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>

Several problems are present. The first is that _write returns 0 instead of the number of samples. We solve it by returning nsamps. The second is that _read may return less samples at the beginning and we don't want to exit for that. We solve it also by returning nsamps. (We still need to log more in this, to be done in the next commit.) The third is that after initialization we don't send anything for a while, time for the softmodem to finish its init. This generates lots of "RX overrun". We solve it by disabling TX and RX modules after init and then in trx_brf_start we activate them again (and also call bladerf_sync_config, which seems to be mandatory, and bladerf_calibrate_dc, which may be avoided, perhaps). Maybe not the end of the story. Sometimes it works, UE connects, traffic is fine (tested only with 5MHz). Sometimes it does not, UE does not connect, or it connects but then traffic is bad, especially uplink. To be refined.

No need for this special case. Plus, it fails with the work from Nokia on compilation cleanup.
