Abstract

A user equipment (UE) is configured with a carrier aggregation (CA) functionality and 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. The UE determines a plurality of bands that are supported by the UE for use in the CA functionality, generates an individual band information element (IE) including band information for the bands, determines at least one representative CA combination having an order, the order indicating a total number of component carriers (CCs), the at least one representative CA combination forming a basis to extrapolate a plurality of CA combinations having the order based on the band information, generates a representative CA combination IE including the at least one representative CA combination and transmits the individual band IE and the representative CA combination IE to the base station.

Dependent claims

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.

4 more elements

A user equipment (UE), comprising:

a transceiver configured with a carrier aggregation (CA) functionality to connect to a network via a first base station that serves as a primary serving cell (PCell) providing a primary component carrier (PCC) and at least one second base station that serves as a secondary serving cell (SCell) providing a secondary component carrier (SCC);
and
a processor configured to determine a plurality of bands that are supported by the UE for use in the CA functionality, generate an individual band information element (IE) including band information for the bands, determine at least one representative CA combination having an order, the order indicating a total number of component carriers (CCs), the at least one representative CA combination 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 and generate a representative CA combination IE including the at least one representative CA combination.
