1. A method for wireless communication, comprising:

  • identifying a band combination, wherein the identified band combination comprises;

    a plurality of bands available for carrier aggregation at a user equipment (UE), wherein a set of possible carrier bandwidth combinations for the plurality of bands comprises combinations of available carrier bandwidths for each band of the plurality of bands, anda plurality of carrier bandwidth combination sets, wherein each carrier bandwidth combination set is associated with a respective subset of the set of possible carrier bandwidth combinations;

    identifying a carrier bandwidth combination set that is supported by the UE from the plurality of carrier bandwidth combination sets;

    sending signaling indicative of the identified carrier bandwidth combination set, the signaling comprising a bitmap having a plurality of bits, each bit of the bitmap being associated with a different one of the plurality of carrier bandwidth combination sets; and

    communicating with a base station on the plurality of bands using a carrier bandwidth combination selected from the identified carrier bandwidth combination set indicated by the UE.
