2. Almost Blank Subframe (ABS) Settings |
|---|
Choices: On | Off
Default: Off
Set whether to use ABS (almost blank subframe) for each component carrier by clicking the cell and then the drop-down arrow 
to make the selection:
|
|
Off |
|
ABS is disabled and its related settings are inactive (nothing shows). |
|
|
On |
|
ABS is available for the component carrier, and its related settings are active. |
When the component carrier ABS state is on, the Transmission Configuration Length for all DL-SCH becomes a read-only value that is set to the same length as the Waveform Generation Length.
This property is also available in the Carrier Aggregation node.
Default: 40-bits all 0
Coupling: Inactive until ABS is On
Set the ABS bit pattern for the corresponding component carrier by clicking the cell and then the dialog box button 
. This launches the 
Bitmap Edit dialog box that is used to enter up to 40-bits.
Each bit position represents a subframe. Use the keyboard to enter either a 0 or a 1.
|
|
0 |
|
ABS is not applied to the subframe. |
|
|
1 |
|
ABS is applied to the subframe. |
Within the Bitmap Edit dialog box are the two buttons Import and Export:
Import allows the loading of a previously saved bitmap.
Export allows the saving of the current bitmap.
The first position of the ABS pattern corresponds to subframe 0 where SFN = 0. The ABS pattern is continuously repeated during the Transmission Configuration Length of the DL-SCH. For example, if the Transmission Configuration Length is 120 ms and there are 30-bits in the ABS pattern, the ABS bit pattern would repeat four times.
Per the 3GPP standards, ABS is designated as protected from inter cell interference from the sending eNB.
This property is also available in the Carrier Aggregation node.
Choices: On | Off
Default: Off
Coupling: Inactive until ABS is On
Click the cell to show the drop-down arrow that when clicked displays the choices to either enable or disable PSS/SSS during the ABS for the corresponding component carrier.
This property is also available in the Carrier Aggregation node.
Choices: On | Off
Default: Off
Coupling: Inactive until ABS is On
Click the cell to show the drop-down arrow that when clicked displays the choices to either enable or disable PBCH during the ABS for the corresponding component carrier.
This property is also available in the Carrier Aggregation node.
