Using a Standard Setup (LTE-Advanced)
To select an LTE Long Term Evolution-Advanced preset configuration for a component carrier:
- Set Duplex Mode to or
- Set Direction to or
-
Click
- Select a Component Carrier button at the top of the tab
- Click and select a bandwidth
Below is a list of available bandwidths that an LTE-Advanced component carrier can be preset to.
Available Bandwidths |
---|
1.4 MHz Megahertz: A unit of frequency equal to one million hertz or cycles per second. (6 RB Resource Block) |
3 MHz (15 RB) |
5 MHz (25 RB) |
10 MHz (50 RB) |
15 MHz (75 RB) |
20 MHz (100 RB) |
In addition to bandwidth, presetting the component carrier's bandwidth also sets the measurement parameters to the default values listed in the following section. Click on one of the links below to jump to the corresponding table.
