Methods and apparatus to selectively monitor uplink preemptive indication for supplementary uplink and non-supplementary uplink carriers

An apparatus for wireless communication, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive scheduling information for an uplink transmission from a base station, the uplink transmission being dynamically scheduled using downlink control information (DCI);
• and
• monitor at least one uplink cancellation indication (ULCI) occasion from the base station based on the scheduling information and based on a separation in time between the scheduling information and the ULCI occasion, wherein the apparatus monitors the at least one ULCI occasion when the DCI is received a threshold number of symbols before the at least one ULCI occasion, and the threshold number of symbols is 1.

A method of wireless communication at a base station comprising:

• scheduling a user equipment (UE) for an uplink transmission, the uplink transmission for the UE being dynamically scheduled using downlink control information (DCI);
• transmitting an uplink cancellation indication (ULCI) at an ULCI occasion based on whether the UE will monitor the ULCI occasion for the uplink transmission including a separation in time between the scheduling and the ULCI occasion, the ULCI cancelling at least a portion of the uplink transmission, if the UE will monitor the ULCI occasion;
• and
• transmitting the ULCI in a next ULCI occasion if the ULCI occasion is less than a threshold number of symbols after the DCI, wherein the threshold number of symbols is 1.

An apparatus for wireless communication, comprising:

• means for scheduling a user equipment (UE) for an uplink transmission, the uplink transmission for the UE being dynamically scheduled using downlink control information (DCI);
• means for transmitting an uplink cancellation indication (ULCI) at an ULCI occasion based on whether the UE will monitor the ULCI occasion for the uplink transmission including a separation in time between the scheduling and the ULCI occasion, the ULCI cancelling at least a portion of the uplink transmission, if the UE will monitor the ULCI occasion;
• and
• means for transmitting the ULCI in a next ULCI occasion if the ULCI occasion is less than a threshold number of symbols after the DCI, wherein the threshold number of symbols is 1.

• transmit the ULCI in a next ULCI occasion if the ULCI occasion is less than a threshold number of symbols after the DCI, wherein the threshold number of symbols is 1.

A non-transitory computer-readable medium storing computer executable code, the code when executed by a processor causes the processor to:

• schedule a user equipment (UE) for an uplink transmission, the uplink transmission for the UE being dynamically scheduled using downlink control information (DCI);
• transmit an uplink cancellation indication (ULCI) at an ULCI occasion based on whether the UE will monitor the ULCI occasion for the uplink transmission including a separation in time between the scheduling and the ULCI occasion, the ULCI cancelling at least a portion of the uplink transmission, if the UE will monitor the ULCI occasion;
• and
• transmit the ULCI in a next ULCI occasion if the ULCI occasion is less than a threshold number of symbols after the DCI, wherein the threshold number of symbols is 1.
