Abstract

A method is provided for acknowledging a semi-persistent scheduling (SPS) uplink resource release. The method comprising receiving an uplink SPS resource release signal over a physical downlink control channel (PDCCH), and sending an acknowledgement (ACK) to confirm the reception of the uplink SPS resource release signal. Also provided is a user equipment (UE) comprising a processor configured to receive an uplink SPS resource release signal over a PDCCH, and transmit an ACK to confirm the reception of the uplink SPS resource release signal.

Claims

1. A method for acknowledging a semi-persistent scheduling (SPS) uplink resource release, comprising:

receiving an uplink SPS resource release signal over a physical downlink control channel (PDCCH); and

sending an acknowledgement (ACK) to confirm the reception of the uplink SPS resource release signal.

2. The method of claim 1, wherein the ACK is transmitted using a resource associated with the resource over which the SPS resource release signal for the uplink is transmitted over the PDCCH.

3. The method of claim 1, wherein the SPS resource release signal is indicated using a downlink control information (DCI) format 1A over the PDCCH.

4. The method of claim 3, wherein the DCI format 1A comprises one reserved bit that is set to indicate an uplink SPS resource release or a downlink SPS resource release.

5. The method of claim 3, wherein the ACK is transmitted using a resource associated with the resource over which the DCI format 1A of the PDCCH is transmitted.

6. The method of claim 1, wherein the SPS resource release signal is indicated using a downlink control information (DCI) format 0 over the PDCCH.

7. The method of claim 6, wherein the ACK is transmitted using a resource linked to the resource over which the DCI format 0 is transmitted over the PDCCH.

8. The method of claim 7, wherein the ACK is transmitted using a resource associated with a control channel element (CCE) index of the DCI format 0 over the PDCCH.

9. The method of claim 1, wherein the ACK is transmitted using the resource signaled by a high layer signaling.

10. The method of claim 9, wherein the ACK resource is signaled using a radio resource control (RRC) signaling.

11. A method for acknowledging a semi-persistent scheduling (SPS) uplink resource release, comprising:

sending an uplink SPS resource release signal over a physical downlink control channel (PDCCH); and

receiving an acknowledgement (ACK) to confirm the reception of the uplink SPS resource release signal.

12. The method of claim 11, wherein the ACK is transmitted using a resource associated with the resource over which the SPS resource release signal for the uplink is transmitted over the PDCCH.

13. The method of claim 11, wherein the SPS resource release signal is indicated using a downlink control information (DCI) format 1A over the PDCCH.

14. The method of claim 13, wherein the DCI format 1A comprises one reserved bit that is set to one to indicate an uplink SPS resource release or a downlink SPS resource release.

15. The method of claim 13, wherein the ACK is received using a resource associated with the resource over which the DCI format 1A of the PDCCH is transmitted.

16. The method of claim 11, wherein the SPS resource release signal is indicated using a downlink control information (DCI) format 0 over the PDCCH.

17. The method of claim 11, wherein the ACK is received using a resource which is signaled by the high layer signaling.

18. The method of claim 17, wherein the high layer signaling further includes the RRC signaling.

19. The method of claim 11, wherein an access device transmits the SPS resource release signal for the uplink to a user equipment (UE), and wherein the UE transmits the ACK to the access device.

20. A user equipment (UE) comprising:

a processor configured to receive an uplink semi-persistent scheduling (SPS) resource release signal over a physical downlink control channel (PDCCH); and

transmit an acknowledgement (ACK) to confirm the reception of the uplink SPS resource release signal.

21. The UE of claim 20, wherein the ACK is transmitted using a resource associated with the resource over which the SPS resource release signal for the uplink is transmitted over the PDCCH.

22. The UE of claim 20, wherein the SPS resource release signal is indicated using a downlink control information (DCI) format 1A over the PDCCH.

23. The UE of claim 22, wherein the DCI format 1A comprises one reserved bit that is set to one to indicate an uplink SPS resource release or a downlink SPS resource release.

24. The UE of claim 22, wherein the ACK is transmitted using a resource associated with the resource over which the DCI format 1A of the PDCCH is transmitted.

25. The UE of claim 20, wherein the SPS resource release signal is indicated using a downlink control information (DCI) format 0 over the PDCCH.

26. The UE of claim 25, wherein the ACK is transmitted using a resource linked to the resource over which the DCI format 0 is transmitted over the PDCCH.

27. The UE of claim 26, wherein the ACK is transmitted using a resource associated with a control channel element (CCE) index of the DCI format 0 over the PDCCH.

28. The UE of claim 20, wherein the ACK is transmitted using the resource signaled by a high layer signaling.

29. The UE of claim 28, wherein the ACK is transmitted using the resource signaled by a radio resource control (RRC) signaling.

30. An access device comprising:

a processor configured to transmit an uplink semi-persistent scheduling (SPS) resource release signal over a physical downlink control channel (PDCCH); and

receive an acknowledgement (ACK) to confirm the reception of the uplink SPS resource release signal.

31. The access device of claim 30, wherein the ACK is transmitted using a resource associated with the resource over which the SPS resource release signal for the uplink is transmitted over the PDCCH.

32. The access device of claim 30, wherein the SPS resource release signal is indicated using a downlink control information (DCI) format 1A over the PDCCH.

33. The access device of claim 32, wherein the DCI format 1A comprises one reserved bit that is set to one to indicate an uplink SPS resource release or a downlink SPS resource release.

34. The access device of claim 32, wherein the ACK is received using a resource associated with the resource over which the DCI format 1A of the PDCCH is transmitted.

35. The access device of claim 30, wherein the SPS resource release signal is indicated using a downlink control information (DCI) format 0 over the PDCCH.

36. The access device of claim 30, wherein the ACK is received using a resource which is signaled by the high layer signaling.
