Create Debian and Redhat packages with CPack
Use CPack in CMakelists in order to create packages, creation command is
available in build_oai script and options description is available in
packages.md
Packages must have a name, a version, a section, an architecture, a maintainer, a description (long and summary), dependencies
Shared libraries must be stripped, have soversion, version (debug symbols are found in separate packages), since MODULE is used instead of SHARED it works as a plugin library which is opened using dlopen-like functionality, see: https://cmake.org/cmake/help/latest/command/add_library.html
Packages must have postin and postun scripts
Since it is not recommended to modify CMAKE_EXE_LINKER_FLAGS, cmake's path variables are used : https://discourse.cmake.org/t/how-do-i-replace-the-compiler-options-for-one-target/7815/5
NGAP: improve error handling in RRCReconfiguration from Handover Command decoding
This MR refactors doRRCReconfiguration_from_HandoverCommand for consistency and
safety, and enables NGAP Handover Cancel encoding/decoding.
- Refactored doRRCReconfiguration_from_HandoverCommand function:
- Changed signature to return byte_array_t instead of taking a buffer parameter
- Prevents buffer overflow by auto-sizing memory with uper_encode_to_new_buffer
- Input validation
- HandoverCommand structure validation
- Error handling and cleanup for encode/decode failures
- ASN.1 structure cleanup on all error paths
- Updated caller in rrc_gNB_NGAP.c: use new byte_array_t return signature,
added buffer cleanup with free_byte_array(), sends Handover Cancel to AMF on
decoding failure (source gNB)
- Improved error logging
- NGAP Handover Cancel encoding/decoding support
- Added missing Handover Cancel ack case handler for
NGAP_ProcedureCode_id_HandoverCancel in ngap_gNB_decode_initiating_message()
to decode and log incoming Handover Cancel Ack message
- Added NGAP_ProcedureCode_id_HandoverCancel to the list of supported
initiating message procedure codes in ngap_gNB_encode_initiating() allowing
the gNB to encode and send Handover Cancel messages
Note: The Handover Cancel procedure is already implemented elsewhere in the NGAP
stack; these changes complete support by ensuring the procedure code is
recognized in both encoder and decoder.
Closes#1043
UE support to send CSI report on PUSCH
Earlier work on UCI on PUSCH implemented only ACK/NACK. This MR extends that
to send CSI report too.
This branch is verified with MATLAB implementation for multiplexing CSI part 1
and part 2 on PUSCH. It is also verified with srsRAN gNB which successfully
decodes CSI part 1 on PUSCH.
Fix RSRP overflow
If UE L1 measure an RSRP = 0 it would report to L2 and RSRP value of -INT_MAX
dBm causing overflow in the qsort to determine the best RSRPs
Clear memory in shm_td_iq_channel after RX
Clear memory in shm_td_iq_channel after RX. This prevents the IQ
from being read twice. This can happen if the application crashes
and will keep the other side reading historical IQ samples.
Update vrtsim timing job thread
List of changes:
- avoid calculating accumulated rounding error by calculating absolute
sample index based on CLOCK_REALTIME every time.
- use threadCreate instead of plain pthread_create which assigns a unique
thread name and simplifies debugging
Use nr_get_csi_measurements() function to get CSI report for PUCCH and
UCI on PUSCH.
Harmonize filling csi report for UCI on PUSCH for periodic and aperiodic
CSI reports.

Standardize Documentation Formatting and Navigation for MkDocs
This merge request improves and organizes the documentation to align with MkDocs
requirements. The following guidelines have been applied:
Guidelines Followed
Fix Broken Links and Paths
- Updated all links with proper paths to ensure correct rendering in MkDocs.
Correct Headings
- Removed multiple H1 headings (#).
- Subheadings use H2–H6 (## to ######) for consistent structure.
Proper URL Formatting
- All URLs now follow standard Markdown syntax,
e.g., [Example](https://www.example.com).
Proper Syntax
- Tables, lists, and code blocks use standard Markdown formatting to ensure
correct rendering.
Remove HTML Formatting
- Removed unnecessary inline HTML styling from documents, retaining only the
content.
Notes and Warnings
- Converted notes and warnings into blockquote syntax (>).
This ensures the documentation is properly structured, consistent, and
MkDocs-friendly.
- Include functions/file_names in backticks for readability
- Include the images directly inside the document (rather than plain image file name)
- Give relevant spacing if required
- Remove multiple single top-level (# H1) headings per file
- Use (# H2 and ###### H6) sub-headings for consistency
- Remove any trailing # in the headings
- This ensures proper table of contents rendering in MkDocs.
- Also removed RUN_NR_multiple_BWPs.md as it is moved to MAC usage
- bold current status for clarity and add spacing for better readability
- Wrap processes in the test setup block inside code blocks as they were rendered as GitLab issues
- Remove extra spacing in the test setup block
- Give a line in between bullet points to reflect bullet points correctly
- Split long statement into bullet points for readability
- Format the document for proper rendering
- Fix table formatting
- Use standard TOC syntax in 5GNAS
- The parser was incorrectly interpreting `</` as the start of an HTML closing tag, leading to a crash in mkdocs
- Replace with HTML entity to ensure it is treated as a plain text.
NR gNB handling TCI state indication for beam switching
This MR implements the procedure to send in DLSCH MAC-CE for TCI state
indication to UE
- if new beam is reported via SSB RSRP, gNB allocates MAC-CE with TCI
indication
- DLSCH is scheduled to be transmitted with priority
- a timer is started when receiving ACK according to the delay mandated
by standard (8.10.3 of 38.133)
- at timer expiry the gNB switches beam
Check for PDSCH overlapping CORESET during RA
CORESET 0 is configured in the configuration file by
'initialDLBWPcontrolResourceSetZero' and PDSCH TDA list is configured based on
the current BWP size.
It may happen that the user configures a 2 symbol CORESET 0 for a BWP >= 48 PRBs
(which is a valid 3GPP configuration) but in function 'nr_rrc_config_dl_tda'
this scenario is not taken in account causing an overlap between PDSCH and PDCCH
symbols during RA.
This leads to very unreliable Msg2 and Msg4 decoding at the UE, but from time to
time it succeeds, which becomes hard to identify this issue.
closes#705
Fix two issues regarding vrtsims taps client implementation:
- Incorrect #define used to enable taps socket handling
- flatbuffers package name changing between ubuntu versions
