1. A method, comprising:
at a user equipment (UE) configured with a carrier aggregation (CA) functionality, the UE connected to a network via a base station that serves as a primary serving cell (PCell) providing a primary component carrier (PCC) to the UE:
determining a plurality of bands that are supported by the UE for use in the CA functionality;
generating an individual band information element (IE) including band information for the bands;
determining at least one representative CA combination having an order, the order indicating a total number of component carriers (CCs), wherein each of the at least one representative CA combination is configured to be used as a basis for the base station to extrapolate a plurality of CA combinations supported by the UE having the order based on the band information;
generating a representative CA combination IE including the at least one representative CA combination; and
transmitting the individual band IE and the representative CA combination IE to the base station.
