14.12.1.1 FACCH – DTS-1

14.12.1.1.1 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.

14.12.1.1.2 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 signalling channels (FACCH/F, SDCCH) FER:  5 %

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).

3GPP TS 45.005, subclause 6.3

14.12.1.1.3 Test purpose

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

14.12.1.1.4 Method of test

14.12.1.1.4.1 Initial conditions

A call is set up according to the generic call set up procedure on a TCH/F with an ARFCN in the mid ARFCN range. The 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).

14.12.1.1.4.2 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 14-12.1.1.4.2 (GSM 900 / 850) and table 14-12.1.1.4.3 (DCS 1800 / 1900).

  1. The SS sends a Layer 3 message which does not require a Layer 3 response from the MS. Each repeated L2 frame indicates a frame erasure event.
  2. The SS determines the number of frame erasure events during at least the minimum number of samples of FACCH/F frames.

NOTE: These frames will not be consecutive but it is expected that the statistical significance of the tests will not be unduly degraded.

14.12.1.1.4.3 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 14‑1.

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 table 14-12.1.1.4.2
