1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving configuration information for a plurality of carriers, wherein a set of first carriers of the plurality of carriers are single transmit receive point (single-TRP) carriers and a set of second carriers of the plurality of carriers are multi-TRP carriers;
determining, for the plurality of carriers, a distribution that satisfies a per-span capability of the UE, wherein the distribution is of at least one of a plurality of non-overlapped control channel elements (CCEs) or a plurality of blind decodes, wherein the distribution is based at least in part on which carriers, of the plurality of carriers, are single-TRP carriers or multi-TRP carriers, and wherein the distribution is further based at least in part on a rule indicating that, for a given span associated with a given subcarrier spacing, a given physical downlink control channel configuration, and an alignment of search space sets with a given span configuration, across the set of first carriers or the set of second carriers, the UE is not to receive a number of non-overlapped CCEs or perform a number of blind decodes that exceeds a determined number of blind decodes or non-overlapped CCEs; and
receiving communications on the plurality of carriers in accordance with the distribution.
