CI: Enable Physim threshold check for tests on Caracal and GH
This MR adds support for configurable timing threshold files in PhySim
tests.
- Introduces a new CMake cache variable PHYSIM_CHECK_FILES to specify
one or more timing threshold files (semicolon-separated).
- Enables optional enforcement of timing thresholds check in PhySim
tests without changing existing test definitions.
- Defines timing thresholds for LDPC encoding/decoding in nr_ulsim,
nr_dlsim and ldpctest on Caracal and GH machines.
SRS noise power
This MR implements the calculation of the noise power based on SRS in a
different way, and check whether SNR is more accurate or not. This MR is
built on top of the MR: !3460
A graph was added in T_Tracer to observe UL-SNR calculated using SRS.
See merge request description for measurement results.
Replace the previous add_timed_physim_test() macro with add_physim_test()
to use a single, unified function for defining physim tests. This simplifies
the test configuration and removes redundant macro definitions while keeping
all existing functionality.
This change follows up on the earlier addition of support for including
custom timing threshold files (PHYSIM_CHECK_FILES).
Update existing tests accordingly.
For some physical simulators, we have multiple SNR iterations.
The previous version of the script correctly retained only the last
measurement, but if a previous measurement condition set RC=1, the
script would fail although the final "good" run might fulfil the
measurement condition (IOW, it would show SUCCESS, but still fail on the
check).
Instead, check if all measurement lines finish on SUCCESS, which handles
the above case.
The awk script in analyze-timing.sh used syntax that works with gawk but fails
on systems where mawk is the default implementation, producing errors such as:
awk: /dev/fd/3: line 6: syntax error at or near ,
-- test command finished with SIGPIPE
Concretely, the match(text, pattern, variable) function does not exist
in mawk, as it cannot capture matches in variables. Work around by
substituing strings, and force a numeric comparison.
fix RSRP computation at UE
Conflicts between !3595 (merged) and !3596 (merged) leading to double conversion
of RSRP into index in L1 and L2. With this fix it is only converted in L2.
Make all targets compile
This MR enables us to compile all targets, and does that in one CI test. This
closes#726. Now, this should work:
cd ~/openairinterface5g
mkdir build && cd build
cmake .. -GNinja && ninja
To achieve this, I did the following:
- some targets have been fixed (warnings, errors)
- some targets have been removed when they did not seem to serve a good purpose
(e.g., an almost empty test)
- some targets have been commented (e.g., LTE simulators, some unitary tests)
which we maybe want to revive in the future
- some targets built when just building with ninja, but not all. For instance,
telnetsrv_enb would typically build, but it was missing a dependency. Doing
cmake .. -GNinja && ninja telnetsrv_enb would show this (in develop)
To help with the last bullet point, there is a script compile_targets.sh that
can compile targets independently (and in parallel, to not wait for ages) to
show that targets compile properly compile-targets.patch.
In almost all cases, the problem is that a specific module uses the logging
module, which depends on T, which needs to dynamically create headers. The way
to do this is to have a dependency, and many targets use generate_T or {T_LIB}
({} intentional: T might be absent, so then it evaluates to nothing). However,
not all do this, and those that depend on T actually don't depend on T, but on
the logging module, which in turn depends on T. So in many places, a simple
dependency onto log_headers fixes this problem, and generate_T or {T_LIB}
simplifies the dependency (but not always). The commits should have more info.
Note that at least the targets in FlexRIC do not all compile, at least in the
configuration that we use in docker/Dockerfile.build.ubuntu. So for the latter,
we cannot build with a simple ninja, but FlexRIC seems to be the only one that
does not compile. Since FlexRIC is a separate repository, that needs to be
addressed in the corresponding repository.
NR UE: add UCI (HARQ-ACK/NACK) on PUSCH support at PHY
Add UCI (HARQ-ACK/NACK) on PUSCH support at nrUE PHY, the multiplexing procedure
can be found in TS 38.212 section 6.2.7.
Verified with 3rd-pary gNB for cases when HARQ payload bits length is 1, 2 or 3.
Closes#959 and #967 .
Since there is no UCI on PUSCH implementation in gNB, it is good to test
UE's implementation with matlab.
This commit allows to test with matlab in two ways:
1. generate OFDM waveform from ulsim and decode it in matlab using
uci_on_pusch_decode.m
2. generate codeword in matlab using uci_on_pusch_encode.m read it in
ulsim and compare the bits. ulsim option -o is used
When the codeword has UCI multiplexed with data, we need to handle UCI scrambling according to 38.211 section 6.3.1.1.
Especially when O_ACK <= 2 there are x and y placeholder bits for UCI.
Get beta offset, alpha scaling and other parameters to calculate rate matching information for UCI on PUSCH,
then use the rate matching info to encode UCI and re-encode PUSCH, call nr_uci_on_pusch to get final multiplexed codeword for scrambling.
coding_defs.h included defs_common.h, which pulls in many dependencies,
e.g., the logging module, which pulls in T. However, it does not use
anything of this. So remove, and include stdbool.h instead (because bool
is used in coding_defs.h.
nr_polar_defs.h relied on some includes done in coding_defs. Use
includes for pthreads and SIMD to define types that are used in
nr_polar_defs.h.
This constant seems to be an analogon to NUMBER_OF_UE_MAX; replace with
the latter, as it does the same. (NBIoT does not work, anyway)
Fix dependencies of the NB_IoT target so it compiles.

Data and control multiplexing procedure is defined in 38.212 section 6.2.7.
Step 3 (CSI1 and CSI2 mapping) is not implemented, only HARQ-ACK.
PUSCH frequency hopping is not supported.
Use betaOffset and alpha scaling etc. to get rate matching information of UCI on PUSCH (e.g. max bit capacity of encoded UCI and encoded ULSCH)
according to TS 38.212 section 6.3.2.4 and 6.2.7.
38.212 section 5.3.3.1 and 5.3.3.2 describe how to encode 1-bit and 2-bit information.
This is needed when typically HARQ-ACK will be transmitted on PUSCH.
38.212 section 5.4.3 also describes how to do rate matching for channel coding of small block lengths.
