1.2 R&S CMW Models
The R&S CMW software supports several instrument models. Depending on the
model, only a subset of the software packages and software options is allowed.
To check whether this document is relevant for your instrument model and which soft-
ware options are supported, refer to the preface of your model-specific base unit man-
ual. The PDF filename of this manual starts with CMW<Model>_UserManual, for
example CMW500_UserManual.
1.3 How to Read Firmware Application Chapters
Each firmware application is described in a separate chapter. These chapters can be
read independently of each other. However, they are all organized as follows:
1. General description
2. Application sheets (optional)
3. GUI reference
4. Programming examples
5. Command reference
How to Read Firmware Application Chapters

Preface
R&S®CMW-KM5xx/-KS5xx
11User Manual 1173.9628.02 ─ 24
The chapters "System Overview" and "Remote Control" in the R&S CMW base unit
manual provide additional important information independent of the individual firmware
applications. The most important parts are referenced by the firmware application
descriptions.
1.3.1 General Description
This section provides a general description of the firmware application, independent of
a specific operation mode (manual or remote control). It gives a high-level introduction
to the capabilities of the firmware application. Background information related to the
network standard is given as far as it is directly related to administrable parameters.
For measurement applications, a detailed description of measurement results and a
description of configurable limits is given, including the relation to conformance require-
ments defined in network standard specifications.
1.3.2 Application Sheets
This optional section provides short application examples for select issues and related
background information.
1.3.3 GUI Reference
The GUI reference describes the manual operation of the firmware application via the
graphical user interface (GUI).
The description of a configuration dialog usually starts with a screenshot presenting the
preset values of the parameters (sometimes preset values are modified to enable hid-
den parts of a dialog). Below the screenshot all shown parameters are described. For
each single parameter, a link to the corresponding command description in the com-
mand reference is provided. Ranges for numeric parameters and reset values are
given there.
For measurement results, links to the corresponding command descriptions are provi-
ded (commands to retrieve the results). The measurement results are described in
detail in the general description chapter.
1.3.4 Programming Examples
The programming examples show how to control and configure the firmware applica-
tion via a remote-control program and how to retrieve measurement results. The exam-
ples consist of comprehensive command sequences. You can check just a single com-
mand of a sequence to get an example for the syntax of this single command. But you
can also consider an entire sequence showing the commands in the context of a com-
mand script, under consideration of dependencies and required orders of the com-
mands.

12User Manual 1173.9628.02 ─ 24
The command sequences are written with the intention to list most commands of the
firmware application. They do not show the fastest way for a given configuration task.
The fastest way would use many reset values and omit the corresponding commands.
The examples are referenced by the command descriptions of the command refer-
ence.
1.3.5 Command Reference
The command reference provides information on the remote commands of the firm-
ware application. The commands are grouped according to their function.
Each command description indicates the syntax of the command header and of the
parameters. For input parameters the allowed ranges, reset values and default units
are listed, for returned values the expected ranges and default units. Most commands
have a command form and a query form. Exceptions are marked by "Setting only",
"Query only" or "Event". Furthermore, a link to the programming examples is provided
and the first software version supporting the command is indicated.

2 LTE Signaling
The LTE signaling firmware application emulates an E-UTRAN cell and communicates
with the UE under test. The UE can synchronize to the downlink signal and attach to
the PS domain. A connection can be set up (3GPP-compliant RMC or user-defined
channel).
Two basic signaling options are available: R&S CMW-KS500 for R8 FDD signals and
R&S CMW-KS550 for R8 TDD signals. At least one of these basic options is required
to use the signaling application. Both basic options support only configurations with a
single antenna (SISO).
The basic functionality can be enhanced via the following options:
●R&S CMW-KS502 adds support of DL carrier aggregation for FDD signals.
R&S CMW-KS552 adds support of DL carrier aggregation for TDD signals.
●R&S CMW-KS504 adds R12 features for FDD signals.
R&S CMW-KS554 adds R12 features for TDD signals.
●R&S CMW-KS510 provides advanced parameter settings for R8.
●R&S CMW-KS512 provides advanced parameter settings for R10, including UL
carrier aggregation.
●R&S CMW-KS520 adds support of DL MIMO 2x2 and SIMO 1x2.
R&S CMW-KS521 is required for DL MIMO 4x2 (prerequisite R&S CMW-KS520).
R&S CMW-KS522 is required for DL MIMO 8x2 (prerequisite R&S CMW-KS521).
●R&S CMW-KS525 adds a user-defined operating band and special bands.
●R&S CMW-KS590 is required for machine-type communication (MTC).
●R&S CMW-KE100 and R&S CMW-KE500 enable internal fading.
R&S CMW-KE501 is required for MIMO 4x2 fading (prereq. R&S CMW-KE500).
R&S CMW-KE502 is required for MIMO 8x2 fading (prereq. R&S CMW-KE501).
●R&S CMW-KS170 is required for cell broadcast services for alerting networks
Tests can be performed using the LTE multi-evaluation measurement, the PRACH
measurement or the SRS measurement (all included in the options R&S CMW-KM500
and R&S CMW-KM550).
Data transfer tests can be performed using the data application unit (DAU, option
R&S CMW-B450x and R&S CMW-KM050). The DAU also provides an IMS server for
voice over IMS and SMS over IMS. Audio tests can be performed using the audio
board plus a speech codec (R&S CMW-B400B and R&S CMW-B405A).
The "LTE signaling" application provides additional measurements. For details refer to:
●Chapter 2.3.1, "Combined Signal Path Measurements", on page 88
●Chapter 2.2.19, "Relative Power Control Tests", on page 71
●Chapter 2.3.2, "LTE IP-Based Data Tests", on page 92

2.2.1 Scenarios
The scenario selection is the first setting to be done for test configuration.
The LTE signaling application provides different scenarios for tests with or without
MIMO, fading and carrier aggregation (CA). The number of component carriers (CC) is
also selected via the scenario (one PCC + n SCC). Selecting a scenario hides/shows
parts of the GUI as required by the scenario.
The following table lists all available scenarios with a short explanation. The subse-
quent tables list the prerequisites for each scenario.

"1 Cell - IQ Out, RF In" RF uplink as for "1 Cell - 1 RF Out", baseband downlink via the I/Q board.
Allows you for example to insert an R&S SMU200A into the downlink path.
For all DL CA scenarios, you can also enable UL CA with two component carriers.
External fading can for example be added via a connected R&S SMW200A.
MIMO means always DL MIMO, not UL MIMO
The additional "Distributed" scenarios "2CC CA - 4 RF Out - Distributed" and "2CC CA - Fading - 4 RF Out - Distributed" are only
for backward compatibility. Do not use them any longer.
Which scenarios are offered for selection, depends on the available software and hard-
ware options. The following table lists all scenarios and the required options.
Additional hints:
●Single-CMW setups
A "1" in column "CMW" means, that the required hardware fits into a single instru-
ment. So these scenarios are available on a single-CMW setup, if the required
options are equipped.
The scenarios can also be used with a multi-CMW setup.
●Multi-CMW setups
A higher number in column "CMW" means that you need a multi-CMW setup with
at least the indicated number of instruments. The required hardware does not fit
into one instrument.
The instruments are controlled by an R&S CMWC. The test software including the
LTE signaling application is installed and executed on the R&S CMWC.
The options can be distributed over several instruments. But the signaling unit, TX
and I/Q board for each input or output path must be in the same instrument. For
one path, you cannot use for example an SUW of one instrument plus the I/Q
board of another instrument.
The SW licenses are pooled in the R&S CMWC, so it does not matter where they
are installed.

2.2.2.1 Test Setup for Scenario 1 Cell - 1 RF Out
The basic test setup for a "1 Cell - 1 RF Out" scenario uses a bidirectional RF connec-
tion between the tester and the device under test (DUT). It carries both the downlink
and the uplink signal:
●The R&S CMW transmits the downlink signal to which the DUT can synchronize to
perform an attach. The downlink signal is used to transfer signaling messages and
user data to the DUT.
●The DUT transmits an uplink signal that the R&S CMW can receive, decode and
analyze.
For this setup, the DUT is connected to one of the bidirectional RF COM connectors at
the front panel of the R&S CMW. No additional cabling and no external trigger are nee-
ded. The input level ranges of all RF COM connectors are identical.
See also: "RF Connectors" in the R&S CMW base unit manual, chapter "Getting Star-
ted"
Figure 2-1: Test setup for "1 Cell - 1 RF Out"
2.2.2.2 Test Setup for Scenario 1 Cell - 2 RF Out
The scenario "1 Cell - 2 RF Out" is used for setups with two UE RX antennas (SIMO
1x2, MIMO nx2 and beamforming). A test setup for this scenario involves one uplink
and two downlink signals at the UE side. Typically, one bidirectional connection carries
one uplink and one downlink signal. An additional connection carries the second down-
link signal. The two downlink signals must be transmitted via different TX modules and
different RF connectors, which implies that the instrument must support at least two TX
paths. You can use for example RF 1 COM for the bidirectional connection and RF 3
COM for the second downlink connection.

Using several signaling applications in parallel
Depending on the installed hardware and software options, you can run several signal-
ing application instances in parallel.
Example: Assume an instrument with two signaling unit wideband (SUW), one signal-
ing unit universal (SUU), four TX paths and four RX paths.
This instrument allows you to run for example:
●Two LTE signaling instances using the "1 Cell - 2 RF Out" scenario, or
●Two LTE signaling instances using the "1 Cell - 1 RF Out" scenario, plus one
instance of an SUU signaling application (e.g. GSM / CDMA2000)
●One LTE signaling instance using the "1 Cell - 2 RF Out" scenario, plus one
instance of an SUW signaling application (e.g. WCDMA)
●One LTE signaling instance using a carrier aggregation scenario with or without
MIMO
The LTE and WCDMA signaling applications both use the SUW. An SUW can only be
used by one instance at a time.
2.2.2.3 Test Setup for Scenario 1 Cell - 4 RF Out
The scenario "1 Cell - 4 RF Out" is used for MIMO 4x2 setups, where the four TX
antenna signals must be available at the RF connectors. Typically, an external RF
fader is inserted into the downlink connection and one bidirectional connection carries
one uplink and one downlink signal. Three additional connections carry the other
downlink signals.
All downlink signals must be transmitted via different TX modules and different RF con-
nectors. This requirement implies that the instrument must support four TX paths and
must be equipped with two signaling units.
Figure 2-3: Test setup for "1 Cell - 4 RF Out"
2.2.2.4 Test Setup for CA Scenarios (Single CMW)
The carrier aggregation (CA) scenarios allow you to establish a Release-10 connection
with several component carriers. A carrier can be a primary component carrier (PCC)
or a secondary component carrier (SCC).
Independent of the scenario, there is always one UL PCC and one DL PCC. For a CA
scenario, there is at least one additional DL SCC. If you enable UL carrier aggregation,
there is one additional UL SCC.

Depending on the scenario, a downlink carrier can have one output path (SISO) or two
output paths (for example MIMO nx2). In total, up to four output paths are supported.
Each output path must use a different TX module and each input path a different RX
module. The output paths of a carrier must use different RF connectors.
With an advanced frontend, you can route two paths to the same connector. This fea-
ture allows you to choose the optimum test setup depending on the number of antenna
connectors of your UE. There is no need for external combiners.
The following example setup is suitable for CA with four downlinks and a UE with only
two antenna connectors. There are two PCC downlinks (MIMO), two SCC downlinks
(one MIMO SCC or two SISO SCCs), one PCC uplink and one SCC uplink.
RF 1 COM is used for the uplinks, the first PCC downlink and the first SCC downlink.
RF 3 COM is used for the second PCC downlink and the second SCC downlink.
Figure 2-4: Test setup for CA, four DL, two UL, two DUT antenna connectors
For a UE with four antenna connectors, the following test setup could be used instead.
Each downlink signal is now routed to a different connector.
Figure 2-5: Test setup for CA, four DL, two UL, four DUT antenna connectors
For CA with one uplink and two downlinks, you could for example use only RF 1 COM
(uplink, PCC downlink and SCC downlink). Or you could use RF 1 COM (uplink and
PCC downlink) and RF 3 COM (SCC downlink).
2.2.2.5 Test Setup for CA Scenarios (Multi-CMW)
Some carrier aggregation scenarios require a multi-CMW test setup, comprising one
R&S CMWC plus several R&S CMW.
