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.

For whatever reason most of the files had their permission changed from 644 to 755, which is not wanted.

For whatever reason we need N_TA_offset to be 0 for the basic simulator to function properly. This is more a hack than a proper solution. More analysis is needed to understand what happens and what should be really done.

* join pthread_FH (ru_thread) once all condition variables have been set * join RU FHTX only if it has been started (check as for pthread_create()) * join PRACH thread in the monolithic case * send broadcast on condition variable cond_eNBs, as there can be multiple waits on it * integrate stop_ru(*ru) into kill_RU_proc(*ru) * Correct memory freeing

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
