Subframe Configuration
Add
Click the 
Add button a subframe configuration. One or more subframe configurations can be added/ removed/ duplicated to fill the whole frame resource.
For each subframe configuration, the following properties can be configured:
Enabled
Select/ deselect the Enable check box to enable/ disable the channel or signal in a radio frame.
xPRACH configuration is mutual exclusive to other configurations. That mean, when xPRACH is enabled, all the other configurations will be turned off.
Assigned Subframes
Indicate which subframes will be assigned with this configuration type. The format is:
-
Subframe number is separated by ‘,’
-
Range of subframes is expressed by ‘start:(step:)end’
When there is a conflict occurs, i.e. one subframe is assigned with two or more configurations, the row of configuration with conflict will become red. User needs to resolve the conflict before generating the waveform.
Description
For downlink/ uplink configurations, it displays the symbol allocation within the subframe.
For other configurations, it displays the available channels in the subframe.
-
Dc = downlink control
-
Dd = downlink data
-
Uc = uplink control
-
Ud = uplink data
-
C.RS = CSI-RS
Delete
Select a subframe configuration and click the Delete button to delete it.
Copy
Select a subframe configuration and click the Copy button to make a copy of it.
Graphical Display
Graphical display for the whole frame is located at the bottom part under Carrier node and Subframe Configuration node. It displays the resource allocation for each channel in time/frequency 2-dimension resource grid. The X axis is subframe and Y axis is physical RB.
Each channel in the graphical display uses the same color as its channel block.
Since the graphical panel can only display 10 subframes at a time, to view the whole radio frame, a sliding bar is provided on the top of the panel. User can click any subframe number in the sliding bar or drag-and-drop the white sliding window, then the graphical panel will display 10 subframes within the sliding window.
When mouse is hovering on a specific channel, it will show the channel name in a tooltip.
