3 Terms, definitions and abbreviations
3.1 Terms and definitions
The following terms and definitions apply to this document.
3.1.1
Block error rate
The block error rate, the calculation of which shall be based on the
estimation of the cyclic redundancy verification for each transmission block.
3.1.4
Ancillary equipment
It refers to the equipment (device) connected to the receiver, transmitter or
transceiver, AND the following conditions are met simultaneously.
3.1.5
Fixed station
It refers to the UE which is used at a fixed position AND is powered by AC
power source.
3.1.6
Idle mode
It refers to a working mode of the UE receiver or transceiver. In this mode,
the equipment under test (EUT) is powered up to provide service AND is
able to respond to the requirements for establishing a call.
3.1.7
Traffic mode
It refers to a working mode of the UE receiver or transceiver. In this mode,
the equipment under test (EUT) is powered up AND establishes a
communication link with the radio resource controller.
3.1.8
Spurious emissions
It refers to the disturbance on the discrete frequency other than the carrier
frequency and the normal modulation related side band. It can be divided
into conduction and radiation.
3.1.9
Load dump
When alternator produces charging current normally, the charging battery is
disconnected from the alternator, and there are still other loads connected to
the alternator circuit.
3.2 Abbreviations
The following abbreviations apply to this document.
4 Test conditions
4.1 General conditions
The EUT shall be tested in a normal test environment. The test conditions shall
be recorded in the report.
4.2 Test arrangement
4.2.1 Transmitter input end test arrangement
Appropriate normal modulation signal is produced through the internal or
external signal source AND is sent into the input port of the transmitter. The
external signal source shall be located outside the test environment.
SS shall ensure continuous EUT emission.
4.2.3 Receiver input end test arrangement
SS shall be placed outside the test environment.
The frequency of the available RF input signal for providing the communication
link is selected by setting the correct UTRA ARFCN. Unless the other clauses
of this part have special requirements, the test shall select the UTRA ARFCN
corresponding to the center frequency of the operating frequency band.
4.2.4 Receiver output end test arrangement
For audio equipment, the audio output of the receiver shall be connected to an
audio distortion analyzer or other similar measurement instrument located
outside the test environment via a nonconductive acoustic tube. For those
which cannot use the nonconductive acoustic tubes, it may use other methods
to connect the output of the receiver to an audio distortion analyzer or other
similar measurement instrument, AND it shall be recorded in the test report.
4.3 Test-exempted frequency band
The test-exempted frequency band is the frequency band that does not
subjected to the radiation immunity test.
The ancillary equipment does not have the test-exempted frequency band.
4.4 Narrowband response of receiver
The narrowband response generated by the receiver and the transceiver
during the discrete frequency test is determined by the following method.
In the immunity test, it shall monitor the BLER and speech output signal level.
Both narrowband response and wideband phenomena may cause an increase
in BLER or speech output signal levels. In this case, further judgment is
required.
4.5 Continuous disturbance measurement conditions and
arrangement
Measurements shall be made in the mode in which the EUT is working with
maximum disturbance.
4.6 Immunity test conditions and arrangements
4.6.1 The immunity test shall be carried out in two operating modes.
a) Traffic mode;
b) Idle mode.
4.6.2 When the EUT is an analog speech or audio signal transmission mode,
the test arrangement shall be carried out in accordance with the following
conditions.

The EUT shall comply with the minimum performance criteria as specified in
6.2 and 6.3 below.
The maintaining of communication connection shall be evaluated by an
indicator, which may be part of the SS or EUT.

After the test, the EUT shall be able to work properly, there is no
communication quality degradation which is perceivable by the user, there is
no loss of user control functions or loss of stored data, AND the communication
connection is maintained.
