Abstract

A method, system and apparatus for uplink transmission cancellation are disclosed. According to one aspect, a method includes receiving a cancellation indication of uplink resources to be cancelled, determining protected uplink resources to be protected from cancellation, and cancelling transmissions on uplink resources indicated to be cancelled other than uplink resources determined to be protected from cancellation.

First claim

What is claimed is:

1. A wireless device (WD), configured to communicate with a network node, the WD comprising processing circuitry configured to:
receive a cancellation indication of uplink resources to be cancelled;
determine protected uplink resources to be protected from cancellation, the determined protected uplink resources including uplink resources for uplink control channel transmissions, the determined protected uplink resources being indicated by the cancellation indication; and
cancel transmissions on uplink resources indicated to be cancelled other than the determined protected uplink resources, the uplink resources for uplink control channel transmissions being excluded from being canceled even if the cancellation indication indicates that the resources to be cancelled are overlapping with the uplink resources for uplink control channel transmissions.

2. The WD of claim 1 , wherein the determined protected uplink resources are semi-statically configured.

3. The WD of claim 1 , wherein the determined protected uplink resources include uplink resources for transmissions determined to be high priority transmissions.

4. The WD of claim 1 , wherein the determined protected uplink resources include uplink resources for random access channel transmissions.

5. The WD of claim 1 , wherein the determined protected uplink resources do not include uplink resources for uplink shared channel transmissions.

6. The WD of claim 1 , wherein the determined protected uplink resources do not include uplink resources for sounding reference signal transmissions.

7. A method in a wireless device (WD), configured to communicate with a network node, the method comprising:
receiving a cancellation indication of uplink resources to be cancelled;
determining protected uplink resources to be protected from cancellation, the determined protected uplink resources including uplink resources for uplink control channel transmissions, the determined protected uplink resources being indicated by the cancellation indication; and
cancelling transmissions on uplink resources indicated to be cancelled other than the determined protected uplink resources, the uplink resources for uplink control channel transmissions being excluded from being canceled even if the cancellation indication indicates that the resources to be cancelled are overlapping with the uplink resources for uplink control channel transmissions.

8. The method of claim 7 , wherein the determined protected uplink resources are semi-statically configured.

9. The method of claim 7 , wherein the determined protected uplink resources include uplink resources for transmissions determined to be high priority transmissions.

10. The method of claim 7 , wherein the determined protected uplink resources include uplink resources for random access channel transmissions.

11. The method of claim 7 , wherein the determined protected uplink resources do not include uplink resources for uplink shared channel transmissions.

12. The method of claim 7 , wherein the determined protected uplink resources do not include uplink resources for sounding reference signal transmissions.

13. A network node configured to communicate with a wireless device (WD), the network node comprising:
processing circuitry configured to designate uplink resources of the WD as protected uplink resources, the protected uplink resources including uplink resources for uplink control channel transmissions, the protected uplink resources being indicated by a cancellation indication; and
a radio interface configured to transmit to the WD a protected resources indication indicating the protected uplink resources, the uplink resources for uplink control channel transmissions being excluded from being canceled even if the cancellation indication indicates that the resources to be cancelled are overlapping with the uplink resources for uplink control channel transmissions.

14. The network node of claim 13 , wherein the processing circuitry is further configured to designate uplink resources to be cancelled and the radio interface is further configured to transmit to the WD a cancellation indication of the uplink resources to be cancelled.

15. The network node of claim 14 , wherein the cancellation indication is transmitted in downlink control information (DCI).

16. The network node of claim 13 , wherein the protected resources indication is transmitted in downlink control information (DCI).

17. The network node of claim 13 , wherein the protected resources indication is transmitted in a group common message to be received by WDs in a group.

18. The network node of claim 13 , wherein the protected resources indication indicates time domain resources, but not frequency domain resources.

19. A method in a network node configured to communicate with a wireless device (WD), the method comprising:
designating uplink resources of the WD as protected uplink resources, the protected uplink resources including uplink resources for uplink control channel transmissions, the protected uplink resources being indicated by a cancellation indication; and
transmitting to the WD a protected resources indication indicating the protected uplink resources, the uplink resources for uplink control channel transmissions being excluded from being canceled even if the cancellation indication indicates that the resources to be cancelled are overlapping with the uplink resources for uplink control channel transmissions.

20. The method of claim 19 , further comprising designating uplink resources to be cancelled and the radio interface is further configured to transmit to the WD a cancellation indication of the uplink resources to be cancelled.

21. The method of claim 20 , wherein the cancellation indication is transmitted in downlink control information (DCI).

22. The method of claim 19 , wherein the protected resources indication is transmitted in downlink control information (DCI).

23. The method of claim 19 , wherein the protected resources indication is transmitted in a group common message to be received by WDs in a group.

24. The method of claim 19 , wherein the protected resources indication indicates time domain resources, but not frequency domain resources.
