Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

6.6.4.1 General

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

6.6.4.2 Minimum requirement for MSR operation

There is no spectrum emission mask requirement for an MSR AAS BS.

6.6.4.3 Minimum requirement for single RAT UTRA operation

6.6.4.3.1 General

The spectrum emission mask requirements for a UTRA single RAT AAS BS are that for each applicable basic limit as specified in 3GPP TS 25.104 [2] or TS 25.105 [7], and for each TAB connector TX min cell group the power sum of emissions at the TAB connectors of the TAB connector TX min cell group shall not exceed an AAS BS limit specified as the basic limits + 10log₁₀(N_{TXU,countedpercell}).

NOTE: Conformance to the AAS BS spectrum emission mask requirement can be demonstrated by meeting at least one of the following criteria as determined by the manufacturer:

1) The sum of the emissions power measured on each TAB connector in the TAB connector TX min cell group shall be less than or equal to the AAS limit as defined in this subclause for the respective frequency span.

2) The spectrum emission mask power at each TAB connector shall be less than or equal to the AAS BS limit as defined in this subclause for the respective frequency span, scaled by -10log₁₀(n), where n is the number of TAB connectors in the TAB connector TX min cell group.

6.6.4.3.2 Basic limits for single RAT UTRA FDD operation

The basic limit is specified in tables 6.6.4.3.2-1 to 6.6.4.3.2-10 for the appropriate P_Rated,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_offset_max is either 12.5 MHz or the offset to the UMTS Tx band edge as defined in clause 5.2, whichever is the greater.

– Δf_max is equal to f_offset_max minus half of the bandwidth of the measuring filter.

Inside any Inter RF Bandwidth gaps with Wgap < 2×Δf_OBUE for a multi-band TAB connector, emissions shall not exceed the cumulative sum of the basic limits 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 6.6.4.3.2-1 to 6.6.4.3.2-10 below, where in this case:

– Δf is equal to 2.5MHz 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 2.5MHz plus the separation between the Base Station RF Bandwidth edge frequency and the centre of the measuring filter.

– f_offset_max is either 12.5 MHz or the offset to the UMTS Tx band edge as defined in clause 5.2, whichever is the greater.

– Δf_max is equal to f_offset_max minus half of the bandwidth of the measuring filter.

For a multi-band TAB connector, the operating band unwanted emission basic 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×Δf_OBUE, f_offset_max shall be the offset to the frequency Δf_OBUE 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 subclause, 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 subclause for the largest frequency offset (Δf_max), shall apply from Δf_OBUE below the lowest frequency, up to Δf_OBUE 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, emissions shall not exceed the cumulative sum of the basic limits 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 6.6.4.3.2-1 to 6.6.4.3.2-10 below, where in this case:

– Δf is equal to 2.5MHz 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 2.5MHz plus the separation between the sub block edge frequency and the centre of the measuring filter.

– f_offset_max is equal to the sub-block gap bandwidth minus half of the bandwidth of the measuring filter plus 2.5MHz.

– Δf_max is equal to f_offset_max minus half of the bandwidth of the measuring filter.

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 F_filter according to table 6.6.4.3.2-8, shall not exceed the maximum emission basic limit P_EM,N declared by the manufacturer.

F_filter = 8*N + 306 (MHz); 21 ≤ N ≤ 60	8 MHz	P_EM,N

NOTE: 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 basic limit defined above provides the characteristics of the AAS base station needed to verify compliance with the regional requirement. Compliance with the regional requirement for protection of DTT can be determined using the method outlined in annex D of 3GPP TS 25.104 [2].

In certain regions, the following basic limits 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 6.6.4.3.2-9, shall neither exceed the maximum emission basic limit P_{EM,B32,a ,}P_EM,B32,bnor P_EM,B32,c declared by the manufacturer.

NOTE: f_offset_{max, B32} denotes the frequency difference between the lower channel carrier frequency and 1454.5 MHz, and the frequency difference between the upper channel carrier frequency and 1489.5 MHz for the set channel position.

NOTE: The regional requirement, included in CEPT ECC Decision (13)03 [25], 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 basic limit 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 3GPP TS 36.104 [4].

In certain regions, the following basic limit 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 F_filter with filter bandwidth according to table 6.6.4.3.2-10, shall neither exceed the maximum emission basic limit P_EM,B32,dnor P_EM,B32,e declared by the manufacturer. This requirement applies in the frequency range 1429-1518MHz even though part of the range falls in the spurious domain.

The assessment of the EIRP level is described in annex H of 3GPP TS 36.104 [4].

Notes for the tables in this subclause:

NOTE 3: This frequency range ensures that the range of values of f_offset is continuous.

NOTE 4: 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.

6.6.4.3.3 Basic limits for single RAT UTRA TDD 1,28Mcps operation

The basic limit is specified in tables 6.6.4.3.3-1 to 6.6.4.3.3-3 for the appropriate P_Rated,c,sy, where:

The mask defined in table 6.6.4.3.3-1 to 6.6.4.3.3-3 may be mandatory in certain regions. In other regions this mask may not be applied.

For regions where this clause applies, the basic limit is for a TAB connector transmitting on a single RF carrier configured in accordance with the manufacturer’s specification. Emissions shall use the basic limits specified in table 6.6.4.3.3-1 to 6.6.4.3.3-3 for the appropriate P_rated,c,cell, in the frequency range from Δf = 0.8 MHz to Δf _max from the carrier frequency, where:

– Δf is the separation between the carrier frequency and the nominal -3dB point of the measuring filter closest to the carrier frequency.

– f_offset is the separation between the carrier frequency and the centre frequency of the measuring filter.- f_offset_max is either 4 MHz or the offset to the UTRA TDD Tx band edge as defined in subclause 4.6, whichever is the greater.

– Δf _maxis equal to f_offset_maxminus half of the bandwidth of the measurement filter. Inside any Inter RF bandwidth gaps with W_gap < 8 MHz for multi-band TAB connector, emissions shall not exceed the cumulative sum of the basic limits specified at the Base Station RF bandwidth edges on each side of Inter RF bandwidth gap. The basic limit for Base Station RF bandwidth edge is specified in tables 6.6.4.3.3-1 to 6.6.4.3.3-3 below, where in this case.

– Δf equal to 0.8MHz 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 0.8MHz plus the separation between the Base Station RF bandwidth edge frequency and the centre frequency of the measuring filter.

– f_offset_max is either 4 MHz or the offset to the UTRA TDD Tx band edge as defined in subclause 4.6, whichever is the greater.

– Δf max is equal to f_offsetmax minus half of the bandwidth of the measurement filter.

For a multi-carrier TAB connector, the definitions above apply to the lower edge of the carrier transmitted at the lowest carrier frequency and the upper edge of the carrier transmitted at the highest carrier frequency within a specified frequency.
