Aspects relate to cross-carrier scheduling in wireless communication. A scheduling entity generates scheduling information that schedules a plurality of data transmissions to or from a user equipment (UE) on a first carrier having a first numerology. The scheduling entity then transmits the scheduling information to the UE on a second carrier having a second numerology different than (e.g., less than) the first numerology. The scheduling information is transmitted using control resources allocated based on slot indexes of a plurality of slots configured for communicating the data transmissions on the first carrier.
