Definition

The IE FeatureSets is used to provide pools of downlink and uplink features sets. A FeatureSetCombination refers to the IDs of the feature set(s) that the UE supports in that FeatureSetCombination . The BandCombination entries in the BandCombinationList then indicate the ID of the FeatureSetCombination that the UE supports for that band combination.
