Summary of changes: - Implementation of paging (see issue #255 in gitlab) - Implementation of RRC RE-ESTABLISHMENT (see issue #256 in gitlab) - Implementation of RRC CONNECTION RELEASE (see issue #257 in gitlab) Some modifications with timers have been done. Expect (and report) problems, thanks. What has been tested: - monolithic eNB 5 and 10MHz with one commercial UE. UDP and TCP traffic, uplink and downlink, with iperf (with a third party EPC, not openair-cn). TCP downlink traffic is not stable. Reason yet unknown. Will be fixed later.

Summary of changes: - integration of Cisco work on nFAPI. See commits 7757b9e7 and 922b5b59 for details. - support Ubuntu 17.04 and 17.10 - bugfix: DCI padding bits This bug made the system non-working because the DCIs for SIBs were wrong. See commit c5ca2bd8 for details. - fix issue 281: IQ record/playback explicit filename segv.

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.

Basically, build_helper has been adapted so that: ./buil_oai -I -w USRP works for Ubuntu 17.04 and 17.10. Concerning those systems: - compilation with "--eNB --UE -w USRP" works - the enb softmodem runs on 17.04 (not tested on 17.10) - nothing else has been tested. Users should report any problem.

The problem is the following (as reported by an user): "one UE is attached to OAI system. UE is near the antenna. Try to detach the UE and attach again. Repeat this procedure for 5-6 times. OAI system does not work and any the UE can not attach to this system. I use TEMS software and I can see MIB signaling on this UE but UE can not decode SIB1 and SIB2." What happens is that the DCI for SIB1 and SIB2 is not cleared before use. That is the bits in the 'padding' field keep the values that were set before. If the structure has been used to transmit other DCIs (eg. for UEs) in the past, it may be reused with some of those bits set to 1. When receiving this DCI, the UE won't accept it because it gets some bits at 1 where it expects them to be 0. The short-term/quick solution is to clear the 'padding' field. A better solution would be to rewrite this part of the code, which is way too complicated for what it does. But this takes too much time. In dci.h the field 'dummy' of some structures was renamed to 'padding'. The fields 'padding32' and 'padding64' were also renamed to 'padding' for consistency. Some structures (DCI2B_1_5MHz_TDD, DCI2B_10MHz_FDD, DCI2D_1_5MHz_FDD, DCI2D_5MHz_FDD, DCI2D_10MHz_FDD) had a 'padding' field at the end, which was renamed to 'padding0'. I don't know if this field should be here at all. To me this field looks very suspicious. When we test DCIs 2B and 2D we should be careful.

physicalConfigDedicated may be legitimately NULL at some places with the current code. A cleaner solution is needed (we should always have a dedicated config, initialized with values from the 3GPP specs, not have a NULL as we do now).

Even if the old UE is not found, we have to cancel the random access.
