      L1/L2 scheduling extensions for BL/CE operation, BR random-access procedure, BR PRACH detection. Still untested, but compilation succeeds. Missing elements in L2 - PUSCH programming for Msg3, Msg4 retransmission programming for BL/CE. DLSCH/ULSCH programming for UE-specific DLSCH/ULSCH for BL/CE

      bugfix: fix bug "Unknown UE_id for rnti" · 8d5901c8
      Cedric Roux authored
      This bug happens when we detect uplink failure for one UE.
      In this case, a DCI format 1A is sent to the UE to ask it
      to do random acces.
      
      The way this DCI is generated was not compatible with how
      the software is organized. It was expected that the DCI are
      added (with add_ue_spec_dci and add_common_dci) in a very
      specific order: first all DCIs in common space are added
      (with add_common_dci) then all DCIs in UE specific space
      are added (with add_ue_spec_dci).
      
      The problem was that the DCI format 1A DCI sent to the UE
      for it to do random access is added (with add_ue_spec_dci)
      before the DCIs in common space.
      
      That totally messed up the logic in add_common_dci and
      add_ue_spec_dci.
      
      The solution is to get rid of Num_common_dci and Num_ue_spec_dci,
      replace those two counters by only one (Num_dci) and add
      "search_space" in the dci_alloc structure to be used later by
      the function "allocate_CCEs" when calling "get_nCCE_offset".
      
      The software had to be adapted to the new variables, everywhere.
      
      I am not sure that the simulators work. It seems that some
      of them didn't use Num_common_dci and Num_ue_spec_dci to
      decide on what space (common or UE specific) to put the DCI,
      but relied on the rnti (comparing with SI_RNTI). To be tested
      properly.
      
      The modified simulators are:
        - openair1/SIMULATION/LTE_PHY/dlsim.c
        - openair1/SIMULATION/LTE_PHY/dlsim_tm4.c
        - openair1/SIMULATION/LTE_PHY/dlsim_tm7.c
        - openair1/SIMULATION/LTE_PHY/framegen.c
        - openair1/SIMULATION/LTE_PHY/pdcchsim.c
        - openair1/SIMULATION/LTE_PHY/syncsim.c

      RRC Rel14 · 4fcb6272
      Cedric Roux authored
      - import RRC ASN.1 defintions from the specifications
        (file openair2/RRC/LITE/MESSAGES/asn1c/ASN1_files/RRC-e10.asn)
        contrary to rel8/10, all modules have been imported, maybe it's too much
        to refine in case of problems
      - deal with rel14 in fix_asn1
      - all code that was for Rel10 is now for Rel10/Rel14
      - some incompatible changes (mostly in naming) were resolved in favor
        of rel14, see in openair2/RRC/LITE/defs.h
      - unsure about the rlc layer, some arrays have changed (values appended),
        I only changed the definition and in tests in the code, I changed
        the index limit, maybe it's not enough
      
      Rel14 is the default compilation mode.

      rewrite sort_UE for UL and DL and adapt the rest to the change · da75a078
      Cedric Roux authored
      The previous version did not seem to work properly with
      several UEs. I too often ended up with a list 'next' where
      next[i] = i, leading to an infinite loop, crashing the
      processing.
      
      The sorting functions were hard to understand and too slow
      anyway (O(n*n)).
      
      We now use qsort_r and comparison functions, that should
      define the same order as the previous version.
      
      One important point is that the "next" lists and the "head"
      variable are now considered invalid before calling sort_UE.
      
      So all the code (coming before sort_UE) that looped using those
      variables has been rewritten to loop over all possible UEs and
      the first instruction of the loop is to exit the loop if the UE
      is not 'active'. There is room for improvement here. We will
      reintroduce a list of some kind at some point. Let's first
      have something that works and then optimize. Today NUMBER_OF_UE_MAX
      is 16, that's not a big deal.
      
      Consequently, the add_new_ue and rrc_mac_remove_ue have also
      been rewritten, hopefully for the better.
      
      This commit is not a basic work and may introduce some
      problems.

      better (maybe) freeing of RA process when an UE is removed from MAC · c824eea0
      Cedric Roux authored
      The RA process may be in the state:
      RA_active == FALSE and wait_ack_Msg4 == 1
      
      Testing only the rnti should be enough, if everything else works
      properly.
      
      Also, don't break, just in case. (Not sure it makes a
      difference.)
