37.145-23GPPActive Antenna System (AAS) Base Station (BS) conformance testingPart 2: radiated conformance testingRelease 17TS

6.7.4.1 Definition and applicability

This requirement is applicable for AAS BS in single RAT UTRA operation only.

The spectrum emission mask minimum requirements are quoted as TRP unless otherwise stated.

6.7.4.2 Minimum requirement

For AAS BS in single RAT UTRA operation the minimum requirement is defined in TS 37.105 [6], clause 9.7.4.3.

This requirement does not apply to single RAT E-UTRA operation or MSR operation.

6.7.4.3 Test purpose

This test measures the emissions of the AAS BS, close to the assigned channel bandwidth of the wanted signal, while the AAS BS is in operation.

6.7.4.4 Method of test

6.7.4.4.1 Initial conditions

6.7.4.4.1.1 General test conditions

Test environment:

– normal; see annex G.2.

RF channels to be tested for single carrier:

– B, M and T; see clause 4.12.1.

Base Station RF Bandwidth positions to be tested for multi-carrier:

– BRFBW, MRFBW and TRFBW in single-band operation; see clause 4.12.1; BRFBW_T’RFBW and B’RFBW_TRFBW in multi-band operation, see clause 4.12.1.

6.7.4.4.1.2 UTRA FDD

For an AAS BS declared to be capable of single carrier operation only, set to transmit a signal according to TM1, in clause 4.12.2.

For a multi-carrier capable AAS BS, set to transmit according to TM1 on all carriers configured using the applicable test configuration.

6.7.4.4.2 Procedure

The following procedure for measuring TRP is based on the directional power measurements as described in in Annex F. An alternative method to measure TRP is to use a characterized and calibrated reverberation chamber if so follow steps 1, 3, 4, 5, 7 and 10.

1) Place the AAS BS at the positioner.

2) Align the manufacturer declared coordinate system orientation (see table 4.10-1, D9.2) of the AAS BS with the test system.

3) The measurement devices characteristics shall be:

– a 30 kHz measurement bandwidth.

– Measurements with an offset from the carrier centre frequency between 2,515 MHz and 4.0 MHz shall use 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 voltage or true power averaging.

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.

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.

4) For single carrier operation, set the AAS BS to transmit according to the applicable test configuration in clause 5 using the corresponding test model(s) in clause 4.12.2 at manufacturers declared rated carrier TRP (Prated,c,TRP).

For an AAS BS declared to be capable of multi-carrier and/or CA operation use the applicable test signal configuration and corresponding power setting specified in clause 4.11.

5) For UTRA FDD multi-band RIB or RIB 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.

6) Orient the positioner (and BS) in order that the direction to be tested aligns with the test antenna such that measurements to determine TRP can be performed (see annex F).

7) Sweep the centre frequency of the measurement filter in contiguous steps and measure emission power within the specified frequency ranges with the specified measurement bandwidth.

8) Repeat step 6-7 for all directions in the appropriated TRP measurement grid needed for TRPEstimate (see Annex F).

9) Calculate TRPEstimate using the measurements made in Step 7.

In addition, for multi-band RIB, the following steps shall apply:

10) For multi-band RIB 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.

6.7.4.5 Test Requirement

6.7.4.5.1 UTRA FDD

The measurement result shall not exceed the test requirements specified in Tables 6.7.4.5.1-1 to 6.7.4.5.1-11 for the appropriate Prated,c,TRP, 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 of TS 25.141 [10], whichever is the greater.

– Δfmax is equal to f_offsetmax minus half of the bandwidth of the measuring filter.

Inside any Inter RF Bandwidth gaps with Wgap < 2×ΔfOBUE for a multi-band RIB, emissions shall not exceed the cumulative sum of the minimum requirements specified at the Base Station RF Bandwidth edges on each side of the Inter RF Bandwidth gap. The minimum requirements for Base Station RF Bandwidth edge is specified in the tables 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, whichever is the greater.

– Δfmax is equal to f_offsetmax minus half of the bandwidth of the measuring filter.

For a multi-band RIB, the operating band unwanted emission minimum requirements 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 , f_offsetmax shall be the offset to the frequency ΔfOBUE 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 below the lowest frequency, up to ΔfOBUE above the highest frequency of the downlink operating band without any carrier transmitted.

Inside any sub-block gap for a RIB operating in non-contiguous spectrum, emissions shall not exceed the cumulative sum of the minimum requirements specified for the adjacent sub blocks on each side of the sub-block gap. The minimum requirement for each sub block is specified in the tables 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 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 test requirement may apply for protection of DTT. For a RIB operating in Band XX, the level of emissions in the band 470-790 MHz, measured in an 8 MHz filter bandwidth on centre frequencies Ffilter according to Table 6.7.4.5.1-12, shall not exceed the maximum emission level TRP in Table 6.7.4.5.1-12.

NOTE: PEIRP_10 MHz (dBm) is defined by the expression PEIRP_10 MHz = P10 MHz + Gant + 6dB for UTRA and PEIRP_10 MHz = P10 MHz + Gant + 9dB for E-UTRA, where Gant is [17] dBi

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 method outlined in annex B1, TS 37.105 [6] indicates how the limit in Table 6.7.4.5.1-12 demonstrates compliance to the regional requirement

In certain regions, the following test requirements may apply to a RIB 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 6.7.4.5.1-13, shall not exceed the maximum TRP limits indicated in the table.

NOTE 2: The regional requirement, included in CEPT ECC Decision (13)03 [xx], 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 method outlined in annex B, TS 37.105 [6] indicates how the limit in Table 6.7.4.5.1-13 demonstrates compliance to the regional requirement.

In certain regions, the following test requirement may apply to RIB operating in Band XXXII within 1452-1492 MHz 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 6.7.4.5.1-14, shall not exceed the maximum emission TRP limits in the table. This requirement applies in the frequency range 1429-1518 MHz even though part of the range falls in the spurious domain.
