Jitter indication by cross-slot scheduling downlink control information
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information with a value in an information element that is associated with identifying an offset between a first downlink slot in which the downlink control information is received and a second downlink slot in which shared channel data is scheduled. The UE may communicate data after a duration associated with the value in the information element and without monitoring for a physical downlink control channel communication during the duration. Numerous other aspects are described.
