E4438C-419 Signal Studio for 3GPP W-CDMA HSPA Technical Overview

E4438C-419 Signal Studio for 3GPP W-CDMA HSPA Technical Overview General capabilities What is High Speed Packet Access (HSPA)? Create 3GPP Release 99 W-CDMA channels with HSPA channels The Third Generation Partnership Project (3GPP) release 5 and 6 extend the existing W- CDMA specifications with high speed downlink packet access (HSDPA) and high speed uplink packet access (HSUPA). The combination of HSDPA and HSUPA is known simply as high speed packet access (HSPA). HSPA provides improvements in downlink efficiency with peak data rates of 384 kbps to 14.4Mbps, and in uplink efficiency with peak data rates of 384 kbps to 5.76Mbps, higher capacity, reduced latency, and improved coverage.

About HSDPA High speed downlink packet access (HSDPA) is a digital packet-based service in the 3GPP W- CDMA radio format, introduced in release 5 of the 3GPP specifications. HSDPA which employs adaptive modulation and coding to continually reconfigure the downlink, optimizing data throughput for each user depending on the instantaneous quality of the link, and is expected to provide higher data throughput (up to 14.4 Mbps in the W-CDMA downlink). R99 W-CDMA uses QPSK modulation, while HSDPA can utilize 16QAM when the link quality permits and supports up to 15 multicodes. The basic downlink channel configuration consists of one or more HS-PDSCHs, along with an associated DPCH combined with a number of separate shared physical control channels (HS- SCCH). The group of HS-SCCHs allocated to the UE at a given time is called an HS-SCCH set, and more than one set can be used in one given cell. The UE is provided one HS-SCCH set per HS-PDSCH configuration. HSDPA also includes an uplink channel, the HS-DPCCH, that provides critical feedback information from the UE to the BTS, such as the channel quality indicator (CQI) and ACK/NACK data. High-speed data is transmitted on the HS-DSCH, while the associated signaling information is transmitted by the HS-SCCH. There can be a maximum of four HS-SCCH channels. For each HS-DSCH transmission time interval (TTI) each HS-SCCH carries the HS-DSCH related downlink signal information for one UE. The signal information on the HS-SCCH includes: Channelization-code set information Modulation scheme information Transport-block size information Hybrid-ARQ process information Redundancy and constellation version New data indicator UE identity 2

HSDPA control channel structure The following figure shows the overall control channel structure for HSDPA.. Figure 1. HSDPA control channel structure 3

About HSUPA HSUPA (high speed uplink packet access) is a digital packet based service in the 3GPP W- CDMA radio format introduced in release 6 of the 3GPP specifications. HSUPA is expected to provide higher data throughput (up to 5.76 Mbps in the W-CDMA uplink) through the use of numerous spreading factor combinations. Several new physical channels are added to provide and support high-speed data transmission for the Enhanced Data Channel (E-DCH). As shown in the figure below, two new codemultiplexed uplink channels are added: E-DCH Dedicated Physical Channel (E-DPDCH) E-DCH Dedicated Control Channel (E-DPCCH) Similarly, three new channels are added to the downlink: E-DCH HARQ Acknowledgement Indicator Channel (E-HICH) E-DCH Absolute Grant Channel (E-AGCH) E-DCH Relative Grant Channel (E-RGCH) The E-DCH subframes can be either 2 ms or 10 ms in length. The corresponding E-DPDCH carries the payload data, and the E-DPCCH carries the control data which consists of the E-TFCI, RSN and Happy bit. In the downlink, the E-HICH carries the HARQ protocol for the corresponding E-DPDCH, while the E-AGCH provides an absolute limitation of the maximum amount of uplink resources the UE may use. The E-RGCH controls the resource limitations by increasing or decreasing the limitations with respect to the previous value. 4

General Capabilities Set up channel parameters with ease Signal Studio for 3GPP W-CDMA HSPA provides a flexible, intuitive graphical user interface that is easy and straightforward to use. The tree view allows you to quickly navigate to the through the software to the desired location where all of the channel parameters are set in just a few windows. Each downlink and uplink channel can be configured differently including data type, power levels, spreading code, and more. For example, a sophisticated, complex CQI pattern up to 1280 subframes in length, can be easily created for testing the BTS response to different mobile scenarios. The graphical displays makes it easy to confirm the parameters you ve chosen, while the software provides feedback on your settings, enabling you to quickly resolve any conflicts. Figure 3. The graphical user interface simplifies configuration of sophisticated test signals such as HARQ and AMC. 6

Quickly verify signal configuration Code domain plots are automatically generated for the configured channel setup and show the distribution of signal power across the set of code channels. Now you can visually check for code channel power levels and code domain conflicts prior to sending the test signal to the DUT, without the need for a vector signal analyzer. Figure 4. View code domain plots and power settings for all configured channels. Save time using preconfigured setups The Signal Studio user interface provides quick setups for both downlink and uplink channels as specified in the 3GPP standards, enabling you to start generating standards-based signals right away for BTS and MS performance testing using the following convenient, quick setups: RMC, FRC, and Beta power level settings. Each standard-compliant quick setup is characterized by preset parameters that can be modified, saved, and then recalled when needed to generate a library of different test scenarios tailored to meet your specific testing requirements. Create W-CDMA and HSPA channels simultaneously The W-CDMA channels introduced in release 5 can be generated simultaneously with the HSPA channels from release 5 and release 6 to aid in synchronizing the E4438C with your device under test. Once synchronization is established, the full suite of W-CDMA and HSPA channels enables testing under real-world conditions. Additionally, the W-CDMA channels can be used independently, enabling testing of release 99 W-CDMA functionality. 7

Generate transport and physical layer coding for W-CDMA and HSPA channels Signal Studio for 3GPP W-CDMA HSPA simplifies creating HSPA waveforms for use with the E4438C ESG vector signal generator. The software provides convenient access to transport and physical layer parameters to enable the generation of W-CDMA based HSPA test signals specifically designed for receiver bit error rate (BER) and block error rate (BLER) analysis. Add calibrated AWGN The AWGN functionality adds noise to the W-CDMA signal which simulates the interference caused by other transmitters (other cellular communications, TV stations, radio stations) in the vicinity of the cell area. Precisely adjust the noise power with digital accuracy by setting C/N directly from the user interface. This enables sensitivity testing of receivers to be made along with 3GPP functional tests. Automate your test plan with SCPI The full complement of SCPI commands included in the Option 419 software enable you to configure the W-CDMA, HSDPA, and HSUPA downlink and uplink channel parameters and remotely control the signal generator parameters for waveform generation to automate your test process. The SCPI commands needed to replicate the current configuration created with the user interface can be saved at any time to a text file for use in automating signal generation with your test executive. This file includes not only the W-CDMA signal configuration, but also the signal generator settings, such as frequency and amplitude. This can save hours of time by not requiring a manual search for the correct SCPI commands. 8

HSDPA Capabilities Perform BLER Analysis Signal Studio for 3GPP W-CDMA HSPA provides test signals ideal for performing receiver BLER measurements on the HS-PDSCH channel with a transport channel layer coded signal. To isolate different receiver subsections during testing, the data payload can be either physical layer coded only, or physical and transport layer coded. The transport layer adds CRC bits, code block segmentation, turbo encoding, rate matching, interleaving, and constellation rearrangement before the data is sent to the physical layer. The CRC bits are calculated in real-time for each transmitted packet enabling BLER testing to be performed. The physical layer spreads and scrambles the data and then maps it to one or more QPSK or 16QAM constellations. Figure 5. Easily configure transport layer parameters to perform BLER testing 9

Customize HARQ Response The Hybrid Automatic Repeat Request (HARQ) feature in the 3GPP standard provides a way for the mobile handset to provide feedback on whether or not a particular transmission was received. Signal Studio for 3GPP W-CDMA HSPA enables testing of this advanced 3GPP feature. A list of simulated ACK/NACK responses from the mobile handset can be configured that determine how the downlink packets are transmitted, simulating closed loop testing of HARQ functionality. For example, if a NACK signal is received, the next packet will be retransmitted according to how the Incremental Redundancy (IR) parameters are configured. This type of testing is essential for evaluating the mobile receiver's ability to assemble the correct data from the various received packets. Adaptive Modulation Coding Adaptive modulation coding (AMC) provides the flexibility to match the modulation coding scheme to the average channel conditions for each user. The UE reports the channel conditions to the BTS via the uplink channel CQI field in the HS-DPCCH. Each CQI value corresponds to a certain transport block size, number of HS-PDSCHs, modulation format, reference power adjustment, virtual IR buffer size, and RV parameter for a certain UE category as described in 3GPP TS 25.214. A list of simulated CQI responses from the mobile handset can be configured that determine the type of modulation and coding that will be used in subsequent transmissions. This type of testing is essential for evaluating the mobile receiver's ability to demodulate packets with different modulation and different coding parameters. Figure 6. Easily set up HARQ and AMC parameters from one window in the software's user interface. 10

Selectable QPSK or 16QAM Modulation Signal Studio for 3GPP W-CDMA HSPA allows you to easily choose between QPSK or 16QAM to test the UE's ability to correctly demodulate either format. The high speed physical data shared channel (HS-PDSCH) is modulated, spread, scrambled, and summed as are other W-CDMA downlink physical channels, the difference being R99 W-CDMA uses QPSK only and that HSDPA may use either standard QPSK modulation or 16QAM modulation. The spreading factor is always fixed at 16 (SF=16). The channel bit rate can vary between 480 kbps or 960 kbps based on its modulation scheme. The channel bit rate corresponds to the data rate after coding is applied. The 16QAM modulation technique is preferred when radio conditions are favorable, but based on the channel quality will automatically change to QPSK when radio conditions dictate. The software allows you to dynamically change the modulation type using the AMC functionality. This means the ability to choose between QPSK and 16QAM modulation provides real-world scenarios when testing your UE. Generate up to 15 Multicodes Signal Studio for 3GPP W-CDMA HSPA allows you to configure up to 15 multicodes to test the UE's ability to correctly demodulate multicode signals. Each HS-PDSCH is assigned one of fifteen channel code numbers from the set of channelization codes reserved for an HS-DSCH transmission. Because HSDPA technology allows multi-code transmission, a UE may be assigned multiple channelization codes (multiple HS-PDSCHs) in the same HS-PDSCH subframe, to the extent of the UE s capability. In conjunction with 16QAM modulation, you can test the UE's resource capacity for handling large amounts of data. Figure 7. Easily configure the number of HS-PDSCH multicodes 11

Configure Open Loop Transmit Diversity Evaluate receiver performance with open loop transmit diversity. Transmit diversity is a technique used to counter the effects of fading by transmitting an altered version of the W-CDMA signal through a second antenna. A single ESG can generate a transport layer coded signal simulating antenna 1 or antenna 2. Two ESGs can be synchronized together to simultaneously generate the antenna 1 and antenna 2 signals. The user equipment (UE) must be able to recognize that the information is coming from two different locations and properly decode the data. The primary and secondary synchronization channels employ transmit switched time diversity (TSTD) while all other channels use space time transmit diversity (STTD). The TSTD encoding can be turned off to facilitate signal acquisition when only one ESG is used. STTD encoding is used on the following channels: P-CCPCH PICH DPCH HS-PDSCH HS-SCCH OCNS E-AGCH E-RGCH E-HICH Figure 8. Open loop transmit diversity connection diagram 12

HSUPA Capabilities Perform BER Analysis Signal Studio for 3GPP W-CDMA HSPA provides test signals ideal for performing receiver BER measurements on HSUPA channels using continuous PN sequences on the physical layer payload data. To isolate different receiver subsections during testing, the payload data can be either physical layer coded only, or physical and transport layer coded. The transport layer automatically adds CRC bits, code block segmentation, turbo encoding, rate matching, interleaving, and constellation rearrangement before the data is sent to the physical layer. The CRC bits are calculated in real-time for each transmitted packet also enabling BLER testing to be performed. The physical layer spreads and scrambles the data and then maps it to one or more I or Q coded channels. Figure 9. Easily configure coding data for HSUPA channels. Validate Physical Layer Performance Signal Studio for 3GPP W-CDMA HSPA supports continuous PN9 assignment to individual E- DPDCHs. Since the PN9 data continues at each E-DPDCH, the spreading and scrambling operation can be checked separately for each E-DPDCH, thus allowing physical channel performance verification to be checked separately from transport layer verification. You can also use continuous PN9 assignment to verify raw E-DPDCH BER measurement. Figure 10. Assign continuous PN9 sequences to individual E-DPDCHs. 13

HARQ Testing with Scenario-based or Real-time Configurations Simulate real world conditions Simulate the ACK/NACK feedback process sent by the E-HICH (E-DCH Hybrid ARQ Indicator Channel) in a real system by using scenario-based or real-time feedback signals from the BTS. The software provides several methods for specifying the ACK/NACK pattern. In the ACK/NACK Pattern data entry window, select an all ACK pattern, create your own pattern, import a custom user pattern from a previously saved file, or input an external real-time TTL signal through a BNC connector on the rear panel of the signal generator. Test receiver functionality with multiple HARQ scenarios Easily set up diverse HARQ patterns to test the BTS response to different mobile scenarios. Throughput testing can be performed on the BTS receiver using closed loop testing with a realtime feedback TTL signal, which emulates the ACK/NACK sequence dynamically changing the packet data coding to be sent to the BTS. Supported HARQ functionality HARQ TX, DTX, or user-defined pattern None, IR, or CC retransmission scheme choices RSN controlled by ACK/NACK RV index controlled by RSN value with IR Up to 15 re-transmissions Figure 11. Easily set up HARQ parameters from one window in the software's user interface. Test throughput using HARQ incremental redundancy Quickly test your system in early or final design stages for throughput performance using HARQ incremental redundancy. The software correctly implements how HARQ controls the retransmission of packet data based on the ACK/NACK pattern. When the RSN reaches three, it remains there until the specified number of transmissions has occurred. The redundancy version index automatically changes the linking with RSN parameter at E-DCH HARQ rate matching stage as specified in TS 25.212 V6.70.

Compressed Mode Compressed mode operation creates discontinuous transmission (DTX) slots (idle periods) in the radio frames so that the UE can perform interfrequency measurements. The receiver must be able to recognize these DTX gaps and continue to demodulate and decode the data correctly. The software generates uplink transport layer coded compressed frames according to the 3GPP standard. Implemented on both HSUPA and R99 W-CDMA channels Supports DPCH compression mode SF/2 method Figure 12. Compressed mode pattern parameters 15

Quick Setup for Transmit Test Beta Values Quickly generate 3GPP standard mobile station transmitter tests by selecting one of the preconfigured subtests. Each of the quick setups is characterized by preset parameters that can be modified to meet your specific testing requirements. The tables below highlight the Release 6 Beta factors for transmitter tests from TS 34.121 table C.10.1.4 (Subtest 1-6) and Release 7 Beta factors from TS 34.121 table C.11.1.3 (Subtest 1-5).

For all other combinations of DPDCH, DPCCH, HS-DPCCH, E-DPDCH and E-DPCCH the MPR is based on the relative CM difference. 3. For subtest 1 the β c /β d ratio of 11/15 for the TFC during the measurement period (TF1, TF0) is achieved by setting the signalled gain factors for the reference TFC (TF1, TF1) to β c = 10/15 and β d = 15/15. 4. For subtest 5 the β c /β d ratio of 15/15 for the TFC during the measurement period (TF1, TF0) is achieved by setting the signalled gain factors for the reference TFC (TF1, TF1) to β c = 14/15 and β d = 15/15. 5. In case of testing by UE using E-DPDCH Physical Layer category 1, Sub-test 3 is omitted according to TS25.306 Table 5.1g. 6. β ed can not be set directly, it is set by Absolute Grant Value 16

Transmit Power Control (Uplink) The 3GPP standard implements real-time power control between the mobile handset and the base transceiver station. The mobile handset measures the received power from the base transceiver station and provides Transmit Power Control (TPC) feedback which increases or decreases the power level. In the Signal Studio software, the TPC bits can be set using simple predefined patterns, custom patterns from a user file, or in real time through the use of an external trigger signal. Selectable parameters include setting the power step size to 0.5 db, 1.0 db, 2.0 db, or 3.0 db and setting initial power, minimum power, and maximum power. Testing the TPC functionality is important for determining if the base transceiver station can correctly decode the TPC bits and then set its power to the correct level. Figure 13 shows an example of transmit power control using an external trigger and a user-defined bit sequence. Figure 13. Example of external trigger and user file for uplink transmit power control 17

Verify Baseband Performance Set up diverse E-TFC coding patterns for BTS baseband verification. Select main or alternate values for the E-TFC table and index, E-DPDCH power, spreading factor, number of E-DPDCHs, and E-DCH data to test E-TFC functionality. Assign these main or alternate values in the easy-touse data type entry window. Create your own pattern, use a custom user pattern from a previously saved file, or input an external real-time TTL signal through a BNC connector on the rear panel of the signal generator. View your selected pattern in the graphical display. Figure 14. Quickly assign main or alternate parameters to test E-TFC functionality in the pattern set up window. 18
