6.6.4.4.2 Procedure
6.6.4.4.2.1 General procedure
The minimum requirement is applied to all TAB connectors, they may be tested one at a time or multiple TAB connectors may be tested in parallel as shown in clause D.1.1. Whichever method is used the procedure is repeated until all TAB connectors necessary to demonstrate conformance have been tested.
a) Connect TAB connector to measurement equipment as shown in clause D.1.1. All TAB connectors not under test shall be terminated.
As a general rule, the resolution bandwidth of the measuring equipment should be equal to the measurement bandwidth. However, to improve measurement accuracy, sensitivity, efficiency and avoiding e.g. carrier leakage, the resolution bandwidth may be smaller than the measurement bandwidth. When the resolution bandwidth is smaller than the measurement bandwidth, the result should be integrated over the measurement bandwidth in order to obtain the equivalent noise bandwidth of the measurement bandwidth.
The measurement device characteristics shall be:
– Measurements with an offset from the carrier centre frequency between 2,515 MHz and 4.0 MHz shall use a 30 kHz measurement bandwidth.
– Measurements with an offset from the carrier centre frequency between 4.0 MHz and (f_offsetmax – 500 kHz).shall use a 1 MHz measurement bandwidth.
– Detection mode: True RMS.
The emission power should be averaged over an appropriate time duration to ensure the measurement is within the measurement uncertainty in Table 4.1.2.2-1.
b) For single carrier operation set the TAB connector to transmit at manufacturers declared rated carrier output power per TAB connector (PRated,c,TABC)
For a TAB connector declared to be capable of multi-carrier and/or CA operation set the TAB connector to transmit on all carriers configured using the applicable test configuration and corresponding power setting specified in clause 5 using the corresponding test models or set of physical channels in clause 4.12.
6.6.4.4.2.1 UTRA FDD
1) Step the centre frequency of the measurement filter in contiguous steps and measure the emission within the specified frequency ranges with the specified measurement bandwidth. For multi-band TAB connector or TAB connector operating in non-contiguous spectrum, the emission within the Inter RF Bandwidth or sub-block gap shall be measured using the specified measurement bandwidth from the closest Base Station RF Bandwidth or sub block edge.
In addition, for multi-band TAB connector(s), the following steps shall apply:
2) For multi-band TAB connectors and single band tests, repeat the steps above per involved band where single band test configurations and test models shall apply with no carrier activated in the other band.
6.6.4.4.2.2 UTRA TDD
1) Measure the power of the TAB connector spectrum emissions by applying measurement filters with bandwidths as specified in the relevant table in clause 6.6.4.5.2.2. The characteristic of the filters shall be approximately Gaussian (typical spectrum analyzer filters). The centre frequency of the filter shall be stepped in contiguous steps over the ranges of frequency offsets f_offset as given in the tables. The step width shall be equal to the respective measurement bandwidth. The time duration of each step shall be sufficiently long to capture one active time slot.
2) The measurement shall be performed by applying filters with measurement bandwidth of 50 kHz or less and integrating the measured results over the nominal measurement bandwidth 1 MHz specified in the tables in clause 6.6.4.5.2.2 when the measurement bandwidth is 1 MHz.
In addition, for multi-band TAB connector(s), the following steps shall apply:
3) For multi-band TAB connectors and single band tests, repeat the steps above per involved band where single band test configurations and test models shall apply with no carrier activated in the other band.
The same procedure applies to TAB connectors declared to support 16QAM.
6.6.4.5 Test requirements
6.6.4.5.1 General
Conformance may be shown to either the measure and sum test requirement or the per TAB connector test requirement.
1) The spurious emission test requirements for an AAS BS when using the measure and sum alternative are that for each TAB connector TX cell group and each applicable basic limit as specified in this clause, the power summation of emissions at the TAB connectors of the TAB connector TX cell group shall not exceed a limit specified as the basic limit + 10log10(NTXU,countedpercell).
2) The spurious emission test requirements for an AAS BS when using the per TAB connector alternative are that for each TAB connector TX cell group and each applicable basic limit as specified in this clause, the emissions at each of the TAB connectors of the TAB connector TX cell group shall not exceed a limit specified as the basic limit + 10log10(NTXU,countedpercell) – 10log(n) where n is the number of TAB connectors in the TAB connector TX cell group.
The appropriate table for the basic limit is based on the same power level (PRated,c,sys) as used for the AAS BS rated power limits for BS classes in table 6.2.2.1-1 the same method of scaling the power level using NTXU,counted is used.
6.6.4.5.2 Basic Limits
6.6.4.5.2.1 UTRA FDD
The basic limit is specified in tables 6.6.4.5.2.1-1 to 6.6.4.5.2.1-11 for the appropriate PRated,c,sys, where:
– Δf is the separation between the carrier frequency and the nominal -3 dB point of the measuring filter closest to the carrier frequency.
– f_offset is the separation between the carrier frequency and the centre of the measurement filter;
– f_offsetmax is either 12.5 MHz or the offset to the UMTS Tx band edge as defined in clause 3.4.1, whichever is the greater.
– Δfmax is equal to f_offsetmax minus half of the bandwidth of the measuring filter.
Inside any Inter RF Bandwidth gap s with Wgap < 2×ΔfOBUE MHz for BS operating in multiple bands, emissions shall not exceed the cumulative sum of the test requirements specified at the Base Station RF Bandwidth edges on each side of the Inter RF Bandwidth gap. The basic limit for Base Station RF Bandwidth edge is specified in tables 6.6.4.5.2.1-1 to 6.6.4.5.2.1-11 below, where in this case:
– Δf is equal to 2.5 MHz plus the separation between the Base Station RF Bandwidth edge frequency and the nominal -3dB point of the measuring filter closest to the Base Station RF Bandwidth edge.
– f_offset is equal to 2.5 MHz plus the separation between the Base Station RF Bandwidth edge frequency and the centre of the measuring filter.
– f_offsetmax is either 12.5 MHz or the offset to the UMTS Tx band edge as defined in clause 5.2, whichever is the greater.
– Δfmax is equal to f_offsetmax minus half of the bandwidth of the measuring filter.
For a multi-band TAB connector, the operating band unwanted emission limits apply also in a supported operating band without any carrier transmitted, in the case where there are carrier(s) transmitted in another supported operating band. In this case, no cumulative limit is applied in the inter-band gap between a supported downlink operating band with carrier(s) transmitted and a supported downlink operating band without any carrier transmitted and
– In case the inter-band gap between a downlink band with carrier(s) transmitted and a downlink band without any carrier transmitted is less than 2×ΔfOBUE MHz, f_offsetmax shall be the offset to the frequency 10 MHz outside the outermost edges of the two downlink operating bands and the operating band unwanted emission limit of the band where there are carriers transmitted, as defined in the tables of the present clause, shall apply across both downlink bands.
– In other cases, the operating band unwanted emission limit of the band where there are carriers transmitted, as defined in the tables of the present clause for the largest frequency offset (Δfmax), shall apply from ΔfOBUE MHz below the lowest frequency, up to ΔfOBUE MHz above the highest frequency of the downlink operating band without any carrier transmitted.
Inside any sub-block gap for a TAB connector operating in non-contiguous spectrum, the measurement results shall not exceed the cumulative sum of the test requirements specified for the adjacent sub blocks on each side of the sub block gap. The basic limit for each sub block is specified in tables 6.6.4.5.2.1-1 to 6.6.4.5.2.1-11 below, where in this case:
– Δf is equal to 2.5 MHz plus the separation between the sub block edge frequency and the nominal -3 dB point of the measuring filter closest to the sub block edge.
– f_offset is equal to 2.5 MHz plus the separation between the sub block edge frequency and the centre of the measuring filter.
– f_offsetmax is equal to the sub block gap bandwidth minus half of the bandwidth of the measuring filter plus 2.5 MHz.
– Δfmax is equal to f_offsetmax minus half of the bandwidth of the measuring filter.

NOTE 1: For a TAB connector supporting non-contiguous spectrum operation the basic limit within sub-block gaps within any operating band is calculated as a cumulative sum of contributions from adjacent sub blocks on each side of the sub block gap, where the contribution from the far-end sub-block shall be scaled according to the measurement bandwidth of the near‑end sub-block. Exception is f ≥ 12.5 MHz from both adjacent sub blocks on each side of the sub-block gap, where the spurious emission basic limits in clauses 6.6.6.5.2.2 and 6.6.6.5.5.3 shall be met. NOTE 2: For a multi-band TAB connector with Inter RF Bandwidth gap < 2×ΔfOBUE MHz the minimum requirement within the Inter RF Bandwidth gaps is calculated as a cumulative sum of contributions from adjacent sub-blocks or RF Bandwidth on each side of the Inter RF Bandwidth gap, where the contribution from the far-end sub-block or Base Station RF Bandwidth shall be scaled according to the measurement bandwidth of the near-end sub‑block or Base Station RF Bandwidth. NOTE 4: This frequency range ensures that the range of values of f_offset is continuous. NOTE 5: As a general rule, the resolution bandwidth of the measuring equipment should be equal to the measurement bandwidth. However, to improve measurement accuracy, sensitivity and efficiency, the resolution bandwidth can be smaller than the measurement bandwidth. When the resolution bandwidth is smaller than the measurement bandwidth, the result should be integrated over the measurement bandwidth in order to obtain the equivalent noise bandwidth of the measurement bandwidth. |

NOTE 1: For a TAB connector supporting non-contiguous spectrum operation the basic limit within sub-block gaps within any operating band is calculated as a cumulative sum of contributions from adjacent sub blocks on each side of the sub block gap, where the contribution from the far-end sub-block shall be scaled according to the measurement bandwidth of the near-end sub-block. Exception is f ≥ 12.5 MHz from both adjacent sub blocks on each side of the sub-block gap, where the spurious emission basic limits in clauses 6.6.6.5.2.2 and 6.6.6.5.5.3 shall be met. NOTE 2: For a multi-band TAB connector with Inter RF Bandwidth gap < 2×ΔfOBUE MHz the minimum requirement within the Inter RF Bandwidth gaps is calculated as a cumulative sum of contributions from adjacent sub-blocks or Base Station RF Bandwidth on each side of the Inter RF Bandwidth gap, where the contribution from the far-end sub-block or Base Station RF Bandwidth shall be scaled according to the measurement bandwidth of the near-end sub-block or Base Station RF Bandwidth. NOTE 4: This frequency range ensures that the range of values of f_offset is continuous. NOTE 5: As a general rule, the resolution bandwidth of the measuring equipment should be equal to the measurement bandwidth. However, to improve measurement accuracy, sensitivity and efficiency, the resolution bandwidth can be smaller than the measurement bandwidth. When the resolution bandwidth is smaller than the measurement bandwidth, the result should be integrated over the measurement bandwidth in order to obtain the equivalent noise bandwidth of the measurement bandwidth. |

In certain regions the following requirement may apply for protection of DTT. For a TAB connector operating in Band XX, the level of emissions in the band 470-790 MHz, measured in an 8MHz filter bandwidth on centre frequencies Ffilter according to table 6.21F, shall not exceed the maximum emission level PEM,N declared by the manufacturer.

NOTE 1: The regional requirement is defined in terms of EIRP (effective isotropic radiated power), which is dependent on both the BS emissions at the antenna connector and the deployment (including antenna gain and feeder loss). The requirement defined above provides the characteristics of the basestation needed to verify compliance with the regional requirement. Compliance with the regional requirement can be determined using the method outlined in annex D of [1].
In certain regions, the following requirements may apply to a TAB connector operating in Band XXXII within 1452-1492 MHz. The level of unwanted emissions, measured on centre frequencies f_offset with filter bandwidth, according to table 6.6.4.5.2.1-13, shall neither exceed the maximum emission level PEM,B32,a , PEM,B32,b nor PEM,B32,c declared by the manufacturer.

NOTE 2: The regional requirement, included in [17], is defined in terms of EIRP per antenna, which is dependent on both the BS emissions at the antenna connector and the deployment (including antenna gain and feeder loss). The requirement defined above provides the characteristics of the base station needed to verify compliance with the regional requirement. The assessment of the EIRP level is described in annex H of TS 36.104 [11].
In certain regions, the following requirement may apply to TAB connector operating in Band XXXII within 1452-1492MHz for the protection of services in spectrum adjacent to the frequency range 1452-1492 MHz. The level of emissions, measured on centre frequencies Ffilter with filter bandwidth according to table 6.6.4.5.2.1-14, shall neither exceed the maximum emission level PEM,B32,d nor PEM,B32,e declared by the manufacturer.
