DL-SCH PDCCH Tx Setting and Configuration (Advanced LTE-A TDD Downlink)

Select the DCI channel in the Channel Setup node, then click the button in the DCI #n for DL-SCHn Scheduling cell to open the DL-SCH PDCCH Tx Setting window (i.e. where n = 1 to 11).

The DL-SCH PDCCH Tx Settings window display the parameters setting of PDCCH transmitted in each subframe for the related DL-SCH channel in the Channel Setup Node.

Use the Import button to navigate to and import a saved transmission sequence.
Use the Export button to save the current transmission sequence to a file.
Click the Config Tool button to access a drop-down list that enables you to set parameters for all transmissions to the same value.

1. DCI Settings

DCI State

Double-click or use the drop-down menu to control the operating state of DCI channel.

DCI Format

Default: Format 1A

Double-click or use the drop-down menu to set the Format of the DCI. The available DCI formats are different with different resource allocation types.

Refer to 3GPP TS 36.213 7.1 for more information about the DCI format selection under different transmission modes.

DCI Data

Display the Data Source of the DCI channel..

DCI Payload Size (bits)

Display the payload size in bits. Refer to the 3GPP technical standards for more information.

RNTI

Range: 1 to 65535

Default: 1

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

The parameter is coupled with the parameter RNTI in the DL-SCH setting.

2. PDCCH Settings

DCI Tx Couple

Choice: DL-SCH | Manual

Default: DL-SCH

Double-click or use the drop-down menu to set the transmission couple state between DCI and DL-SCH.

The parameter is coupled with the parameter DCI Tx Couple in the DL-SCH setting.

If the DCI Tx Couple is DL-SCH, the transmission state of DCI and DL-SCH will be coupled when you set the transmission state of PDCCH or PDSCH in each subframe.

PDCCH UE Tx Antenna

Choice: UE Port 0 | UE Port 1

Default: UE Port 0

Double-click or use the drop-down menu to set the UE Tx Antenna for the DCI channel.

The parameter is coupled with the parameter PDCCH UE Tx Antenna in the DL-SCH setting.

Search Space

Choice: Common | UE Specific

Default: UE Specific

Double-click or use the drop-down menu to set the search space of the PDCCH channels.

Search Space is only available to be set when the current component cell is set to be the Primary Cell component carrier. For secondary cell component carriers, this parameter is inactive.

The parameter is coupled with the parameter PDCCH Search Space in the DL-SCH setting.

See more details about this parameter in the PDCCH Assignment Procedure in 3GPP TS 36.213 9.1.1.

PDCCH Tx Parameter Settings

State

Choice: Off | On

Default: On

Click to turn the DCI state on or off in the selected subframe.

PUCCH TPC

Choice: TPC #0 (-1 dB) | TPC #1(0 dB) | TPC #2 (1 dB)| TPC #3 (3 dB)

Default: TPC #0 (–1 dB)

Select the TPC command for PUCCH in the selected subframe.

DAI

Choice: 0 to 3

Default: 0

Set the Downlink Assignment Index field of the DCI information in the selected subframe.

Scrambling Identity

Range: 0 to 1

Default: 0

Enter a value of the Scramble ID for UE-specific Reference Signals (DM-RS).

This parameter indicates the Scramble ID for DM-RS and is only available when:

DM-RS Antenna Port = Port 7 or Port 8 and
DCI Format = 2B or 2C.

See 3GPP TS 36.211 and 36.213 for more information.

PMI Confirmation

Choice: Indicate in TPMI | Indicate in latest PMI on PUSCH

Default: Indicate in TPMI

Set the PMI Confirmation type of PDSCH in the selected subframe.

The parameter is only available when the DCI format is 1B.

DL Power Offset

Choice: –10log10(2) dB| 0 dB

Default: 0 dB

Set the DL power offset of PDSCH in the selected subframe.

The parameter is only available when the DCI format is 1D.

CW Swap

Choice: –10log10(2) dB| 0 dB

Default: 0 dB

Click to set the codeword swap state of PDSCH in the selected subframe.

The parameter is only available when the DCI format is 2 or 2A.

If the code word swap state is true, the information of the transmission block will be swap in the DCI content.

Agg Level

Choice: 1 | 2 | 4 | 8

Default: 1

Select the Aggregation level for the DCI searching space in the selected subframe.

See more details about this parameter in the PDCCH Assignment Procedure in 3GPP TS 36.213 9.1.1.

Candidate

Choice: 0

Default: 0 to maximum

Set the candidate within the searching space in the selected subframe.

See more details about this parameter in the PDCCH Assignment Procedure in 3GPP TS 36.213 9.1.1.

CCE Offset

Displays the CCE offset of the DCI in the selected subframe.

See more details about this parameter in the PDCCH Assignment Procedure in 3GPP TS 36.213 9.1.1.
