Uplink (Basic LTE-A Pro FDD)

Click Uplink in the tree view to open this property grid, enabling you to set cell parameters and sounding reference signal parameters.

Accesses a Closeddialog box from which you can select a base channel configuration.

UL RMC Wizard

Opens the UL RMC Wizard.

1. Cell Parameters

Cell ID

Range: 0 to 503

Default: Same as CC index (when Auto Carrier Aggregation Configuration is on), otherwise it is 0

Enter a value for the Cell ID.

The software sets the values in the Physical Layer Cell ID Group and Physical Layer Cell ID Sector cells based on the Cell ID entry. Cell ID = (3 x Physical Cell ID Group) + Physical Cell ID Sector.

See 3GPP TS 36.211 for more information.

Frequency Offset and Cell ID are always editable, even if Auto Carrier Aggregation Configuration is on.

In the case (1) or (2), auto configuration is done for Frequency Offset and Cell ID.

(1) When any action "Add CC" or "Delete CC" or "Copy CC" or Change System BW is done and Auto Carrier Aggregation Configuration parameter is On.

(2) When Auto Carrier Aggregation Configuration parameter is changed to On from Off.

Auto configuration sets Cell ID same as Component Carrier Index.

If Auto Carrier Aggregation Configuration is set to off, auto configuration does not work.

RNTI

Range: 0 to 65535 (0xFFFF)

Default: 0

Enter a decimal value for the Radio Network Temporary Identifier (RNTI).

System Bandwidth

Choice: 1.4 MHz (6RB) | 3 MHz (15RB) | 5 MHz (25RB) | 10 MHz (50RB) | 15 MHz (75RB) | 20 MHz (100RB)

Default: 10 MHz (50RB)

Double-click or use the drop-down menu to set the system bandwidth and number of Resource Blocks (RB). When you select a system bandwidth, the software automatically adjusts the value in the Total number of Resource Blocks cell and the Total number of Occupied Sub-carriers cell.

When the System Bandwidth is decreased, the UL-SCH Tx Sequence window's RB size, and some of the other data channel's settings, are reconfigured, similar to when a Predefined Configuration is executed. But when the System Bandwidth is increased, no change occurs to the UL-SCH Tx Sequence window's RB size or other data channel settings.

Total number of Resource Blocks

The value in this cell is set by the software based on the System Bandwidth setting.

Total number of Occupied Sub-carriers

The value in this cell is set by the software based on the System Bandwidth setting.

Number of Symbols for Resource Block

Default: 7 for Normal Cyclic Prefix; 6 for Extended Cyclic Prefix

Displays the number of consecutive symbols in the uplink resource block. The software sets the Number of Symbols for Resource Block based on the Cyclic Prefix selection.

PUSCH DFT Swap

Choice: Off | On

Default: On

Double-click or use the drop-down menu to turn PUSCH DFT Swap on or off.

PUSCH DFT Swap influences how data is mapped to resource elements in the physical uplink shared channel after discrete Fourier transform is performed. PUSCH DFT Swap can be turned on or off to provide two different interpretations of how data should be mapped to resource elements in PUSCH channels. For details about this feature, contact your Keysight representative.

Group/Sequence Hopping

Choice: Off | Group Hopping | Sequence Hopping

Default: Off

Set one or both of the following parameters to On to allow manual control of Hopping:

Double-click or use the drop-down menu to select Group Hopping or Sequence Hopping or to turn hopping Off.
