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.
Select QPSK, 16 QAM, or 64 QAM as the modulation type for the PDSCH.
Only frame 0 is available for the Basic LTE Downlink carrier.
Enter a subframe number for the PDSCH.
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).
