Definition

The FeatureSetDownlinkId of a FeatureSetDownlink is the index position of the FeatureSetDownlink in the featureSetsDownlink list in the FeatureSets IE.

The FeatureSetDownlinkId=0 is not used by an actual FeatureSetDownlink but means that the UE does not support a carrier in this band of a band combination.
