In which:

- (NTXU,counted) is the number of TAB connector that transmit signals.

- 10log(NTXU,counted) is used to calculate the total output power at all TAB connectors of base station Type 1-H.

2.2.2. Transmitter ON/OFF power

This requirement applies only to base stations that operate in TDD duplex mode.

2.2.2.1. Definition

Transmitter OFF power is the average power measured over 70/N µs filtered with a square filter of bandwidth equal to the transmission configuration bandwidth of the base station centered on the assigned channel frequency during the transmitter OFF period.

N = sub-carrier spacing (kHz)/15.

For multi-band connectors, the requirement is only applicable during the transmitter OFF period in all operating bands.

For base stations supporting contiguous spectrum CA, the transmitter OFF power is the average power over 70/N µs filtered with a square filter of a bandwidth equal to the aggregated base station channel bandwidth centered on (Fedge, low + Fedge,high)/2 during the transmitter OFF period.

N = (Minimum sub-carrier spacing (kHz) in the aggregated base station channel bandwidth)/2.

2.2.2.2. Limits

- Base station Type 1-C: Transmitter OFF power at the antenna connector ≤ -85 dBm/MHz

- Base station Type 1-H: Transmitter OFF power at the TAB connector ≤ -85 dBm/MHz

2.2.3. Transmitter transition period

2.2.3.1. Definition

Transmitter transition period means the period during which the transmitter is changing from ON to OFF and vice versa.

2.2.3.2. Limits

Base stations Type 1-C, 1-H: Transmitter transient period ≤ 10 µs.

2.2.4. Unwanted emissions

Unwanted emissions include out-of-band emissions and spurious emissions.

- Out-of-band emissions are unwanted emission immediately outside the channel bandwidth resulting from the modulation process and nonlinearity in the transmitter but excluding spurious emissions.

- Spurious emissions are emissions that are caused by unwanted transmitter effects such as harmonic emissions, parasitic emissions, intermodulation products and frequency conversion products, excluding out-of-band emissions.

The limit of the BS transmitter's out-of-band emissions is determined in accordance with the operating band unwanted emissions and the adjacent channel leakage power ratio (ACLR).

ΔfOBUE means the maximum offset between the unwanted emissions in the operating band and the operating band edge. The unwanted emissions are defined as all emissions in each downlink band and the frequency ranges ΔfOBUE above and ΔfOBUE below each band. Unwanted emissions are emissions outside the frequency ranges mentioned above. ΔfOBUE is determined as shown in Table 8.

Note: For Base station Type 1-H, the unwanted emissions are applied to the TAB connector TX min cell group in all supported configurations.

2.2.5. Adjacent channel leakage power ratio ACLR

2.2.5.1. Definition

Adjacent channel leakage power ratio (ACLR) means the ratio of the RRC mean power on the assigned channel to the RRC mean power on the adjacent channel.

The requirements apply outside the base station RF bandwidth of single-band, multi-band base stations and with any transmission mode declared by the manufacturer.

For base stations transmitting in non-contiguous spectrum, ACLR and CACLR shall apply within sub-block gaps. For a multi-band connector, ACLR and CACLR shall apply within the Inter RF Bandwidth gap. These requirements are determined during the transmitter ON period.

2.2.6. Operating band unwanted emissions

2.2.6.1. Definition

Unless otherwise stated, the operating band unwanted emissions in FR1 are defined from ΔfOBUE below the lowest frequency to ΔfOBUE above the highest frequency of each operating band. The value of ΔfOBUE is determined as shown in Table 8.

This requirement applies to all types of transmitter and transmission modes declared by the manufacturer. For base stations operating in the non-contiguous spectrum, the unwanted emission requirements shall apply in the sub-blocks. For a base station operating in multi bands, these requirements apply within the Inter RF Bandwidth gap.

  • ∆f is the gap between the channel edge frequency and the nominal -3dB point of the measuring filter closest to the carrier frequency.
  • f_offsetis the distance between the channel edge frequency and the center frequency of the measuring filter.
  • f_offsetmax is the offset of the frequency fOBUE outside the operating downlink band.
  • ∆fmax is equal to f_offsetmaxless half of the bandwidth of the measuring filter

For multi-band connectors within any Inter RF Bandwidth gap with Wgap< 2* fOBUE, the requirement shall apply to the cumulative total of limits related to base station bandwidth edges at each side of the Inter RF Bandwidth gap. The provisions for RF bandwidth edges are specified in this section, in which:

- ∆f is the gap between the base station RF bandwidth edge frequency and the nominal -3 dB point of the measuring filter closest to the base station RF bandwidth edge.

- f_offsetis the frequency offset between the base station RF bandwidth edge and the center frequency of the measuring filter.

- f_offsetmax is equal to the Inter RF Bandwidth gapless half of the bandwidth of the measurement filter.

- ∆fmax is equal to f_offsetmaxless half of the bandwidth of the measuring filter.

For a multi-band connector, the operating band unwanted emission limits shall apply to all bands supported by the base station. In this case, the cumulative limit of spurious emissions applies to the Inter RF Bandwidth gap between the supported downlink operating band with transmitted carriers and a supported downlink operating band without transmitting any carrier and:

- Where the Inter RF Bandwidth gap of the downlink operating band is supported with a transmitted carrier and a supported downlink operating band without transmitting any carrier and is less than 2*ΔfOBUE, f_offsetmax shall be the offset of the frequency ΔfOBUE outside the edges of the two supported downlink operating bands, and the operating band unwanted emission limit shall apply to both downlink operating bands.

- In other cases, the operating band unwanted emissions shall be applied from ΔfOBUE below the lowest frequency to ΔfOBUE above the highest frequency of the supported operating band without transmitting any carrier.

For a multi-carrier connector or a single-band connector operating in the non-contiguous carrier aggregation, in-band unwanted emissions apply to the lower edge of the transmitted carrier of the highest carrier frequency in a specified operating band.

Additionally, within any sub-block gap of a single-band connector operating in non-contiguous spectrum, limits are cumulatively applied to adjacent sub-blocks on each side of the sub-block gap, specified in this section, in which

-∆f is the gap between the sub-block frequency edge and the nominal -3 dB point of the measuring filter closest to the sub-block edge.

- f_offset is the offset between the sub-block edge and the center frequency of the filter.

- f_offsetmax is equal to the sub-block gap width less half of the bandwidth of the measuring filter.

- ∆fmax is equal to f_offsetmaxlesshalf of the bandwidth of the measuring filter.

For base stations Type 1-C, the requirements apply to each antenna connector.

For base stations Type 1-H, the TAB connector TX min cell group does not exceed the X plus base limits, where X is 10log10 (NTXU,countedpercell).

The total power of spurious emissions measured at each TAB connector TX min cell group shall be less than or equal to the specified limit.

2.2.6.2. Limits

In particular, for some operating bands, the upper limit is higher than 12.75 GHz in order to comply with recommendation ITU-R SM.329.

For base stations Type 1-C, the requirements apply to each antenna connector.

For base stations Type 1-H, the requirement that apply to the TAB connector TX min cell group shall not exceed the + X basic limits, where, X=10.log10(NTXU,countedpercell). The total power of spurious emissions measured at each TAB connector TX min cell group shall be less than or equal to the specified limit.

Unless otherwise stated, all requirements in this section are measured as mean power.

2.2.8. Transmitter intermodulation

2.2.8.1. Definition

Transmitter intermodulation is a measure of the transmitter's ability to eliminate the formation of signals in its nonlinear elements due to the presence of wanted and interfering signals at the transmitter antenna. This requirement applies during the transmitter ON period and the transmitter transient period.
