About this document

1 About this document 1.1 Scope

This document incorporates functional test phase and defines the test cases for

the Space-Time Interference Rejection Combining (STIRC) feature of the BTS

software release CXM5 for MetroSite. The test cases are used to verify that the

BTS configured with the feature works as specified.

Note 1.

The BSC version to be used is S12 unless otherwise specified.

Note 2.

At the BSC, Base Transceiver Stations (sites) are seen as BCFs. Sectors are

referred to as BTS. This principle is followed in the test Description in this

document.

Note 3.

All test cases are performed with BTS Manager connected, unless otherwise

stated.

Note 4.

For all tests that require TRX test to be run, the PMAX value should be set as

maximum (that is, 0).

Note 5.

This feature is only supported by EDGE TRXs of MetroSite.



5 (21)




Note 6.

(HS)CSD rig is a setup of laptops and phones to enable the testing of these

features.

Note 7.

The IR/LA rig is a setup of equipment that allow introduction of interference on

the air interface so that bad conditions on the RF path can be simulated.

2.5 TRX Test and TRX Loop Test

Purpose:

The purpose of the following tests is to check that the TRX Test can be

executed successfully on the TRXs of a STIRC-enabled sector.

Acceptable test results

The acceptable test results for this test are:

• BER = 0%

• RX Sensitivity:

− -110.5 dBm (or better) for GSM 900 and GSM 800

− -111 dBm (or better) for GSM 1800 and GSM 1900



13 (21)




• The GMSK sensitivity is typically -111 to -113 dBm, MCS-5 is -107 to -

109 dBm and MCS-9 is -97 to -99 dBm.

• PMAX value should be set as maximum (that is, 0).

• The threshold values of TRX performance test need to be defined as thedefault values. The default threshold or TRX performance test values for

MetroSite are:

Transmitted Metro Power (PWRM) = 30 dBm

Transmitted Metro HP Power (PWRH) = 37 dBm

BER (BER) = 0.2000%

RX Sensitivity (MSENS) = -100 dBm

At the BSC, the current threshold values of TRX performance test can be

verified using the following MML command:ZUCV: TRP, CURRENT;

If the current threshold values differ from the default ones, they should be

modified with the following MML command:

ZUCV: TRP, MODI FY: PWRU=<pwr u_val >, BER=<ber _val >, MSENS=<msens_ val >;

The expected range of TX power level from the TRX Test is:

transmitted power level dBm – PMAX + 4dBm

Note 8.

When the test is started from BTS Manager, alarm 7615 RTS IS IN TEST USE

for the used TS is started.

When BTS Manager finishes the test, alarm 7615 RTS IS IN TEST USE for the

used TS is cancelled.

The alarm may not be included in the alarm history at the BSC as the BSC uses

time-window based filtering for alarm reporting. That is, if an alarm is started

and cancelled within 10 seconds.

Note 9.

When running the TRX Test from the BSC, only MCS-5 is supported with 8-

PSK modulation.





Test cases


BCF is in Supervisory state.

1. For an EDGE sector, configure DAP andEGENA. EGENA is configured successfully.

2. Enable STIRC for both sectors with thefollowing MML command:





4. See the traces using Trace master. The INI message contains the STIRC option as

enabled.5. Make a call using the TRX being tested. Call is successful.

6. A TRX test is started from the BSC usingthe following MML command:

ZUBS

for 8-PSK modulation method.

The test is started.

7. The test results are checked with thefollowing MML command:

ZUBP

The used TX power level is verified withthe Spectrum Analyser.

The test is successful and the test results areacceptable, as defined in the explanation abovethis table.

Note:

The used TX power level is the same as theBCCH TX power level.

The test is not started for control channels orchannels with an active call.

The test takes no more than 5 seconds.

The call is not affected, that is, the call is notdropped and there are no additional disturbingsounds heard at the receiving end.

8. The test is repeated for every TSs in bothBCCH and non-BCCH TRXs in both

sectors. The colour of unit LEDs is verified at theBTS and the BTS Manager equipmentview.

The test is started for idle channels.

The colour of the TRX LEDs at the BTS remains

green during the test.

The test is not started for control channels orchannels with an active call, and the colour of the TRX at the BTS and BTS Manager remainsgreen.
