When pushing traffic with iperf the UE was crashing. The argument passed to pthread_mutex_timedlock is absolute time based on the CLOCK_REALTIME timer, not relative time. That seems to be the root cause of the bug. (That there is a timeout is another story.) This commit uses absolute value. Also we separate cases between IS_SOFTMODEM_BASICSIM / IS_SOFTMODEM_RFSIM and standard realtime UE. In the 'sim' modes we don't care about timeout and just call pthread_mutex_lock. It seems to be the idea of the original work. If not, then to be fixed.

* Instead of partly initializing in read_config_and_init(), everything of PDCP is initialized in main() of lte-softmodem * Omit RC.rrc access in RRU through checking of RC.nb_inst > 0 * Includes FlexRAN, i.e. do not start FlexRAN in RRU * Function pointers to PDCP functions have to be set explicitly (avoid confusion of multiply setting function pointers)

Not much major changes. In openair1/PHY/LTE_UE_TRANSPORT/dci_tools_ue.c, in the function generate_ue_dlsch_params_from_dci, 'harq_pid' was removed and dci_info_extarcted.harq_pid is now used for all cases. The ue T tracer only deals with PHY signals (no MAC, RLC, PDCP, RRC).

end_of_burst_delay is used to stop TX only "after a while". If we stop right after effective signal, with USRP B210 and B200mini, we observe a high EVM on the S subframe (on the PSS). A value of 400 (for 30.72MHz) solves this issue. This is the default. This default value can be changed in the configuration file. For example: RUs = ( { local_rf = "yes" nb_tx = 1 nb_rx = 1 att_tx = 20 att_rx = 0; bands = [7]; max_pdschReferenceSignalPower = -27; max_rxgain = 105; eNB_instances = [0]; sf_extension = 312; end_of_burst_delay = 200; } ); Here we would set a value of 200. The value to put in the configuration file is for 30.72MHz. The value is scaled accordingly at runtime (thus only one value to set for every RB configuration, 25, 50 or 100, leading to less problems when adapting configuration files). This option is for experts and should not be changed randomly.

Start of burst is to start TDD DL transmission in the driver (tested with USRP for the moment). End of burst is to stop DL transmission. Start of burst can only happen for a DL subframe when the previous subframe was an UL subframe. End of burst can only happen for an S subframe. It's impossible for a subframe to be both the start of a burst and the end of a burst. This can be checked with eg. http://niviuk.free.fr/lte_resource_grid.html (or reading the specs).

This parameter is meaningful in TDD, to decide when to start DL at eNB side. Since there is a need for the PA to be operational, we need to transmit a bit before the DL subframe coming after an UL subframe. (We transmit zeros.) We used to use N_TA_offset which may be too much. Default value is now N_TA_offset/2 and can be changed in the configuration file, in the RUs section, like: RUs = ( { local_rf = "yes" nb_tx = 1 nb_rx = 1 att_tx = 0 att_rx = 0; bands = [7]; max_pdschReferenceSignalPower = -27; max_rxgain = 105; eNB_instances = [0]; sf_extension = 312; } ); N_TA_offset is 624 (for 30.72MHz). In the example above, we set sf_extension = 312, which is also the default. The value to put in the configuration file is for 30.72MHz. The value is scaled accordingly at runtime (thus only one value to set for every RB configuration, 25, 50 or 100, leading to less problems when adapting configuration files). This option is for experts and should not be changed randomly.
