the EPS bearer manager was only informed when a single DRB
was removed but not when entering idle which requires to
remove all bearers.
This cause the service request to fail.
this is a rather large commit that is hard to split because
it touches quite a few components.
It's a preparation patch for adding NR split bearers in the next
step.
We realized that managing RLC and PDCP bearers for both NR and LTE
in the same entity doesn't work. This is because we use the LCID
as a key for all accesses. With NR dual connectivity however we
can have the same LCID active at the same time for both LTE and NR
carriers.
The patch solves that by creating a dedicated NR instance for RLC/PDCP
in the stack. But then the question arises for UL traffic on, e.g. LCID 4
what PDCP instance the GW should use for pushing SDUs. It doesnt' know
that. And in fact it doesn't need to. It just needs to know EPS
bearer IDs. So the next change was to remove the knowledge of what
LCIDs are from the GW. Make is agnostic and only work on EPS bearer IDs.
The handling and mapping between EPS bearer IDs and LCIDs for LTE
or NR (mainly PDCP for pushing data) is done in the Stack because
it has access to both.
The NAS also has a EPS bearer map but only knows about default and
dedicated bearers. It doesn't know on which logical channels they
are transmitted.
the issue let to unwanted log warning at the end of the UE
execution when the PHY was still pushing DL PDUs while MAC
was already stopped.
This fixes#3003
general-purpose method for lower layers to signal protocol
failures to higher layers, i.e. RRC.
In the current case, implement a direct release of the UE (enb) or
a reestablishment (UE).
races detected with TSAN, primarily the ue_sync object which isn't
thread-safe is accessed by all workers to set the CFO and by the
sync thread to receive samples (which read the CFO).
The patch introduces shadow variables that are updates from the
main thread before/after the sync is executed. The atomic shadow
variables can then be read from otherthreads without holding a
mutex, i.e. blocking the sync.
in the mac_test the tb_decoded() method was called twice for
the 2nd codeword, causig TSAN to complain about an unlocked mutex
being unlocked.
The patch resolves the potential issue only calling tb_decoded
for a grant/tb thas has a non-zero MCS.
The patch also adjusts the reset function to have a safe and "unsafe"
version to be called from inside the class, similar to other
classes where we do the same.
this is an attempt to fix#2850 by defering the transmission of
the connection setup complete until the PHY has applied
the dedicated config in the connection setup.
the low timout of 10ms was:
1) causing too frequent measurement reports
2) causes a MO ping test to fail where the ICMP request
was sent on the LTE carrier but never got a reply because
the MCG addition was inbetween
this commit adds a complete DL HARQ entity to the MAC of the UE.
It also refactors demux into an own class and adapts the PHY-MAC
interface to use the new MAC capabilities.
this patch adds a basic UL HARQ entity for NR.
The patch also updates some interfaces between MAC/RA/HARQ,
i.e. get_temp_crnti().
It also adds a Msg3 unit test.
building on the previous refactor this patch now adds support
for peridoic BSR reporting (using short BSR). It furthermore does
the following changes:
* add BSR packing
* add proc_bsr_nr unit test
* move mac_nr test code into test folder under src (needs to be done with other test code too)
* refactor some common methods to mac_common.cc
* add common mux_base class
* move UL PDU generation to mux class
* add logical channel registration to MAC, MUX, BSR
* add initial proc BSR
* add basic MAC NR test
* rework MAC interfaces
inspired by accepted (but not yet merged) PR to include the
(unique_)byte_buffer_t for MAC/PHY interfacing, this patch adds
a few more useful bits to that. Buffer management for UL data is now
done in MAC and only a pointer to the data is passed in the UL action.
* Move Tx softbuffer to MAC (until UL HARQ class is ready)
* Remove temparal data member in cc_worker
* Remove memcpy after packing MAC PDU
after adding the thread-safe PCAP writer functionality to the EUTRA
MAC object it became clear that we don't wont to replicate the
same for the NR object.
This patch therefore refactors the class that now supports both EUTRA and
NR rats. The old mac_nr_pcap.[h/cc] has been deleted. All test-cases
and usages now use the new object that needs to pass the RAT type in
the ctor.
this patch addresses the last open point of #2160
* Replaced UE logger in the ue class.
* Replaced loggers in the main phy class and prach.
* Replaced loggers in phy common and ta_control.
* Replace loggers in cc and sf workers.
* Replaced loggers in intra_measure, scell_recv, search, sfn_sync, sync.
* Remove last uses of the old loggers in the main phy class.
* Remove stray newline in logs.
* Replaced loggers in ue gw.
* - Started to replace loggers in the ue stack.
- Replaced loggers in usim and pcsc.
- Adapted nas and usim tests.
* Replace loggers in nas.
* Added missing log init calls in two previously modified tests.
* Replaced logger in nas idle procs.
* Replaced loggers in nas emm state.
* Replaced loggers in tft packet filter and adapted tft test.
* Replaced loggers in main RRC class.
* Replaced loggers in RRC cell.
* Replaced loggers in RRC meas.
* Replaced loggers in rrc procedures.
* Started logger replacement in MAC layer, more precisely in demux and dl_harq classes.
Been unable to inject loggers in construction for dl_tb_process due to very weird static assertions in the std::vector code being the type not constructible which is not true, so instead use the main MAC logger directly.
* Replaced loggers in mac mux class.
* Replaced loggers in mac pro_bsr.
* Replaced loggers in mac proc phr.
* Replaced loggers in mac proc SR and RA.
* Replace loggers in mac UL HARQ.
* Replaced loggers in main ue stack class.
* Fixed nas test crashing due to a null string.
* Ported mac_test to use the new loggers.
* Removed TTI reporting for the PHY log as the old logger did.
* Replaced loggers in UE phy tests.
* Configure loggers in nas_test.
* Replaced loggers in rrc_meas_test.
* Replaced loggers in rrc_reconfig_test.
* Added missing newline in tft_test.
* Fix compilation errors in TTCN3 tests.
* Fix linker error detected in CI and warning.
* Replaced loggers in TTCN3 tests.
* Fix a text replace error in some log messages.
* Remove trailing newlines from log entries.
* Remove old logger from rrc.
* Flush backend before printing the test status.
* - Fix compilation error from previous rebase.
- Remove trailing newlines from some missing log entries.
that patch addreses issue #2199 by defering RA-related calls that
are executed from within PHY workers.
The time-critical bits of more complex functions such as tb_decoded()
are still executed in the PHY worker thread but the state machine
manipulation is defered.
* Refactor NR resource allocation classes. Use DCI instead of grant for dummy PDSCH UE/eNB test
* Minor refactors in NR workers and ue_dl
* Fix include issues
* fix compilation issues
