      Fix NFAPI integration · 922b5b59
      Cedric Roux authored
      This commit fixes issues introduced by the previous commit.
      
      Summary of work:
      - cleanup:
        - fix LOG_XX to be less verbose
        - fix cmake_targets/CMakeLists.txt
        - fix oaienv
        - remove dead code
      - bug fixes:
        - in openair1/SCHED/fapi_l1.c we had:
            eNB->pdcch_vars[subframe&1].num_dci           = number_dci;
          should be:
            eNB->pdcch_vars[subframe&1].num_dci           = 0;
          This bug let the PHY send more DCIs than what should have been
          sent because num_dci is incremented later on in the code.
          This fix may be a problem for fapi mode, to be checked.
        - add new T VCD traces
        - revert openair1/PHY/TOOLS/file_output.c to 'develop' version
        - remove thread_id in logRecord/logRecord_mt
        - revert (and adapt) configuration files
        - be careful when doing frame++, we need to % 1024
        - revert target_rx_power in openair2/LAYER2/MAC/eNB_scheduler_ulsch.c
      - NFAPI:
        - the open-nFAPI code has been included in the repository. See nfapi/README.
          Maybe we should "git clone" the Cisco repository instead. We have to be
          careful of availability though.
      
      What has been tested:
      - monolithic eNB FDD 5/10MHz with one UE, iperf UDP/TCP uplink/downlink
      
      Anything else may fail to work, especially the FAPI mode, which has not
      been tested at all.

      import NFAPI work from David Price from Cisco (non-working commit, do not use it) · 7757b9e7
      Cedric Roux authored
      It has been chosen to not include the full history of commits
      from David. He included a binary version of wireshark, probably
      a modified one that understands NFAPI. Wireshark is released under
      the GPL license, we cannot include it in the repository. We could
      have done a next commit to remove this binary. But then it would
      still be present in the history of commits, which may not be allowed.
      And it would take space on disk. We could edit the history to remove
      wireshark entirely. But this operation is too complicated.
      
      There was also a pcap capture file, which has nothing to do in
      the history of commits and would take space on disk. There again,
      it's too difficult to edit the history to remove it.
      
      There was a file .gitignore that was also removed.
      
      The original history can be found on David's repository:
      https://gitlab.eurecom.fr/daveprice/openairinterface5g/
      The branch is: nfapi-ru-rau-split.
      
      A copy of that branch has been included in the internal OAI
      repository, for those who have access to it.
      The branch is the same. The last commit ID is
      9106438239e0bc626ff1fa1d97d911caadd0fbb9.
      
      You can compare the current commit with the commit 9106...
      to see what differs.
      
      The current commit has to be considered non-working.
      The commit following the current commit will fix problems with
      the work in the current commit.
      
      If you use git bisect, don't spend time analyzing the current
      commit.

      bugfix: fix timing advance · 6da42658
      Cedric Roux authored
      - remove global variables in the function lte_est_timing_advance_pusch
      - do the smoothing logic that was in lte_est_timing_advance_pusch
        in rx_sdu (is it necessary? is it correct?)
      - put back the value 100 in prach_procedures for the test on prach energy
      - change the value of timing_advance_update
      
        it was:
      
           timing_advance_update                  = sync_pos - eNB->frame_parms.nb_prefix_samples/4; //to check
      
        it is now:
      
           timing_advance_update                  = sync_pos; // - eNB->frame_parms.nb_prefix_samples/4; //to check
      
        this should be checked somehow. The computation looked suspicious. Maybe
        the new one is wrong.

      remove gcc warnings · f1e8bff3
      Cedric Roux authored
      phy_init_lte_ue_signal was renamed init_lte_ue_signal in openair1/PHY/INIT/defs.h
      maybe it's the opposite that should have been done?
      
      Functions used in one file and defined in another may have been
      declared in the wrong header file.

      improve crnti reception (still not correct, we need to reconfigure the UE) · 256c5ab0
      Cedric Roux authored
      TODO: if the UE did random access (followed by a MAC uplink with
      CRNTI) because none of its scheduling request was granted, then
      according to 36.321 5.4.4 the UE's MAC will notify RRC to release
      PUCCH/SRS. According to 36.331 5.3.13 the UE will then apply
      default configuration for CQI reporting and scheduling requests,
      which basically means that the CQI requests won't work anymore and
      that the UE won't do any scheduling request anymore as long as the
      eNB doesn't reconfigure the UE.
      We have to take care of this. As the code is, nothing is done and
      the UE state in the eNB is wrong.

      bugfix: fix CQI reporting · c97e0546
      Cedric Roux authored
      - don't use o_flip anymore in ulsch_decoding
      - remove dl_cqi from eNB_UE_STATS
      - put dl_cqi[NFAPI_CC_MAX] in UE_sched_ctrl
      - adapt code for this dl_cqi change (from eNB_UE_STATS to UE_sched_ctrl)
      - extract_pusch_csi has been fixed for CQI_ReportModeAperiodic_rm30,
        the others need to be done. Program will exit if one uses them.
        Not sure if setting sched_ctl->dl_cqi[CC_idP]  has to be done in this
        function...
