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

This topic includes information on:

HSUPA Information

These results are cleared by the Clear UE Info action.

UE Reported E-DCH Category

This result contains the most recently reported E-DCH category (see 3GPP TS 25.306 s5.1 Table 5.1g) as extracted from the RRC Connection Setup Complete message.

If the UE did not report an E-DCH Category (the PhysicalChannelCapability-edchr6 information element was not present in the RRC Connection Setup Complete message) thenUnreported is returned. If the UE reports that it is not capable of E-DCH (the PhysicalChannelCapability-edch-r6 information element is present but the "unsupported" choice is indicated) thenUnsupported is returned. This result is reset toUnreported when you select Clear UE Info .

GPIB command: CALL:HSUPa:MS:REPorted:EDCHannel:CATegory?

Queued Relative Grants

This result contains the number of "Up" or "Down" relative grant commands in the relative grant queue (see Relative Grant Transmission ).

GPIB command: CALL:STATus:SGRant:RELative:QUEued:COUNt?

E-HICH Behavior

This result indicates the E-HICH Behavior setting's current value.

HSUPA Counters

TheHSUPA Information window displays counters to help you monitor the HSUPA connection status. The results are continually updated until one of the following occurs:

You press the MEASUREMENT RESET key ( SYSTem:MEASurement:RESet ).
You select Clear UE Info ( CALL:MS:REPorted:CLEar[:ALL]<[:SELected]|:WCDMa> ).
You change operating mode.
You establish a new connection in active cell operating mode (or change theChannel Type from12.2k RMC + HSPA inFDD Test Operating Mode ).
NACKs Transmitted or ACKs Transmitted reaches 150,000.

When one of these events occurs, the counters reset to zero and then resume counting.

Last Received E-TFCI
This result returns the most recently received E-TFCI value that was decoded from a non-DTX'd E-DPCCH frame. If an E-DPCCH/E-DPDCH is not active on the current call type (or ifChannel Type is not set to 12.2k RMC + HSPA inFDD Test Operating Mode ) or if an E-TFCI has not yet been successfully received since the E-DPCCH/E-DPDCH was activated, then 9.91E+37 (NAN) is returned.

This result is updated every 0.5 s.

See also E-TFCI Recording .

GPIB command: CALL:STATus:ETFCi[:LAST]?
Last Block Size
This result returns the size of the E-DCH transport block that most recently passed its CRC check and resulted in the test set transmitting an Ack on the E-HICH (note that when E-HICH Behavior is set toAll Nacks , no Acks are ever sent on the E-HICH).

This result is updated every 0.5 seconds. If a block has not been Ack'd on the E-HICH during the most recent 0.5 s, then 9.91E+37 (NAN) is returned. NAN is also returned if an E-DCH is not currently active (because a call is not active or because the current call does not utilize HSUPA).

GPIB command: CALL:STATus:EDCHannel[:CELL]:BLOCk:SIZE[:LAST]?
Avg Block Size
This result returns the average size of all the E-DCH transport blocks that passed their CRC check and resulted in the test set transmitting an Ack on the E-HICH (since the result was last reset). Note that when E-HICH Behavior is set toAll Nacks , no Acks are ever sent on the E-HICH.

This result is updated every 0.5 s and is rounded to the nearest integer number of bits (0.5 bits is rounded down).

GPIB command: CALL:STATus:EDCHannel[:CELL]:BLOCk:SIZE:AVERage?
Min Block Size
This result returns the smallest E-DCH transport block that passed its CRC check and resulted in the test set transmitting an Ack on the E-HICH (since the result was last reset). Note that when E-HICH Behavior is set toAll Nacks , no Acks are ever sent on the E-HICH.

This result is updated every 0.5 s.

GPIB command: CALL:STATus:EDCHannel[:CELL]:BLOCk:SIZE:MINimum?
Max Block Size
This result returns the largest E-DCH transport block that passed its CRC check and resulted in the test set transmitting an Ack on the E-HICH (since the result was last reset). Note that when E-HICH Behavior is set toAll Nacks , no Acks are ever sent on the E-HICH.

This result is updated every 0.5 s.

GPIB command: CALL:STATus:EDCHannel[:CELL]:BLOCk:SIZE:MAXimum?
Throughput
This result returns the average data rate received on the E-DCH since the result was last reset. The average data rate is calculated by taking the total number of bits in blocks that passed their CRC and were Ack'd on the E-HICH, divided by the time since the result was last reset. Blocks that passed their CRC but were Nack'd because E-HICH Behavior is set toAll Nacks are not counted.

This result is updated every 0.5 s.

GPIB command: CALL:STATus:EDCHannel[:CELL]:IBTHroughput?
ACKs Transmitted
This result returns the total number of Acks transmitted on the E-HICH since the result was last reset. This includes Acks transmitted for blocks with failed CRC checks when E-HICH Behavior is set toAll Acks .

This result is updated every 0.5 s.

GPIB command: CALL:STATus:EHIChannel[:CELL]:ACK[:COUNt]?
NACKs Transmitted
This result returns the total number of Nacks transmitted on the E-HICH since the result was last reset. This includes Nacks transmitted for blocks with passed CRC checks when E-HICH Behavior is set toAll Nacks .

This result is updated every 0.5 s.

GPIB command: CALL:STATus:EHIChannel[:CELL]:NACK[:COUNt]?

HSUPA Happy Bit Information

This section is only applicable to the lab application.

These results are cleared by the Clear UE Info action.

Happy Bit Delay Cond
This result returns the duration of the Happy Bit Delay Condition .

GPIB command: CALL:HSUPa:HBIT:DCONdition
Happy Bit Avg Period
This result returns the Happy Bit Averaging Period .

GPIB command: CALL:HSUPa:HBIT:APERiod
Happy Bit Ratio
The happy bit is a single bit that indicates whether the UE is happy with its current Serving Grant. The happy bit is reported on the E-DPCCH and therefore is sent each time the UE transmits a data block on the E-DCH. The definition of happy, for a UE on an HSUPA call is whether it can empty its buffers within the Happy Bit Delay Condition period using the Serving Grant. If the UE cannot empty its buffers within that time and the transmit power can be increased, then it considers itself unhappy.

This result returns the pecentage of sampled happy bits to the total number of sample results received during the most recent Happy Bit Averaging Period . For a sample to be included in this result, it must have arrived in a non-DTX'd E-DPCCH frame. If no samples are received, or a complete Happy Bit Averaging Period has not occured since the E-DCH was started, the test set will return NaN.

This value is reset to NaN when the following actions occur: a new call is started, Clear UE Info or Measurement Reset is pressed, the Operating Mode is changed, the Happy Bit Averaging Period is changed, or when the Channel Type is changed to or from 12.2k RMC + HSDPA . Clear UE Info forces the test set to start calculating a new Happy Bit Ratio result using a new Happy Bit Averaging Period .

This result is only updated at the end of a Happy Bit Averaging Period .

GPIB command: CALL:HSUPa:MS:REPorted:HBIT:RATio?
Last Happy Bit
This result returns the most recent UE reported happy bit that arrived in a non-DTX'd E-DPCCH frame.

This result is updated every 0.5 s. If no happy bit was received during the last 0.5 seconds, then the test set returns None . Possible reasons why no happy bit was received are because the UE did not transmit during this time or because an E-DCH is not active (either because the UE is not on a call or it is on a call but the E-DCH is not active).

This value is reset to None when the following actions occur: a new call is started, Clear UE Info or Measurement Reset is pressed, the Operating Mode is changed, the Happy Bit Averaging Period is changed, or when the Channel Type is changed to or from 12.2k RMC + HSDPA .

GPIB command: CALL:HSUPa:MS:REPorted:HBIT[:LAST]?

Manual Operation

To access theHSUPA Information or the HSUPA Happy Bit Information from the front panel, press Call Setup and then press the left More key until you reach theCall Control 2 of 5 menu, selectAdditional Screens ( F1 ), thenHSPA Information ( F2 ).
