System and method for performing transmission cancellation indication monitoring

1. A method of providing, by a network to a user equipment (UE) device, a transmission grant, the method comprising:

initiating a process to provide the transmission grant for a transmission within a cancellation time window at a time falling within the cancellation window;

verifying that there is no cancellation indication indicating a cancellation that is within the cancellation time window; and

providing, based on the verifying that there is no cancellation indication indicating the cancellation that is within the cancellation time window, the transmission grant to the UE device.

2. The method of claim 1 , wherein the transmission grant is a first transmission grant, and the cancellation time window is a first cancellation time window, the method further comprising:

verifying that there is a cancellation indication indicating a cancellation that is within a second cancellation time window; and

withholding, based on the verifying that there is the cancellation indication indicating the cancellation that is within the second cancellation time window, a second transmission grant to the UE device.

3. The method of claim 1 , further comprising:

determining a grant window in which the transmission grant for the transmission falling within the cancellation time window can be provided to the UE device;

verifying that the transmission grant falls within the grant window; and

providing, based on the verifying that the transmission grant falls within the grant window, the transmission grant to the UE device.

4. The method of claim 3 , wherein the network does not provide any transmission grant outside of the grant window.

5. The method of claim 1 , wherein:

the cancellation time window includes a starting point at a time T 1 following an ending point of a monitoring occasion, the time T 1 being based on a time needed by the UE device to process a cancellation of the transmission grant.

6. The method of claim 5 , wherein the grant window includes an ending point at a time T 2 before a starting point of the monitoring occasion, the time T 2 being based on a time needed by the UE device for processing the transmission grant.

7. The method of claim 6 , further comprising receiving, by the network, an indication of the time T 2 from the UE device.

8. The method of claim 1 , wherein:

an ending point of the cancellation time window is based on a period “P” of a monitoring occasion; and

a length of the cancellation time window is equal to the period “P” of the monitoring occasion.

9. The method of claim 1 , wherein the transmission grant is a first transmission grant, method further comprising:

inferring no receipt of a second transmission grant that is a PDCCH carrying UL grant including an ending symbol no earlier than a first symbol of a physical downlink control channel (PDCCH) carrying downlink control information (DCI) with the cancellation indication, wherein the inferring is based on whether a corresponding transmission is in resource colliding with ones indicated by the DCI with the cancellation indication.

10. The method of claim 1 , wherein the transmission grant is a first transmission grant and the verifying that there is no cancellation indication comprises verifying that there is no cancellation indication for the first transmission grant, the method further comprising:

verifying that there is a cancellation indication indicating a cancellation for a second transmission grant that is within the cancellation time window; and

withholding, based on the verifying that there is the cancellation indication indicating the cancellation that is within the cancellation time window, the second transmission grant to the UE device.

11. A method for reducing processing burden within a user equipment (UE) device, the method comprising:

inferring, by a cancellation indication monitoring logic section of the UE device, that a transmission grant will not be received whose starting point is the same or later than a starting point of a cancellation indication, wherein the inferring is based on whether a transmission is cancelled by the cancellation indication; and

based on the inferring that the transmission grant will not be received whose starting point is the same or later than the starting point of the cancellation indication, temporarily stopping monitoring for potential one or more physical downlink control channel (PDCCH) transmissions.

12. The method of claim 11 , further comprising:

inferring, by the cancellation indication monitoring logic section of the UE device, that cancelled symbols indicated by the cancellation indication will not be scheduled to transmit when the starting point of the transmission grant is not the same or later than the starting point of the cancellation indication, wherein the inferring is based on whether the transmission is cancelled by the cancellation indication.

13. The method of claim 11 , wherein the transmission grant is a first transmission grant, method further comprising:

inferring, by the cancellation indication monitoring logic section of the UE device, no receipt of a second transmission grant that is a PDCCH carrying UL grant including an ending symbol no earlier than a first symbol of a PDCCH carrying downlink control information (DCI) with the cancellation indication, wherein the inferring is based on whether a corresponding transmission is in resource colliding with ones indicated by the DCI with the cancellation indication.

14. The method of claim 11 , wherein the transmission grant is a PDCCH carrying UL grant, the method further comprising:

when an ending symbol of the PDCCH carrying UL grant is earlier than a first symbol of a PDCCH carrying downlink control information (DCI) with the cancellation indication, applying the DCI with the cancellation indication to a PDCCH carrying UL grant scheduling transmission.

15. The method of claim 11 , further comprising:

determining, by the cancellation indication monitoring logic section of the UE device, that there is no transmission that is within a cancellation window; and

based on the determining that there is no transmission that is within the cancellation window, skipping a monitoring occasion.

16. The method of claim 15 , wherein skipping includes not expending any processing cycles of the UE device doing any monitoring for the cancellation indication during the monitoring occasion.

17. The method of claim 11 , further comprising:

ensuring, by a network, that an ending point of the transmission grant is at least a time T 2 before a starting point of a monitoring occasion, the time T 2 being based on a time needed by the UE device for processing the transmission grant;

determining, by the cancellation indication monitoring logic section of the UE device, that the transmission grant will not be received whose ending point is later than the time T 2 before the starting point of the monitoring occasion; and

based on the determining that the transmission grant will not be received whose ending point is later than the time T 2 before the starting point of the monitoring occasion, skipping the monitoring occasion.

18. A system, comprising:

a user equipment (UE) device; and

a remote server configured to provide a transmission grant for a transmission within a cancellation time window, wherein the remote server is further configured to:

verify that there is no cancellation indication indicating a cancellation that is within the cancellation time window; and

provide, based on a verification that there is no cancellation indication indicating the cancellation that is within the cancellation time window, the transmission grant to the UE device.

19. The system of claim 18 , wherein the remote server is further configured to:

verify that there is a cancellation indication indicating a cancellation that is within the cancellation time window; and

withhold, based on a verification that there is the cancellation indication indicating the cancellation that is within the cancellation time window, the transmission grant to the UE device.

20. The system of claim 18 , wherein the remote server is further configured to:

determine a grant window in which the transmission grant for the transmission falling within the cancellation time window can be provided to the UE device, wherein the remote server does not provide any transmission grant outside of the grant window;

verify that the transmission grant falls within the grant window; and

provide, based on a verification that the transmission grant falls within the grant window, the transmission grant to the UE device.

21. The system of claim 20 , wherein:

the cancellation window includes a starting point at a time T 1 following an ending point of a monitoring occasion, the time T 1 being based on a time needed by the UE device to process a cancellation of the transmission grant; and

the grant window includes an ending point at a time T 2 before a starting point of the monitoring occasion, the time T 2 being based on a time needed by the UE device for processing the transmission grant.

22. The system of claim 18 , wherein the cancellation time window is a first cancellation time window, and wherein the remote server is further configured to:

verify that there is a cancellation indication indicating a cancellation that is within a second cancellation time window; and

withhold, based on a verification that there is the cancellation indication indicating the cancellation that is within the second cancellation time window, the transmission grant to the UE device.
