1. A method for wireless communications performed by a user equipment (UE), comprising:
receiving a low priority (LP) grant, via downlink control information (DCI), for scheduling an LP uplink transmission in a slot, the LP uplink transmission overlapping a set of high priority (HP) uplink transmissions in the slot, each HP uplink transmission being scheduled via a respective second DCI;
determining an uplink shared channel preparation time as a function of a subcarrier spacing (SCS) configuration and a UE processing time capability based on the LP uplink transmission overlapping the set of HP uplink transmissions, the SCS configuration corresponding to a smallest SCS configuration selected from a first SCS configuration associated with an HP grant corresponding to an HP uplink transmission of the set of HP uplink transmissions, a second SCS configuration associated with the HP uplink transmission of the set of HP uplink transmissions, a third SCS configuration associated with the LP grant, and a fourth SCS configuration associated with the LP uplink transmission;
determining a time period until a respective expected transmission time for each HP uplink transmission of the set of HP uplink transmissions scheduled based on a corresponding HP grant, the time period being a function of the uplink shared channel preparation time and a time duration corresponding to a reported UE capability; and
canceling the LP uplink transmission before a symbol of the LP uplink transmission overlaps an earliest HP uplink transmission of the set of HP uplink transmissions, the earliest HP uplink transmission being based on the time period.
