      improve multi-UEs scenario · 622b919b
      Cedric Roux authored
      This commits contains several fixes to improve a multi-UE scenario.
      
      This is not the end of the story.
      
      Summary of work:
      ================
      
      1 - improve SR (scheduling requests):
      
          We configured n1pucch == 3 for scheduling requests, for all
          UEs. We now use 71 - UE_id/10.
      
          For it to work, it is vital that pucch_nRB_CQI in the configuration
          file is set to 0, otherwise the SR will go to an RB used for
          PUSCH and uplink decoding will fail whenever an UE does SR.
      
          Note that we will have problems with 20MHz when we use a CCE that
          let the UE send the ACK/NACK using a n1pucch allocated for SR,
          because when the PDCCH is of size 3, we can have 87 CCEs
          and it may lead to an n1pucch colliding with one for SR.
      
          The work done in this patch is a quick solution, seems to work
          with 10MHz.
      
          The real solution is to disable the use of those CCEs that would
          lead an UE to use a n1pucch colliding with an SR n1pucch. Then
          we can use whatever n1pucch w...

      hotfix: protobuf-c compilation failure · 45212d3b
      Cedric Roux authored
      protobuf-c does not compile anymore.
      
      Let's handle this a bit better.
      
      We now install protobuf and protobuf-c only for the
      flexran agent. That is, if you want to use the flexran
      agent, you need to install protobuf/protobuf-c and
      you do it this way:
      
        ./build_oai -I -a
      
      (you add -a)
      
      Other targets don't need protobuf nor protobuf-c, so
      it's not installed by the -I command of build_oai,
      unless you pass -a with -I.
      
      Also, we now use protobuf 3.3.0, not 2.6.1. The code
      has been adapted, a quick test seems to indicate that
      the system works, but it has not been intensively tested.

      fix vcd · 309ca066
      Cedric Roux authored
      several problems were present:
      - there was no comma after "ue0_trx_write_ns_missing" in the array
        eurecomVariablesNames;
        comma was put, and also commas for the last element in the array,
        which doesn't hurt and will prevent future problems
      - bad order of values in eurecomVariablesNames, which
        was different from the enum vcd_signal_dump_variables;
        order was checked and fixed
      - strange/wrong use of VCD_SIGNAL_DUMPER_MODULE_END/LAST;
        the whole logic was removed/simplified

      Merge branch 'develop_integration_w30' into 'develop' · f7466b0e
      Cedric Roux authored
      Summary of changes:
      - UE: new thread idx
      - UE: Pdcch optim
      - UE: slot0 slot1 parallelization
      - bugfixes for RLC AM (see gitlab issue 250)
      - fix bug "unknown UE_id for rnti"
      
      Note: due to the new UE threading architecture,
      oaisim and the phy simulators may not work properly
      anymore. Adaptation in the code has been done, automatic
      tests seem to pass, but it may not be enough.

      bugfix for phy simulators (not sure if enough) · 9e4f700a
      Cedric Roux authored
      With the new threading architecture of the UE dlsim
      (and others) does not work properly anymore.
      
      When looking at the scope, you see a difference
      in PDSCH LLR display. The end is always 0 where
      in the current develop branch (tag 2017.w25) it's not.
      
      This commit attempts to fix it.
      
      We still don't have the same behavior as in 2017.w25.
      I disabled channel simulation (so that UE RX = eNB TX)
      and I have one error where in 2017.w25 I have zero.
      For example, here comes the output of a run of "./dlsim":
      
      **********************SNR = 0.000000 dB (tx_lev 51.000000)**************************
      Errors (1(0)/1000 0/1 0/0 0/0), Pe = (1.000000e-03,0.000000e+00,-nan,-nan), dci_errors 0/1001, Pe = 0.000000e+00 => effective rate 99.900100, normalized delay 0.001472 (1.001000)
      
      And in 2017.w25 we have (with the same hack to disable
      channel simulation):
      
      **********************SNR = 0.000000 dB (tx_lev 51.000000)**************************
      Errors (0(0)/1000 0/0 0/0 0/0), Pe = (0.000000e+00,-nan,-nan,-nan), dci_errors 0/1000, Pe = 0.000000e+00 => effective rate 100.000000, normalized delay 0.001471 (1.000000)
      
      There may be a problem somewhere. Or there was one before and we should
      have had one error and the new UE architecture fixed things and now
      it's as it has to be. Hard to say at this point...
      
      When looking at the scope we quickly see some zeros for the PDSCH
      LLR, at the begining this time, not at the end. This is just when
      the GUI appears and then all is fine, so this seems to be for the
      first frame only. In 2017.w25 this does not happen.
