Getting Started

The RSA3303B, RSA3308B, and RSA3408B Option 40 3GPP Release 6 (HSUPA) analysis software enables modulation analysis of HSUPA (High Speed

Uplink Packet Access) signals defined in 3GPP (3

Generation Partnership Project) Release 6 (“3GPP-R6”). Measurements can be performed on downlink QPSK and 16QAM or uplink BPSK signals.

Uplink Analysis

Measurement Process.

The following steps show the internal process for the

3GPP-R6 downlink analysis:

1. Perform flatness correction and filtering.

2. Establish the synchronization with P-SCH.

3. Determine the range of scrambling code numbers with S-SCH.

4. Fix the scrambling code number and the phase.

5. Correct the frequency and the phase.

6. Perform high-speed Hadamard transformation.

7. Calculate the power for each symbol on all channels.

The analyzer supports the following types of 3GPP-R6 uplink signals:

 DPCCH (Dedicated Physical Control Channel)

 DPDCH (Dedicated Physical Data Channel)

 HS-DPCCH (Dedicated Physical Control Channel for HS-DSCH

(High Speed Downlink Shared Channel)

 E-DPCCH (Enhanced Dedicated Physical Control Channel)

The analyzer has the following measurement functions:

ACK/NACK/PRE/POST indicator, DTX (Discontinuous Transmission), and CQI (Channel Quality Indicator).

 E-DPCCH analysis: Measures the E-DPCCH to detect and display the E-TFC

(E-DCH Transport Format Combination) indicator, RSN (Retransmission Sequence Number), and Happy.

 Code domain power: Measures the power relative to the total power for each

channel. Multi-rate is supported and up to 512 channels can be measured.

 Power codogram: Measures the code domain power continuously for up to

150 slots (0.1 sec) and displays spectrogram for each slot.

NOTE.

The code domain power and the power codogram can be displayed in the

subview only.

Measurement Process.

The following steps show the internal process for the

3GPP-R6 uplink analysis:

1. Perform flatness correction and filtering.

2. Search for a synchronous point by de-spreading DPCCH.

3. Correct the frequency and phase.

4. Obtain symbols for each channel of DPDCH and DPCCH, and calculate power

for each symbol.

NOTE.

using the frequency and phase to establish synchronization. If the level of DPCCH or the control part is much lower than (about 1/10

The analyzer despreads DPCCH and the control part of an input signal,

) the level of the other channels

(DPDCH or the data part), the analysis may not be performed accurately.

Suppose that one block contains M frames; the acquisition length is calculated with this equation:

(One block acquisition length) = M × (One frame acquisition length)

One frame acquisition length is determined by span and indicated on the Spectrum Length side key.

The number of frames M required for measuring N slots must meet the following condition:

M > K × (N + 1.2) + 1

where K = 16.7 (for the span of 20 MHz and 15 MHz)

8.34 (for the span of 10 MHz)

Measurement Procedure

The following procedure shows you how to acquire data from multiple slots in advance, measure continuous data, and obtain continuous code domain power:

NOTE.

For details on setting frequency, span, and amplitude, refer to your

instrument user manual.

1. Press the Demod key on the front panel.

2. Press the side key Standard... →3GPP-R6-UL.

3. Press the Frequency/Channel key on the front panel to set frequency.

If you use the channel table, do these steps:

 Press the Channel Table... side key and select W-CDMA-UL.

 Press the Channel side key and select a channel by rotating the general

purpose knob.

The center frequency is set to the value corresponding to the channel.

4. Press the Span key on the front panel to set the span.

5. Press the Amplitude key on the front panel to set the amplitude appropriately.

NOTE.

If the input level is too high, “Overrange-increase RefLev or Atten” displays in the red box at the center top of the screen. If this occurs, raise the reference level.

6. Press the Acquisition/Analysis key on the front panel and then the

Acquisition Length side key to set the time length to acquire one block.

2-30

Suppose that one block contains M frames; the acquisition length is calculated with this equation:

(One block acquisition length) = M × (One frame acquisition length)

One frame acquisition length is determined by span and indicated on the Spectrum Length side key.

The number of frames M required for measuring N slots must meet the following condition:

M > K × (N + 1.2) + 1

where K =16.7 (for span 20 MHz and 15 MHz)

8.34 (for span 10 MHz)

4.17 (for span 5 MHz)

Display Method for HS-DPCCH

The measurement results for each channel are normally displayed in the view for each time slot. But HS-DPCCH has the different display methods for the settings of Subframe Offset Select in the Meas Setup menu. This section describes how to display HS-DPCCH in each view.

Code Domain Power, Power Codogram, and Code Power versus Time Slot

 When Subframe Offset Select is set to AUTO

Each time slot is displayed without offset as the other channels (see the upper part of Figure 2-17).

 When Subframe Offset Select is set to STO (Subframe to Time slot Offset)

Each time slot is displayed with offset specified by Subframe to TS Offset in the Meas Setup menu. Also in the total power calculation for the relative value display, only HS-DPCCH is offset in the same way. But the last time slot is displayed without offset (see the lower part of Figure 2-17).

 When Subframe Offset Select is set to DTO (Downlink Time Offset)

Each time slot is displayed in the same manner as when Subframe Offset Select is set to STO. But the number of offset symbols is determined by this formula: [151 − (Downlink Time Offset)] mod 10 (see the lower part of Figure 2-17).
