Downlink Channel Codes and Levels

Last updated: October 19, 2012

You can specify the channel code, state and level of most of the downlink channels generated by the test set (some are fixed). Some of the downlink channels can have a different code, state or level depending upon the state of the test set.

Downlink Channel Codes and Levels for each Test Set State
Operating Mode	Call State	Connection Type	Codes	State/Levels
FDD Test			FDD Test Operating Mode
Active Cell	Idle		Shared DL Channel Codes	Downlink Channel Levels
	Connected	non-HSDPA/ non-HSPA	Shared DL Channel Codes , WCDMA DL Channel Codes	WCDMA Connected DL Channel Levels
	Connected	HSDPA	Shared DL Channel Codes , HSDPA/HSPA DL Channel Codes	HSDPA Connected DL Channel Levels
	Connected	HSPA	Shared DL Channel Codes , HSDPA/HSPA DL Channel Codes	HSPA Connected DL Channel Levels

Use the Downlink Channel Code Preset to easily configure the 3GPP TS 34.121-1 channel codes from the front panel.

If the sum of the downlink channel levels is less than the cell power setting, Orthogonal Channel Noise Simulator (OCNS) power is automatically added.

Downlink Channel Codes

Downlink Channel Codes can not be changed inActive Cell operating mode (useCell Off operating mode to change the active cell downlink channel codes). The downlink channel codes currently in use are displayed in the Downlink Code Channel Information window.

HSDPA/HSPA DL Channel Codes

This section is only applicable to the lab application or feature-licensed test application.

The method for setting downlink DPCH channel codes used during HSDPA and HSPA connections differs between the test application and lab application. The following table illustrates the valid channelization codes for each type of DPCH channel used during HSDPA and HSPA connections, and indicates the GPIB commands and front panel fields used to set the channelization codes, for both the test application and lab application (see How Do I Change Generator Information? to help you find these fields from the front panel).

You can also set the channel code for the following downlink HSDPA and HSPA channels:

Antenna 2 S-CPICH Channelization Code
This setting controls the channelization code of the S-CPICH, which has a spreading factor of 256.

GPIB command: CALL[:CELL[1]]:CPIChannel:SECondary:CCODe:CODE
E-AGCH Channelization Code
This setting controls the channelization code of the E-AGCH. The E-AGCH has a spreading factor of 256.

GPIB command: CALL[:CELL]:EAGChannel:CCODe:CODE
E-HICH/E-RGCH Channelization Code
This setting controls the channelization code of the E-HICH and E-RGCH. These channels have a spreading factor of 128 and by definition use the same channelization code (see 3GPP TS 25.213 s5.2.1). 40 bit signatures are used to provide orthogonality between the two channels (see HSPA Downlink Channel Details ).

GPIB command: CALL[:CELL]:EHIChannel:CCODe:CODE
PS Data First HS-PDSCH Channel Code
This parameter sets the channelization code of the first HS-PDSCH when on an HSDPA packet data connection. If more than one HS-PDSCH is being generated, the other HS-PDSCHs are assigned to the subsequent channelization codes.

This parameter cannot be set to 5 or 6 when S-CCPCH Channelization Code is set to 26. Also, the number of HS-PDSCHs specified by the PS Data HS-DSCH Configuration Type , when added to thePS Data First HS-PDSCH Channel Code cannot exceed 15 (otherwise the HS-PDSCHs would collide with the downlink OCNS channels).

GPIB command: CALL:HSDPa:SERVice:PSData:HSPDschannel:CCODe:CODE
RB Test Mode First HS-PDSCH Channel Code
This parameter sets the channelization code of the first HS-PDSCH when on an HSDPA RB Test Mode connection. If more than one HS-PDSCH is being generated, the other HS-PDSCHs are assigned to the subsequent channelization codes.

This parameter cannot be set to 5 or 6 when S-CCPCH Channelization Code is set to 26. This parameter cannot be set to 5 whenHSDPA DPCH 12.2k RMC Channelization Code is set to 45 or 54, and cannot be set to 6 whenHSDPA DPCH 12.2k RMC Channelization Code is set to 54. Also, the number of HS-PDSCHs specified by the FRC Type or User Defined Number of Active HS-PDSCHs settings, when added to theRB Test Mode First HS-PDSCH Channel Code cannot exceed 16 (otherwise the HS-PDSCHs would collide with the downlink OCNS channels).

Downlink Channel Code Preset

The downlink channel code preset (front panel: DL Chan Code Preset Configs ) allows you to configure the test set for 3GPP TS 34.121-1 channel code much easier (the DL Channel Code Preset Configurations are only available from the front panel; there are no GPIB commands to configure these presets).

The Operating Mode must be set to Cell Off before selecting one of the DL channel code preset configurations.

DL Channel Code Preset Configurations from 3GPP TS 34.121-1 (These presets configure the test set as defined in 3GPP TS 34.121-1 for non-HSDPA, HSDPA with 10 HS-PDSCHs, HSDPA with 15 HS-PDSCHs, and E-DCH with 5 HS-PDSCHs.)
DL Channel Code Preset Configuration for Compressed Mode (This preset configures the test set for use with compressed mode on a DL 384 kbps channel. See Channel Type for supported DL 384 kbps channels.)

Downlink Channel Levels

The relative level of all downlink channels can be individually set or turned off (except that the P-CCPCH and the SCH are time multiplexed, and use the same level for both channels). The level of each active channel is a fraction of the Cell Power (Îor) setting, expressed in dB. If the summed level of all channels is less than one, the orthogonal coded noise source (OCNS) is turned on to account for the difference (see Orthogonal Channel Noise Simulator (OCNS) ).

The downlink code channel levels currently in use (as well as the "desired" levels) are displayed in the Downlink Code Channel Information screen.

The downlink channel levels for idle mode (no DPCH is present) may be different than the levels used during a call (DPCH is present). Thus, there are two different level settings for the downlink channels in active cell operating mode: Downlink Channel Levels and Connected DL Channel Levels .

Considerations When Setting Code Channel States and Levels

All code channels can be set between 0 and -20 dB, except the relative power level of the DPCH channel which can be set from 0 to -30 dB.
Any code channel powers that areOn must not be greater than 30 dB below the Total RF Power .
The sum of the relative levels of the code channels cannot be greater than 100% of the cell power.
If you set a code channel state toOff , the test set will not automatically turn it back on if it is needed to perform a call processing operation you've requested (for example, if you turnPICH Level toOff , theOriginate Call procedure will fail).

Downlink Channel Levels

The Downlink Channel Levels set of power levels is used when RRC State isIdle orCELL_FACH .

These levels cannot be changed in theActive Cell operating mode. You can query these settings via GPIB and view them on the front panel duringActive Cell mode operation, but attempting to change the levels duringActive Cell mode operation results in an error message (use theCell Off operating mode to change the active cell downlink channel levels).

GPIB command: CALL[:CELL]:PICHannel[:SLEVel]
AICH Level
GPIB command: CALL:AICHannel
DPCH Level
Note: no DPCH is generated before the call is established. Setting DPCH Level to a non-zero value simply adds that power to the OCNS.

GPIB command: CALL:DPCHannel[:SLEVel]

Connected DL Channel Levels

The Connected DL Channel Levels are used when RRC State isCELL_DCH . These levels are applied after the RRC Connection Setup message is sent by the test set during the RRC Connection Setup Procedure , directing the UE to go intoCELL_DCH (i.e. once a DPCH has been established). When the DPCH channel is released, the test set transitions back to the Downlink Channel Levels set.

These levels can be changed in any operating mode, includingActive Cell . This allows you to vary the relative channel levels while a call is connected in order to test the UE's response.

These settings specify the connected downlink channel levels relative to Cell Power (Îor).

Orthogonal Channel Noise Simulator (OCNS)

OCNS is used to simulate additional users on the downlink. OCNS is automatically enabled when the sum of the levels of all the enabled downlink physical channels is less than the cell power setting.

Cell 1 OCNS is made up of the following 16 separate code channels: 2, 11, 17, 23, 31, 38, 47, 55, 62, 69, 78, 85, 94, 113, 119, and 125, with an OVSF of 128. The fraction of the composite OCNS power that is allocated to each of the code channels making up the composite OCNS are as specified by 3GPP TS 34.121 sE.3.6.

Cell 2 OCNS ( lab application only ) consists of a single channel at OVSF 128,2.

As individual downlink channel levels are adjusted, the composite OCNS level is automatically set to a value equal to the difference between the summed downlink channel levels and the cell power setting (when the sum of the downlink code channel levels is such that the composite OCNS is less than -30 dB, it is set toOff ).

The OCNS currently in use (as well as the "desired" level) is displayed in the Downlink Code Channel Information window.

GPIB command: CALL:OCNSource (query only)

OCNS in HSDPA/HSPA

This section is only applicable to the lab application or feature-licensed test application.

When HSDPA or HSPA is active (see HSDPA Activation in FDD Test and HSDPA Activation in Active Cell ), the cell 1 OCNS is made up of the following 7 separate code channels: 122, 123, 124, 125, 126, and 127, with an OVSF of 128, rather than the code channels described in Orthogonal Channel Noise Simulator (OCNS) above. The fraction of the composite OCNS power that is allocated to each of the code channels making up the composite OCNS are as specified by 3GPP TS 34.121 sE.5.2.

Antenna 2 S-CPICH Configuration

The parameter specifies whether S-CPICH is transmitted on antenna 2 when Current MIMO Configuration Status is set to Active in Active Cell/FDD Test Operating Mode. If Antenna 2 S-CPICH Configuration is set to On , S-CPICH will be transmitted on antenna 2 and its scrambling code will be Serving Cell Primary Scrambling Code . If Antenna 2 S-CPICH Configuration is set to Off , S-CPICH will not be transmitted on antenna 2.

If you want to change Ant2 S-CPICH Cfg to Off , ensure that:

HSDPA MIMO Antenna 2 Pilot Configuration is set to P-CPICH
Proper power level configuration of the serving cell in Active Cell/FDD Test Operating Mode
HSDPA/HSPA Antenna 2 Connected S-CPICH State is set to Off. You can change the setting via CALL:ANTenna2:CONNected:CPIChannel:SECondary:STATe:HSDPa and CALL:ANTenna2:CONNected:CPIChannel:SECondary:STATe:HSPA

This setting can only be set when the Call/Data Status is Idle .
