Andre Puschmann 44baea6666 mac_nr: add UL HARQ
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.

faluco a2f6e13138 Add a tag to the string memory pool in fmt to discriminate between pool vs heap allocated buffers. Heap allocated buffers are used as a fallback mechanism when the buffer runs out of space. 2021-04-13 17:36:39 +02:00
faluco 0465f6badd Implement a pool in FMT to avoid allocating heap memory when passing a char* to the backend, usually when formatting a %s argument.
Previously since a char* can have any length, this was managed by FMT by converting it into a std::string.
Now we store it into a configurable size node that can store a fixed size string, otherwise it falls back to std::string.

Andre Puschmann 48537f3fe7 pdcp,rlc: increase number of PDCP SDUs for notification from RLC
the current value of 256 limits the number of PDCP SDUs that can be
notified from RLC. The limit is quickly hit when too many SDUs
are in flight. This can cause unwanted log entries and weird PDCP
behaviour.

the patch increases the value to 1024, which still can be too few if
many smaller SDUs are traveling.

The patch also set the log level to warning to quicker spot
misconfigs in logs.

Fixes #2616

Andre Puschmann 9950278a12 nr,mac_sch_pdu,mux: fix packing of MAC subPDUs with 16bit L field
the created RLC PDU was too large to fit inside the MAC grant
because only the header room for the short L field was used.

The patch determines the correct size before passing the opportunity to RLC.

It also improves logging in error case by using the MAC logger instead of
stderr/stdout when error occurs.

Andre Puschmann db496df1e6 mac_nr: add support for periodic BSR reporting
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)

Francisco dc763b5045 rlc am - fix bugs in buffered_pdcp_pdu_list
The count and container elements were not being correctly updated in the events
of SN overwrite, clear(), clear_pdcp_sdu(sn) of sn that doesnt exist

Francisco ebbb74e639 rlc am - use of circular_map container in RLC AM window
The window elements are not being correctly cleaned up when clear() is called
or when overwritten by newer SN. Furthermore, the window count member is not being
correctly updated when the insertion of a newer SN overwrites the previous one.

I used the circular_map container to avoid this sort of bugs
