Configure PDSCH Window (Basic LTE-A FDD Downlink)

Before adding a PDSCH channel as described below, delete the default DL-SCH channel in the Transport Channel node (or any configured DL-SCH that occupies resource blocks that your new PDSCH will occupy). If you add a new PDSCH without deleting a conflicting DL-SCH, a "code conflicted" error appears in the Status Bar and the Status Window when you generate the waveform.

Click the Add Channel button in the Physical Channel node and select PDSCH to open the Configure PDSCH window. The following figure shows the Configure PDSCH window with the default settings after deleting the DL-SCH channel. The currently configured PDSCH is shown in yellow in the resource mapping graph at the bottom of the window.

Modulation Type

Choices: QPSK |16QAM | 64QAM | 256QAM

Default: QPSK

Select the modulation type for the PDSCH.

256QAM appears in the software's GUI only when Minor Enhancement Update (MEU) Option U03 or greater is valid. Refer to Licenses for more information.

Frame Number

Only frame 0 is available for the Basic LTE Downlink carrier.

Subframe Number

Enter a subframe number for the PDSCH.

Resource Blocks

Enter the number(s) of the resource blocks for the PDSCH to occupy in both slots of the subframe. You can enter multiple resource blocks, separated by commas (for example 1,3,5) or a range of resource blocks (for example 1-5).
