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

Libraries
General
- The T tracer: a generic tracing tool (VCD, Wireshark, GUI, to save for later, ...)
- OPT: how to trace to wireshark
- The configuration module
- The logging module
- The shared object loader
- The threadpool used in L1
- The LDPC implementation is a shared library
Radios
Some directories under radio contain READMEs:
The other SDRs (AW2S, LimeSDR, ...) have no READMEs.
Special-purpose libraries
- OAI has two scopes: one based on Xforms and one based on imgui, described in this README
- OAI comes with an integrated telnet server to monitor and control
- OAI comes with an integrated web server
Testing
- UnitTests.md explains the unit testing setup
- TESTBenches.md lists the CI setup and links to pipelines
Developer tools
- formatting is a clang-format error detection tool
- iwyu is a tool to detect
