Abstract: Aspects are provided allowing for selective monitoring of uplink cancellation indication (ULCI) occasions by UEs and allowing UEs to determine from ULCI whether canceled uplink transmission are carried on non-supplementary uplink (NUL) carriers or supplementary uplink (SUL) carriers. A UE may determine not to monitor a ULCI occasion if it does not have an uplink transmission which can be punctured by higher priority data. When the uplink transmission is dynamically scheduled, the UE may determine to monitor a ULCI occasion if the UE receives the uplink grant a certain number of symbols earlier than the ULCI occasion. The base station may configure blocks in downlink control information to indicate the UE should apply ULCI to SUL and/or NUL. The base station may configure the UE to perform different behaviors after receiving a ULCI depending on whether the portion of the uplink transmission to be canceled is on SUL or NUL.
