A user equipment (UE) may receive signaling that schedules a set of uplink transmissions that at least partially overlap in a time domain, the set of uplink transmissions including at least one dynamic grant based uplink transmission and at least one configured grant based uplink transmission, each uplink transmission is associated with a corresponding transmission group of a set of available transmission groups for simultaneous serving cell transmissions. The UE may receive a control message indicating a prioritization configuration for the set of uplink transmissions that at least partially overlap in the time domain. The UE may cancel at least an overlapping portion of one uplink transmission in the set of uplink transmissions based at least in part on the at least partial overlap in the time domain, the corresponding transmission group, and the prioritization configuration.
