There was a problem with several UEs in the wireshark log. It seems that
wireshark needs the UE id otherwise it gets confused and sees retransmissions
where it's just another UE connecting and doing the same as a previous
UE.
Let's put kind of a UE id. Each RNTI seen by macpdu2wireshark gets an UE id
assigned the first time it's seen in a trace.
This is a bit hackish but seems to be fine.
We could have added UE_id in all the traces, that is change the T() calls
in the softmodem. It was less work to do it as it is, ie. only touch
macpdu2wireshark.c.
The RAR uses the same UE id all the time, may be a problem. To be refined
if needed.
If we NACK without SOstart/SOend then the other end of the RLC channel will consider all the bytes as NACKed and will have to resend them all.
If another status is then reported before all the bytes are sent, and because we don't use SOstart/SOend this status will NACK all the bytes again, then all the bytes are to be sent again.
And the cycle repeats. It will end with a max retx reached (which triggers RLF, Radio Link Failure).
MR1010 : NR UE: Fix for error message - no active DLSCH
- Fixes for the following error message at UE: [PHY] [UE][FATAL] nr_slot_rx 1: no active DLSCH
MR994 : Cleanup softmodem main
- Introduces --dlsch-parallel command line option to set the number of threads for dlsch decoding. If set to 0 (default) no parallelization.
- Some cleanup in tracing and in nr-uesoftmodem.c data.
MR999 : NR FR2 RA
- Temporary Fix of RA procedure for FR2 (both gNB and UE)
- Fixes in gold sequence initialization at UE
- Moves 2nd downlink to slot 3 instead of 2 to avoid clash with UL DCI (only 1 candidate per slot in FR2 currently)
MR988 : SIB1
Initial implementation of SIB1
- CDM groups used, multiple DMRS locations tested
- REMOVED compiler define NR_SC_FDMA
- enabled -Z option in ulsim for testing NR SC-FDMA
- Gnb UL Processing of LLRS even if last symbol allocated has no data
- transform precoding Enumerations used
MR991: Remove hack in LTE PDCP for noS1 mode
- Removes a hack which was used when LTE PDCP was used for NR in noS1 mode
MR993: UL and DL fixes LDPC short codewords
- Fix UL & DL LDPC decoding for short LDPC code, e.g. Z_c is not multiple of 8
- Fix DLSCH data transmission with multiple DMRS symbols per slot
- small TA fixes on OAI 5G NR UE
- Implemented CQI measurement at NR UE
- NR UE cleanup
