      MR !1054 : gNB_multi-threading_rework
      -Replacing the existing multi-threading pipeline with threadPool library, simpler and more robust
      -Updated dlsim to print stats to matlab file.
      -Small fix for UE Ulsch coding.
      
      
      MR !1063 : T_tracer__add_gnb_tracer
      Minimalist gnb tracer to trace (for the moment) rxdataF when some decoding for PUCCH or PUSCH has been done
      
      MR !1070 : nr_pdcp_improvements
      Implement data transfer (38.331 5.2): - transmit operation (in nr_pdcp_entity_recv_sdu) - receive operation (in nr_pdcp_entity_recv_pdu) - t-Reordering expiration
      
      MR !1076 : PBCHNRTCFIX
      Issue Details: If bchPayload is changed to non-zero value, then the test case used to fail.
      Solution: While final check against UE decoded bchpayload and input bchpayload, the AND operation with 0xff is missing along with RIGHT SHIFT operation for input bchpayload.
      
      
      MR !973 : s1_subnormal
      LTE update in S1 functions from Fujitsu.
      -NNSF
      -S1AP auto recovery.
      -Handling unexpected messages.
      -Fix memory leak.
      
      
      MR !1048 : develop_SA_RA
      -Draft and initial trigger of RA procedures upon SIB1 reception. 
      -Improvements on SA SIB1 reception.
      -Get Msg3 from RRC to MAC layer (this fixes random Msg3). 
      -Fix Tables 7.4.1.1.2-1/2 from 38.211.

      - 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

      NR_UE: handle initial TA the same way as TA updates, independent of the UE_mode · 01645168
      Thomas Schlichter authored
      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.

      nr pdcp: improvements · 9edc8cce
      Cedric Roux authored
      Implement data transfer (38.331 5.2):
          - transmit operation (in nr_pdcp_entity_recv_sdu)
          - receive operation (in nr_pdcp_entity_recv_pdu)
          - t-Reordering expiration
      
      To keep track of time the function nr_pdcp_wakeup_timer_thread has been
      added and is called by the gNB's MAC scheduler via nr_pdcp_tick.
      
      (The UE has not been modified.)
      
      A thread has been introduced to set time of all the existing PDCP
      entities in the system. This probably does not scale well with many
      PDCP entities (many UEs connected to the gNB). To be changed at some
      point when needed. Hopefully, with a few UEs this mechanism won't be
      too problematic (ie. won't cause realtime problems).
      
      The problem with time in PDCP is that SDUs are kept if some are
      missing, to do reordering. A timer is started and when it expires
      we have to transmit the SDUs even if some are still missing. We
      want to do that as soon as possible. So we have to check timers
      often (every millisecond).
      
      In RLC the time is set when there is so...

      T tracer: add gnb tracer · 95b659ab
      Cedric Roux authored
      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
