Abstract

A method and apparatus for performing semi-persistent scheduling (SPS) deactivation in a wireless mobile communication system are disclosed. A base station (BS) transmits a downlink control channel to a user equipment (UE), and deactivates the SPS when a binary field indicating resource allocation information contained in the downlink control channel is entirely filled with ‘1’.

Claims

1. A method for deactivating Semi-Persistent Scheduling (SPS) transmission in a wireless mobile communication system, the method comprising:

performing, by a User Equipment (UE), a SPS transmission at an interval of a subframe period configured by a radio resource control (RRC) signal;

receiving, by the UE, a Physical Downlink Control Channel (PDCCH) signal with a Radio Network Temporary Identifier (RNTI), wherein the PDCCH signal includes a first field related to a resource allocation; and

performing a procedure for deactivating the SPS transmission if the PDCCH signal satisfies conditions for SPS deactivation,

wherein the conditions for SPS deactivation include;

the RNTI is a SPS Cell RNTI (SPS C-RNTI); and

the first field is entirely filled with ‘

1’

.

2. The method of claim 1,

wherein the PDCCH signal further includes a second field related to Transmission Power Control (TPC) and a third field related to a DeModulation Reference Signal (DM RS),

wherein the conditions for SPS deactivation further include:

the second field is entirely filled with ‘

0’

, and

the third field is entirely filled with ‘

1’

.

3. The method of claim 1, wherein the PDCCH signal carries a Downlink Control Information (DCI) format ‘

0’

.

4. The method of claim 1, wherein the first field indicates a Resource Indication Value (RIV).

5. The method of claim 1, further comprising:

continuing, by the UE, the SPS transmission if the PDCCH signal does not satisfy the conditions for SPS deactivation.

6. A method for deactivating Semi-Persistent Scheduling (SPS) reception in a wireless mobile communication system, the method comprising:

performing, by a Base Station (BS), a SPS reception at an interval of a subframe period configured by a radio resource control (RRC) signal;

transmitting, by the BS, a Physical Downlink Control Channel (PDCCH) signal with a Radio Network Temporary Identifier (RNTI), wherein the PDCCH signal includes a first field related to a resource allocation; and

performing a procedure for deactivating the SPS reception if the PDCCH signal satisfies conditions for SPS deactivation,

wherein the conditions for SPS deactivation include;

the RNTI is a SPS Cell RNTI (SPS C-RNTI); and

the first field is entirely filled with ‘

1’

.

7. The method of claim 6,

wherein the PDCCH signal further includes a second field related to Transmission Power Control (TPC) and a third field related to a DeModulation Reference Signal (DM RS),

wherein the conditions for SPS deactivation further include:

the second field is entirely filled with ‘

0’

, and

the third field is entirely filled with ‘

1’

.

8. The method of claim 6, wherein the PDCCH signal carries a Downlink Control Information (DCI) format ‘

0’

.

9. The method of claim 6, wherein the first field indicates a Resource Indication Value (RIV).

10. The method of claim 6, further comprising:

continuing, by the BS, the SPS reception if the PDCCH signal does not satisfy the conditions for SPS deactivation.

11. A User Equipment (UE) used for in a wireless mobile communication system, the UE configured to:

perform a Semi-Persistent Scheduling (SPS) transmission at an interval of a subframe period configured by a radio resource control (RRC) signal;

receive a Physical Downlink Control Channel (PDCCH) signal with a Radio Network Temporary Identifier (RNTI), wherein the PDCCH signal includes a first field related to a resource allocation; and

performing a procedure for deactivating the SPS transmission if the PDCCH signal satisfies conditions for SPS deactivation,

wherein the conditions for SPS deactivation include;

the RNTI is a SPS Cell RNTI (SPS C-RNTI); and

the first field is entirely filled with ‘

1’

.

12. The UE of claim 11, wherein the PDCCH signal further includes a second field related to Transmission Power Control (TPC) and a third field related to a DeModulation Reference Signal (DM RS),

wherein the conditions for SPS deactivation further include:

the second field is entirely filled with ‘

0’

, and

the third field is entirely filled with ‘

1’

.

13. The UE of claim 11, wherein the PDCCH signal carries a Downlink Control Information (DCI) format ‘

0’

.

14. The UE of claim 11, wherein the first field indicates a Resource Indication Value (RIV).

15. The UE of claim 11, wherein the UE is further configured to continue the SPS transmission if the PDCCH signal does not satisfy the conditions for SPS deactivation.

16. A Base Station (BS) used for in wireless mobile communication system, the BS configured to:

perform a SPS reception at an interval of a subframe period configured by a radio resource control (RRC) signal;

transmit a Physical Downlink Control Channel (PDCCH) signal with a Radio Network Temporary Identifier (RNTI), wherein the PDCCH signal includes a first field related to a resource allocation; and

perform a procedure for deactivating the SPS reception if the PDCCH signal satisfies conditions for SPS deactivation,

wherein the conditions for SPS deactivation include;

the RNTI is a SPS Cell RNTI (SPS C-RNTI); and

1’

.

17. The BS of claim 16, wherein the PDCCH signal further includes a second field related to Transmission Power Control (TPC) and a third field related to a DeModulation Reference Signal (DM RS),

wherein the conditions for SPS deactivation further include:

the second field is entirely filled with ‘

0’

, and

the third field is entirely filled with ‘

1’

.

18. The BS of claim 16, wherein the PDCCH signal carries a Downlink Control Information (DCI) format ‘

0’

.

19. The BS of claim 16, wherein the first field indicates a Resource Indication Value (RIV).

20. The BS of claim 16, wherein the BS is further configured to continue the SPS reception if the PDCCH signal does not satisfy the conditions for SPS deactivation.
