General (Basic LTE FDD Uplink)

The General table in the uplink carrier node enables you to turn the uplink carrier on and off, select a saved channel configuration, and view the length of the generated waveform.

The Baseband parameters for the uplink carrier are described in Baseband (Basic LTE FDD Uplink).

State

Double-click or use the drop-down menu to turn the carrier Off or On.

Channel Configuration

Select a channel configuration with the desired modulation type, bandwidth, and number of resource blocks (RB) from the Closeddrop-down menu.

The User Defined setting is not selectable until certain parameters are changed, then User Defined is automatically set by the software.

Waveform Generation Length

Choice: 1 slot (0.5 ms) | 2 slots (1.0 ms) | … | 18 slots (9.0 ms) | 19 slots (9.5 ms) | 1 frame (10 ms)

Default: 1 frame (10 ms)

Displays the waveform generation length and this parameter is read only. The software sets the Total Sample Points based on the selected Waveform Generation Length and the Oversampling Ratio as below.

Total Sample Points = Base Sampling Rate (MHz) × Oversampling Ratio × 1000 × Waveform Generation Length (ms).

Figure 1 shows the generic frame structure.

Waveform Generation Offset

Range: 0 to 19 slots

Default: 0 slot

Sets the waveform generation offset.

When the waveform generation length or offset is set, Waveform Generation Length + Waveform Generation Offset <= 1 frame (10 ms) is automatically satisfied by the software.
