14.2.30 Reference sensitivity TCH/AFS in VAMOS configuration

3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS

14.2.30.1 Definition

The reference sensitivity is the signal level at the MS receiver input at which a certain BER and FER must be achieved.

14.2.30.2 Conformance requirement

The reference performance in VAMOS Mode, shall be

– For full rate speech channels (TCH/FS, TCH/AFSx, TCH/EFS, TCH/WFSx ) FER:  1 %

3GPP TS 45.005 subclause 6.2.1a

For speech channels in VAMOS Mode, and their associated control channels, the minimum input signal level for which the reference performance shall be met is specified in table 1s, 1t, 1u, 1v, 1x and 1yaccording to the propagation condition and type of equipment. The levels are given for VAMOS I MS, VAMOS II MS, VAMOS III MS and normal BTS separately.

3GPP TS 45.005 subclause 6.2.1a

In addition for speech channels the residual class Ib BER and residual class II BER performance shall not exceed the specified values in table 1s, 1t, 1u, 1x, 1y and 1v at the corresponding signal level in dBm.

3GPP TS 45.005 subclause 6.2.1a

14.2.30.3 Test purpose

1. To verify that the MS does not exceed conformance requirements under propagation condition TUhigh with no frequency hopping with an allowance for the statistical significance of the test.

14.2.30.4 Method of test

NOTE 1: The BA list sent on the BCCH and SACCH will indicate at least six surrounding cells with at least one near to each band edge. It is not necessary to generate any of these BCCHs but, if provided the signal strengths of BCCHs shall be in the range 15 dBVemf(  ) to 35 dBVemf(  ).

NOTE 2: The ARFCN of any BCCH shall not be co-channel or on adjacent channels to the wanted traffic channel.

14.2.30.4.1 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 12.20 kbit/s.

The SS transmits a Standard Test Signal C1 (AQPSK) (wanted signal) on the active VAMOS subchannel (subchannel 2) using trainings sequence 5 from TSC set 2. The other VAMOS subchannel (subchannel 1) uses trainings sequences 5 from TSC set 1.

The SS commands the MS to create traffic channel loop back signalling erased frames.

Specific PICS Statements:

– VAMOS I supported (TSPC_VAMOS_Type1)

– VAMOS II supported (TSPC_VAMOS_Type2)

– VAMOS III supported (TSPC_VAMOS_Type3)

For MS indicating VAMOS III support, connect the SS to the MS antenna connectors according to Annex A1.1.6.2.

14.2.30.4.2 Procedure

a) The fading function is set to TUhigh for MS indicating VAMOS I or VAMOS II support and TUhigh/(Corr.=0, AGI=0 dB as per 3GPP TS 45.005 Annex Q.7) for MS indicating VAMOS III support.

b) The SS sets SCPIR_DL to +4 dB.

c) Depending of the indicated VAMOS type and the relevant antenna correlation and antenna gain imbalance values, the SS sets the amplitude of the wanted signal to reference sensitivity level from table 1s for VAMOS I or table 1t for VAMOS II or table 1x for VAMOS III in TS 45.005.

d) The SS compares the data 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.

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

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

g) The SS repeats steps c) to f) with SCPIR_DL values 0 dB and -4 dB.

h) For MS indicating VAMOS II or VAMOS III support, step c) to f) shall be repeated with SCPIR_DL values -8 dB and -10 dB.

i) The SS uses a Channel Mode Modify procedure to change the active codec set to 4.75 kbit/s and steps b) to h) are repeated.

j) For MS indicating VAMOS III support, steps b) to i) are repeated with the SS fading function set in turn to TU high/(Corr.=0,7, AGI=-6 dB as per 3GPP TS 45.005 Annex Q.7).

Maximum/Minimum Duration of Test

– Maximum (VAMOS I): 56 minutes (GSM850, GSM900) or 56 minutes (DCS1800, PCS1900).

– Minimum (VAMOS I): 19 minutes (GSM850, GSM900) or 9 minutes (DCS1800, PCS1900).

– Maximum (VAMOS II): 94 minutes (GSM850, GSM900) or 94 minutes (DCS1800, PCS1900).

– Minimum (VAMOS II): 32 minutes (GSM850, GSM900) or 15 minutes (DCS1800, PCS1900).

– Maximum (VAMOS III): 94 minutes (GSM850, GSM900) or 94 minutes (DCS1800, PCS1900).

– Minimum (VAMOS III): 32 minutes (GSM850, GSM900) or 15 minutes (DCS1800, PCS1900).

14.2.30.5 Test requirements

Testing the reference sensitivity performance is performed using statistical methods that lead to an early pass/fail decision with test time significantly reduced for MS with BER/BLER not on the limit.

For more information on statistical testing of BER/BLER performance, especially the definition of the limit lines refer to Annex 7.1 (A7.1.3.2)

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

The error rates measured for different channels and under the different propagation conditions shall be tested according to the values given in tables 14.2.30-2 through 14.2.30-9 depending on the indicated VAMOS type and the relevant antenna correlation and antenna gain imbalance values.

Reference sensitivity tests with a frequency condition noted as “@+/-ndB” are performed for SCPIR_DL ndB (see 3GPP TS 45.005).
