Channel Setup – Advanced Downlink Carrier

Advanced downlink carriers consist of the following:

• Adv W-CDMA/HSDPA DL Rel 6

• Adv W-CDMA/HSPA+ DL Rel 10

This topic describes the parameters available in the advanced downlink channel setup node.

Channel Configuration Summary Table

This table enables you to view the key parameters for each channel in a carrier. All of the advanced downlink carrier channel configurations (RMC/RMC+HSET) are created in accordance with the 3GPP standards.

This button opens a window of predefined channel configuration selections according to the selected carrier type:

• Adv W-CDMA/HSDPA DL Rel 6

  

• Adv W-CDMA/HSPA+ DL Rel 10

  

Double-clicking a configuration or clicking OK replaces the current configuration in the setup table. Select the carrier type from the Waveform or Carrier views.

This button opens a drop-down menu for selecting a channel to add to the setup table. The channel is inserted above the currently highlighted channel in the table.

This button deletes the currently highlighted channels in the setup table. You can highlight multiple channels by holding down the CTRL key while selecting the channels. You can also use the SHIFT key to select a succession (group) of channels.

This button is only available for Adv W-CDMA/HSPA+ DL Carrier Rel 10. You can normalize power (relative power) to make the total power 0dB.

3GPP

Absolute Grant Scope

Range: 0, 1

Default: 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0

For the E-AGCH channel, this cell sets the Absolute Grant Scope pattern.

Absolute Grant Value

Range: 0, 1, 2, ..., 31

Default: 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0

For the E-AGCH channel, this cell sets the Absolute Grant Value pattern.

Alternative UE ID

Range: 0 to 65535

Default: 65535

For the HS-SCCH channel, this cell sets the identity of the UE different from the UE under test.

ARQ Type

Choices: NONE | HARQ

Default: HARQ

Double-click or use the drop-down menu to select the ARQ Type. This setting is available on the HS-PDSCH with the HSDSCH data selection and available on the HS-SCCH with the STD data selection.

NONE	HARQ settings are inactive (greyed out) and ignored by the software
HARQ	HARQ settings are active: HARQ: Maximum Number of HARQ Transmission HARQ: Redundancy Version Parameter Sequence HARQ: ACK/NACK Pattern

Because the HS-SCCH uses the HARQ setting in its coding, it is always available on this channel with the STD data selection. However if the HS-DSCH is not the HS-PDSCH data type, the HS-PDSCH does not broadcast the HARQ even if the HS-SCCH setting is HARQ.

This setting is coupled between the HS-SCCH and the HS-PDSCH so that if it is set on one channel, it also changes the setting on the other channel.

BCH Block Size

For the P-CCPCH channel, this cell only provides information (not editable) on the BCH block size in the current predefined channel configuration, which complies with the 3GPP standards. The information in this cell is fixed, and only visible and relevant when BCH is the data selection for the Data cell.

BCH Coding Type

For the P-CCPCH channel, this cell only provides information (not editable) on the BCH coding type in the current predefined channel configuration, which complies with the 3GPP standards. The information in this cell is fixed, and only visible and relevant when BCH is the data selection for the Data cell.

BCH CRC

For the P-CCPCH channel, this cell only provides information (not editable) on the BCH cyclic redundancy bits in the current predefined channel configuration, which complies with the 3GPP standards. The information in this cell is fixed, and only visible and relevant when BCH is the data selection for the Data cell.

BCH Data

Choices: PN9 | PN15 | BCCH-BCH-Message| User Defined Bits

Default: BCCH-BCH-Message

This cell is available only when BCH is the current data selection for the P-CCPCH.

For the P-CCPCH channel type, when you click the cell, a dialog box button ( ) appears and provides access to Data Source Selection dialog box where you select the data type.

BCH Number of Blocks

For the P-CCPCH channel, this cell only provides information (not editable) on the BCH number of blocks in the current predefined channel configuration, which complies with the 3GPP standards. The information in this cell is fixed, and only visible and relevant when BCH is the data selection for the Data cell.

BCH Rate Matching Attribute

For the P-CCPCH channel, this cell only provides information (not editable) on the BCH rate matching attribute in the current predefined channel configuration, which complies with the 3GPP standards. The information in this cell is fixed, and only visible and relevant when BCH is the data selection for the Data cell.

BCH TTI

For the P-CCPCH channel, this cell only provides information (not editable) on the BCH TTI in the current predefined channel configuration, which complies with the 3GPP standards. The information in this cell is fixed, and only visible and relevant when BCH is the data selection for the Data cell.

Block Number of Max TF

Range: 0 to 512

The behavior of this parameter is dependent upon the Transport Position selection.

Fixed Transport Position

This sets the block number of the TF which has the maximum transport bits in the TFS, this parameter is used to calculate the rate matching parameter max Nijtti for fixed positions of TrCHs. For more information, refer to 4.2.7.2.1.1 in TS 25.212.

For DPCH, take the following TFS for example, the Block Number of Max TF shall be set to 1, the Block Size of Max TF shall be set to 81.

TFS	TF0	0x0
	TF1	1x39
	TF2	1x81

For S-CCPCH, take the following TFS for example, the Block Number of Max TF shall be set to 3. The same Block Size is applied to multiple blocks in the TFS of S-CCPCH.

TFS	TF0	0x168
	TF1	1x168
	TF2	2x168
	TF3	3x168

Flexible Transport Position

This sets the block number of the TF, which has the maximum sigma (RMi*Nij) in the TFCS and it is used to calculate RFi (see 4.2.7.2.2.1 in TS 25.212).

The following example shows the TFS for two transport channels mapped to an S-CCPCH:

TFS of TrCH1	TF0	0x168
	TF1	1x168
	TF2	2x168
	TF3	3x168
TFS of TrCH2	TF0	0x360
	TF1	1x360

From the above table, the TFCS would be as follows:

• (TF0, TF0)

• (TF1, TF0)

• (TF2, TF0)

• (TF3, TF0)

• (TF0, TF1)

• (TF1, TF1)

From the above list, using the TFC (TF1, TF1) with the formula shown in TS 25.212, 4.2.7.2.2.1, the value for the Block Number of Max TF setting for each transport channel is 1.

But if the TFCS were to change to allow the following combinations:

• (TF0, TF0)

• (TF1, TF0)

• (TF2, TF0)

• (TF3, TF0)

• (TF0, TF1)

• (TF1, TF1)

• (TF2, TF1)

• (TF3, TF1)

TFC (TF3, TF1) when used in the same formula, would make the value of the Block Number of Max TF setting 3 and 1.

It is similar for the DPCH, but with the addition of the Block Size of Max TF parameter, which sets the TF block size. This is required to fulfill the values for the formula from TS 25.212, 4.2.7.2.2.1.

Block Size

Range: 1 to 5000

Default: 244

For the HS-PDSCH, this cell only displays the block size of HS-DSCH. The block size depends on the block size information (Block Size Info) carried in the HS-SCCH and the modulation setting of the HS-PDSCH. The displayed block size is only valid for an HSDSCH Data selection.

The HS-SCCH uses the Block Size values in its coding even when the HS-DSCH is not the HS-PDSCH data type.

Block Size Info

Range: 0 to 63

Default: 0

Sets the block size of HS-DSCH and the Block Size Info coded in HS-SCCH.

When the Base Channel Configuration is of type 'RMC+HSET', the fixed value is still used in the coding of the HS-SCCH.

Block Size of Max TF

Range: 1 to 5000

The behavior of this parameter is dependent upon the Transport Position selection and it is used in combination with the Block Number of Max TF parameter.

Fixed Transport Position

Sets the block size of the TF which has the maximum transport bits in the TFS.

This parameter is just used to calculated the rate matching parameter max Nijtti for fixed positions of TrCHs. For more information, refer to section 4.2.7.2.1.1 in TS 25.212.

For DPCH, take the following TFS for example, the Block Size of Max TF shall be set to 81, the Block Number of Max TF shall be set to 1.

TFS	TF0	0x0
	TF1	1x39
	TF2	1x81

Flexible Transport Position

This sets the block size of the TF, which has the maximum sigma (RMi*Nij) in the TFCS and it is used to calculate RFi (see 4.2.7.2.2.1 in TS 25.212).

Block Size Reference

Range: 0 to 3

Default: 0

Sets the block size reference coded in HS-SCCH Type 2. For more information, refer to section 4.6A.2.2.1.1 in TS25.212.

Block Size Table Type

Range: Bit_Aligned | Octet_Aligned

Default: Bit_Aligned

Sets the transport block size table of HS-DSCH.

Channel Number

View the channel number of the displayed parameters. The software accepts a maximum of 512 channels. You can change the channel configuration or add individual channels using the buttons at the top of the data summary table.

CRC Method

This is a read only setting. The software displays and sets this parameter to Method 2 when the HS-SCCH Type is set to 2 (HS-SCCH less mode). When it is not displayed (HS-SCCH Type 1 or 3 selection), the software uses CRC Method 1.

This parameter is available with only the Adv W-CDMA/HSPA+ DL Rel 10 carrier.

All Other Channels

Range: 0 to 149

Enter a value to set a timing offset for the selected channel. Each integer value entered is equivalent to 256 chips or 1/10 of a timeslot offset.

The timing offset affects the crest factor of the signal. By varying the timing offset, the probability of channels adding in phase and producing a high peak-to-average ratio or crest factor is minimized. Base stations vary the timing between channels so that amplifiers can operate at the most efficient level.

TPC

Range: 0000 to 7FFF

Enter the TPC value for the OCNS channel.

TPC Number of Steps

Range: 1 to 80

Default: 1

For the DPCH channel and the F-DPCH channel, this cell sets the number of up and down power steps for the TPC Pattern selections Up/Down and Down/Up. For example with this cell set to 20 and the TPC Pattern set to Up/Down, the signal source transmits a power pattern that tells the basestation to step-up the power up in 1 dB increments for 20-steps and then down for 20-steps. The signal repeats this pattern until the parameter changes or the signal terminates.

TPC Pattern

Choices: Up/Down | Down/Up | All Up | All Down | User Defined Bits

Default: Up/Down

For the DPCH channel and the F-DPCH channel, this cell sets the TPC (transmit power control) pattern. This pattern instructs the base station to increase or decrease its power in 1 dB increments. When you click the cell, a dialog box button () appears and provides access to the TPC Selection dialog box where you can select from the following choices:

Up/Down	This choice repetitively steps up and down the TPC pattern. Use the TPC Number of Steps cell to set the number of times that the power increases and then decreases.
Down/Up	This choice repetitively steps down and up the TPC pattern. Use the TPC Number of Steps cell to set the number of times that the power decreases and then increases.
All Up	This choice consecutively steps up the TPC pattern.
All Down	This choice consecutively steps down the TPC pattern.

When you click the cell, a dialog box button ( ) appears and provides access to Data Source Selection dialog box where you select the data type. This cell is available only when DCH is the DPCH data selection, or, when FACH or PCH is the S-CCPCH data selection.

Block Size

Range: 1 to 50000

Default: 244

Sets the coupling block size for the selected dedicated transport channel DCH/FACH/PCH. This cell is available only when DCH is the DPCH data selection, or, when FACH or PCH is the S-CCPCH data selection.

Coding Type

Choices: 1/2 rate convolutional encoder | 1/3 rate convolutional encoder | turbo coder | no coding

Default: 1/3 rate convolutional encoder

Double-click or use the drop-down menu to set the DCH/FACH/PCH coding type. This cell is available only when DCH is the DPCH data selection, or, when FACH or PCH is the S-CCPCH data selection.

CRC

Choices: 0 | 8 | 12 | 16 | 24

Default: 16

Double-click or use the drop-down menu to set the DCH/FACH/PCH cyclic redundancy bits. This cell is available only when DCH is the DPCH data selection, or, when FACH or PCH is the S-CCPCH data selection.

Number of Blocks

Range: 1 to 512

Default: 1

Sets the DCH/FACH/PCH Number of Blocks. This cell is available when DCH is the DPCH data selection, or, when FACH or PCH is the S-CCPCH data selection.

Rate Matching Attribute

Range: 1 to 256

Default: 256

On the DPCH, enter a DCH rate matching attribute. This cell is available only when DCH is the DPCH data selection.

On the S-CCPCH, enter a FACH or PCH rate matching attribute. This cell is available only when FACH/PCH is the S-CCPCH data selection.

TTI

Choices: 10 ms | 20 ms | 40 ms | 80 ms

Default: 40 ms

Double click or use the pull-down menu to set the TTI for the selected channel. This cell is available only when DCH is the DPCH data selection.

S-CCPCH Transport Channel

The Transport Channel settings are available only after selecting FACH/PCH as the S-CCPCH Data type. To add or remove FACH/PCH, use the Number of FACH/PCH cell.

TFCI Field, TFCI, Pilot Bits are determined by Slot Format. The coupling rule is defined in Table 18 in TS 25.211.

When the Ntfci in Table18 (TS 25.211) is 0, TFCI is grayed out and TFCI Field is set to Off. When the Ntfci is not 0, TFCI is valid to set and TFCI Field is set to On.

When the Slot Format value is less than 8, the TFCI Field is read only. When the Slot Format value is more than 7, the TFCI Field is valid to set, if it is turn off, DTX shall be used in TFCI field. Only the S-CCPCH with QPSK is supported.

If the puncture rate of a transport channel with turbo coding exceeds 2/3, an error message is shown on the status bar.
