      Compare version number using MAKE_VERSION macro to provide better SW configuration: · 5c23af77
      Bi-Ruei, Chiu authored
      1. Previous SW configuration for different RRC version relies on whether macro Rel10,
         Rel14 defined or not by checking #ifdef Rel14 or #if defined(Rel10) || defined(R14).
         Whenever there is a newer RRC version, e.g. Rel15, it will be very a tedious and
         error-prone job to add defined(Rel15) in every place.
      
      2. Some RRC messages are defined in release 13 instead of release 14, NB-IoT
         feature is one of such example. Our code shall reflect this fact instead of using
         an afterward version number in software configuration.
      
      3. Some RRC messages or some fields of certain RRC messages are added in the middle
         a release, e.g. SystemInformationBlockType1_v1310_IEs_t defined in RRC 13.1.0
         and RRC 9.2.0 made some changes to SIB12 and SIB13 so we have sib12_v920 and
         sib13_v920 fields in SIB12 and SIB13's struct.
         We need a finer grain of control when using ASN1 from different RRC version.
      
      4. S1AP also has this problem that it use UPDATE_RELEASE_9 and UPDATE_RELEASE_10 to
         differentiate between various S1AP version.
      
      This commit propose using MAKE_VERSION(x,y,z) to designate the version number and
      modify current conditional compilation accordingly.
      
      Note: 2018/04/16, Modified based on Cedric's comment.

      bugfix: don't take into account report CQI in case of NACK or DTX · c0bcd786
      Cedric Roux authored
      The problem that may happen is that when the UE does not transmit
      on PUCCH (for whatever reason) we may get no signal at all, and
      thus compute a very low CQI. Later on we may ask the UE to transmit
      louder which may lead to saturation and more problems.
      
      The solution is simple: don't care about CQI in case of DTX
      (and NACK also, as done for PUSCH).
      
      Only FDD case done.
      For TDD it seems that:
      - nfapi structures are not correct. See nfapi_harq_indication_tdd_rel13_t
        in nfapi/open-nFAPI/nfapi/public_inc/nfapi_interface.h, all the cases
        (bundling, multiplex, ...) use nfapi_harq_indication_tdd_harq_data_t
      - the function extract_harq does not handle TDD

      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.

      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.

      - change target values
      - change upper/lower limit to trigger a tpc
      - don't use ul_cqi from SR
      
      The value of ul_cqi is not convincing, for both PUSCH and PUCCH,
      more work/analysis is required.

      bugfix: fix timing advance · 9b428e5e
      Cedric Roux authored
      - re-use ta_timer
      - when ta_timer is running:
        - no TA sent to UE
        - no TA from UE (for UE to have time to apply previous TA command)
      - decrease ta_timer every TTI
      - be careful to use correct value of ta_update (31 means no TA)
      
      Maybe not correct, to be checked.

      - don't use o_flip anymore in ulsch_decoding
      - remove dl_cqi from eNB_UE_STATS

      - 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...
