      bugfix: fix threading in the UE · a48c3658
      Cedric Roux authored
      Various problems were found with the basic simulator.
      
      Variables used by various threads for synchronization need to
      be initialized properly. That is before the various threads
      start using them.
      
      This goes for:
      - UE->is_synchronized
      - UE->proc.instance_cnt_synch
      - UE->proc.instance_cnt_rxtx
      
      The function "UE->rfdevice.trx_start_func" was called in
      "UE_thread_synch" but should be called in "UE_thread" because
      "UE_thread" is the one that calls "UE->rfdevice.trx_read_func"
      and there is no guaranty that the call to "UE->rfdevice.trx_start_func"
      is done before as it has to (it's in another thread).
      
      And finally "pthread_cond_signal(&proc->cond_rxtx)" was called twice,
      which may not be a problem but was certainly not intended. Plus
      removing one call simplifies the code by removing some "if" logic,
      which is a good thing per se.
      
      This commit was not tested with a real UE and may thus introduce some
      issues. Hopefully not!

      basic simulator: bugfix: wait for synch ready at the right time · 97ddf5ea
      Cedric Roux authored
      Before this commit we were checking for UE->is_synchronized == 0
      then we were waiting for a potentially active synch routine to
      finish and then we were starting the synch routine again but the
      synch routine that was running may have set UE->is_synchronized
      to 1. This was leading to various problems, most notably the following
      message repeated over and over in the UE log and the UE unable to
      connect properly:
      
          [RRC]  [UE 0] Frame 377: OUT OF SYNC FROM eNB 0 (T310 active 0 : T310 0, N310 345, N311 0)
      
      So let's wait for a potentially active synch routine to finish
      before anything else.

      minor fixes for x2 + modify conf files · 3b3b9718
      Konstantinos Alexandris authored
      The configuration file has now to contain ENB_IPV4_ADDRESS_FOR_X2C and
      ENB_PORT_FOR_X2C in the NETWORK_INTERFACES section.
      
      For example:
      
          NETWORK_INTERFACES :
          {
              ENB_INTERFACE_NAME_FOR_S1_MME            = "eth0";
              ENB_IPV4_ADDRESS_FOR_S1_MME              = "192.168.12.111/24";
              ENB_INTERFACE_NAME_FOR_S1U               = "eth0";
              ENB_IPV4_ADDRESS_FOR_S1U                 = "192.168.12.111/24";
              ENB_PORT_FOR_S1U                         = 2152; # Spec 2152
      
              ENB_IPV4_ADDRESS_FOR_X2C                 = "192.168.12.111/24";
              ENB_PORT_FOR_X2C                         = 36422; # Spec 36422
          };

      USRP addressess and clock sources can be configured in the configuration file... · be0e4095
      Eino Virtanen authored
      USRP addressess and clock sources can be configured in the configuration file with the RU section with comma separated IP addresses in 'sdr_addrs' and with strings "internal"/"external"/"gpsdo" in 'clock_src'.
      
      TODO: Currently the driver picks the two first RX and TX channels when nb_tx and nb_rx are both set to 2. If a developers wants to force usage of two devices, 'set_rx_subdev_spec' and 'set_tx_subdev_spec' can be used to indicate to the driver so that antennas from separate devices will be used. To rephrase: until 4 antennas are supported by OAI, testing with two devices, so that antennas from both devices are used, requires manual configuration of which subdevices' antennas are used.

      basic simulator is now functional · 072cf567
      Cedric Roux authored
      The power estimation of the UE has to be debugged (calibrated?).
      In the meantime, using "--ue-rxgain 140" lets the UE and eNB
      talk to each other in the basic simulator.
