UCI Tx sequence Window (Advanced LTE TDD Uplink)

The UCI Tx sequence window displays the currently configured UCI transmission sequence. For the same UE, the UCI channel cannot be transmitted in subframes occupied by UL-SCH processes.

Select a UCI channel in the Channel Setup node, then click the button in the Transmission Configuration cell to open the UCI Tx sequence window.You can set parameters for each UCI transmission from within the UCI Tx sequence window.

Click the Config Tools button to access a drop-down list that enables you to set parameters for all UCI Tx sequences to the same value. The configured parameters are displayed in the Tx Map.
Use the Import tab to navigate to and import a saved transmission sequence.
Use the Export tab to save the current transmission sequence to a file.

Parameter Descriptions

State

Click the cell to toggle the state of the UCI Tx sequence on or off.

Format

Choice: 1 | 1a | 1b |2 | 2a | 2b

Default: 1a

Set the UCI format.

The Modulation type is set by the software based on the selected Format. See Modulation.

The choices available for the HARQ-ACK parameter are based on the selected Format. See HARQ-ACK.

RNTI

Range: 0 to 65535

Default: 0

Enter a value for the Radio Network Temporary Identifier (RNTI). RNTI only applies to format 2/2a/2b. See 3GPP TS 36.211.

Modulation

The modulation type for the UCI Tx sequence is set according to the active Format as follows:

Format 1 = N/A

Format 1a = BPSK modulation

Format 1b = QPSK modulation

Format 2 = QPSK modulation

Format 2a = QPSK + BPSK modulation

Format 2b = QPSK + QPSK modulation

Data Type

The software sets the Data Type according to the active Format, as follows:

Format 1 = SR

Format 1a = HARQ-ACK (1 bit)

Format 1b = HARQ-ACK (2 bits)

Format 2 with Extended Cyclic Prefix:

Select one of the following from the drop-down menu CQI | CQI + HARQ-ACK (1 bit) | CQI+ HARQ-ACK (2 bits)

Format 2a = CQI + HARQ-ACK (1 bit)

Format 2b = CQI + HARQ-ACK (2 bits)its)

Data

For Formats 2, 2a, or 2b, double-click in this cell to open a dialog box from which you can select PN9, PN15, or User Defined Bits as the data for the UCI TX sequence.

Data Size

Range:

1 to 13 bits (Formats 2, 2a, 2b with Normal Cyclic Prefix or Format 2 with Extended Cyclic Prefix and CQI Data Type)

1 to 12 bits (Format 2 with Extended Cyclic Prefix and CQI + HARQ-ACK (1 bit) Data Type)

1 to 11 bits (Format 2 with Extended Cyclic Prefix and CQI + HARQ-ACK (2 bits) Data Type)

Enter a value for Data Size for Formats 2, 2a,or 2b.

HARQ-ACK

Double-click the HARQ-ACK cell for the sequence you want to configure to open the HARQ-ACK Info Selection dialog box. Select the radio button in the dialog box for the desired HARQ-ACK. The choices available for HARQ-ACK are determined by the active Format as follows:

Format 1 or 2

HARQ-ACK parameter is grayed out (not used)

Format 1a or 2a

Choice: ACK | NACK

Default: ACK

Format 1b or 2b

Choice: ACK-ACK | ACK-NACK | NACK-ACK | NACK-NACK

nPUCCH(1)

Range: 0 to Max Resource Element - 1 - 1

Default: 0

Enter a value for the PUCCH n(1) number.

RB Location

Displays the numbers of the resource blocks occupied by the PUCCH, separated by a comma. If any of the following are changed: PUCCH Format, N_RB(2), N_CS(1), n(1), n(2), Delta Shift or Delta Offset, the resource block numbers are updated accordingly.

DMRS Power

Range: –60 to 0 dB

Default: 0 dB

Enter a power level in dB for the demodulation reference signal for the UCI Tx sequence.
