Method and apparatus for indicating deactivation of semi-persistent scheduling
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’.
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
the first field is entirely filled with ‘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).
