6.6.3.1 Definition and applicability
Adjacent Channel Leakage power Ratio (ACLR) is the ratio of the filtered mean power centred on the assigned channel frequency to the filtered mean power centred on an adjacent channel frequency.
NOTE: Conformance to the AAS ACLR requirement can be demonstrated by meeting at least one of the following criteria as determined by the manufacturer:
1) The ratio of the sum of the filtered mean power measured on each TAB connector in the TAB connector TX min cell group at the assigned channel frequency to the sum of the filtered mean power measured on each TAB connector in the TAB connector TX min cell group at the adjacent channel frequency shall be greater than or equal to the AAS ACLR limit. This applies for each TAB connector TX min cell group.
Or
2) The ratio of the filtered mean power at the TAB connector centred on the assigned channel frequency to the filtered mean power at each TAB connector centred on the adjacent channel frequency shall be greater than or equal to the AAS limit for every TAB connector in the TAB connector TX min cell group, for each TAB connector TX min cell group.

6.6.3.5.3.4 Cumulative ACLR requirement in non-contiguous spectrum
The following test requirement applies for sub-block or Inter RF Bandwidth gap sizes listed in table 6.6.3.5.3.4-1 for UTRA FDD, UTRA TDD or E-UTRA operation or table 6.6.3.5.3.4-1A for NR operation:
– Inside a sub-block gap within an operating band for a BS operating in non-contiguous spectrum.
– Inside an Inter RF Bandwidth gap for a BS operating in multiple bands, where multiple bands are mapped on the same antenna connector.
The Cumulative Adjacent Channel Leakage power Ratio (CACLR) in a sub-block gap or the Inter RF Bandwidth gap is the ratio of:
a) the sum of the filtered mean power centred on the assigned channel frequencies for the two carriers adjacent to each side of the sub-block gap or the Inter RF Bandwidth gap; and
b) the filtered mean power centred on a frequency channel adjacent to one of the respective sub-block edges or Base Station RF Bandwidth edges.
The requirement applies to adjacent channels of E-UTRA or UTRA or NR carriers allocated adjacent to each side of the sub‑block gap or the Inter RF Bandwidth gap. In case of mixed UTRA and E-UTRA (but not NR) carriers on either side of the gap, table 6.6.3.5.3.4-1 is applicable. In case of mixed NR and E-UTRA or UTRA or NR only carriers on either side of the gap, table 6.6.3.5.3.4-1A is applicable. The assumed filter for the adjacent channel frequency is defined in tables 6.6.3.5.3.4-1 and 6.6.3.5.3.4-1A and the filters on the assigned channels are defined in table 6.6.3.5.3.4-2.
NOTE: If the RAT on the assigned channel frequencies is different, the filters used are also different.
The CACLR for E-UTRA and UTRA carriers located on either side of the sub-block gap or the Inter RF Bandwidth gap shall be higher than the value specified in table 6.6.3.5.3.4-1.
