16. A method for wireless communication by a base station (BS), comprising:
identifying a carrier aggregation (CA) configuration in which at least a first component carrier (CC) of a plurality of CCs is aggregated with at least a second CC of the plurality of CCs;
receiving an indication of a first user equipment (UE) capability comprising a number of hybrid automatic repeat request (HARQ) processes supported by a UE;
determining a HARQ configuration comprising a pool of HARQ processes shared by at least the first CC and the second CC, wherein:
the first CC is associated with a first subcarrier spacing and the second CC is associated with a second subcarrier spacing different from the first subcarrier spacing;
the HARQ configuration allocates (i) a first number of HARQ processes, from the pool of HARQ processes, to the first CC based on the first subcarrier spacing and (ii) a second number of HARQ processes, from the pool of HARQ processes, to the second CC based on the second subcarrier spacing; and
a number of HARQ processes in the pool of HARQ processes is determined based on the first UE capability; and
signaling an indication of the HARQ configuration to the UE.
