1. An apparatus for wireless communication, comprising:
a memory; and
at least one processor coupled to the memory, wherein the at least one processor is configured to:
establish a wireless connection via a set of component carriers (CCs) based on carrier aggregation (CA),
wherein the set of CCs includes at least a first CC that has a first sub-carrier spacing (SCS), and a second CC that has a second SCS that is different than the first SCS,
wherein a CA limit corresponds to a total number of control channel candidates across the set of CCs,
wherein a per-CC limit corresponds to a per-CC number of control channel candidates for each CC of the set of CCs;
determine a set of control channel candidates from the total number of control channel candidates, wherein to determine the set of control channel candidates, the at least one processor is configured to allocate control channel candidates across the set of CCs based on the CA limit and the per-CC limit,
wherein the set of control channel candidates includes blind decoding (BD) candidates or control channel element (CCE) candidates for channel estimation,
wherein a number of configured control channel candidates for at least one CC of the set of CCs exceeds the per-CC limit; and
communicate based on the set of control channel candidates.
