Antenna Port

Total number of Antennas

System Bandwidth

Total number of Resource Blocks

Total number of Occupied Sub-carriers

Subcarrier Spacing

Cyclic Prefix

Number of Subcarriers for Resource Block

Number of Symbols for Resource Block

PUSCH DFT Swap

Group/Sequence Hopping

nDMRS-CSH-Identity Enable

nDMRS-CSH-Identity (N_csh_DMRS_ID)

nDMRS(1)

Cell ID

Range: 0 to 503

Default: 0

Enter a value for the cell ID. See 3GPP TS 36.211.

Antenna Port

Choice: (It depends on Total Number of Antennas.)

0 (1 Antenna case)

0 | 1 (2 Antenna case)

0 | 1 | 2 | 3 | 4 (4 Antenna case)

Default: 0

Double-click or use the drop-down menu to set the antenna to be used for transmitting the uplink signal.

The available selections are determined by the Total Number of Antennas setting, see this parameter below.

When the MIMO Quick Setup is selected, this parameter is hidden.

See 3GPP TS 36.211 for more information.

Total number of Antennas

Choice: 1 Antenna | 2 Antennas | 4 Antennas

Default: 1 Antenna

Double-click or use the drop-down menu to set the total number of physical antenna port configuration used for uplink transmission in this cell.

When the MIMO Quick Setup is selected, this parameter is read-only.

See 3GPP TS 36.211 for more information.

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)

Use the drop-down menu to set the system bandwidth and number of Resource Blocks (RB).

When the system bandwidth is changed, the software automatically adjusts the value in the Total number of Resource Blocks cell, the Total number of Occupied Sub-carriers cell and so on.

The resource blocks and some parameters are reconfigured by changing the System Bandwidth parameter.

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

(1) When any action, Add CC, Delete CC, Copy CC, or Change System BW is executed and Auto Carrier Aggregation Configuration is on.

(2) When Auto Carrier Aggregation Configuration is changed to on from off.

Auto configuration sets the Cell ID to the same value as Component Carrier Index.

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

System Bandwidth is automatically set to 10 MHz or 20 MHz when Resource Allocation Type 3 is changed to on.

Resource Allocation Type 3 is automatically set to off when System Bandwidth is changed to a value other than 10 MHz or 20 MHz.

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.

Subcarrier Spacing

Default: 15 kHz

Displays the subcarrier spacing for the uplink. Only the 15 kHz subcarrier is supported in this release.

Cyclic Prefix

Choice: Normal | Extended

Default: Normal

Double-click or use the drop-down menu to select a Normal or Extended cyclic prefix. The software sets Number of Symbols for Resource Block based on the cyclic prefix selection.

Cyclic Prefix is automatically set to Normal when Resource Allocation Type 3 is changed to on.

Resource Allocation Type 3 is automatically set to off when Cyclic Prefix is changed to Extended.

See 3GPP TS36.211 5.2.4 for more information.

Number of Subcarriers for Resource Block

Default: 12

Displays the number of consecutive subcarriers in an uplink resource block.

Number of Symbols for Resource Block

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

Displays the number of consecutive OFDM symbols in a uplink slot. 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.

There are 17 different hopping patterns. If sequence or group hopping is disabled, sequence index 0 is used. If sequence or group hopping is enabled, the sequence index is given by the physical-layer cell identity.

See 3GPP TS36.211 for more information about Group Hopping and Sequence Hopping.

nDMRS-CSH-Identity Enable

Choice: On | Off

Default: Off

Double-click or use the drop-down menu to turn the flag which is whether nDMRS-CSH-Identity is enable or not. See 3GPP TS36.211 5.5.2.1.1 for more information.

Range: 0 to 509 Default: 0 Enter a value of nDMRS-CSH-Identity (N_csh_DMRS_ID). This parameter is active only when nDMRS-CSH-Identity Enable is on.

See 3GPP TS36.211 5.5.2.1.1 for more information.

nDMRS-CSH-Identity (N_csh_DMRS_ID)

Range: 0 to 509

Default: 0

Enter a value of nDMRS-CSH-Identity (N_csh_DMRS_ID). This parameter is active only when nDMRS-CSH-Identity Enable is on.

See 3GPP TS36.211 5.5.2.1.1 for more information.

nDMRS(1)

Choice: 0 | 2 | 3 | 4 | 6 | 8 | 9 | 10

Default: 0

Double-click or use the drop-down menu to select nDMRS(1) value which is given by 36.211 Table 5.5.2.1.1-2. This value is used for both PUSCH and PUCCH.

See 3GPP TS36.211 5.5.2.1.1, and 5.5.2.2.1 for more information.
