1. An apparatus for wireless communication at a network entity, comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to cause the network entity to:
provide a first downlink control information (DCI) for a first user equipment (UE) based on a particular aggregation level of a plurality of aggregation levels associated with a control channel,
wherein the plurality of aggregation levels includes:
a first aggregation level that is a highest aggregation level of the plurality of aggregation levels, and
a second aggregation level that is lower than the first aggregation level,
wherein a first candidate sample at the highest aggregation level spans a region of a physical downlink control channel (PDCCH) payload region,
wherein a second candidate sample at the second aggregation level spans a first portion of the region,
wherein a third candidate sample at the second aggregation level spans a second portion of the region, and
wherein the particular aggregation level is the second aggregation level; and
provide a second DCI for a second UE.
