 –  FeatureSetCombination  p. 1172

The IE FeatureSetCombination is a two-dimensional matrix of FeatureSet entries.
Each FeatureSetsPerBand contains a list of feature sets applicable to the carrier(s) of one band entry of the associated band combination. Across the associated bands, the UE shall support the combination of FeatureSets at the same position in the FeatureSetsPerBand. All FeatureSetsPerBand in one FeatureSetCombination must have the same number of entries.
The number of FeatureSetsPerBand in the FeatureSetCombination must be equal to the number of band entries in an associated band combination. The first FeatureSetPerBand applies to the first band entry of the band combination, and so on.
Each FeatureSet contains either a pair of NR or E-UTRA feature set IDs for UL and DL.
In case of NR, the actual feature sets for UL and DL are defined in the FeatureSets IE and referred to from here by their ID, i.e., their position in the featureSetsUplink / featureSetsDownlink list in the FeatureSet IE.
In case of E-UTRA, the feature sets referred to from this list are defined in TS 36.331 and conveyed as part of the UE-EUTRA-Capability container.
The FeatureSetUplink and FeatureSetDownlink referred to from the FeatureSet comprise, among other information, a set of FeatureSetUplinkPerCC-Ids and FeatureSetDownlinkPerCC-Ids. The number of these per-CC IDs determines the number of carriers that the UE is able to aggregate contiguously in frequency domain in the corresponding band. The number of carriers supported by the UE is also restricted by the bandwidth class indicated in the associated BandCombination, if present.
In feature set combinations the UE shall exclude entries with same or lower capabilities, since the network may anyway assume that the UE supports those.
