Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first downlink control information (DCI) at a first time, and may receive a second DCI at a second, later time. Each DCI may contain scheduling information for scheduling a number of transmissions at the UE. A transmission associated with the first DCI on a first cell may be scheduled to start before or during a transmission associated with the second DCI on a second cell. The UE may then determine priorities associated with the first and second cells. In cases where the priority of the second cell is greater than the priority of the first cell, the UE may transmit the second scheduled transmission before it transmits the first scheduled transmission. As a result, the UE may prioritize transmitting the second scheduled transmission before the first scheduled transmission.
