If a transmission scheme using several data streams is active, the parameter "MIMO
DL Stream" allows you to switch between the settings of the downlink streams. The
parameter is disabled if all streams use the same set of settings.

TTI-Based Channel Configuration
Before you start channel configuration, configure the duplex mode and the cell band-
width in the main view.
Then select the scheduling type and press the button "Edit All" in the "Connection
Setup" section of the main view. A dialog box for TTI-based channel configuration is
opened.
The button and the dialog box are available for the scheduling type "User-defined TTI-
Based" and all "CQI-PMI-RI" scheduling types ("Fixed CQI" and "Follow ...").
The dialog box contains several tabs, which are active or inactive, depending mainly
on the scheduling type and the scenario.
The tabs contain settings at the top and a graphical presentation of the resulting
resource block configuration at the bottom.
For valid parameter combinations and background information, refer to the following
sections:
●
chapter 2.2.13, "User-Defined Channels"
●
chapter 2.2.14, "CQI Channels"
DL Stream Tabs and UL Tab
The DL stream tabs and the UL tab contain usually one column of settings for each
subframe of a radio frame. For some transmission schemes, the DL stream tab con-
tains only one column, applicable to all subframes.
For TDD, the UL tab presents only the UL subframes of a radio frame, while the DL
tabs present both DL and special subframes. The special subframe settings configure
the DwPTS field for data transfer in downlink direction. To modify the uplink-downlink
configuration of the radio frame, see
"Uplink Downlink Configuration"
The subframe number (0 to 9) and the subframe type are indicated in the column
header. All columns must be configured top down (first # RB, then Start RB, then ...).
