      MR957 : rlc v2: implement SOstart/SOend in NACK reporting · 951fdfef
      Remi Hardy authored
      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

      MR960: 256 QAM demodulation routines  
      - Added functions for demodulation of 256 QAM signals.
      - Added a command line flag to enable mcs table entry in PDSCH-Config in RRC to use 2nd MCS table for PDSCH.
      - Added an option for using 256 QAM mcs table in nr_dlsim.
      MR989: Docker and Deployment improvements (CI)  
      - Image generation for eNB --> template for configuration files and dedicated entrypoint in Ubuntu
      - Docker-compose-based EPC deploy
      - Traffic test fully validated using the `trf-gen` container
      - Flexran-rtc support when deployed in a container (Not fully done for the X2 Handover part)
      - Added docker-compose-based eNB deployment
      - Retrieve logs for such eNB deploymnent 
      - Functional and log  update of nsa fr1 test but valid for gNB terminate also (enhanced ping stats and gNB markers)
      MR992: Fix data transmission in "do-ra" mode
      - UL and DL Traffic works now in do-ra mode, but there are still some PUCCH issues remaining. These issues are harming the acknowledgement of DL packets, and thus leading to unnecessary retransmissions.
      The relevant warnings at UE are:
      `PUCCH Invalid pucch resource indicator: at line 1082 in function select_pucch_resource of file openair1/SCHED_NR_UE/pucch_uci_ue_nr.c`
      `PUCCH Error for number of bits for acknowledgment : at line 909 in function get_downlink_ack of file openair1/SCHED_NR_UE/pucch_uci_ue_nr.c`
      Note: UE needs rbconfig.raw and reconfig.raw files from the *currently* running gNB, as the C-RNTI is random and different for each run.
