These libraries have an (indirect) dependency on T, either by using the
logging module (which in turn depends on T), or through other includes.
The easiest is to depend on the logging module, which will fulfil also
the T dependency.
It would equally be feasible to use the utils target (which in turn
depends on log_headers), but this would necessitate to compile, and does
not seem to be necessary.
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.
Remove, because
1) it does not compile (the asn1c generated code should be prepend with
LTE_ etc, nobody did that)
2) a shared module makes no sense
3) the configuration is trivial to recreate
Link E2_AGENT libraries directly into nr-softmodem/lte-softmodem instead
of L2/L2_NR/F1AP. Doing that ensures that simulators, e.g.,
nr_dlsim/nr_ulsim do still compile. It also simplifies the code.
Prior to this, compiling nr_ulsim with E2_AGENT, for instance, resulted
in the following errors, fixed in this commit:
FAILED: nr_ulsim

Align add_boolean_option as per CMake documentation use only ON/OFF for uniformity
The add_boolean_option of CMake is not uniform everywhere. We were using
either True/False or ON/OFF. It is better to be uniform to avoid
confusion.
As an example, see here CMake documentation for an example:
https://cmake.org/cmake/help/latest/module/CMakeDependentOption.html#example-basic-usage
There are also some minor spelling corrections.
some work for better interoperability with srsRAN DU
Just add the minimum to get some user plane traffic going on.
When doing user plane traffic, in the CU logs we have a lot of:
[GTPU] NR-RAN container type: 1 not supported
That will be fixed in another MR, not here.
Add a CU-UP load tester and improve GTP performance
This adds a simple tester program for the CU-UP. It sets up a number of
UEs/bearers in the CU-UP via the E1 interface, then streams data in
downlink/uplink (as seen by the CU-UP). More information is available in
tests/nr-cuup/README.md.
Includes some fixes to properly verify that SCTP is installed, and use
"the right cmake way" to use it in cmake code (see commit for details).
This is a simple CU-UP load tester. It sets up a configurable number of UEs in the
CU-UP, then sends GTP traffic in downlink/uplink in the N3-F1/F1-N3
direction at the CU-UP. It then compares the sent and received data.
Additional parameters, such as amount of traffic, test length, packet
size, and IP addresses/ports are configurable.
To run:
mkdir build && cd build && cmake .. -GNinja && ninja nr-cuup nr-cuup-load-test params_libconfig
./tests/nr-cuup/nr-cuup-load-test
./nr-cuup -O ../tests/nr-cuup/load-test.conf
The tester should be able to detect lost and reordered packets.
Example lost: Receive order 2,3,5,6 (lost packet 4)
=> on packet 2, expected 2, next=expected+1=3
=> on packet 3, expected 3, next=expected+1=4
=> on packet 5, expected 4, diff=5-4=1 (lost 1), next=payload+1=6
=> on packet 6, expected 6
=> 1 lost
Example reordered: Receiver order 2,5,3,6 (lost packet 4)
=> on packet 2, expected 2, next=expected+1=3
=> on packet 5, expected 3, diff=5-3=2 (lost 2), next=payload+1=6
=> on packet 3, expected 6, (reduce lost by 1 to 1), next=expected=6
=> on packet 6, expected 6
=> 1 lost
Example reordered: Receiver order 2,5,3,4,6 (no losses)
remove specific directory for LTE SIM management tools
This is very old code has never been integrated with the "main" OAI
cmake infrastructure and more recent libraries.
This MR integrates the three binaries for LTE virtual sim management in
the regular build process and log system
Remove sctp from all other targets, since we use sctp::sctp on
SCTP_CLIENT (would fail if it does not exist), and SCTP_CLIENT already
fulfils the SCTP dependency.
Move the path to the beginning, so that we can use it early.
Specifically, it was after the SCTP module, and the next commit will use
the Findsctp.cmake module to find SCTP. Use the cmake-proper variable.
Add check to vnf_nr_handle_param_response for when phy_info is not found
The WLS VNF is in charge of Enqueueing the used blocks after usage for transport, this is done by keeping track of all blocks used, and calling WLS_Enqueue for all of them upon receiving a SLOT.indication
The common library exposes functions for the PNF to return the received blocks to the VNF for it to call WLS_Enqueue on them.
This is done in order to ensure the Blocks are returned after processing, also preventing the Dequeueing of blocks that are still being used, i.e. the internal value is not -1
All saved blocks are to be enqueued at the reception of a SLOT.indication by the VNF
Additionally, the definition of NFAPI_MAX_PACKED_MESSAGE_SIZE was moved to nfapi_interface.h and removed from the other headers, this is done to allow to set the maximum message size when using WLS by only changing the value in one place
Fixup fapi_nr_message_header_unpack call in nfapi_hex_parser
[E2 agent] E2AP README update and OAI-FlexRIC CI pipeline improvements
- E2AP README - add OSC nearRT-RIC section; update with proper FlexRIC
links, and explanations on prerequisites, as well as for xApps
- OAI-FlexRIC CI - use separate containers for xApps
- add reference files for CU-UP/CU-CP
- add logging for KPM NSSAI condition
A number of radio-related RRC parameters, e.g., CellGroupConfig,
"originate" at the DU and are sent to the CU for forwarding to the UE
only. Similarly, there are additional parameters, e.g., RLC-BearerConfig
(part of CellGroupConfig), that originate at the DU.
Hence, the DU decides about these parameters, depending on the MAC state
and capabilities. To clarify this, move the existing
openair2/RRC/NR/nr_rrc_config.{c,h} => openair2/LAYER2/NR_MAC_gNB/nr_radio_config.{c,h}
So that developers know that while those are RRC parameters, they
originate at the DU.
In other words, the CU/RRC is not supposed to use any of these functions
in the RRC. Correspondingly, includes of this file have been cleaned up
(and when they are not necessary at the MAC as well).
Add physim tests into ctest framework
Convert physim testcases listed in
cmake_targets/autotests/test_case_list.xml into ctest. Note: Tests for
dlsim_tm4 are excluded, due to compilation issues.
CTest evaluates success based on return code: '0' = pass, non-zero =
fail. For some simulators, the return code is non-zero even when the
test is successful (as indicated by success messages in the test logs).
For some simulators, the return code is always '0'. This inconsistency
has been address in the first two commits of this MR.
To build and execute these tests:
- using cmake
cd openairinterface5g
mkdir build && cd build # you can also do that in cmake_targets/ran_build/build
cmake .. -GNinja -DENABLE_PHYSIM_TESTS=ON && ninja tests
ctest
- using build_oai: physim-related ctests are activated when PHY
simulators are built (use build_oai with '-P' or '--phy_simulators'
option)
cd openairinterface5g/cmake_targets
./build_oai --ninja --phy_simulators
cd ran_build/build
ctest
Link to newly created 4g and 5g RAN-Physim-Cluster pipelines:
- RAN-Physim-Cluster-4G: https://jenkins-oai.eurecom.fr/job/RAN-Physim-Cluster-4G/
- RAN-Physim-Cluster-5G: https://jenkins-oai.eurecom.fr/job/RAN-Physim-Cluster-5G/
Convert physim testcases defined in cmake_targets/autotests/test_case_list.xml
into CTest based tests. These test are activated when '-DENABLE_PHYSIM_TESTS=ON'
CMake flag is set.
Note: Tests for dlsim_tm4 are excluded, due to compilation issues.
CTest evaluates success based on return code: '0' = pass, non-zero = fail.
The following table outlines the physim executables, their success expressions
(`expr_true`), and the return codes for success (`ret_success`) and failure
(`ret_fail`). The `expr_true` is used in test_case_list.xml to check for test
results.
| test_exec | expr_true | ret_succ | ret_fail |
| ------------- | -------------- | --------------- | ----------------- |
| dlsim | passed | 0 | -1 |
| ulsim | passed | 0 (ret) | 1 (ret) |
| ldpctest | BLER 0.000000 | 0 | 1 |
| polartest | BLER= 0.000000 | 0 | 1 |
| nr_pbchsim | PBCH test OK | 0 | 1 |
| nr_dlsim | PDSCH test OK | 0 | 1 |
| smallblocktest| BLER= 0.000000 | 0 | 1 |
| nr_ulschsim | PUSCH test OK | 0 (n_errors) | n_errors |
| nr_pucchsim | PUCCH test OK | 0 | 1 |
| nr_ulsim | PUSCH test OK | 0 (ret) | -1 (ret) |
| nr_prachsim | PRACH test OK | 0 (prach_errors)| > 0 (prach_errors)|
| nr_psbchsim | PSBCH test OK | 0 (errors) | > 0 (errors) |
Add CMake flag "ENABLE_PHYSIM_TESTS=ON" when building OAI with "-P"
or "--phy_simulators" option. This allows physim-related ctest to
be executed from build directory.
Add dependency on coding lib for all 4G physims
The functions nr_generate_csi_rs() and nr_ue_generate_csi_rs() are
identical. This commit removes nr_ue_generate_csi_rs() and moves
nr_generate_csi_rs() to nr_phy_common_csirs.c so both gNB and UE can use
the same function.
