2.     TECHNICAL REGULATIONS

2.          

2.1.         Environmental conditions

The technical requirements of this regulation are applied under the operating environment conditions of the equipment announced by the manufacturer. Equipment must fully comply with all technical requirements of this regulation when operating within the boundary limits of the declared operating environmental conditions.

Appendix B guides suppliers on how to declare environmental conditions.

2.2.         Technical requirements

2.2.1.  General requirements

Device manufacturers must declare:

-       Base station operating bands;

-       Base station operating bands support carrier aggregation;

-       RF configurations are supported as specified in 4.6.8 of ETSI TS 136 141.

For base stations that support multiple operating bands, the testing specified in Article 3 of this regulation must be implemented on each frequency band.

For a BS with a multi-carrier reception configuration, all throughput requirements must be applied to each received carrier. For ACS, blocking, and intermodulation characteristics, the negative offsets of the interfering signal must be relative to the edge on the base station RF bandwidth.

For BSs capable of multi-band operation, the requirements in this regulation are applied to each operating band, unless otherwise specified. In some cases, it may be possible to specify additional or omitted requirements specifically applicable to this BS.

With a BS capable of multi-band operation, it is a combination of different (multi-band or single-band) transmitters/receivers and mapped to one or more antenna ports in different ways, if the bands are transmitted on separate antennas:

-       Test single-band ACLR, unwanted emissions in the operating band, transmitter spurious emissions, transmitter intermodulation and receiver spurious emissions applicable to each antenna connector;

-       If the BS is configured for single-band operation, the single-band requirements are applied to the antenna connector configured for single-band operation and also to the BS capable of multi-band operation. Single-band requirements are tested independently at an antenna connector configured for single-band operation, while all other antenna connectors are terminated.

For a BS capable of multi-band operation supporting bands for TDD, the RF requirements in this specification assume synchronous operation, where uplinks and downlinks do not occur simultaneously between bands supported operations.

The technical requirements applicable to BS configurations are specified in Appendix A.

2.2.2.        Unwanted radiation in the operating frequency band

2.2.2.1.      Definition

Unwanted emissions include out-of-band emissions and spurious emissions (Recommendation ITU-R SM.329-12). Out-of-band emissions are unwanted emissions (but do not include spurious emissions), located just outside the channel bandwidth, produced during the modulation process and due to the effects of nonlinearities in the transmitter. The limit of out-of-band emissions of the BS transmitter is determined according to the unwanted emissions in the operating band and the adjacent channel leakage power ratio (ACLR).

Limits for unwanted spurious emissions in the operating bands are specified from 10 MHz below the lowest frequency of each supported downlink operating band to 10 MHz above the highest frequency of each supported operating downlink band is supported (see Table 1).

The requirements are applied to all transmitter types (single carrier or multicarrier) and to all transmit modes selected in accordance with the manufacturer's specifications. Additionally, for a BS operating in multiple bands, these requirements are applied within the RF interband protection interval.

For BSs supporting multicarriers, the unwanted emission requirements are applied to outermost carrier channel bandwidths greater than or equal to 5 MHz.

For a multi-carrier E-UTRA BS configured for intra-band adjacent and non-adjacent carrier aggregation, the above definitions are applied to the lower edge of the transmitted carrier at the lowest carrier frequency and the upper edge of the transmitted carrier at the highest carrier frequency within the specified operating frequency band.

For BSs capable of multi-band operation, where multiple bands are mapped onto separate antenna connectors, single-band requirements are applied but not cumulative estimate of emission limits within the range applies RF interband protection.

2.2.2.2.      Limit

For wide coverage BSs, this requirement is applied to outside of the base station RF bandwidth. In addition, this requirement is also applied within any sub-block guard interval for a wide coverage BS operating in a non-adjacent spectrum and within any inter-RF bandwidth guard interval for a wide coverage BS operating in multiple frequency bands.

For medium coverage BSs, this requirement is applied to outside of the base station RF bandwidth. In addition, this requirement is applied within any sub-block guard interval for a medium coverage BS operating in a non-contiguous spectrum and within any inter-RF bandwidth guard interval for a medium coverage BS operating in multiple frequency bands.

For narrow-coverage BSs, this requirement is applied to outside of the base station's RF bandwidth. In addition, this requirement is applied within any sub-block guard interval for a narrow coverage BS operating in a non-contiguous spectrum and within any inter-RF bandwidth guard interval for a narrow coverage BS operating in multiple frequency bands.

Outside the base station RF bandwidth, emissions do not exceed the maximum levels specified in the Tables 3 to 13 and Table 14 to Table 19, in which:

-       Df is the distance between the channel edge frequency and the nominal -3 dB point of the measurement filter closest to the carrier frequency;

-       f_offset is the distance between the channel edge frequency and the center frequency of the measurement filter;

-       f_offset_max is the offset from the frequency 10 MHz outside the downlink operating band;

-       Df _max is equal to f_offset _max minus half the bandwidth of the measurement filter.

For a BS operating in multiple bands, within any inter-RF bandwidth guard interval with W_gap < 20 MHz, emissions shall not exceed the cumulative sum of the limits specified at the RF bandwidth edges of the base station on each edge of the RF interband guard interval. Limits for RF bandwidth edges are specified in Tables 3 to 5, in which:

-       Df is the distance between the base station RF bandwidth edge frequency and the nominal -3 dB point of the measurement filter closest to the base station RF bandwidth edge;

-       f_offset is the distance between the RF bandwidth edge frequency of the base station and the center frequency of the measurement filter;

-       f_offset _max is equal to the RF interband guard interval minus half the measurement filter bandwidth;

-       Df _max is equal to f_offset _max minus half the bandwidth of the measurement filter.

For BSs capable of multi-carrier operation, where multiple frequency bands are mapped onto the same antenna connector, the unwanted emission limits in the operating band also apply within a supported operating band within any transmitted carrier, in cases where there are transmitted carrier(s) in another supported operating band. In this case, the non-cumulative limit applies in the inter-band guard interval between a supported downlink operating band with the transmitted carrier(s) and an externally supported downlink operating band in addition to any transmitted carrier and:

-       In case the inter-band guard interval between a supported downlink operating band with the transmitted carrier(s) and a supported downlink operating band outside any transmitted carrier is less than 20 MHz, f_offset _max is the offset from the 10 MHz frequency beyond the outermost edges of the supported downlink operating bands and limits unwanted emissions within the operating band where the carriers are transmitted, specified in the tables of this clause, applied on both downlink frequency bands.

2.2.3.        Adjacent Channel Leakage Power Ratio (ACLR)

2.2.3.1.      Definition

Unwanted emissions include out-of-band emissions and spurious emissions. Out-of-band emissions are emissions that lie just outside the channel bandwidth, produced during the modulation process and due to the effects of nonlinearities in the transmitter. The limit of out-of-band emissions of the BS transmitter is determined according to the unwanted emissions in the operating band and the adjacent channel leakage power ratio (ACLR).

The adjacent channel leakage power ratio (ACLR) is the ratio of the filtered mean power centered on the assigned channel frequency to the RRC filtered mean power centered on the adjacent channel frequency.

This requirement applies beyond the base station RF bandwidth or maximum radio bandwidth to any type of transmitter (single carrier or multiple carrier) and to any transmit mode selected in accordance with the manufacturer's specifications. The interference signal offset is determined relative to the base station's RF bandwidth edges.

For a BS operating in a non-adjacent spectrum, ACLR applies to the first adjacent channel within any sub-block gap with guard gap size W_gap ≥ 15 MHz. The ACLR requirement applies to the second adjacent channel within the component block guard interval with size W_gap ≥ 20 MHz. The CACLR requirements specified in 2.2.3.2.2 apply within the component block protection interval with the frequency ranges specified in Table 20 for paired spectrum and Table 21 for unpaired spectrum.

For a BS operating in multiple bands, which are mapped to the same antenna connector, ACLR applies to the first adjacent channel within the RF interband guard interval with guard interval size W _gap ≥ 15 MHz. The ACLR requirement for the second adjacent channel applies within any RF interband guard interval with any guard interval size W_gap ≥ 20 MHz. The CACLR requirement in 2.2.3.2.2 applies in RF interband guard intervals with frequency bands as specified in Table 20 for paired spectrum and Table 21 for unpaired spectrum.

Requirements apply throughout the generator's ON cycle.

-       Within a guard interval blocks components in the operating band for BSs operating in non-adjacent spectrum;

-       Within an RF interband guard interval for the BS operating in multiple bands, where these bands are mapped onto the same antenna connector.

The cumulative adjacent channel leakage power ratio within a subblock guard interval or RF interband guard interval is the ratio of:

a)     The total filtered average power centered on the channel frequencies assigned to both adjacent carriers to each edge of the sub-block guard interval or RF inter-band guard interval; and

b)    The filtered average power is centered on a frequency channel adjacent to one of the component block edges or the base station RF bandwidth edges.

Assumed filters for adjacent channel frequencies are specified in Table 24 for paired spectrum and Table 25 for unpaired spectrum. The filters on the assigned channels are specified in Table 26.

2.2.6.1.      Definition

The transmit intermodulation index is a measure of the transmitter's ability to eliminate the formation of signals in the nonlinear elements of the transmitter due to the presence of wanted signals and interference signals through the transmitter antenna. This criterion applies throughout the generator ON cycle and generator transition cycle.

The transmit intermodulation level is the power of the intermodulation components when an E-UTRA modulated interfering signal of 5 MHz channel bandwidth is present at the antenna connector with an average power level 30 dB less than the average power of the wanted signal.

For BSs capable of multi-band operation, where multiple bands are mapped onto separate antenna connectors, single-band criteria apply regardless of the relative location of the interfering signals. compared to the RF bandwidth protection interval.

The desired signal is single carrier, multicarrier, or E-UTRA contiguous additive multicarrier, for both contiguous and nonadjacent spectrum operations.

The criteria is applied to all types of transmitters (single carrier or multicarrier) and all transmission methods declared by the manufacturer.

2.2.6.2.      Limit

The wanted signal channel bandwidth BW_Channel is the maximum channel bandwidth.

In the frequency range related to this requirement, the transmitter intermodulation level does not exceed the limit of unwanted emissions specified in 2.2.2.2 , 2.2.3.2 and 2.2.4.2 when there is an interfering signal according to specified in Table 31.

For BSs operating in discontinuous spectrum, this requirement is applied to interference signal deviations within the sub-block guard interval, when the interfering signal is completely inside the sub-block. Deviation of the specified interference signal compared to the component block boundaries.

For BSs capable of multi-band operation, this requirement is applied to the base station RF bandwidth boundaries for each supported operating band. In cases where the RF inter-band guard interval is less than 15 MHz, this requirement is only applied to interference signal deviations within the guard interval, when the interfering signal lies entirely within the inter-band interval RF gaurd.

This requirement is applied outside the base station RF bandwidth or peak radio bandwidth. Specified interference signal deviation from the base station RF bandwidth edges or maximum radio bandwidth.

Table 31 – Interference and wanted signals for transmitter intermodulation devices

Parameter	Value
Center frequency deviation of the interfering signal from the low/high edge of the wanted signal or the component block edge within the component block guard interval	±2.5 MHz ±7.5 MHz ±12.5 MHz
NOTE: This criterion excludes interference signal locations that are partially or completely outside the base station's downlink operating band, except for interference signal locations within the frequency range of the base station's operating bands neighboring downlink movements within the same limited area.

In case, the interfering signal locations do not apply the provisions in Table 31, a wanted signal channel BW_Channel smaller than the maximum channel bandwidth supported by the BS must satisfy that there is at least one location of the interference signal that meets the regulations in Table 31.

The measurement of the desired emission specification for intermodulation may be limited by the frequency ranges of all third- or fifth-order intermodulation products, taking into account the width of the intermodulation products. This does not include the wanted bandwidth and the interfering signal bandwidth.

2.2.6.3.      Measurement method

Use the tests specified in 3.3.5.

2.2.7.        Receiver spurious emissions

2.2.7.1.      Definition

The receiver spurious emission power is the power of the emissions generated or amplified in the receiver appearing at the antenna connector of the BS. The requirements below are applied to any BS with separate RX and TX antenna ports. Testing must be performed with both TX and RX enabled, with the TX port terminated.

For TDD BSs with common RX and TX antenna ports, these requirements are applied throughout the transmitter OFF cycle. For FDD BSs with common RX and TX antenna ports, the transmitter's spurious emission limits are specified in 2.2.4.

For BSs capable of multi-band operation, where multiple bands are mapped onto separate antenna connectors, the single-band requirements are applied and the omitted band applies only to the operating band supported on each antenna connector.

2.2.7.2.      Limit

The power of any spurious emission shall not exceed the limits specified in Table 32.

In addition to the requirements in Table 32, the power of any spurious emission must not exceed the provisions in 2.2.4.2.2 and 2.2.4.2.3.

Table 32 – Spurious emission measurement requirements

Frequency band	Extreme value	Measuring band width	Note
30 MHz to 1 GHz	-57 dBm	100 kHz
1 GHz to 12.75 GHz	-47 dBm	1MHz
NOTE: Subtract frequencies from 2.5 x BWChannel below the first carrier frequency to 2.5 x BWChannel above the last carrier frequency used by the BS transmitter, where BWChannel is the channel bandwidth specified in ETSI TS 136 141, table 5.6-1. Additionally, except for frequencies greater than 10 MHz below the lowest frequency of any supported downlink operating band or above the highest frequency of any supported downlink operating band (see Table 1). For BSs with multi-band capability, the removed frequency range applies to all supported operating bands. For BSs capable of multi-band operation, where multiple bands are mapped onto separate antenna connectors, the single-band and frequency range requirements are eliminated to apply only to the active band supported on each antenna connector.

2.2.8.  Blocking properties

2.2.8.1.      Definition

The blocking characteristics are a measure of the ability of a receiver to receive a wanted signal at its assigned channel frequency in the presence of unwanted interference at frequencies of 1.4 MHz, 3 MHz or 5 MHz of the E-UTRA signal for in-band blocking or CW signals for out-of-band blocking. E-UTRA interference signals are specified in Appendix C of ETSI TS 136 141.

2.2.8.2.      Limit

The throughput must be ≥ 95% of the maximum throughput of the reference measurement channel, with one wanted signal and one interfering signal coupled to the BS antenna input using the parameters specified in Table 36 and Tables 33, Table 34, Table 35 or Table 37, depending on the declared base station class and operating frequency band. The standard measurement channel for the wanted signal is the measurement channel for each channel bandwidth specified in Tables 7.2-1, 7.2-2, 7.2-2 or 7.2-4 of ETSI TS 136 141 depending on the base station class and regulations in Appendix A of ETSI TS 136 141.

Blocking requests apply outside the base station RF bandwidth or maximum radio bandwidth. Specified interference signal deviation from base station RF bandwidth edges and maximum radio bandwidth edges.

For a BS operating in a non-contiguous spectrum within any operating band, if the sub-block guard interval size is wider than or equal to twice the interference signal deviation in Table 36, adds a requirement that the blocking apply within any component block guard interval. Specified interference signal deviation from the component block boundaries within the component block guard interval.

For a BS capable of multi-band operation, the requirements in the in-band blocking frequency bands are applied to each supported operating band. If the interband RF guard interval size is wider than or equal to twice the interference signal offset in Table 36, an additional blocking requirement applies within any interband RF guard interval.

For a BS capable of multi-band operation, requirements in out-of-band blocking frequency bands are applied to each operating band. Out-of-band blocking requirements are not applied to in-band blocking frequency bands within the supported operating bands specified in Table 33, Table 34 and Table 37.

2.          

3.1.         Testing conditions

The tests specified in this regulation shall be performed at representative points within the boundary limits of the declared operating environmental conditions.

At points where specifications change depending on environmental conditions, tests must be performed under diverse environmental conditions (within the boundary limits of the operating environmental conditions declared) to check compliance with the affected technical requirements.

Normally all tests shall be carried out under normal test conditions unless otherwise specified. Reference can be made to Appendix B for the use of other test conditions to check compliance.

This section specifies the measurement methods for E-UTRA (FDD and TDD).

Test configurations and channel widths for multicarrier operations must be complied with the provisions of 4.10, 5.7.1 and 5.7.1A of ETSI TS 136 141.

Normally all tests should be performed with the lowest and highest bandwidth supported by the BS, unless otherwise specified. In case no testing is performed, the manufacturer must declare all other bandwidths supported by the BS.

In the case of a single carrier, multiple tests are performed with appropriate frequencies at the bottom, middle and top of the operating band of the BS. These frequencies are designated as B (bottom), M (middle) and T (start) of RF channels and are defined in 4.7 of ETSI TS 136 141.

In the case of single-band multicarriers, multiple tests are performed with the maximum base station RF bandwidth positions at the bottom, middle, and top of the supported frequency range in each operating band. These frequencies are designated B_RFBW (bottom), M_RFBW (middle) and T_RFBW (start) for non-additive channels and are defined in 4.7.1 of ETSI TS 136 141.  

In the dual-band case, multiple tests are performed with the base station RF bandwidths at the end of the supported frequency range in the lower operating band and at the top of the supported frequency range in the upper operating band. These frequencies are designated as B_RFBW _T'_RFBW and B'_RFBW _T_RFBW and are defined in 4.7.1 of ETSI TS 136 141.

The measurement system specified for each test is described in Annex C.

3.2.         Interpretation of measurement results

The results recorded in the test reports of the measurements specified in this Regulation must be explained 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 measurement uncertainty shall be less than or equal to the value given in Table 58.

According to this standard, in measurement methods, the values of measurement uncertainty must be calculated according to ETSI TR 100 028, specifically Annex D of ETSI TR 100 028-2 and must correspond to an expansion factor (coverage factor) k = 1.96 or k = 2 (this factor specifies a confidence level of 95% and 95.45% in the case of distributions that characterize the true measurement uncertainty is actually Gaussian)).

Table 58 is based on this expansion factor.

3.3.14.   Radiation radiation

3.3.14.1. Measurement method

1)    The test location must fully meet the requirements of Recommendation ITU-R SM.329-12. The device under test The EUT is placed on a non-conductive support and is powered through an RF filter to limit radiation from the electrical conductors.

The average power of any radiated component shall be detected by the test antenna and the measuring receiver (e.g. a spectrum analyser). At each frequency of the detected emission and the effective radiated power (ERP) of that emission component is determined by a surrogate measurement, adjust the height of the test antenna and rotate the EUT to obtain maximum response. The measurement shall be repeated with the test antenna in the orthogonal polarization plane.

NOTE: Effective radiated power (ERP) is the radiation of a corrected half wave by a dipole antenna instead of an isotropic antenna. The conversion factor between eirp and ERP is 2.15 dB

ERP (dBm) = eirp (dBm) - 2.15

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

2)    The BS must transmit at maximum capacity as announced by the manufacturer with all transmitters operating. Set up the base station to transmit a signal as specified in the measurement of spurious emissions section.

In the case of a repeater, the gain and output power shall be adjusted to the maximum value as declared by the manufacturer. Use the input signal as specified in the measurement of spurious emissions section.

3)    The video bandwidth should be approximately three times the resolution bandwidth. If this video bandwidth is not available on the measuring receiver, it shall be adjusted to the maximum possible and shall be at least 1 MHz. Except for special cases, all measurements shall be performed with average power. The received power will be measured across frequency bands and using the test bandwidth specified in Table 57.

3.3.14.2. Measurement configuration

This section defines the configurations for emission testing as follows:

-       The device must be tested under normal testing conditions as prescribed;

-       The test configuration should be as close as possible to the typical usage configuration;

-       If the device is part of a system or is connected to the system via a slave, the device can be tested while connected with the minimum slave configuration required to test the ports;

-       If the device has multiple ports, a sufficient number of ports must be selected to simulate real operating conditions and ensure that all different terminations are tested;

-       The test conditions, test configurations and operating modes shall be recorded in the test report;

-       operating ports are connected to a slave device or a cable segment to simulate the slave's input/output characteristics, the radio frequency (RF) input/output ports are terminated to the main body;

-       For normally functioning ports not connected to a cable, e.g. service connectors, programming connectors, temporary connectors. These ports must not be connected to any cables for testing purposes. When cables connecting to these ports or connecting cables are required to be extended in length for EUT testing, it must be ensured that EUT evaluation testing is not affected by the addition or extension of these cables.

For an EUT containing multiple BSs, it is necessary to perform tests only on the typical BS terminals of the EUT.

For EUT there are many repeater stations. It is only necessary to perform the test on the typical repeater terminal terminals of the EUT.

Depending on the manufacturer, testing may be performed on a separate slave device or on a typical configuration of a combination of radio and slave equipment. In each case, the EUT is tested in accordance with the emission provisions of this Regulation and allows the auxiliary equipment to be used with other radio equipment.
