CI: Change RU in Aerial setup from Foxconn to WNC
- Change frequency in the gNB config file, from 3.75GHz to 3.5GHz
- Add high throughput tests with may_fail tag (1Gbps in DL and 90Mbps in UL)
- Update Aerial tutorial to match the changes
Measurement gaps
Scheduling measurement gaps to provide sufficient time for the UE to
re-tune its transceiver to the target carrier, complete the set of
measurements and then re-tune its transceiver back to the original
carrier.
Add WLS as a transport option for VNF/PNF, refactor existing options
This MR adds a new transport mechanism for the VNF and PNF split, using
the Intel WLS library, which makes use of DPDK and shared memory to
transport messages. This transport mechanism is what is used to
interface with Radisys ODU, while also working with OAI VNF/PNF.
The VNF and PNF have been refactored so that the transport-specific
functions are isolated from the rest of the logic, and as such,
interchangeable by means of function pointers.
The same change is done for the packing/unpacking procedures, allowing
to switch between FAPI and nFAPI encoding.
This MR also reduces the amount of duplicated code, by refactoring the
VNF with Aerial, which now only has the transport-relevant functions, as
well as the ones that are unique to it ( for example, the unpacking
procedures where a secondary data buffer is used for the message
payloads )
Additionally a new callback is added to the VNF to process
ERROR.indication messages, which currently only indicates which message
originated the error, and which error occurred.
Add a section in nfapi.md related to the different transport mechanisms available for VNF/PNF communication
Edit NR_NFAPI_archi.md to describe the VNF and PNF processing logic, as well as adding a flowchart for each of the components execution
Add the necessary patch to install the WLS library in the system
Enabling usage of ulsyncvalidityDuration timer in SIB19
ntn-UlSyncValidityDuration in SIB19 from Spec 38.331 v17.12 A validity
duration configured by the network for assistance information which
indicates the maximum time duration (from epochTime) during which the UE
can apply assistance information without having acquired new assistance
information. The unit of ntn-UlSyncValidityDuration is second. Value s5
corresponds to 5 s, value s10 indicate 10 s and so on.
ntn-UlSyncValidityDuration-r17 ENUMERATED{ s5, s10, s15, s20, s25, s30, s35,s40, s45, s50, s55, s60, s120, s180, s240, s900}
Implementation of epochtime is under discussion.
It can be configured in configuration file according to the above
enumeration. For GEO - 240s, MEO - 20s, LEO-5s can be used.
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).
Tutorials: updates for NR SA Tutorials
- Update links for the latest Ubuntu 24.04.2 LTS iso file
- Update docker install to the latest instructions on the official
website
- Update UHD to v4.8.0.0
- Add support for 'default'/"empty" DNN to CN5G configuration file
* Add support for 'default' DNN to CN5G configuration file (that
will also be used when DNN is not available, "empty" DNN). This
configuration will allow most of the COTS UE to get PDUSession
without any APN configuration made by the user
* The 'default'/"empty" DNN configuration support was added in

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

Fix Liteon with MTU 1500 and update the FHI docs
- Closes#884 - needed to update the max fragments needed for
transmission of one symbol; technically, 5 are enough but due to wrong
equation in the xran F release we had to increase to 6
- Clarify packet length for VFs
- Update Foxconn doc and config file with MTU set for jumbo frames
- Update Benetel docs with new version v1.2.2
As per CUS spec, the MTU can be 1500 or 9000 B, where MTU = IQ data format.
Packet length = ethernet header + RTE_PKTMBUF_HEADROOM + MTU
However, xran assumes different definitions of the MTU:
(1) in xran_init_mbuf_pool(): MTU = ethernet header + IQ data format;
(2) in xran_get_num_prb_elm(), xran_init_PrbMap_from_cfg(), xran_init_PrbMap_from_cfg_for_rx(), xran_init_PrbMap_by_symbol_from_cfg(): MTU = complitely wrong (as the IQ data format is not well included).
Additionally, xran assumes that the max MTU 9600 B, instead of 9000 B as per spec.
Nevertheless, I left 9600 B in all config files and docs due to wrong calculation of (2) for the total number of PRBs per fragment.
1. Closes#884 - increase the XRAN_MAX_FRAGMENT from 4 to 6 (sufficient for MTU 1500 with compression 8b)
2. Add new firmware version that supports jumbo frames
3. Update the config file to align with the new Liteon unit in our lab - center frequency, jumbo frames, compression and RU MAC address,
as well as the max DL MIMO layers.
Add support for 'default' DNN to CN5G configuration file (that will also be used when DNN is not available, "empty" DNN). This configuration will allow most of the COTS UE to get PDUSession without any APN configuration made by the user
The 'default'/"empty" DNN configuration support was added in https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-amf/-/merge_requests/343
After capturing the FH packets, we observed that the RU supports the MTU value for jumbo frames.
Therefore, no fragmentation needed on DL.

Enable SSB-SINR based CSI reporting
3GPP 38.331 release 16 specifies that If the field reportQuantity-r16 is present,
UE shall ignore reportQuantity (without suffix). reportQuantity-r16 configures
SSB based SINR as the reporting quantity.
set do_SINR = 1; in gNB params part of the config file to enable SSB based SINR
reporting.
This commit refactors the TUN interface management by moving its creation
and configuration from the PDCP layer to the SDAP layer for UE.
Key changes include:
- Introduced `tun_generate_ue_ifname` and `tun_destroy` functions for better
TUN interface lifecycle management.
- Added support for creating and destroying UE-specific TUN interfaces in SDAP.
- Refactored `nr_pdcp_module_init` to remove TUN-related logic and moved it
to SDAP.
- Updated NAS and SDAP layers to handle PDU session-specific TUN interface
creation and configuration.
- Enhanced SDAP entity management to include TUN socket handling and thread
lifecycle.
- Updated NAS message handling to initialize default PDU session TUN
interfaces in NOS1 mode.
- Use a single SDAP thread function for gNB and UE
- Allow noS1 mode also in SA on gNB
These changes improve modularity by isolating TUN interface management within
the SDAP layer, aligning with the 3GPP architecture, and simplifying the PDCP
layer.
