1. TECHNICAL REGULATIONS

   1. Environmental profile

Technical requirements of this standard apply under the operating environmental conditions published by the manufacturer. The equipment must comply with these technical requirements when operating within the limits of the declared environmental conditions.

Appendix B includes the environmental conditions to be published.

1. General Requirements

The equipment manufacturer must publish:

• Operating frequency band of the base station.

• Supported RF configurations.

For base stations supporting multiple operating frequency bands, the testing specified in Section 3 of this standard must be conducted for each frequency band.

For base stations configured to receive multiple carriers, the BER ratio requirements must be applied to each received carrier. As for ACS characteristics, blocking and penetration
The noise signal offset below must be relative to the lower frequency band boundary, and the positive offset of the noise signal must be relative to the upper frequency band boundary of the base station.

For multi-band base stations, the technical requirements in this standard shall apply to each operating band, unless otherwise specified. In some cases, additional or removed requirements may be specified when applied to multi-band base stations.

For multi-band base stations that are a combination of different transmitter/receiver units (multi-band or single-band) mapped to one or more antenna ports in different ways, if the bands are transmitted on separate antennas then:

• Measure false receiver emission, modulation crossover of the transmitter, false transmitter emission, emission mask, single-band ACLR at each antenna port.

• If the base station is configured for single-band operation, the single-band requirements will apply to the single-band configured antenna port and apply to both single-band and multi-band base stations. Single-band requirements are measured and evaluated independently at each single-band configured antenna port while all other antenna ports are terminated.

The base station may transmit adjacent or non-adjacent spectra; however, the requirements in this standard will apply to base stations configured for adjacent and non-adjacent spectrum transmission unless otherwise specified.

For a base station operating with non-adjacent spectra, certain requirements apply within the protection band of component blocks. Each requirement will specify limit values for the component block boundaries.

Technical requirements apply to base station configurations specified in Appendix A of this standard.

For ACS measurements, blocking and modulation crossover characteristics, the negative offsets of the noise signal relative to the assigned channel frequency of the lowest carrier frequency received and the positive offsets of the noise signal relative to the assigned channel frequency of the highest carrier frequency received.

UTRA is designed with configurations as follows:

Non-adjacent spectrum UTRA configurations:

2.3. Emission Mask

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:

Out-of-band emissions are unwanted emissions generated during modulation and due to nonlinear effects in the transmitter, which lie immediately outside the channel bandwidth. The limits of out-of-band emissions are defined through the emission mask and the adjacent channel leakage ratio of the transmitter.

1. Limit

These requirements apply to any base station configured according to the manufacturer's specifications. For base stations operating non-adjacent spectra, these requirements apply within any protection band between component blocks. For multi-band base stations, these requirements apply within any protection band between radio frequency bands.

For multi-band base stations, where each band is transmitted on separate antennas, measurements and evaluations are conducted according to single-band requirements without cumulative requirements for emission limits within the protection band between radio frequency bands.

Emissions must not exceed the values specified in Tables 7 to 13 corresponding to the maximum output power of the base station, in the frequency range from Af = 2.5 MHz to Af._max relative to the carrier frequency, where:

• Af is the distance between the carrier frequency and the -3 dB reference point of the closest measurement filter.

• Frequency offset (f_offset) is the distance between the carrier frequency and the center frequency of the measurement filter.

• Maximum frequency offset (f_offsetmax) is the larger of two values: 12.5 MHz or the offset from the UMTS transmission band edge as specified in Section 1.1 of this standard.

• Amax equals f_offsetmax minus half the bandwidth of the measurement filter.

For multi-band base stations with a protection band between radio frequency bands smaller than 20 MHz, emissions within any such protection band must not exceed the cumulative sum of the limits specified at the radio frequency band edges of the base station on each side of the protection band between radio frequency bands. Limits for the band edges are specified in Tables 7 to 13, where:

• Af is 2.5 MHz plus the frequency difference between the radio frequency band edge and the -3 dB reference point of the closest measurement filter.

• f_offset is 2.5 MHz plus the frequency difference between the radio frequency band edge and the center frequency of the measurement filter.

• f_offsetmax is the larger of two values: 12.5 MHz or the offset from the UMTS transmission band edge.

• Af_max equals f_offset_max minus half the bandwidth of the measurement filter.

For multi-carrier base stations (BS), where multiple frequency bands are mapped onto the same antenna port, the limits on unwanted emissions apply within an operational band that supports carrier frequencies but does not have any carriers transmitted. In cases where there are carriers being transmitted in other supported operational bands, non-cumulative limits apply within the inter-band protection band between a supported downlink operational band and the carriers being transmitted, and another supported downlink operational band outside any transmitting carriers and:

• In the case where the inter-band protection band between a supported downlink operational band and the carriers being transmitted and a supported downlink operational band without any carriers being transmitted is less than 20 MHz, f_offset_max is the frequency offset of 10 MHz from outside the outermost edges of the two supported downlink operational bands and the limit on unwanted emissions in the operational band with carriers being transmitted is defined in the tables below and must be applied to both downlink operational bands. ■ '

In other cases, the limit on unwanted emissions in the operational band with carriers being transmitted must be applied from 10 MHz below the lowest frequency to 10 MHz above the highest frequency of the supported downlink operational band without any carriers being transmitted.

• Additionally, within the component block protection band for a base station operating on non-contiguous spectrum, measurement results shall not exceed the cumulative total of the limits specified for adjacent component blocks on each side of the component block protection band. The limits for each component block are specified in Tables 7 to 13, wherein:

Af equals 2.5 MHz plus the frequency interval between the edge frequency of the component block and the -3 dB reference point of the measurement filter near the edge frequency of the component block.

• f_offset equals 2.5 MHz plus the frequency interval between the edge frequency of the component block and the center frequency of the measurement filter.

• f_offsetmax equals half the component block protection band plus 2.5 MHz.

• Table 7 - Mask values, maximum output power of BS: p > 43 dBm

• Af_max equals f_offset_max minus half the bandwidth of the measurement filter.

Party 10 - Emission mask value, maximum output power of DS: p < 31 dBm

For base stations operating in V mode, they must comply with the requirements specified in Table 11.

Table 11 - Emission spectrum limits for base stations operating in V mode

For indoor BSs, in addition to the requirements specified in Tables 7 to 11, they must also comply with the requirements of Tables 12 and 13.

Table 13 - Emission mask values for indoor BSs, maximum output power of BS: p < 6 dBm

1. Measurement method

Use the measurements defined in Point 3.3.2 of this standard.

1. Adjacent Channel Leakage Ratio (ACLR)

   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:

The Adjacent Channel Leakage Ratio (ACLR) is the ratio between the average power of the RRC filtered signal centered on the assigned channel frequency and the average power of the RRC filtered signal centered on the adjacent channel frequency.

These requirements apply outside the edge of the bandwidth or the largest edge of any single-carrier or multi-carrier transmitter. This requirement applies to all types of transmission.

For base stations operating in non-contiguous bands, the ACLR requirements also apply to the first adjacent channel within any component block protection bandwidth greater than 15 MHz. The ACLR requirement for the second adjacent channel must apply within any component block protection bandwidth greater than 20 MHz.

For multi-band base stations and bands mapped to the same antenna port, the ACLR requirement must apply to the first adjacent channel within any RF band protection bandwidth if the protection bandwidth exceeds 15 MHz. If the protection bandwidth exceeds 20 MHz, the ACLR requirement applies to the second adjacent channel within any RF band protection bandwidth.

1. Limit

For wide-area type A base stations, ACLR compliance is either -13 dBm/MHz or the values specified in the tables below, whichever is less stringent.

For wide-area type B base stations, ACLR compliance is either -15 dBm/MHz or the values specified in the tables below, whichever is less stringent.

For medium-range base stations, ACLR compliance is either -25 dBm/MHz or the values specified in the tables below, whichever is less stringent.

For local base stations, ACLR compliance is either -32 dBm/MHz or the values specified in the tables below, whichever is less stringent.

The measurement results at Step 1 of Point 3.3.3.2 shall not exceed the ACLR limits specified in Table 14.

The measurement results at step 4 of Section 3.3.3.2 shall not exceed the ACLR limit specified in Table 15.

2.4.3. Cumulative ACLR limits for base stations operating in multi-band or non-contiguous spectrum

The following measurement requirements shall apply to BS transmitting in non-contiguous spectrum or multi-band.

With the guard band specified in Table 16, the following requirements must be applied:

• Within the guard band of the component block for BS operating in non-contiguous spectrum

• Within the guard band between bands for BS operating in multi-band and bands mapped to the same antenna port

The cumulative adjacent channel power ratio within the guard band of the component block or the guard band between bands is the ratio:

• The total average power filtered around the center frequency assigned to both adjacent carriers on each side of the component block or the guard band between bands.

• The average power filtered around the center frequency of the adjacent channel carrier with one of the edges of the component block or bandwidth.

The filtering parameters for the adjacent channel frequency are defined in Tables 16 and 17.

For wide-area Class A base stations, CACLR complies with either -13 dBm/MHz or the values specified in Table 16, whichever is less stringent.

For wide-area Class B base stations, CACLR complies with either -15 dBm/MHz or the values specified in Table 16, whichever is less stringent.

For mid-area base stations, CACLR complies with either -25 dBm/MHz or the values specified in Table 16, whichever is less stringent.

For local base stations, CACLR complies with either -32 dBm/MHz or the values specified in Table 16, whichever is less stringent.

For UTRA carriers located on or off the guard band of the component block or the guard band between bands, CACLR must be greater than the values specified in Table 16.

2.4.4. Measurement methods

Use the measurements prescribed in Section 3.3.3 of this standard.

1. Spurious emissions of the transmitter

   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:

Spurious emissions are unwanted emissions generated by the transmitter such as harmonic emissions, parasitic emissions, modulation products, and frequency conversion products, excluding out-of-band emissions. This value is measured at the RF output port of the base station.

Spurious emissions of the transmitter are determined within a frequency range narrower than 12.5 MHz from the first carrier frequency or wider than 12.5 MHz from the last carrier frequency used by the BS.

The requirements of Section 2.5.2 shall apply to all types of transmitters (single-carrier or multi-carrier). These requirements apply to all selected transmission modes that comply with the technical specifications of the manufacturer.

For multi-band base stations where the bands are mapped to the same antenna port, the spurious emission requirements (except those specified in Table 18 and Table 19) shall apply to frequencies within the specified range except for frequencies less than 12.5 MHz from the first carrier frequency or more than 12.5 MHz from the last carrier frequency used by the BS. For multi-band base stations where the bands are mapped to separate antenna ports, the spurious emissions of the transmitter shall be applied similarly to single-band transmitters.

All requirements shall be measured using average power, unless otherwise specified.

Transmitted modulation products_max The transmitted modulation product criterion measures the ability of the transmitter to eliminate signal formation in the nonlinear parts of the transmitter due to the presence of the desired signal and interfering signals at the transmitter antenna port.

The transmitted modulation product level is the power of the modulation products when an interfering WCDMA signal appears at the antenna port with an average power level lower than 30 dB compared to the average power level of the desired signal.

1. For multi-band base stations where these bands map to separate antenna connectors, single-band requirements will apply regardless of the position of the interfering signals relative to the inter-band protection bandwidth.

For multi-carrier base stations, the interference signal offset is determined by the upper/lower edge of the desired signal or the edge of the component block within the protection bandwidth.

For base stations transmitting non-contiguous spectrum, this requirement also applies to the interference signal offsets within the guard band of the component block when the interfering signal falls entirely within the guard band of the component block. The interference signal offset is determined relative to the edges of the component block.

When BS transmits multi-carrier signals, if the noise signal falls entirely within the RF frequency band interval, this requirement will also apply to the noise signal deviation within the protection band component interval. The noise signal deviation is determined through the bandwidth edges.

Requirements for out-of-band emission measurements or false emissions due to intermodulation can be limited by the frequency ranges of all third-order and fifth-order intermodulation products, the width of the intermodulation products, and without considering the desired signal bandwidth and noise signals.

• CPICH Ec (dBm) is the coding power of the primary CPICH on one of the existing adjacent channels at the antenna port of the indoor BS for the CPICH received on the adjacent channels. If transmit diversity is applied on the primary CPICH, CPICH Ec equals the sum (W) of the coding powers of the primary CPICH transmitted from each antenna.

• Loh (dBm) is the total received power, including signals and noise but excluding the signals of the indoor BS itself at the antenna port of the indoor BS on the active channel.

Input conditions for the requirements in this section are defined at the antenna port of the indoor BS.

1. MEASUREMENT METHODS

   1. Measurement conditions

Measurements in this standard must be conducted at characteristic points within the operational environmental condition boundaries.

At measurement points where technical criteria are susceptible to changes due to environmental conditions, tests must be performed under diverse environmental conditions (within the operational environmental condition boundaries) to verify compliance with affected technical requirements.

Generally, all tests must be conducted under normal measurement conditions unless otherwise specified.

The measurement system for each test is specified in Appendix C.

1. Interpretation of measurement results

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

• The measurement results relate to the threshold level used to determine whether the equipment meets the standard requirements.

• The measured uncertainty value for each parameter must be included in the measurement report.

• For each measurement, the recorded value of the measured uncertainty must be less than or equal to the value given in Table 47.

According to this Standard, the values of measurement uncertainty must be calculated and must correspond to a coverage factor k = 1.96 or K = 2 (this factor specifies a confidence level of 95% and 95.45% for cases where the distributions characterizing the actual measurement uncertainty are normal (Gaussian)). The principle of calculating measurement uncertainty follows Appendix D of TR 100 028-2.

NOTE 1: For RF measurements, the measurement uncertainty in the table above applies to the measurement system operating with a nominal load impedance of 50 ohms and not taking into account the effects of the system due to impedance matching between the Equipment Under Test (EUT) and the measurement system.

NOTE 2: If the measurement system has a measurement uncertainty greater than the measurement uncertainty specified in Table 47, then this equipment may still be used if the following adjustments are made:

The measurement uncertainty in the measurement system exceeding that specified in Table 47 is used to tighten the measurement requirements to make the measurements pass more easily (for some measurements such as receiver testing, this may require changes to the stimulus signals).

Fuw = ± (n X 1 MHz),

Where n must be increased sequentially from n = 10 until the center frequency of the interference signal covers the range from 1 MHz to 12.75 GHz. The interference signal level measured at the antenna connector must be set based on the center frequency of the signal, as specified in Tables 28 to 33. The type of interference signal or equivalent to a continuous WCDMA signal with a chip rate of 3.84 Mcps, filtered by an RRC pulse-shaping filter with roll-off factor a = 0.22, or a cw signal.

For narrowband operation, the GMSK-modulated interference signal has a minimum ACLR of 72 dB to minimize the adjacent channel power leakage impact on the modulation transmission testing.

3.3.13. Spurious Emission Measurement

1. Measurement Method

1. The measurement position must fully meet the requirements of ITU-R SM.329-12 Recommendation. The equipment under test (EUT) must be placed on a non-conductive stand and powered through an RF filter to limit radiation from electrical cables.

The average power of any spurious emission component must be detected by the measurement antenna and receiver (e.g., a spectrum analyzer). At each frequency of the detected emission, the effective radiated power (ERP) of the spurious emission component is determined by an alternative measurement, adjusting the height of the measurement antenna and rotating the EUT to obtain maximum response. The measurement must be repeated with the measurement antenna in the orthogonal polarization plane.

NOTE: Effective Radiated Power (E.R.P) is the radiation of a half-wave dipole antenna adjusted instead of an isotropic antenna. The conversion factor between e.i.r.p and E.R.P is 2.15 dB.

E.R.P (dBm) = e.i.r.p. (dBm) - 2.15

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

1. The base station must transmit at the maximum power specified by the manufacturer with all transmitters operating. The main station should be set up to transmit a signal as prescribed in the measurement of false emissions.

In the case of a repeater, the gain and output power must be adjusted to achieve the maximum values as published by the manufacturer. Use the input signal as prescribed
in the measurement of false emissions.

1. The video bandwidth must be approximately three times the channel bandwidth. If this video bandwidth is not available on the receiving measuring equipment, it must be adjusted to the maximum possible value and must be at least 1 MHz. Except in special cases, all measurements must be conducted with average power. The received power will be measured over the frequency bands and using the measurement bandwidth specified in Table 46.

   1. Measurement configurations

This section defines the configurations for measuring emissions as follows:

• Equipment must be tested under normal measurement conditions as specified.

• The measurement configuration should be as close as possible to the typical usage configuration.

• If the equipment is part of a system or connected to a system through auxiliary equipment, it may be tested when connected to the minimum configuration of auxiliary equipment necessary to test the ports.

• If the equipment has multiple ports, enough ports must be selected to simulate actual operating conditions and ensure that all different end connections are tested.

• The measurement conditions, measurement configurations, and operating modes must be recorded in the measurement report.

• Normally operating ports are connected to auxiliary equipment or a cable to simulate the input/output characteristics of the auxiliary equipment, the radio frequency (RF) input/output ports are accurately terminated.

• For normally operating ports not connected to cables, such as programming connectors, temporary connectors. These ports must not be connected to any cables for testing purposes. When cables are connected to these ports or required cables must be extended for testing the EUT, it must be ensured that the testing does not affect the evaluation of the EUT due to the addition or extension of these cables.

For an EUT containing multiple base stations, only the measurement of the typical base station connectors of the EUT is required.

Testing can be performed on separate auxiliary equipment or on a typical configuration of a combination of radio equipment and auxiliary equipment. In this case, the EUT is tested according to the emission requirements of this standard, and auxiliary equipment may be used with other radio equipment.

Product Name, Goods According to QCVN

Main Station Configuration

A.1. Receiver Channels

For the tests specified in Section 3 of this standard, the designated test signals must be directed to an antenna connector of the receiver, with the remaining receivers disabled or their antenna connectors terminated with a nominal 50 Ω load.

A.2. Duplexers

The requirements of this standard must be met with an appropriate duplexer, if a duplexer is provided as part of the base station. If the duplexer is provided by the manufacturer as an option, full tests must be repeated both with and without the appropriate duplexer to determine whether the base station meets the requirements of this standard in both cases.

The following tests must be performed with an appropriate duplexer, and without an appropriate duplexer if the duplexer is optional:

1. Article 3.3.5 Maximum output power of the base station, only for the highest static power level, if measured at the antenna connector.

2. Article 3.3.4 Out-of-band RF emission spectra of the BS.

3. Article 3.3.6 Modulation transmission measurements for compliance testing, carrier frequencies must be selected to minimize out-of-band modulation components from the transmitter falling into receiving channels. The remaining measurements may be performed with or without appropriate combiners.

NOTE 1: When performing receiver measurements with an appropriate combiner, it is important to ensure that the output from the transmitter does not affect the measurement equipment. A combination of attenuators, isolators, and filters can be used to achieve this.

NOTE 2: When using combiners, out-of-band modulation components are generated not only within the combiner but also within the antenna system. Out-of-band modulation components generated within the antenna system are not subject to technical requirements and may degrade over time (e.g., due to moisture ingress). Therefore, to ensure continuous operation of the base station, operators typically select UARFCNs to minimize out-of-band modulation components falling into receiving channels. Operators may set up the required UARFCNs for comprehensive testing.

A.3. Power Supply Options

If the BS has multiple types of power supply configurations, it is not necessary to test RF parameters for each type of power supply provided that the range of conditions on the tested equipment is proven to be equivalent to the range of conditions of any power supply configuration.

Specifically, for a base station with a single DC rail powered either externally or internally, when the internal power supply configuration is being tested, it can be done by testing with an external DC power supply. The range of DC input voltages for testing must be sufficient to verify the quality of any power supply outside the operational range of the base station, including variations in input voltage, temperature, and output current.

A.4. Auxiliary RF Amplifiers

The requirements of this standard must be met with suitable auxiliary RF amplifiers. For the corresponding transmit and receive tests under Section 3, the auxiliary amplifier is connected to the BS through network elements (such as cables, attenuators) with appropriate attenuation to avoid affecting the operation of the auxiliary amplifier itself
as well as the base station. The range of appropriate attenuation of the connecting network elements is published by the manufacturer. Other characteristics dependent on the attenuation of the connecting network elements are disregarded. The actual attenuation value of the connecting network elements chosen for each test is one of the limit values applied. The lowest value is used if no other provision is made.

Some test procedures may be repeated with or without the auxiliary RF amplifier, if the auxiliary RF amplifier is optional, to check whether the base station meets the requirements of the standard in both cases.

During testing, the tests listed in Table A.1 below must be repeated with the auxiliary amplifier, where X is specified to be carried out:

NOTE: The combination may be due to combiners or any other network. The amplifiers may be in the receive branch or in the transmit branch or in both branches. One of these amplifiers may be a passive network.

In the testing at 3.3.5, the largest appropriate attenuation value is applied.

A.5. BS Using Antenna Arrays

A BS may be configured to connect antenna ports to one or more transceivers or an antenna array associated with a cell (not an array for each transceiver). This section applies to a BS meeting at least one of the following conditions:

• Transmit signals from one or more transceivers appear at multiple antenna ports or

• There are multiple receive antenna ports for one transceiver or for each cell, and a signal input is required at multiple ports for the receiver to function correctly, thus the outputs from the transmitters as well as the inputs to the receivers are directly connected to several antennas or

NOTE: Diversity reception does not meet this requirement.

• The transmitters and receivers are connected via combiners to multiple antennas. In normal operation, if a BS is used with an antenna system having filters or active elements necessary to meet UTRA requirements, testing can be conducted on a system comprising the BS together with these elements. In this case, it must be demonstrated that the configuration being tested is representative of the system in normal operation, and compliance evaluation can only be applied when using the BS with the antenna system.

A.5.1 Receiver Testing

For each test, the measured signals delivered to the receiver antenna connectors must be large enough so that the total power of the input signals equals the power of the (specified) test signals.

Figure A.1 - Receiver testing setup

For emissions from the receiver antenna connectors, separate measurements can be performed for each receiver antenna connector.

A.5.2 Transmitter Testing

For each test, the measured signals at the transmitter antenna connectors (Pi) must be large enough so that the total power of the input signals equals the power of the (specified) test signals (P). Separate measurements can be made for each signal emitted from every antenna connector and the results combined, or the signals can be combined and a single measurement performed. The characteristics (e.g., amplitude and phase) of the combined network must meet the maximum power of the combined signal._{CLASS MONOCOTYLEDON}An example of a test configuration is shown in Figure A.2.

A.6. Diversity Transmission and MIMO

A.6. Multi-carrier transmission and MIMO

The measurements prescribed in the standard shall be carried out on each antenna port when transmitting DB-DC-HSDPA or MIMO streams, with different connectors terminated. If the manufacturer declares that all antenna outputs are equivalent, then only one arbitrary port needs to be tested.

Transmitters shall be measured at the antenna port with other connectors terminated. When the manufacturer announces that all antenna outputs are equivalent, testing may be conducted at any single port.
