HSUPA Parameters

E-TFCI Recording

The test set allows you to record a sequence of E-TFCI values sent by the UE. Only E-TFCI values corresponding to blocks that pass their CRC check are recorded.

Before you Start Recording E-TFCI Values , set the E-TFCI Rec Count to the number of E-TFCI values you wish to record. You can then view the results on the E-TFCI Recording Information screen.

• E-TFCI Rec Count

  This setting controls how many E-TFCI values to record when the Start Recording E-TFCI Values action is initiated.

  GPIB command: CALL:HSUPa:ETFCi:RECord:COUNt

  This setting can only be changed when E-TFCI Recording State is idle.

• Start Recording E-TFCI Values

  This action immediately starts E-TFCI recording. You must be on an HSPA connection to record E-TFCI values. Upon successful start of E-TFCI recording, Recorded E-TFCI Values and Number of E-TFCI Results Recorded are set to their default values, and E-TFCI Recording State is set to Recording .

  GPIB command: CALL:HSUPa:ETFCi:RECord:STARt

• Stop Recording E-TFCI Values

  This action stops E-TFCI recording. E-TFCI recording is also automatically stopped if the call ends.

  GPIB command: CALL:HSUPa:ETFCi:RECord:STOP

E-RNTI Parameters

• Primary E-RNTI (Hex)

  This setting controls the primary E-RNTI that the UE is assigned when an E-DCH is configured (see 3GPP TS 25.331 s10.3.3.10a). When the test set wants to send an absolute grant to the UE, it transmits the E-AGCH using the primary E-RNTI (the Alternate E-RNTI (Hex) is used on the E-AGCH for all other frames).

  Primary E-RNTI (Hex) and Alternate E-RNTI (Hex) cannot be set to the same value.

  GPIB command: CALL:HSUPa:ERNTi[:PRIMary]

  This setting can only be changed when the connection status is idle.

• Alternate E-RNTI (Hex)

  This setting controls the alternate E-RNTI that the test set uses on the E-AGCH when it does not wish to transmit to the UE on that channel (see HSPA Downlink Channel Details for more information).

  Primary E-RNTI (Hex) and Alternate E-RNTI (Hex) cannot be set to the same value.

  GPIB command: CALL:HSUPa:ERNTi:ALTernate

  This setting can only be changed when the connection status is idle.
