TIMELINE FOR INTRA-USER EQUIPMENT (UE) CHANNEL MULTIPLEXING AND CANCELLATION

Abstract:

A method for wireless communications performed by a user equipment (UE) includes receiving a low priority (LP) grant for scheduling an LP uplink transmission in a slot. The LP uplink transmission may overlap a set of high priority (HP) uplink transmissions in the slot. The method also includes 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 method further includes determining a time period until an expected transmission time for each respective 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. The method also includes 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.
