HSDPA RB Test Mode Setup

HSDPA Pattern Parameters

• Transmission Mode

  This setting allows you to activate some specific transmission pattern on the HSDPA channel. The transmission pattern consists of two segments which are transmitted periodically. You can set the length or type of each segment. The transmission pattern is defined by Initial SFN , Initial Subframe , First Segment Length , First Segment Type , Second Segment Length and Second Segment Type .

  To apply the transmission pattern, you must set up an RB test mode connection and set the RB Test HS-DSCH Configuration Type to User Defined . Besides, it is strongly recommended you set User Defined Inter-TTI Interval to 1 and User Defined Number of HARQ Processes to 6 (or more than 6), respectively.

  Once the transmission pattern is applied, the transmission will not take into account the compressed mode gap or the CPC DRX reception gap. In other words, an HSDPA block will be transmitted in the TTI indicated to be "transmission" pattern even this TTI is a compressed mode transmission gap or CPC DRX reception gap.

  This setting can be changed only when the Call Status is Idle or Connected .

  GPIB Command: CALL:HSDPa:SERVice:RBTest:UDEFined:TMODe

• Initial SFN

  This setting, together with Initial Subframe , determines the TTI when to start the transmission pattern.

  This setting can not be changed when the Transmission Mode is set to Pattern .

  GPIB Command: CALL:HSDPa:SERVice:RBTest:UDEFined:PATTern:INITial:SFNumber

• Initial Subframe

  This setting, together with Initial SFN , determines the TTI when to start the transmission pattern.

  This setting can not be changed when the Transmission Mode is set to Pattern .

  GPIB Command: CALL:HSDPa:SERVice:RBTest:UDEFined:PATTern:INITial:SUBFrame

• First Segment Length

  First Segment Length defines the length of the first segment (in HSDPA TTI (2ms)).

  This setting can not be changed when the Transmission Mode is set to Pattern .

  GPIB Command: CALL:HSDPa:SERVice:RBTest:UDEFined:PATTern:SEGMent[1]:LENGth

• First Segment Type

  If the First Segment Type is set to Transmit , the test set transmits the HSDPA blocks during the first segment. If the First Segment Type is set to DTX , the test set uses alternative H-RNTI to transmit HSDPA blocks which means DTX for the UE.

  This setting can not be changed when the Transmission Mode is set to Pattern .

  GPIB Command: CALL:HSDPa:SERVice:RBTest:UDEFined:PATTern:SEGMent[1]:TYPE

• Second Segment Length

  Second Segment Length defines the length of the second segment (in HSDPA TTI (2ms)).

  This setting can not be changed when the Transmission Mode is set to Pattern .

  GPIB Command: CALL:HSDPa:SERVice:RBTest:UDEFined:PATTern:SEGMent2:LENGth

• Second Segment Type

  If the Second Segment Type is set to Transmit , the test set transmits the HSDPA blocks during the second segment. If the Second Segment Type is set to DTX , the test set uses alternative H-RNTI to transmit HSDPA blocks which means DTX for the UE.

  This setting can not be changed when the Transmission Mode is set to Pattern .

  GPIB Command: CALL:HSDPa:SERVice:RBTest:UDEFined:PATTern:SEGMent2:TYPE

Serving Cell Parms

When RB Test User Defined DC-HSDPA State is set to On , the following parameters are grouped as the serving cell paramerters:

• User Defined 64QAM State
• User Defined MAC-ehs HS-DSCH TB Size Table
• User Defined Number of Active HS-PDSCHs
• User Defined Explicit UE IR Buffer Size
• User Defined Modulation Type
• User Defined Inter-TTI Interval

Secondary Cell Parms

When RB Test User Defined DC-HSDPA State is set to On , the following parameters are available as the secondary serving cell paramerters:

• RB Test User Def Secondary Cell 64QAM State
