DL-SCH Tx Sequence Window (Advanced LTE-A TDD Downlink)

Select a DL-SCH channel in the Channel Setup node, then click the button in the Transmission Configuration cell to open the DL-SCH Tx sequence window.  

The DL-SCH TX window displays the transmission sequence defined in the Channel Setup node for the selected DL-SCH channel.

The settings configured in the Channel Setup node and the DL-SCH Tx sequence window are displayed in the Tx Map.

• Use the Import button to navigate to and import a saved transmission sequence.

• Use the Export button to save the current transmission sequence to a file.

• Click the Column Preset button to access a drop-down list that enables you to set parameters for all transmissions to the same value.

  

See Parameter Descriptions below.
