Replace the unwieldy unix socket implementation of peer information
exchange with an authorative connection descriptor file that
informs the client of the connection method an number of antennas
on the server.
This allows the server to run without the client and allows the
client to reconnect as long as the server is running, as many times
as needed.
Move the channel state management outside the channel implementation.
This simplifies the channel implementation but forces users of the
channel to manage it's state manually.
Add handling for error states in vrtsim which allows to close the
softmodems with CTRL+C without hanging, improving user experience
- Client detection of stale timer.
- Abort state for client and server
Added a libary that can connect to a channel emulator and provide taps
as they are generated.
- Enable connection from vrtsim to channel emulation server
- Depends on flatbuffers definition file from raytracing-channel-emulator
- Depends on libanomsg-dev and flatbuffers-compiler (Ubuntu) or equivalent
- Added a compile time option ENABLE_TAPS_CLIENT to prevent other users
from being affected by additional dependencies
separate computation of size and value for DCI precoding information
This removes stuff that is only relevant for the gNB from the common
functions and moves it to the gNB scheduler functions (related to UL
precoding). In principle no functional change.
2 functions with same name as static to make it clearer they are separate.
remove unused copy of log_level global var.
remove threequarter sampling variable from the radio board general
configuration. The decision of sampling rate is made above. A better
behavior can be done later, like ask to the radio board what sampling
rate it can do,then use it to decide the appropiate sampling rate from
the gNB configuration. In UE case, it is another issue, as the sampling
rate would change after we decode SIB1, but also it is not developped
yet.
Think: NR with different number of slots per frame depending on mu.
The name 'subframes_per_frame' is a bit ambiguous. It is valid for LTE,
but for NR it should be 'slots_per_frame'.
For example, for sub-carrier spacing of 30KHz, we have 20 slots per
frame, so in this case subframes_per_frame = 20. In reality whatever
the numerology, there is always 10 subframes per frame in NR.
But how to name this variable which is used both for LTE and NR cases?
'subframes_or_slots_per_frame'? It's a bit long and also ambiguous.
Conclusion: no big deal I think. 'subframes_per_frame' and so be it.
- Allow client to exit cleanly if server is down
- Ensure timing_thread is joined only once avoiding exit_function loop
- Free noise_device
- Save previously sent samples for channel modelling

Closes#927 and #973
See merge request oai/openairinterface5g!3583
Add a simple RF emulator library with no real RF.
It only synchronizes the gNB with the real time clock.
It is to be used for stress test or benchmarking in phy-test mode.
Improve MAC docs for MCS and docker for BuildKit usage
See commits for details. The first one is for fixing an omission in
!3281, the second to clarify docker build usage.
Closes: #973
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()")
Many of these tests exit with an exit code != 0. Thus, the CI
automatically logs the result. Rather, write everything including stderr
to the file for analysis.
Also, rewrite the file with ">" instead of appending through ">>". While
appending works because the CI removes files after archiving, it seems
"cleaner" to remove files.
It is superseded by the CreateWorkspace() function and task step (which
removes and recreates a workspace), and this option was not actually
used in any function except for the build of unit tests, but no XML
step actually specified this option.
