2 About OneWeb option
The OneWeb option enables you to generate signals based on the OneWeb specification.
● Required options..................................................................................................... 11
● Provided reference signals......................................................................................11
2.1 Required options
The basic equipment layout for generating signals according to the OneWeb specifications includes the options:
●
Standard or wideband Baseband Generator (R&S SMW-B10/-B9)
●
Baseband Main Module (R&S SMW-B13) or Wideband baseband main module
(R&S SMW-B13XT)
●
Option OneWeb reference signals (R&S SMW-K355)
●
Option OneWeb user-defined signal (R&S SMW-K130)
●
Frequency option (e.g. R&S SMW-B1003)
About OneWeb option
Provided reference signals
You can generate signals via play-back of waveform files at the signal generator. To
create the waveform file using R&S WinIQSIM2, you do not need a specific option.
To play back the waveform file at the signal generator, you have two options:
●
Install the R&S WinIQSIM2 option of the digital standard, e.g. R&S SMW-K255 for
playing LTE waveforms
●
If supported, install the real-time option of the digital standard, e.g. R&S SMW-K55
for playing LTE waveforms
For more information, see data sheet.
2.2 Provided reference signals
For an overview of the supported reference signals depending on the installed options,
see Table 2-1.

With enabled signal generation, triggers the instrument to save the current settings of
an arbitrary waveform signal in a waveform file with predefined extension *.wv. You
can define the filename and the directory, in that you want to save the file.
Using the ARB modulation source, you can play back waveform files and/or process
the file to generate multi-carrier or multi-segment signals.

Overview of the scheduling methods
In the R&S SMW, there are different approaches to configure and schedule the different PDSCH allocations:
●
According to the configuration made for the DCIs ("Auto/DCI")
22User Manual 1178.5714.02 ─ 08
R&S®SMW-K130/-K355
This mode assures a OneWeb signal and the PDSCH allocations are configured
automatically according to the configuration of the PDCCH DCIs.
There are however limitations in the configuration flexibility, especially regarding
the power setting, see "Limitations and interdependencies in the Auto/DCI and
Auto Sequence modes" on page 23.
Limitations and interdependencies in the Auto/DCI and Auto Sequence modes
The generation of a compliant signal requires some limitations in the configuration flexibility, especially regarding the power setting:
●
The value of the parameter Reference Signal Power is fixed to 0dB.
●
The PDSCH Power of each allocation belonging to a user is set as configured with
the parameter Power for the corresponding user in the "Configure User" dialog.
●
All four users are activated with enabled Scrambling and Channel Coding.
●
Not all combinations of DCI Table, Users and UE_ID/n_RNTI are allowed, see
