Transmission Mode
Selects the LTE transmission mode. The available values depend on the active sce-
nario, see
In the state "Connection Established", the parameter can be changed within the follow-
ing groups: Mode 1/7, Mode 2/3/4/6/8.
The transmission mode 8 cannot be combined with an extended cyclic prefix (combina-
tion not foreseen by 3GPP).
Remote command:
DCI Format
Selects the Downlink Control Information (DCI) format. The available values depend on
the transmission mode. For most transmission modes, the DCI format is fixed.
For scheduling type "Follow WB CQI-RI", only DCI format 2A is supported. Changing
the format to 1A modifies the scheduling type.
Remote command:
Antenna Configuration
Selects the number of downlink TX antennas. The allowed values depend on the
selected scenario and transmission mode.
The number of downlink RX antennas depends on the selected scenario and is dis-
played for information.
For MIMO 4x2, option R&S CMW-KS521 is required.
For transmission mode 7 and 8, the parameter is irrelevant and hidden.
Remote command:
Transmission Scheme
Displays the PDSCH transmission scheme resulting from the settings.
The displayed value does not reflect transmission scheme changes due to reported
rank indicator values. TM4 combined with follow RI and RI=1 results in transmit diver-
sity.
Remote command:
Graphic
The graphic shows the logical signal path of the data streams via the virtual eNodeB
antennas and the RF output connectors to the antenna connectors of the UE.
Remote command:
