Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a first carrier having a first subcarrier spacing (SCS), a scheduling indication via a physical downlink control channel (PDCCH) scheduling a downlink transmission on a second carrier having a second SCS. The UE may process the downlink transmission on the second carrier based at least in part on a delay between the PDCCH and the scheduled downlink transmission and a timing threshold having a basic term and an adjustment term. For example, the basic term may be based at least in part on a minimum delay between the PDCCH and the scheduled downlink transmission, and the adjustment term may be based at least in part on a processing time due to a difference between the first SCS and the second SCS. Numerous other aspects are provided.
