MR968: Bugfix nr ldpc size typo
- fix the copy of the decoded data bytes at the end of the processing of an LDPC segment
MR962: Remove x2 gnb hardcoding
- Removes hardcoding of some x2 configuration parameters used in ENDC setup request message at gNB side
MR949: rlc v2: change time keeping
- RLC has timers. We need to keep track of time.
We introduce rlc_tick() and call it in eNB_dlsch_ulsch_scheduler, which is called every subframe, both in FDD and TDD.
MR945 : nr prach fr2
- Introduction of the PRACH frontend for FR2 (120kHz SCS, 32 and 66 PRB).
- Tested with nr_prachsim and testcases added to test_case_list.xml also included some fixes for FR1,
when prach occasion > 0 (small difference in Ncp)
MR950 : DL and UL PTRS for 5G NR
MR971 : Correct NDI + Minor MAC subPDU handling improvements
Fixes the issue : Ping in develop was unusually high (70+ms). The issue was that TA was scheduled in the second slot (of the two we currently schedule), but NDI was toggled for the first one.
Other improvements:
- Correctly put padding MAC subPDU
- Only use subPDU DLSCH long header if length >= 256B
- Calculate TBS in DL pre-processor considering header and TA CE overhead.
- Improve some of the logging (LOG_D)
- re-enable TA
MR970 : uci gnb mac functions file
- Moved gNB MAC UCI related functions in a new file
MR972 : Bugfix nr rate matching assertion
- Fixes the assertion happening in rate matching of pdsch during iperf test.
MR975 : File openning in rrc_gNB_internal
- Only allow file opening in rrc_gNB-internal.c in phytest mode
MR977 : NR UE DCI sanity checks and fixes
These changes resolve a few stability issues and errors in NR UE
- Added sanity check for pucch_resource_indicator received in DL DCI, which resolves SEGV in select_pucch_resource() and check_pucch_format()
- Additional sanity checks included to catch false or erroneous DCI received
- Wrong MCS table calculation and error in accessing ul_config_request at UE resolved
RLC has timers. We need to keep track of time. We chose to not use
realtime but 'processing time'. That is we send a tick to RLC for every
subframe when it is processed by the softmodem. Before this commit we
used to increase time in the function mac_rlc_status_ind which may not be
called every subframe (especially in TDD mode). So we need another way
to keep track of time.
We introduce rlc_tick() and call it in eNB_dlsch_ulsch_scheduler, which
is called every subframe, both in FDD and TDD.
We also call rlc_tick() in the function ru_thread_synch() because
pdcp_run() and rrc_rx_tx() are called there too.
It may not be the best solution. To be revised if needed.
Note: the UE has not been touched. Some modification is needed for the UE
too, most probably.
MR932 : Nr sa ngap rrc wk42
- Initial implementation of NGAP and RRC extensions for SA
MR956 : Correct use of ssb_position bitmaps
MR958 : 5G NR Downlink DMRS Type 2
- Implementation of 5G NR Downlink DMRS type 2 (generation on gNB side, channel estimation with linear interpolation in frequency domain on UE side), needed for MIMO
MR961 : 5G NR UE TTI cleanup
- Remove current_thread_id array, nr_tti_rx, nr_tti_tx, subframe_rx and subframe_tx
MR965 : fix a segdev
