6.5A.1 Occupied bandwidth for CA

6.5A.1.0 General

The occupied bandwidth for UL CA is defined as a directional requirement. The requirement is verified in beam locked mode on beam peak direction. In case the intra-band CA configuration consists of a single UL CC, the occupied bandwidth requirement defined in subclause 6.5.1 applies.

6.5A.1.1 Occupied bandwidth for intra-band contiguous UL CA

For intra-band contiguous UL carrier aggregation, the occupied bandwidth is a measure of the bandwidth containing 99 % of the total integrated power of the transmitted spectrum. The occupied bandwidth for UL CA shall be less than the UL aggregated channel bandwidth defined in clause 5.3A.

6.5A.1.2 Occupied bandwidth for intra-band non-contiguous UL CA

For intra-band non-contiguous UL carrier aggregation, the occupied bandwidth requirement is met when the ratio of the transmitted power in all sub-blocks of the UL CA configuration to the total integrated power of the transmitted spectrum is greater than 99%.

6.5A.1.3 Occupied bandwidth for inter-band UL CA

For inter-band carrier aggregation with uplink assigned to two NR bands, and each UL band is configured with a single CC, the occupied bandwidth requirements is specified in clause 6.5.1 and is applicable for each CC with all CCs active with non-zero UL RB allocation.

6.5A.2 Out of band emissions

6.5A.2.1 Spectrum emission mask for CA

6.5A.2.1.0 General

For intra-band CA, the requirements specified in this clause shall apply if the UE has at least one of UL or DL configured for CA or if the UE is configured for single CC operation with different channel bandwidths in UL and DL carriers. In case the CA configuration consists of a single UL CC, spectrum emission mask defined in subclause 6.5.2.1 applies. Spectral emission mask requirements do not apply at any frequency where IBE requirements of clause 6.4A.2.3 apply.

The requirement is verified in beam locked mode with the test metric of TRP (Link=TX beam peak direction).

6.5A.2.1.1 Spectrum emission mask for intra-band contiguous UL CA

For intra-band contiguous UL carrier aggregation, the spectrum emission mask of the UE applies to frequencies (Δf_OOB) starting from the ± edge of the UL aggregated channel bandwidth (Table 5.3A.5-1). For any bandwidth class defined in Table 5.3A.5-1, the UE emission shall not exceed the levels specified in Table 6.5A.2.1-1.

Table 6.5A.2.1.1-1: General NR spectrum emission mask for intra-band contiguous CA in FR2-1 and FR2-2

Δf_OOB (MHz)	Any carrier aggregation bandwidth class	Measurement bandwidth
± 0-0.1*BW_{Channel_CA}	-5	1 MHz
± 0.1BW_{Channel_CA} -2BW_{Channel_CA}	-13	1 MHz
NOTE 1: (void)

6.5A.2.1.2 Spectrum emission mask for intra-band non-contiguous UL CA

For intra-band non-contiguous UL carrier aggregation, the spectrum emission mask requirement is defined as a composite spectrum emissions mask. Composite spectrum emission mask applies to frequencies up to ± Δf_OOB starting from the edge of each UL sub-block. Composite spectrum emission mask is defined as follows:

a) Composite spectrum emission mask is a combination of individual spectrum emissions masks defined for each sub-block. If for some frequency, spectrum emission masks from multiple sub-blocks overlap, the spectrum emission mask allowing the highest power spectral density applies for that frequency

b) In case a sub-block comprises of multiple component carriers, the spectrum emissions mask is defined in subclause 6.5A.2.1.1 or in case of a single component carrier, the sub-block spectrum emission mask is defined in subclause 6.5.2.1

c) If for some frequency the spectrum emission mask of one sub-block overlaps another sub-block, the emission mask does not apply for that frequency.

d) If carrier leakage or I/Q image lands inside the spectrum occupied by the configured UL and DL CCs, exception to the general spectrum emission mask limit applies. For carrier leakage the requirements specified in section 6.4A.2.2 shall apply. For I/Q image the requirements specified in section 6.4A.2.3 shall apply.

6.5A.2.1.3 Spectrum emission mask for inter-band UL CA

For inter-band carrier aggregation with uplink assigned to two NR bands, and each UL band is configured with a single CC, the spectrum emission mask is specified in Table 6.5.2.1-1 for each CC separately while both CCs are active with non-zero UL RB allocation. If for some frequency spectrum emission masks of CCs overlap, then spectrum emission mask allowing higher power spectral density applies for that frequency. If for some frequency a CC spectrum emission mask overlaps with the channel bandwidth of another CC, then the emission mask does not apply for that frequency.

6.5A.2.3 Adjacent channel leakage ratio for CA

6.5A.2.3.1 Adjacent channel leakage ratio for CA intra-band contiguous UL CA

In case the CA configuration consists of a single UL CC, the adjacent channel leakage ratio defined in subclause 6.5.2.3 applies. For intra-band contiguous UL carrier aggregation, the carrier aggregation NR adjacent channel leakage power ratio (CA NR_ACLR) is the ratio of the filtered mean power centred on the UL aggregated channel bandwidth to the filtered mean power centred on an adjacent UL aggregated channel bandwidth at spacing equal to the UL aggregated channel bandwidth. The assigned UL aggregated channel bandwidth power and adjacent UL aggregated channel bandwidth power are measured with rectangular filters with measurement bandwidths specified in Table 6.5A.2.3.1-1. If the measured adjacent channel power is greater than -35 dBm then the CA NR_ACLR shall be higher than the value specified in Table 6.5A.2.3.1-1.

Table 6.5A.2.3.1-1: General requirements for contiguous UL CA NR_ACLR

	CA bandwidth class / CA NR_ACLR / Measurement bandwidth
	Any CA bandwidth class
CA NR_ACLRfor band n257, n258, n261	17 dB

CA NR_ACLRfor band n263	15 dB
NR channel measurement bandwidth¹	BW_{Channel_CA} – 2*BW_GB
Adjacent channel centre frequency offset (in MHz)	+ BW_{Channel_CA} / – BW_{Channel_CA}
NOTE 1: BW_GBis defined in clause 5.3A.2.

6.5A.2.3.2 Adjacent channel leakage ratio for CA intra-band non-contiguous UL CA

For intra-band non-contiguous carrier aggregation, adjacent channel leakage power ratio (CA NR_ACLR) is the ratio of the sum of the filtered mean powers centred on each sub-block bandwidth to the filtered mean power centred on an adjacent sub-block frequency at nominal spacing equal to the sub-block bandwidth. The power in the configured UL CCs and power in the sub-block bandwidth adjacent to each sub-block of configured UL CCs are measured with rectangular filters with measurement bandwidths specified in Table 6.5A.2.3.1-2. In case a sub-block consists of a single component carrier, the measurement bandwidths and adjacent frequency offset from subclause 6.5.2.3 shall be used. If the measured adjacent sub-block power is greater than -35 dBm then the CA NR_ACLR shall be higher than the value specified in Table 6.5A.2.3.1-2.

No requirement applies in the gap between neighbouring sub-blocks if the frequency span between the lowest edge of the upper sub-block and the highest edge of the lower sub-block is smaller than the bandwidth of either sub-block.

	CA bandwidth class / CA NR_ACLR / Measurement bandwidth
	Any CA bandwidth class

NOTE 1: BWChannel_block is defined in clause 5.3A.2. NOTE 2: ‘Adjacent sub-block centre frequency offset’ is defined for each sub-block in the UL CA configuration

6.5A.2.3.3 Adjacent channel leakage ratio for CA inter-band UL CA

For inter-band carrier aggregation with uplink assigned to two NR bands, and each UL band is configured with a single CC, the NR Adjacent Channel Leakage power Ratio (NR_ACLR) is applicable for each CC while both CCs are active with non-zero UL RB allocation and the requirement is specified in clause 6.5.2.3.

6.5A.3 Spurious emissions for CA

6.5A.3.0 General spurious emissions for CA

6.5A.3.0.0 General

This clause specifies the spurious emission requirements for carrier aggregation. The requirement is verified in beam locked mode with the test metric of TRP (Link=TX beam peak direction).

For intra-band CA, in case the CA configuration consists of a single UL CC, spurious emissions requirements defined in subclause 6.5.3 apply. Spurious emissions requirements do not apply at any frequency where IBE requirements of clause 6.4A.2.3 apply.

NOTE: For measurement conditions at the edge of each frequency range, the lowest frequency of the measurement position in each frequency range should be set at the lowest boundary of the frequency range plus MBW/2. The highest frequency of the measurement position in each frequency range should be set at the highest boundary of the frequency range minus MBW/2. MBW denotes the measurement bandwidth defined for the protected band.

6.5A.3.0.1 Spurious emissions for intra-band contiguous UL CA

For intra-band contiguous UL carrier aggregation, the spurious emission limits apply for the frequency ranges that are more than F_OOB (MHz) from the edge of the UL aggregated channel bandwidth, where F_OOB is defined as the twice the UL aggregated channel bandwidth. For frequencies Δf_OOB greater than F_OOB, the spurious emission requirements in Table 6.5.3-2 are applicable.

6.5A.3.0.2 Spurious emissions for intra-band non-contiguous UL CA

For intra-band non-contiguous UL carrier aggregation, the spurious emission requirement is defined as a composite spurious emission requirement which is a combination of individual spurious emission requirements defined for each UL sub-block. The limits in Table 6.5.3-2 apply for the frequency ranges that are more than F_OOB (MHz) from the edge of each UL sub-block but excludes frequency ranges that coincide with another UL sub-block. No spurious emission limit applies in the gap between neighbouring UL sub-blocks if the frequency span between the lowest edge of the upper sub-block and the highest edge of the lower sub-block is smaller than F_{OOB_L}+ F_{OOB_H}.

6.5A.3.0.3 Spurious emissions for inter-band UL CA

For inter-band carrier aggregation with uplink assigned to two NR bands, and each UL band is configured with a single CC, the spurious emission requirements are specified in clause 6.5.3 and are applicable for each CC with all CCs active with non-zero UL RB allocation.

6.5A.3.1 Spurious emission band UE co-existence for UL CA

This clause specifies the requirements for the specified contiguous or non-contiguous UL carrier aggregation configurations for coexistence with protected bands.

For intra-band contiguous, non-contiguous carrier aggregation and inter-band carrier aggregation, the requirements in Table 6.5A.3-1 apply.
