- FAPI structures not to be used as config_req at MAC since that FAPI is
just for communication between MAC and PHY
- additional frame_type member added to the FAPI struct
- removed commented out code
- improved logging in UL channel estimation
- minor fixes according to OAI coding guidelines
- moving fetching TDD configuration parameters in nr-ue.c only in TDD case
In FDD mode, the UE_mode switches to PUSCH mode before the initial TA value was applied.
Because of this, the ta_command was misinterpreted.
Fix this by adding 31 to the initial TA comamnd and handle it the same as TA updates.
Minimalist gnb tracer to trace (for the moment) rxdataF when some
decoding for PUCCH or PUSCH has been done.
Important: T_BUFFER_MAX and T_CACHE_SIZE have been changed. T_BUFFER_MAX
is twice as big as before. T_CACHE_SIZE has been devided by two. Globally,
the memory usage of the T tracer is the same, but since we divided by two
the number of buffers in the cache, we may hit some realtime problems if
all the buffers are busy at some point. The simple solution would be to
use 8192*2 for T_CACHE_SIZE as it was, but then we double the memory usage
of the T tracer. This, or another solution, to be defined.
MR1029 : Benetel driver update
This MR fixes an issue with the driver for the 4G Benetel RRUs.
Power levels on the 5G side were adapted to avoid saturation of the signals.
5G performance is now the same as with USRP.
Support for 2 antennas for both 4G and 5G was added
MR1062 : fixing the RE offset for each Rx antenna in pusch channel estimation
MR1046 : Add support for NR UL SC-FDMA up to 100 MHz
MR1053Nr : pdcp nea2 security
MR1049 : improve rfsim
-Fix a regression
Earlier parameter reading was moved to an external thread,
Eventually the check at the end of the main was too early,
Declaration of some extra parameters are now on command line
-Enhancement:
use the rfsim as a server on UE side, so we can connect two xNB to one UE
-Simplification:
remove rfsim flags that have been made for convergence with replay function in usrp driver, but this is useless as they changed their code
-Fix a bug in ubuntu 20.04 (now the code is ready in whole OAI)
MR1056 : Bugfix: NR BSR calculation
Fixes a bug in the scheduler for BSR calculation.
Before, we might wrongly track the BSR of a UE and not schedule it anymore although it has data.
Should be fixed now and improve UL throughput.
MR963 : Nr mac multi rach global edge
-Handling of Multiple Users triggering RACH request in different RACH Occasions in same slot
-Providing Random Access Response according to RACH request
MR978 :
We have incorporated 5G NR nFAPI into the develop branch
P5 and P7 interfaces for NR have been implemented.
With this MR, downlink transmission through nFAPI will be possible.
We have also made sure that 4G nFAPI can be used from within the develop branch.
