- prerequisites - use the links to FlexRIC tutorial
- build FlexRIC - use the build tutorial from FlexRIC tutorial
- explain in more details the supported service model functionalities
- explanation if no RIC INDICATION is being sent
- use multi-UE rfsim tutorial from doc/, not oai-workshops repository
Segmentation fault occured since the commit ID 9e5c5497ab,
where we try to copy the pointer which was not even been allocated. Before, we were
copying the address of a NULL pointer and therefore no segmentation fault.
This commit fixes the segmentation fault by checking if the memory was allocated, i.e. should not be
in the case of CU (as it doesn't contain MAC/RLC layers).
Add CI test to force RRC IDLE and new connection setup with 5G-S-TMSI
This MR is a follow up to !2725 (merged)..
The primary goal is to introduce a CI test that enforces the following behavior:
- Forces the UE to enter RRC_IDLE state.
- Validates the UE's re-connection procedure using the 5G-S-TMSI as the UE
identity.
fix the number of preambles per SSB at UE in case PRACH is configured with groupB
To fix an issue reported in the mailing list related to UE configured by a 3rd
party gNB with groupB PRACH
* Close entity->pdusession_sock manually before pthread_join() to unblock sdap_tun_read_thread()
* Update tun_destroy() to open a fresh socket for interface management, independent from the data socket
* Fix check on success of change_interface_state() in tun_destroy(): is a boolean
* Handle ENODEV error when bringing interface down: treat as success if the interface is already gone.
* tun_destroy() is now handling INTERFACE_DOWN, so `INTERFACE_DOWN` in `tun_config()` is no longer needed
Fix PDSCH and PUSCH BWP Start and Size when PXSCH is scheduled with a DCI format x_0 in any type of PDCCH common search space
- Fix PDSCH and PUSCH BWP Start and Size when PDSCH/PUSCH is scheduled
with a DCI format x_0 in any type of PDCCH common search space
- Fix resource block assignment information (RIV field) for DCI format
x_0 when scheduling in any type of PDCCH common search space
Fix RRC resources periodicity determination according to number of slots per period
Otherwise we may end up in scenarios where some channels would end in
the wrong TDD slot type
Add enc/dec library and unit test for E1 Bearer Context Modification Failure
This MR is adding:
- the enc/dec library
- unit test
- handler and callback in stack
For the E1 Bearer Context Modification Failure.
E1 Bearer Context Release enc/dec lib and unit test
This MR is adding:
- the enc/dec library
- unit test
And adopting the lib in stack, for the E1 Bearer Context Release.
Release all SDAP entities for a UE in nr_rrc_going_to_IDLE().
With this change the SDAP entities of the UE are cleaned up
when going into RRC_IDLE, including tun sockets, threads etc.
A new SDAP entity is created when re-attaching to the network.
Move this message down, at the end of the function, if no code path
exists under which msg3 allocation might fail despite this log having
been printed.
Assume the minimum grant (min_rb) size to be the bandwidth part size. As
an example: rbStart 0, min_rb=bwpSize=106. This should pass, hence
modify these two conditions.

Signal gNB-DU config update CellStatus from DU to CU
Add the cell status to gNB-DU configuration update message, including
test. Use the gNB-DU configuration update to signal the cell status in
the stack.
This IE was not included in a previous refactoring round, but is at
least necessary to be decoded when interoperating with the OSC O-DU.
