new interpretation of sdr_addrs string in RU config file: this is now directly passed to the uhd to specify a device. It may contain a device type (i.e., "type=x300") or an IP address (i.e., "addr=192.168.10.2")

In TDD mode the eNB does not output data all the time, only in downlink and special subframes. The basic simulator needs a continuous stream of samples. So let's fill the blank with silence.

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. Conflicts: targets/ARCH/USRP/USERSPACE/LIB/usrp_lib.cpp

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.

This commit introduces a 'basic simulator'. This basic simulator is made of: - the standard eNB code using a special driver that mimics the USRP driver - the standard UE code using a special driver that mimics the USRP driver - no channel simulation - some special code to deal with faster-than-realtime behaviour of this basic simulator It connects one UE to one eNB. It requires an EPC, populated with the correct configuration for the UE. This is the initial release and may contain bugs (most probably race conditions due to the faster-than-realtime behaviour). To use it, see the documentation at: targets/ARCH/tcp_bridge/README.tcp_bridge_oai. It has been tested with 25, 50 and 100 RBs, FDD mode. (No check at all has been done to know if it could work in TDD mode.)

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.

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.

How to use: 1 - compilation of softmodem: ./build_oai --eNB -t ETHERNET 2 - compilation of mobipass driver: cd cmake_targets/lte_build_oai/build make oai_mobipass ln -sf liboai_mobipass.so liboai_transpro.so 3 - configuration: edit the configuration file, set "node_timing" to "synch_to_mobipass_standalone" that is, have the line: node_timing = "synch_to_mobipass_standalone"; 4 - run: run as usual: sudo ./lte-softmodem -C <configuration file>
