UL-SCH Tx sequence Window (Advanced LTE-A FDD Uplink)

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

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

You can make adjustments to the MCS index, VRB offset for slot 0 and slot 1, and other parameters for each UL-SCH transmission from within the UL-SCH Tx sequence window.

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

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

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

Use the Export tab to save the current transmission sequence to a file.
