2.2.12.Receiver Total Radiated Sensitivity

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

1. - Methods using measuring devices: The minimum number of sampled calls required for each of the above indicators is 1,500 calls. Determination can be made using one or both of the following methods, or a combination thereof:

Total radiated sensitivity is defined as follows:

 

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

 

Where N and M are the number of sampling intervals corresponding to θ and φ respectively.  and  are the measured angles. The sampling intervals are specified in 4.4 of ETSI TS 137 544.

TRS can be calculated from three-dimensional isotropic Rayleigh phase-coherent measurements in uniform azimuth and elevation angle distributions. In this case, the calculation of TRS is based on finding the lowest power that the UE receives for a finite set of field combinations in the test chamber that result in a better BER than the specified BER. By calibrating the mean power transfer function, the absolute value of TRS can be obtained. The following formula is used to calculate TRS.

 

Where  is the reference power transfer function for fixed antenna n, R_n is the reflection coefficient for fixed antenna n, C_n is the transmission loss in the cable connecting the receiver under test to fixed antenna n.

2.2.13.Total Radiated Power

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

1. - Methods using measuring devices: The minimum number of sampled calls required for each of the above indicators is 1,500 calls. Determination can be made using one or both of the following methods, or a combination thereof:

Where:  is the azimuth angle, f is the frequency.

                 θ and φ are orthogonal polarization angles.

                   and  are the actual transmitted power levels for the corresponding polarizations.

Therefore:

 

Where N and M are the number of sampling intervals corresponding to θ and φ respectively.  and  are the measured angles. The sampling intervals are specified in 4.4 of ETSI TS 137 544.

TRP can be calculated from the Rayleigh phase-coherent samples of the total emitted power from the UE. The measurement of the transmitter power in an isotropic Rayleigh phase-coherent environment is based on sampling the UE's radiated power for a finite set of field combinations in the test chamber. The average of the samples is statistically distributed corresponding to TRP, and by calibrating the mean power transfer function, the absolute value of TRP is obtained.

Therefore:

 

Where  is the reference power transfer function for fixed antenna n, R_n is the reflection coefficient for fixed antenna n, C_n is the transmission loss in the cable connecting the receiver under test to fixed antenna n.

This criterion may be applicable to radio communication equipment and ancillary equipment.

This criterion must be measured on the radio communication device and/or on typical configurations of auxiliary equipment.

1. Limit

Measured power during the measurement period must not exceed -30 dBm.

3.MEASUREMENT METHODS

3.1.Environmental Conditions

Measurements are carried out at representative limit points in the operational environment specified in the documentation.

Measurements must be performed under all different environmental conditions (within the published operational environment limits of the equipment) to determine compliance with technical requirements.

Normally, the equipment must pass all measurements using the standard test method in normal conditions, except where otherwise specified. Guidance on the use of other conditions is provided in ETSI TS 136 521-1.

For each operating frequency band of the UE, measurements are conducted at appropriate frequencies 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 standard are as follows:

• The measured value is related to the corresponding limit used to determine whether the equipment meets the standard requirements;
• The measurement uncertainty value for each parameter must be included in the measurement report;
• For each measurement, the recorded measurement uncertainty value must be less than or equal to the values given in Tables 17 and 18. According to this standard, in measurement methods, the measurement uncertainty values must be calculated and must correspond to the expansion factor (coverage factor) k = 1.96 (for a confidence level of 95% in cases where the measurement uncertainty distributions are typically Gaussian). Principles for calculating measurement uncertainty are presented in ETSI TR 100 028, with special cases in Appendix C of ETSI TR 100 028-2. Guidance on the use of other measurement conditions is provided in ETSI TS 136 521-1.

Table 17- Maximum measurement system uncertainty

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

NOTE 1: For RF measurements, it should be noted that the uncertainties in Table 17 apply to the measurement system operating with a nominal 50 Ω load and do not account for effects due to mismatch between the EUT and the measurement system.

NOTE 2: If the measurement system has a measurement uncertainty greater than the measurement uncertainty specified in Table 17, the equipment may still be used, provided that adjustments are made as follows: Any additional measurement uncertainty in the measurement system beyond that specified in Table 17 can be used to tighten the measurement requirements – making the measurements harder to pass (for some measurements, such as receiver measurements, this may require changing the stimulus signals). This procedure ensures that a measurement system not meeting the requirements in Table 17 will not increase the likelihood of the EUT passing the measurements if it would have been deemed non-compliant if using a measurement system meeting the requirements in Table 17.

1) SS sends scheduling information for each UL HARQ process through PDCCH DCI format N0 for C_RNTI to arrange for UL RMC according to Table 6.2.2F.1.4.1-1 of ETSI TS 136 521-1. Since the UE has no load and no loop data to send, the UE sends MAC padding bits on the UL RMC (the UE must be ready to transmit P_Wanted after initial conditions have been established).

2) Measure the average power of the UE within the channel bandwidth of the radio access mode. The measurement time must be at least a continuous subframe period (1_ms) for subcarrier spacing 15 kHz or a slot (2 ms) excluding the 2 304 Ts gap when the UE does not transmit for subcarrier spacing 3,75 kHz. Guard subframes are not measured.

NOTE:     For configuration IDs applicable to the UE depending on the measurement configuration table with different UL subcarrier spacings, SS releases the connection through state 3A-NB and responds to the optimized CP CioT system in state 2A-NB according to Clause 8.1.5 of TS 136 508 using the appropriate UL subcarrier spacing in the random access response message.

3.3.14.False Emission

1. Measurement method

If possible, the measurement position should be a fully anechoic chamber to simulate free space conditions. EUT must be placed on a non-conductive stand. The average power of any false emission component must be determined by the measurement antenna and receiver (for example, spectrum analyzer).

At each frequency at which a component is identified, EUT must be rotated to achieve maximum response, and the effective radiated power (e.r.p) of that component is determined by an alternative measurement, which is the reference method. The measurement must be repeated with the measurement antenna in the orthogonal polarization plane.

NOTE: Effective radiated power (e.r.p) refers to the radiation of a half-wave dipole antenna instead of an isotropic antenna. The constant difference between e.i.r.p and e.r.p is 2.15 dB.

e.r.p (dBm) = e.i.r.p (dBm) - 2.15

(ITU-R SM.329-12 Recommendation, Appendix 1).

Measurements are performed with a half-wave dipole antenna or a reference antenna with known gain referenced to an isotropic antenna.

It must be stated in the measurement report if a different measurement position or measurement method is used. The results must be converted to the reference method values and the validity of the conversion must be demonstrated.

1. Measurement configuration

This section specifies the following measurement configurations for emissions testing:

- The equipment must be tested under normal measurement conditions;

- The measurement configuration must be as close as possible to the typical usage configuration;

- If the equipment is part of a system or can be connected to auxiliary equipment, testing the equipment when it is connected to the minimum configuration of auxiliary equipment to test ports is acceptable;

- If the equipment has many ports, enough ports must be selected to simulate actual operating conditions and ensure that all different types of port terminations are tested;

- Measurement conditions, measurement configurations, and operational modes must be recorded in the measurement report;

- Ports that are connected during normal operation must be connected to auxiliary equipment or representative cables terminated correctly to simulate the input/output characteristics of the auxiliary equipment, RF input/output ports must be terminated correctly;

- Ports that are not connected to cables during normal operation, such as service connectors, programming connectors, temporary connectors... must not be connected to any cable during testing. If cables need to be connected to these ports or cables need to be extended to run EUT, care must be taken to ensure that the evaluation of EUT is not affected by adding and extending these cables.

Emissions testing must be conducted in two operational modes:

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

- Idle mode.

3.3.15.Control and Monitoring Function

1) When starting the measurement, the UE must be turned off. The UE's antenna connector must be connected to a power meter with the following characteristics:

- The RF bandwidth must be greater than the total operating frequency band of the UE;

- The power meter's response time must ensure that the measured power does not exceed 1 dB from the steady-state power measurement within 100 μs when a CW signal is applied.

- This device must record the maximum measured power.

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

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

3) EUT must remain off for at least 30 seconds, then turned on for approximately 1 minute.

4) Record the maximum radiated power from the UE throughout the measurement period.
