14.11.1.1 DTS-1

14.11.1.1.1 Definition

The DARP reference test scenarios define a set of interfering signals and corresponding performance limits. These tests are a measure of the capability of the DARP receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of these specific unwanted modulated signals.

14.11.1.1.2 Conformance requirement

1. MS indicating support for Downlink Advanced Receiver Performance – phase I (see 3GPP TS 24.008) shall fulfil the requirements in table 2o for wanted signals on GMSK modulated channels under TU50 no FH propagation conditions and GMSK modulated interferers for the test scenarios defined in annex L. The reference performance shall be:

– For speech channels (TCH/FS) FER:  1 %

2. The values in table 2o are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
In addition for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2o at the corresponding C/I1.

3GPP TS 45.005, subclause 6.3

14.11.1.1.3 Test purpose

To verify that the MS does not exceed the first conformance requirement for TCH/FS under propagation condition TUhigh with an allowance for the statistical significance of the test.

To verify that the MS does not exceed the second conformance requirement for TCH/FS under propagation condition TUhigh with an allowance for the statistical significance of the test.

14.11.1.1.4 Method of test

14.11.1.1.4.1 Initial conditions

A call is set up according to the generic call set up procedure on a TCH/FS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.

The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal).

The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).

14.11.1.1.4.2 Procedure

a) In addition to the wanted signal, the SS produces an independent, uncorrelated interfering signal, Standard Test Signal I1 (unwanted signal).

The unwanted signal is continuous and has no fixed relationship with the bit transitions of the wanted signal. The interfering signal level is set to -80 dBm.

The fading characteristic of the wanted and the interfering signal is TUHigh.

b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.1-2 or 14.11.1-3.

c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.

d) The SS determines the number of residual bit error events for the bits of the class Ib, by examining at least the minimum number of samples of consecutive bits of class Ib. Bits are only taken from those frames not signalled as erased.

e) The SS also determines the number of residual bit error events for the bits of the class II, by examining at least the minimum number of samples of consecutive bits of class II. Bits are only taken from those frames not signalled as erased.

f) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully it is not signalled as erased.

Maximum/Minimum Duration of Test

Maximum: 10 minutes (GSM850), 10 minutes (GSM900), 10 minutes (DCS1800), 10 minutes (PCS1900).

Minimum: 4 minutes (GSM850), 4 minutes (GSM900), 2 minutes (DCS1800), 2 minutes (PCS1900).

14.11.1.1.5 Test requirements

Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.

For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7 (A7.1.3.2)

Wrong decision risk F for one single error rate test:

Fpass   =   Ffail   =   F and F   =   0.2%

Wrong decision probability D per test step:

Dpass   =   Dfail   =   D and D   =   0.0085%

Parameters for limit lines:

1. D =  0.000085 wrong decision probability per test step.

2. M =   1.5 bad DUT factor

3. ne number of (error) events. This parameter is the x‑ordinate in figure Annex 7 figure A7.1.3.1.

4. ns number of samples. The error rate is calculated from ne and ns.

Limit checking

Before limit checking is valid the minimum test time due to fading needs to be considered:

Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.

If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.

For an early decision a minimum number of (error) events is necessary.

For an early pass decision ne   ≥   1 (inclusive artificial error)

For an early fail decision ne   ≥   7

When the target test time has been reached the test is finished and a pass/fail decision can be made.

The error rate measured in this test shall be tested according to the values given in tables 14.11.1-2 or 14.11.1-3.

14.11.2.1a DARP Phase 1 Speech bearer test TCH/AFS DTS-1 in TIGHTER configuration

14.11.2.1a.1 Definition

The DARP reference test scenarios define a set of interfering signals and corresponding performance limits. These tests are a measure of the capability of the DARP receiver with additional TIGHTER requirements to receive a wanted modulated signal without exceeding a given degradation due to the presence of these specific unwanted modulated signals.

14.11.2.1a.2 Conformance requirement

1. A MS indicating support for TIGHTER capability (see 3GPP TS 24.008) shall fulfil the additional requirements in table 2ad for co channel interference (C/Ic), table 2af for adjacent channel (200 kHz) interference (C/Ia1), and the additional requirements in table 2ae for wanted signals on GMSK modulated channels for the test scenarios defined in annex L. The reference performance shall be:

– For speech channels (TCH/FS, TCH/HS, TCH/EFS, TCH/AFSx, TCH/AHSx, TCH/WFSx ) FER: £ 1 %

2. The values in table 2ae are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
In addition to table 6.3-6, for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2ad, 2ae, and 2af at the corresponding interference ratio C/Ic, C/I1, and C/Ia1, respectively.

3GPP TS 45.005, subclause 6.3

14.11.2.1a.3 Test purpose

To verify that the MS does not exceed the first conformance requirement for TCH/AFS under propagation condition TUhigh with an allowance for the statistical significance of the test.

To verify that the MS does not exceed the second conformance requirement for TCH/AFS under propagation condition TUhigh with an allowance for the statistical significance of the test.

14.11.2.1a.4 Method of test

14.11.2.1a.4.1 Initial conditions

A call is set up according to the generic call set up procedure on a TCH/AFS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.

The multirate configuration indicates the use of a codec set limited to 12,2 kbit/s.

The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal), with training sequence code (TSC) = 0.

The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).

14.11.2.1a.4.2 Procedure

a) In addition to the wanted signal, the SS produces an independent, uncorrelated interfering signal, Standard Test Signal I1 (unwanted signal).

The unwanted signal is continuous and has no fixed relationship with the bit transitions of the wanted signal. The interfering signal level is set to -80 dBm.

The fading characteristic of the wanted and the interfering signal is TUHigh.

b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.2.1a-2 or 14.11.2.1a-3.

c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.

d) The SS determines the number of residual bit error events for the bits of the class Ib, by examining at least the minimum number of samples of consecutive bits of class Ib. Bits are only taken from those frames not signalled as erased.

e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully it is not signalled as erased.

f) The SS uses a Channel Mode Modify procedure to change the active codec set to 10,2 kbit/s and steps b) to e) are repeated.

g) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,95 kbit/s and steps b) to e) are repeated.

h) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,4 kbit/s and steps b) to e) are repeated.

i) The SS uses a Channel Mode Modify procedure to change the active codec set to 6,7 kbit/s and steps b) to e) are repeated.

j) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,9 kbit/s and steps b) to e) are repeated.

k) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,15 kbit/s and steps b) to e) are repeated.

l) The SS uses a Channel Mode Modify procedure to change the active codec set to 4,75 kbit/s and steps b) to e) are repeated

Maximum/Minimum Duration of Test

Maximum: 75 minutes (GSM850), 75 minutes (GSM900), 75 minutes (DCS1800), 75 minutes (PCS1900).

Minimum: 27 minutes (GSM850), 26 minutes (GSM900), 13 minutes (DCS1800), 12 minutes (PCS1900).

14.11.2.1a.5 Test requirement

Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.

For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.

Before limit checking is valid the minimum test time due to fading needs to be considered:

14.11.2.2 DTS-4

14.11.2.2.1 Definition

The DARP reference test scenarios define a set of interfering signals and corresponding performance limits. These tests are a measure of the capability of the DARP receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of these specific unwanted modulated signals.

14.11.2.2.2 Conformance requirement

  1. MS indicating support for Downlink Advanced Receiver Performance – phase I (see 3GPP TS 24.008) shall fulfil the requirements in table 2o for wanted signals on GMSK modulated channels under TU50 no FH propagation conditions and GMSK modulated interferers for the test scenarios defined in annex L. The reference performance shall be:
  • For speech channels (TCH/FS, TCH/AFSx, TCH/AHSx) FER:  1 %
  1. The values in table 2o are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
    In addition for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2o at the corresponding C/I1.

3GPP TS 45.005, subclause 6.3

14.11.2.2.3 Test purpose

To verify that the MS does not exceed the first conformance requirement for TCH/AFS under propagation condition TUhigh with an allowance for the statistical significance of the test.

To verify that the MS does not exceed the second conformance requirement for TCH/AFS under propagation condition TUhigh with an allowance for the statistical significance of the test.

14.11.2.2.4 Method of test

14.11.2.2.4.1 Initial conditions

A call is set up according to the generic call set up procedure on a TCH/AFS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.

The multirate configuration indicates the use of a codec set limited to 12,2 kbit/s.

The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal), with training sequence code (TSC) = 0.

The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).

14.11.2.2.4.2 Procedure

a) In addition to the wanted signal, the SS produces one further interfering signal to produce scenario DTS-4.

A signal of type I5 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -77 dBm.

b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.2.2-2 or 14-11.2.2-3.

c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.

d) The SS determines the number of residual bit error events for the bits of the class Ib, by examining at least the minimum number of samples of consecutive bits of class Ib. Bits are only taken from those frames not signalled as erased.

e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully it is not signalled as erased.

f) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,9 kbit/s and steps b) to e) are repeated.

Maximum/Minimum Duration of Test

Maximum: 19 minutes (GSM850), 19 minutes (GSM900), 19 minutes (DCS1800), 19 minutes (PCS1900).

Minimum: 7 minutes (GSM850), 6 minutes (GSM900), 3 minutes (DCS1800), 3 minutes (PCS1900).

14.11.2.2.5 Test requirements

Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.

For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.

Wrong decision risk F for one single error rate test:

Fpass   =   Ffail   =   F and F   =   0.2%

Wrong decision probability D per test step:

Dpass   =   Dfail   =   D and D   =   0.0085%

Parameters for limit lines:

1. D =  0.000085 wrong decision probability per test step.

2. M =   1.5 bad DUT factor

3. ne number of (error) events. This parameter is the x‑ordinate in figure A7.1.3.1.

4. ns number of samples. The error rate is calculated from ne and ns.

Limit checking

Before limit checking is valid the minimum test time due to fading needs to be considered:

Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.

If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.

For an early decision a minimum number of (error) events is necessary.

For an early pass decision ne   ≥   1 (inclusive artificial error)

For an early fail decision ne   ≥   7

When the target test time has been reached the test is finished and a pass/fail decision can be made.

The error rate measured in this test shall be tested according to the values given in tables 14.11.2.2-2 or 14.11.2.2-3.

2. M =   1.5 bad DUT factor

3. ne number of (error) events. This parameter is the x‑ordinate in figure A7.1.3.1.

4. ns number of samples. The error rate is calculated from ne and ns.

Limit checking

Before limit checking is valid the minimum test time due to fading needs to be considered:

Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.

If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.

For an early decision a minimum number of (error) events is necessary.

For an early pass decision ne   ≥   1 (inclusive artificial error)

For an early fail decision ne   ≥   7

When the target test time has been reached the test is finished and a pass/fail decision can be made.

The error rate measured in this test shall be tested according to the values given in tables 14.11.2.2-2 or 14.11.2.2-3.

14.11.2.3 DTS-2/3/5

14.11.2.3.1 Definition

The DARP reference test scenarios define a set of interfering signals and corresponding performance limits. These tests are a measure of the capability of the DARP receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of these specific unwanted modulated signals.

14.11.2.3.2 Conformance requirement

1. MS indicating support for Downlink Advanced Receiver Performance – phase I (see 3GPP TS 24.008) shall fulfil the requirements in table 2o for wanted signals on GMSK modulated channels under TU50 no FH propagation conditions and GMSK modulated interferers for the test scenarios defined in annex L. The reference performance shall be:

– For speech channels (TCH/FS, TCH/AFSx, TCH/AHSx) FER:  1 %

2. The values in table 2o are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
In addition for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2o at the corresponding C/I1.

3GPP TS 45.005, subclause 6.3

14.11.2.3.3 Test purpose

To verify that the MS does not exceed the first conformance requirement for TCH/AFS under propagation condition TUhigh with an allowance for the statistical significance of the test.

To verify that the MS does not exceed the second conformance requirement for TCH/AFS under propagation condition TUhigh with an allowance for the statistical significance of the test.

14.11.2.3.4 Method of test

14.11.2.3.4.1 Initial conditions

A call is set up according to the generic call set up procedure on a TCH/AFS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.

The multirate configuration indicates the use of a codec set limited to 10,2 kbit/s.

The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal), with training sequence code (TSC) = 0.

The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).

14.11.2.3.4.2 Procedure

a) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-2.

A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.

A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.

A signal of type I1 using an ARFCN one higher than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.

A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.

b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.2.3-2 or 14.11.2.3-3, and sets the fading characteristic of the signal to TUHigh..

c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.

d) The SS determines the number of residual bit error events for the bits of the class Ib, by examining at least the minimum number of samples of consecutive bits of class Ib. Bits are only taken from those frames not signalled as erased.

e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully it is not signalled as erased.

f) The SS uses a Channel Mode Modify procedure to change the active codec set to 4,75 kbit/s and steps b) to e) are repeated.

g) The SS discontinues all interfering signals.

h) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-3.

A signal of type I4 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.

A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.

A signal of type I1 using an ARFCN one lower than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.

A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.

i) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,95 kbit/s and steps b) to e) are repeated.

j) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,15 kbit/s and steps b) to e) are repeated.

k) The SS discontinues all interfering signals.

l) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-5.

A signal of type I5 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -77 dBm.

A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.

A signal of type I1 using an ARFCN one higher than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.

A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.

m) The SS uses a Channel Mode Modify procedure to change the active codec set to 12,2 kbit/s and steps b) to e) are repeated.

n) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,9 kbit/s and steps b) to e) are repeated.

Maximum/Minimum Duration of Test

Maximum: 56 minutes (GSM850), 56 minutes (GSM900), 56 minutes (DCS1800), 56 minutes (PCS1900).

Minimum: 20 minutes (GSM850), 19 minutes (GSM900), 10 minutes (DCS1800), 9 minutes (PCS1900).

14.11.2.3.5 Test requirements

Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.

For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.

Wrong decision risk F for one single error rate test:

Fpass   =   Ffail   =   F and F   =   0.2%

Wrong decision probability D per test step:

Dpass   =   Dfail   =   D and D   =   0.0085%

Parameters for limit lines:

1. D =  0.000085 wrong decision probability per test step.

2. M =   1.5 bad DUT factor

3. ne number of (error) events. This parameter is the x‑ordinate in figure A7.1.3.1.

4. ns number of samples. The error rate is calculated from ne and ns.

Limit checking

Before limit checking is valid the minimum test time due to fading needs to be considered:

Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

The reference performance shall be:

– For speech channels (TCH/FS, TCH/HS, TCH/EFS, TCH/AFSx, TCH/AHSx, TCH/WFSx ) FER: £ 1 %

2. The values in table 2ae are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).

A signal of type I1 using an ARFCN one higher than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.

A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.

m) The SS uses a Channel Mode Modify procedure to change the active codec set to 12,2 kbit/s and steps b) to e) are repeated.

n) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,9 kbit/s and steps b) to e) are repeated.

Maximum/Minimum Duration of Test

Maximum: 56 minutes (GSM850), 56 minutes (GSM900), 56 minutes (DCS1800), 56 minutes (PCS1900).

Minimum: 20 minutes (GSM850), 19 minutes (GSM900), 10 minutes (DCS1800), 9 minutes (PCS1900).

14.11.3 TCH/AHS

14.11.3.1 DTS-1

14.11.3.1.1 Definition

The DARP reference test scenarios define a set of interfering signals and corresponding performance limits. These tests are a measure of the capability of the DARP receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of these specific unwanted modulated signals.

14.11.3.1.2 Conformance requirement

1. MS indicating support for Downlink Advanced Receiver Performance – phase I (see 3GPP TS 24.008) shall fulfil the requirements in table 2o for wanted signals on GMSK modulated channels under TU50 no FH propagation conditions and GMSK modulated interferers for the test scenarios defined in annex L. The reference performance shall be:

– For speech channels (TCH/FS, TCH/AFSx, TCH/AHSx) FER:  1 %

2. The values in table 2o are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
In addition for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2o at the corresponding C/I1.

3GPP TS 45.005, subclause 6.3

14.11.3.1.3 Test purpose

To verify that the MS does not exceed the first conformance requirement for TCH/AHS under propagation condition TUhigh with an allowance for the statistical significance of the test.

To verify that the MS does not exceed the second conformance requirement for TCH/AHS under propagation condition TUhigh with an allowance for the statistical significance of the test.

14.11.3.1.4 Method of test

14.11.3.1.4.1 Initial conditions

A call is set up according to the generic call set up procedure on a TCH/AHS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.

The multirate configuration indicates the use of a codec set limited to 7,95 kbit/s.

The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal), with training sequence code (TSC) = 0.

The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).

14.11.3.1.4.2 Procedure

a) In addition to the wanted signal, the SS produces one further interfering signal to produce scenario DTS-1.

A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.

b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.3.1-2 or 14.11.3.1-3.

c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.

d) The SS determines the number of residual bit error events for the bits of the class Ib and II, by examining at least the minimum number of samples of consecutive bits of class Ib and II. Bits are only taken from those frames not signalled as erased.

e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully if it is not signalled as erased.

f) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,4 kbit/s and steps b) to e) are repeated.

g) The SS uses a Channel Mode Modify procedure to change the active codec set to 6,7 kbit/s and steps b) to e) are repeated.

h) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,9 kbit/s and steps b) to e) are repeated.

i) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,15 kbit/s and steps b) to e) are repeated.

  1. The SS uses a Channel Mode Modify procedure to change the active codec set to 4,75 kbit/s and steps b) to e) are repeated.

Maximum/Minimum Duration of Test

Maximum: 56 minutes (GSM850), 56 minutes (GSM900), 56 minutes (DCS1800), 56 minutes (PCS1900).

Minimum: 41 minutes (GSM850), 38 minutes (GSM900), 19 minutes (DCS1800), 18 minutes (PCS1900).

14.11.3.1.5 Test requirements

Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.

For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.

Wrong decision risk F for one single error rate test:

Fpass   =   Ffail   =   F and F   =   0.2%

Wrong decision probability D per test step:

Dpass   =   Dfail   =   D and D   =   0.0085%

Parameters for limit lines:

1. D =  0.000085 wrong decision probability per test step.

2. M =   1.5 bad DUT factor

3. ne number of (error) events. This parameter is the x‑ordinate in figure A7.1.3.2.

4. ns number of samples. The error rate is calculated from ne and ns.

Limit checking

Before limit checking is valid the minimum test time due to fading needs to be considered:

Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.

If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.

For an early decision a minimum number of (error) events is necessary.

For an early pass decision ne   ≥   1 (inclusive artificial error)

For an early fail decision ne   ≥   7

When the target test time has been reached the test is finished and a pass/fail decision can be made.

The error rate measured in this test shall be tested according to the values given in tables 14.11.3.1-2 or 14.11.3.1-3.

14.11.3.1a DARP Phase 1 Speech bearer test TCH/AHS DTS-1 in TIGHTER configuration

14.11.3.1a.1 Definition

The DARP reference test scenarios define a set of interfering signals and corresponding performance limits. These tests are a measure of the capability of the DARP receiver with additional TIGHTER requirements to receive a wanted modulated signal without exceeding a given degradation due to the presence of these specific unwanted modulated signals.

14.11.3.1a.2 Conformance requirement

1. A MS indicating support for TIGHTER capability (see 3GPP TS 24.008) shall fulfil the additional requirements in table 2ad for co channel interference (C/Ic), table 2af for adjacent channel (200 kHz) interference (C/Ia1), and the additional requirements in table 2ae for wanted signals on GMSK modulated channels for the test scenarios defined in annex L. The reference performance shall be:

– For speech channels (TCH/FS, TCH/HS, TCH/EFS, TCH/AFSx, TCH/AHSx, TCH/WFSx ) FER: £ 1 %

2. The values in table 2ae are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
In addition to table 6.3-6, for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2ad, 2ae, and 2af at the corresponding interference ratio C/Ic, C/I1, and C/Ia1, respectively.

3GPP TS 45.005, subclause 6.3

14.11.3.1a.3 Test purpose

To verify that the MS does not exceed the first conformance requirement for TCH/AHS under propagation condition TUhigh with an allowance for the statistical significance of the test.

To verify that the MS does not exceed the second conformance requirement for TCH/AHS under propagation condition TUhigh with an allowance for the statistical significance of the test.

14.11.3.1a.4 Method of test

14.11.3.1a.4.1 Initial conditions

A call is set up according to the generic call set up procedure on a TCH/AHS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.

The multirate configuration indicates the use of a codec set limited to 7,95 kbit/s.

The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal), with training sequence code (TSC) = 0.

The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).

14.11.3.1a.4.2 Procedure

a) In addition to the wanted signal, the SS produces one further interfering signal to produce scenario DTS-1.

A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.

b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.3.1a-2 or 14.11.3.1a-3.

c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.

d) The SS determines the number of residual bit error events for the bits of the class Ib and II, by examining at least the minimum number of samples of consecutive bits of class Ib and II. Bits are only taken from those frames not signalled as erased.

e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully if it is not signalled as erased.

f) The SS uses a Channel Mode Modify procedure to change the active codec set to 7,4 kbit/s and steps b) to e) are repeated.

g) The SS uses a Channel Mode Modify procedure to change the active codec set to 6,7 kbit/s and steps b) to e) are repeated.

h) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,9 kbit/s and steps b) to e) are repeated.

i) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,15 kbit/s and steps b) to e) are repeated.

j) The SS uses a Channel Mode Modify procedure to change the active codec set to 4,75 kbit/s and steps b) to e) are repeated.

Maximum/Minimum Duration of Test

Maximum: 56 minutes (GSM850), 56 minutes (GSM900), 56 minutes (DCS1800), 56 minutes (PCS1900).

Minimum: 41 minutes (GSM850), 38 minutes (GSM900), 19 minutes (DCS1800), 18 minutes (PCS1900).

14.11.3.1a.5 Test requirement

Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.

For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.

Before limit checking is valid the minimum test time due to fading needs to be considered:

14.11.3.2 Void

14.11.3.3 DTS-2/3

14.11.3.3.1 Definition

The DARP reference test scenarios define a set of interfering signals and corresponding performance limits. These tests are a measure of the capability of the DARP receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of these specific unwanted modulated signals.

14.11.3.3.2 Conformance requirement

  1. MS indicating support for Downlink Advanced Receiver Performance – phase I (see 3GPP TS 24.008) shall fulfil the requirements in table 2o for wanted signals on GMSK modulated channels under TU50 no FH propagation conditions and GMSK modulated interferers for the test scenarios defined in annex L. The reference performance shall be:

– For speech channels (TCH/FS, TCH/AFSx, TCH/AHSx) FER:  1 %

  1. The values in table 2o are given as the C/I1 ratio, where C is the power level of the wanted signal and I1 is the power level of the dominant co-channel interferer (Co-channel 1, see annex L).
    In addition for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 2o at the corresponding C/I1.

3GPP TS 45.005, subclause 6.3

14.11.3.3.3 Test purpose

To verify that the MS does not exceed the first conformance requirement for TCH/AHS under propagation condition TUhigh with an allowance for the statistical significance of the test.

To verify that the MS does not exceed the second conformance requirement for TCH/AHS under propagation condition TUhigh with an allowance for the statistical significance of the test.

14.11.3.3.4 Method of test

14.11.3.3.4.1 Initial conditions

A call is set up according to the generic call set up procedure on a TCH/AHS with an ARFCN in the mid ARFCN range, power control level set to maximum power. RADIO_LINK_TIMEOUT is set to maximum.

The multirate configuration indicates the use of a codec set limited to 7,4 kbit/s.

The SS transmits Standard Test Signal C1 on the traffic channel (wanted signal), with training sequence code (TSC) = 0.

The SS commands the MS to create the traffic channel loop back, signalling erased frames (subclause 36).

14.11.3.3.4.2 Procedure

a) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-2.

A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.

A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.

A signal of type I1 using an ARFCN one higher than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.

A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.

b) The SS sets the level of the wanted signal to that indicated by Clev in table 14.11.3.3-2 or 14.11.3.3-3, and sets the fading characteristic of the signal to TUHigh..

c) The SS compares the modulation of the signal that it sends to the MS with the signal which is looped back from the receiver after demodulation and decoding, and checks the frame erasure indication.

d) The SS determines the number of residual bit error events for the bits of the class Ib and II, by examining at least the minimum number of samples of consecutive bits of class Ib and II. Bits are only taken from those frames not signalled as erased.

e) The SS also determines the frame erasure events by examining at least the minimum number of samples of consecutive frames and assuming a frame is received successfully if it is not signalled as erased.

f) The SS uses a Channel Mode Modify procedure to change the active codec set to 4,75 kbit/s and steps b) to e) are repeated.

g) The SS discontinues all interfering signals.

h) In addition to the wanted signal, the SS produces a further four interfering signals to produce scenario DTS-3.

A signal of type I4 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -80 dBm.

A signal of type I1 using the same ARFCN as C1, with fading characteristics of TUHigh, and signal level of -90 dBm.

A signal of type I1 using an ARFCN one lower than C1, with fading characteristics of TUHigh, and signal level of -77 dBm.

A signal of type I3 using the same ARFCN as C1, and signal level of -97 dBm.

i) The SS uses a Channel Mode Modify procedure to change the active codec set to 6,7 kbit/s and steps b) to e) are repeated.

j) The SS uses a Channel Mode Modify procedure to change the active codec set to 5,15 kbit/s and steps b) to e) are repeated.

Maximum/Minimum Duration of Test

Maximum: 38 minutes (GSM850), 38 minutes (GSM900), 38 minutes (DCS1800), 38 minutes (PCS1900).

Minimum: 27 minutes (GSM850), 26 minutes (GSM900), 13 minutes (DCS1800), 12 minutes (PCS1900).

14.11.3.3.5 Test requirements

Testing should be performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with FER/BER not on the limit.

For more information on statistical testing of BER/BLER performance, especially the definition of limit lines refer to Annex 7.

Wrong decision risk F for one single error rate test:

Fpass   =   Ffail   =   F and F   =   0.2%

Wrong decision probability D per test step:

Dpass   =   Dfail   =   D and D   =   0.0085%

Parameters for limit lines:

1. D =  0.000085 wrong decision probability per test step.

2. M =   1.5 bad DUT factor

3. ne number of (error) events. This parameter is the x‑ordinate in figure A7.1.3.1.

4. ns number of samples. The error rate is calculated from ne and ns.

Limit checking

Before limit checking is valid the minimum test time due to fading needs to be considered:

Testing under multipath and interference conditions requires that at least 990 wavelengths are crossed with the speed given in the fading profile. This leads to a minimum test time depending on the frequency range. No early pass/fail decision is allowed until the minimum test time due to fading has elapsed.

If the minimum test time due to multipath conditions exceeds the target test time, then the test runs for the minimum test time due to multipath conditions and the decision is made by comparing the result with the “derived test limit”. In this case early pass/fail decisions are obsolete.

If the target test time exceeds the minimum test time due to multipath conditions early pass/fail decisions can be headed for in order to accelerate test execution.

For an early decision a minimum number of (error) events is necessary.

For an early pass decision ne   ≥   1 (inclusive artificial error)

For an early fail decision ne   ≥   7

When the target test time has been reached the test is finished and a pass/fail decision can be made.

The error rate measured in this test shall be tested according to the values given in tables 14.11.3.3-2 or 14.11.3.3-3.
