL.
- add new data structures for antenna processing.
- create arrays that keep track of certain values (max_ch, noise_amp2, nest_count and delay) per each antenna. These values are processed in order to determine one final output.
- add time processing measurements for each antenna, and prints them in nr_ulsim.
- make num_antennas_per_thread configurable in nr_ulsim and the gNB config file.

UE: Set default SSB config
After initial sync the UE sets the ssb index bitmap in nrUE_config with
index obtained in initial sync. This allows UE to continue decoding PBCH
and stay synched with the gNB till SIB1 is received.
Replaced total_res with res_per_task when deciding whether to start a threadpool task or not.
This does not have big impact on the software as the nr_pusch_symbol_processing will recheck
ul_valid_re_per_slot anyway but it may reduce the number of thread pool tasks created.
Upon press of ^C, the UE triggers a NAS deregistration. This does not
work in do-ra or phy-test modes, because there is no NAS. Therefore, in
non-SA modes, just stop the UE directly.
If the RLC cannot retransmit a package, 3GPP specs say that we should
declare radio link failure (RLF). Up to this commit, the code did
nothing though. In this commit, add a per-UE RLF callback; the RLC will
call into this function to signal that RLF has been detected through
maximum retransmissions on a particular RLC bearer.

Extract nr_ra_procedures.c into a separate library and add a testcase for init_RA function.
The testcase redefines the following functions as stubs:
- nr_mac_rrc_ra_ind
- nr_write_ce_ulsch_pdu
- mac_rlc_data_req
- *lockGet_ul_config
- release_ul_config
- remove_ul_config_last_item
- nr_ue_configure_pucch
These stubs can be used to check init_RA behavior
CI: Cleanup of cls_physim.py
- Remove unused code and file
- Rework functions for CUDA and T2 log analysis
- Check if test was successful for nr_ulsim and nr_dlsim in
RAN-gNB-N300-Timing-Phytest-LDPC pipeline
Set SA mode as default
- Set standalone (SA) mode as the default.
- Adjust commands in Docker Compose files by removing --sa flags and
adding --nsa flags where applicable.
- Add a function to verify that only one mode is being used at a time.
- Update all relevant documentation.
In the last commits, SSHconnection class has been removed from
cls_containerize.py. We therefore don't need the username and password,
as cls_cmd uses certificates only. Remove the usage of the username and
the password, and harmonize the use of GetCredentials().
Recent refactoring replaced the CreateWorkspace function call with a
dedicated XML step (for clarity, and because it avoids needless
recreation of workspaces). In the proxy function, the same
CreateWorkspace xml step has been added, cloning the OAI RAN repo, when
we actually need the repository for the proxy. Hence, fix this by
calling the CreateWorkspace() function manually, but only when
necessary, to build the proxy. (It would only be a problem if the
pipeline would rebuild the proxy, which did not happen because not much
work is happening on the proxy repo).
Further, refactoring and simplication of the proxy build function were
done:
- never tag proxy with develop, that makes no sense
- overwrite CreateWorkspace() info after having created and used the
workspace (the "if" to build the proxy)
- simplify copying of logs
- add simple unit test
- remove check for ubuntu; the dependcy is "docker". Simplify the code
to not obscure with a class variable.
The first thing Build_Proxy does is to remove the repository. Further,
Build_Proxy does not use the OAI RAN repo, but the proxy repo. The
Create_Workspace() is therefore completely useless.
Remove CheckAndAddRoute(), as it is complicated to read, uses a
multitude of hostname/IP/password combinations. Replace with scripts on
the machines, which, as of this commit, are:
- porcepix: ~/after-reboot.sh
- ofqot: ~/after-reboot.sh
- nepes: ~/after-reboot.sh
- obelix: ~/how-to-resetup-obelix-out-of-reboot.sh
It is clearer in CI logs to use absolute paths, and that is also a
"preference" of the new SSH class (cls_cmd.py) in the sense that some
functions don't handle "cd" gracefully (because of underlying Python
library paramiko).
For zip, though, we should change to have nice relative paths in the
archives, so use cd <path> && zip ... to achieve that, instead of
changing to a directory. This way, the path on which we operate is still
visible in the logs in each line.
The clang build fails with
/oai-ran/openair1/PHY/MODULATION/gen_75KHz.cpp:16:23: error: variable length arrays in C++ are a Clang extension [-Werror,-Wvla-cxx-extension]
16 | complex<double> t[len];
| ^~~
/oai-ran/openair1/PHY/MODULATION/gen_75KHz.cpp:16:23: note: function parameter 'len' with unknown value cannot be used in a constant expression
So ignore this warning (and make the build pass), since OAI uses VLAs in
various places.
The previous version would put the user-defined options first. However,
the default options include e.g., -Wall. If a user tries to override
(see for instance the next commit) -Wall or other options might override
this and not honor the user choice.
To always have the user have the last work, put user-defined compile
options last.
THere are four possibilities, for the three options (phy_test, do_ra,
nsa):
- None is set -> SA
- Only one is set of each -> corresponding mode
Introduce a function softmodem_verify_mode() to check for these.
