Added NTN FDD FR1 bands defined in 3GPP TS 38.101-5
Added support for NTN FDD FR1 bands 254, 255, 256 as specified in 3GPP
TS 38.101-5. Example Conf files added for band254 for 15Khz, 5Mhz and
30Khz, 10Mhz configurations. Tested NTN GEO configuration on band 254
using these conf files.
NR UE trigger for re-establishment
The implementation in this MR triggers RRC re-establishment at the UE in case
of radio link failure either for out of sync messages from lower layers or in
case maximum number of RLC retransmissions is reached.

Set SA mode as default
- Set standalone (SA) mode as the default.
- Adjust commands in Docker Compose files by removing --sa flags and
adding --nsa flags where applicable.
- Add a function to verify that only one mode is being used at a time.
- Update all relevant documentation.
telnetsrv uses the Intel/AMD-specific "cpuid" instruction, which is not
available on ARM machines. Remove the call.
The previous code was checking for the number of cores, which is
retained by a call to get_nprocs(). I did not find an equivalent for the
number of threads in C. In C++, there would be
https://en.cppreference.com/w/cpp/thread/thread/hardware_concurrency, in
case it's relevant for anybody.
Update yaml-cpp dependency handling
- Added CPM fallback in case package is not found automatically.
- Using yaml-cpp::yaml-cpp target instead of yaml-cpp to silence
deprecation warnings on newer cmake versions.

Add F1 Handover procedures
- Clean up at RRC and MAC
- Add DU handover procedures, completely handle CellGroupConfig at DU
- Add CU handover procedures
- Maintain reestablishment working between/after handover
- Changes at UE to resync on different frequency DUs
Instructions: see doc/handover-tutorial.md
Things not implemented/open/missing: see #855
process registration reject in UE
when the 5GC rejects the ue, the message was not processed (information
element not declared)
this MR process it to print it and stop the UE
a more complete code should be done when the UE will be able to select
another cells than the most powerful PBCH, but it require larger
enhancement
- Fixes#853, #854, #858, #859, #862
- handle repeated NGAP Initial context setup requests, thereby fixing assert:
Assertion (!ue_p->as_security_active) failed!
In rrc_gNB_generate_SecurityModeCommand() /home/eurecom/raymond/openairinterface5g/openair2/RRC/NR/rrc_gNB.c:2590
logic error: security already activ
- A lot of cleanup: remove almost all use of protocol_ctxt_t in 5G RRC and use
existing pointers instead
This changes the way T_IDs are defined. The T_ID macro was using a
integer to pointer cast in order to provide type safety. This trick
disables some compiler optimizations, as explained here:
https://clang.llvm.org/extra/clang-tidy/checks/performance/no-int-to-ptr.html.
Removing the type cast reenables the compiler optimizations.

Since long long is the bigger type ( 8 bytes ) of the two used ( long long and uint32_t ),
and long long is also available on ARM, change this parameter to always have this type.
This allows to always use format specifier '%lld' in the logs that use TICK_TO_US, which would otherwise return long long or uint32_t depending on architecture.
