2.2.4. Maximum Output Power

2.2.2.1. Definition

Unwanted emissions include out-of-band emissions and spurious emissions. Out-of-band emissions are emissions outside the channel bandwidth caused by modulation processes and non-linearities in the transmitter, excluding spurious emissions. Spurious emissions are emissions generated by unwanted effects of the transmitter such as harmonic emissions, parasitic emissions, intermodulation components, and frequency conversion components, but excluding out-of-band emissions. Spurious emissions are measured at the output port of the relay station.

The out-of-band emission requirements for the repeater station equipment include both unwanted emissions outside the band and protection for the base station receiver within the operating frequency band. Unwanted emissions within the operating band are defined as all unwanted emissions within the operating band of the repeater station equipment, plus a 10 MHz bandwidth below and above it. Unwanted emissions outside this range are limited to the spurious emission requirements.

2.2.2.2. Limits

- ∆f is the distance from the edge frequency of the nominal passband and the -3 dB point of the nearest measured filter to the carrier frequency.

- The nominal passband width is the lowest and highest frequencies of the repeater station equipment's passband.

- BW_Meas is the measured bandwidth.

- BW_{"5. The pre-tax weighted average cost of capital i (%) is determined according to the formula below:Ass Band} is the bandwidth of the repeater station equipment's passband.

- f_offset is the deviation from the edge frequency of the nominal passband to the center of the measured filter.

- f_offset_max is the frequency deviation f_offset of the frequency outside 10 MHz relative to the operating band of the repeater station equipment.

- ∆f_max equals f_offset_max minus half the bandwidth of the measured filter.

All requirements are measured using average power (RMS).

These requirements apply to both uplink and downlink, with maximum gain and input signals as follows:

- No E-UTRA FDD input signal;

- An E-UTRA FDD input signal within the repeater station equipment's passband at the level that produces the maximum rated output power for each channel;

- A 10 dB increase in the E-UTRA FDD input signal across all channels within the passband compared to the level producing the maximum rated output power.

3. MEASUREMENT METHODS

3.3. Measurement of Essential Parameters for the Radio Access Part

The measurements defined in this standard must be performed at representative points within the boundaries of the declared operational environmental conditions.

At points where technical parameters vary depending on environmental conditions, measurements must be conducted under sufficient types of environmental conditions (within the boundaries of the declared operational environmental conditions) to verify compliance with affected technical requirements.

Generally, measurements only need to be carried out under normal measurement conditions unless otherwise specified.

The measurement system diagrams specified for each measurement are described in Appendix C.

3.3.1. Unwanted Emissions in Operating Band

The results recorded in the measurement report for the measurements described in this standard must be explained as follows:

- Measured values related to corresponding limits will be used to determine whether the equipment meets the requirements of the standard;

- Measurement uncertainty values for each parameter must be included in the measurement report;

- For each measurement, the recorded value of measurement uncertainty must be equal to or less than the values specified in Tables 20.

According to this standard, for measurement methods, measurement uncertainty values must be calculated according to TR 100 028 and must correspond to the expansion factor (coverage factor) k = 1.96 (this factor specifies a confidence level of 95% in cases where actual measurement uncertainty distributions are typically Gaussian).

ANNEX A (Provisions) Forms of Mobile Base Station Repeater Equipment

3.3.8.1. Measurement Method

1) The measurement position must comply with the requirements of ITU-R Recommendation SM.329-10. The EUT must be placed on a non-conductive stand and operated from a power supply through an RF filter to avoid radiation from electrical wires.

The average power of every spurious component must be separated by the test antenna and receiver (e.g., spectrum analyzer). At each frequency where the component is separated, the EUT must be rotated and the height of the test antenna adjusted to obtain the maximum response curve and the Effective Radiated Power (ERP) of that component determined by substitution measurement. The measurement must be repeated with the test antenna in the orthogonal polarization plane.

NOTE: The Effective Radiated Power (ERP) is related to the radiation of a half-wave dipole instead of an omnidirectional antenna. The constant difference between e.i.r.p and ERP is 2.15 dB (ITU-R Recommendation SM.329, Appendix 1).

ERP (dBm) = e.i.r.p (dBm) - 2.15 (ITU-R Recommendation SM.329, Appendix 1).

2) The BS must transmit at the maximum power declared by the manufacturer with all transmitters operating.

Set up the base station to transmit signals as indicated in the applicable section for measuring false emissions.

In the case of repeater equipment, the gain and output power must be adjusted to the maximum value as declared by the manufacturer. Use the input signal as indicated in the applicable section for measuring false emissions.

3) The video bandwidth must approximately equal three times the resolution bandwidth. If this video bandwidth is not available in the receiver, it must have the maximum value and be at least 1 MHz.

3.3.8.2. Measurement Configuration

This specifies the configurations for emission measurements as follows:

- Equipment must be tested under normal measurement conditions as specified in functional standards;

- Measurement configurations should be as close to typical usage as possible;

- If the equipment is part of a system or can be connected to auxiliary devices, it may be acceptable to test the equipment when connected to the minimum configuration of auxiliary devices necessary for port usage;

- If the equipment has multiple ports, enough ports must be selected to simulate actual operating conditions and ensure that all types of terminal devices are tested;

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

- Ports connected during normal operation must be connected to auxiliary devices or representative cables in the correct manner to simulate the input/output characteristics of the auxiliary devices. Radio Frequency (RF) input/output ports must be terminated correctly;

- Ports not connected to cables during normal operation, such as service connectors, programming connectors, temporary connectors, etc., must not be connected to any cables used for these measurements. Where cables must be connected to these ports, or where cables linking must be extended for EUT use, precautions must be taken so that EUT evaluation is not affected by the addition or extension of these cables.

For EUTs containing multiple BSs, only tests related to the connections of each representative type of components forming the BS of the EUT need to be performed.

For EUTs containing multiple repeater units, only tests related to the connections of each representative type of components forming the repeater unit of the EUT need to be performed.

At the discretion of the manufacturer, testing may be conducted separately on auxiliary devices or on representative configurations of the radio equipment and auxiliary devices. In each case, the EUT is tested based on all applicable emission requirements of this standard, and in each case, compliance allows the auxiliary device to be used with other radio equipment.
