- the RU now supports IF equipment with custom FR1 TX/RX frequencies
- this configuration parameter together with the if_freq parameter allows
to set a custom IF RX frequency for the gNB
- if the IF offset is not specified, legacy code applies
ignoring command line paramters clock_source and time_source in lte-softmodem and harmonizing it with nr-softmodem
time_source and clock_source handled separately in usrp_lib.cpp
- physical simulators
- LTE eNB
- LTE UE
- 5G-NR gNB
Still NR-UE does not build and eNB segs fault at start of program

In the configuration file, to enable measurements, add:
enable_measurement_reports = "yes";
Note that if x2 is enabled then the option 'enable_measurement_reports'
is not taken into account and the measurements are enabled.

removed XFORMS from lte-softmodem target and associated extra functions in lte-softmodem.c

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.
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
