2.2.9         Total receiver radiation sensitivity

This technical requirement applies to UEs with dimensions greater than or equal to 56 mm and less than or equal to 72 mm.

2.2.9.1         Definition

The total radiation sensitivity is defined as follows:

Wherein, Effective Isotropic Sensitivity (EIS) is defined as the power at the antenna output, i.e. the sensitivity threshold achieved at each polarization. Ω is the azimuth angle,  is the frequency. θ and φ are orthogonal polarization angles.

In which, N and M are the numbers of sampling intervals corresponding to θ and φ.  the measuring angles. Sampling intervals are specified in 4.4 of ETSI TS 137 544.

The calculation of TRS in this case is based on finding the lowest power received by the UE for a finite number of field combinations in the measurement chamber that produces a BER level better than the specified BER. By calibrating the average power transfer function, the absolute value of TRS can be obtained. The following formula is used to calculate TRS.

In which, P_ref,_n is the reference power conversion function for fixed measurement antenna; n, Rn is the reflection coefficient for fixed measurement antenna; n, Cn is the path loss in the cable connecting from the measurement receiver to the antenna fixed measuring n.

Therefore:

In which, N and M are the numbers of sampling intervals corresponding to θ and φ.  are the measuring angles. Sampling intervals are specified in 4.4 of ETSI TS 137 544.

The TRP can be calculated from the Rayleigh fading patterns of the total power emitted from the UE. Measurement of transmitter power in an isotropic Rayleigh fading medium is based on sampling the UE's radiated power for a finite number of field combinations in the measurement chamber. The average value of the samples is statistically distributed corresponding to TRP and by adjusting the average power transfer function, from which the absolute value of TRP is calculated.

Therefore:

In which, is the reference power conversion function for fixed measurement antenna n, Rn is the reflection coefficient for fixed measurement antenna n, Cn is the path loss in the cable connecting from the measurement receiver to the antenna fixed measuring name n. These parameters are calculated from calibration measurements and are specified in B.2 of ETSI TS 137 544. are the average power values ​​measured by fixed antenna n and are calculated using the following formula:

2.2.10.2    Limitation

The average value of the measured total radiated power of the low, medium and high channels at the position next to the head must be greater than the value specified in Table 15. Averaging should be performed on a linear scale for the TRP results for the left and right sides of the prosthetic head.

Table 15 – Minimum TRP value limit

NOTE:        The minimum TRS requirement applies to UEs with dimensions greater than or equal to 56 mm and less than or equal to 72 mm as defined in ETSI TR 125 914.

2.     MEASUREMENT METHODS

3.1.    Environmental conditions

Testing is performed at representative limit points in the operating environment disclosed in the file.

Measurements must be performed under a full range of environmental conditions (within the published limits of the device's operating environment) to determine compliance with technical requirements.

Normally, the device should achieve all measurements using the conductivity method under normal conditions, unless otherwise specified. Guidance on the use of other conditions uses reference ETSI TS 136 521-1.

For each UE operating band, measurements are performed with the appropriate frequency defined in ETSI TS 136 508.

3.2.    Interpretation of measurement results

The results recorded in the measurement report for the measurements described in this regulation are as follows:

-       The measured value is related to the corresponding limit used to decide whether the device meets the requirements of the standard or not;

-       The measurement uncertainty value for the measurement of each parameter shall be included in the test report;

-       For each measurement, the recorded value of the measurement uncertainty shall be less than or equal to the value given in Table 17 and Table 18. According to this standard, in measurement methods, the values ​​of measurement uncertainty must be calculated and must be equivalent to the expansion factor (coverage factor) k = 1.96 (for a confidence level of 95 % in case the distributions characterizing the actual measurement uncertainty are normal (Gaussian). The principles for calculating measurement uncertainty are presented in TR 100 028, special cases in Annex C of ETSI TR 100 028-2. Guidance on the use of other measuring conditions uses reference ETSI TS 136 521-1.

Table 17 - Maximum measurement uncertainty of the test system

Table 18 - Maximum measurement uncertainty for radiated emissions, control and monitoring functions

NOTE 1: For RF measurements, it must be noted that the internal uncertainty Table 17 Applies to a test system operating with a nominal load of 50 Ω and does not take into account system effects due to mismatch between the EUT and the test system.

NOTE 2: If the test system has a measurement uncertainty greater than the measurement uncertainty specified in Table 17, the equipment may still be used, provided the following adjustments are made: Any additional uncertainties in the Test System beyond those specified in Table 17 can be used to tighten measurement requirements - making the measurement more difficult to pass (for some measurements, e.g. receiver measurements, this may require changing the excitation signals ). This procedure ensures that the measuring system does not meet the internal requirements Table 17, will not increase the likelihood of the EUT passing the measurements in the event that the EUT would be judged to fail if a measurement system that meets the requirements in Table 17.

- With an established communication link (traffic mode); and

- In idle mode.

3.3.15.           Control and monitoring functions

1) When starting the test, the UE must be turned off. The UE antenna connector must be connected to a power measuring device with the following characteristics:

- RF bandwidth must be larger than the total operating frequency range of the UE;

- The response time of the power measuring device must ensure that the measured power is no more than 1 dB compared to the measured power at steady state within 100 μs when a CW signal is applied.

- The device must record the measured peak power.

NOTE:        The device may include a visual frequency low-pass filter to minimize the UE response to electrical spikes or to Gaussian noise peaks.

2) Turn on the UE for about 15 min, then turn off the UE.

3) The EUT is maintained off for at least 30 s, then switched on for approximately 1 min.

4) Record the maximum power radiated from the UE during the testing period.

Environmental conditions

A.1. Introduce

This Annex regulates the environmental conditions of the UE.

A.2. Temperature

The UE fully meets the temperature range requirements as shown in Table A.1.

Table A.1 - Temperature conditions

Outside this temperature range, if power is on, the UE must not cause harmful effects to the radio frequency spectrum. In no case shall the UE exceed the transmit power levels as defined in ETSI TS 136 101 for critical conditions.

The reference for this requirement is E.1 of ETSI TS 136 101.

Some tests were performed under critical temperature conditions. These testing conditions are denoted as TL (Lower Critical Temperature, -10° C) and TH (Upper Critical Temperature, +55° C).

A.3. Voltage

The UE fully meets the voltage range requirements, i.e. the voltage range within the critical voltage points.

The manufacturer shall declare the lower and upper limit voltages and the approximate shutdown voltage. For equipment that may operate from one or more of the power sources listed below, the lower critical voltage shall not be higher and the upper critical voltage not lower than specified below.

Table A.2 - Test voltage conditions

Outside this voltage range, if the power is turned on, the UE must not cause harmful effects on the radio frequency spectrum. In no case shall the UE exceed the transmit power levels as defined in ETSI TS 136 101 for critical conditions. In particular, the UE must block all RF emissions when the supply voltage is below the manufacturer's declared shutdown voltage.

The standard reference for this requirement is E.2 of ETSI TS 136 101.

Some tests are performed under critical voltage conditions. These testing conditions are denoted as VL (Lower Critical Voltage) and VH (Upper Critical Voltage).

A.4. Testing environment

When testing under normal environmental conditions is required, the normal conditions in A.2 and A.3 applied.

When testing at extreme conditions is required, the combination of the extreme temperature and extreme voltage conditions in A.2 and A.3 applied. These combinations include:

-         Lower Critical Temperature / Lower Critical Voltage (TL/VL);

-         Lower Critical Temperature / Upper Critical Voltage (TL/VH);

-         Upper Critical Temperature / Lower Critical Voltage (TH/VL);

-         Upper Critical Temperature / Upper Critical Voltage (TH/VH).
