Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for encoding uplink data for transmission based on control information included in a first uplink grant corresponding to a first set of uplink resources, receiving a second uplink grant associated with a second set of uplink resources, wherein the second uplink grant is associated with the encoded uplink data for transmission, determining a starting time (e.g., a first delay or a second delay) for the second set of uplink resources based at least in part on a timing of the encoding with respect to the second uplink grant, and transmitting uplink data during the second set of uplink resources based on the determined starting time.
