Abstract

A method of improving SPS reconfiguration for a user equipment in a wireless communication system includes receiving an RRC connection reconfiguration message and reconfiguring SPS resources in accordance with an SPS resources configuration IE when the SPS resources configuration IE is included in the RRC connection reconfiguration message and is set enable.

Claims

1. A method of improving semi-persistent scheduling, abbreviated to SPS, resources reconfiguration for a user equipment in a wireless communication system, the method comprising:

receiving a radio resource control, abbreviated to RRC, connection reconfiguration message; and

reconfiguring SPS resources in accordance with an SPS resources configuration information element, abbreviated to IE, when the SPS resources configuration IE is included in the RRC connection reconfiguration message and SPS resources configuration is set enable.

2. The method of claim 1, wherein the step of reconfiguring the SPS resources in accordance with the SPS resources configuration IE when the SPS resources configuration IE is included in the RRC connection reconfiguration message and the SPS resources configuration is set enable comprises reconfiguring downlink SPS resources in accordance with a downlink SPS resources configuration IE when the downlink SPS resources configuration IE is included in the RRC connection reconfiguration message and downlink SPS resources configuration is set enable.

3. The method of claim 2 further comprising deactivating any activated downlink SPS resource when the downlink SPS resources are reconfigured.

4. The method of claim 2 further comprising activating the downlink SPS resource when receiving a PDCCH signaling for activating downlink SPS resources.

5. The method of claim 1, wherein the step of reconfiguring the SPS resources in accordance with the SPS resources configuration IE when the SPS resources configuration IE is included in the RRC connection reconfiguration message and the SPS resources configuration is set enable comprises reconfiguring uplink SPS resources in accordance with an uplink SPS resources configuration IE when the uplink SPS resources configuration IE is included in the RRC connection reconfiguration message and uplink SPS resources configuration is set enable.

6. The method of claim 5 further comprising deactivating any activated uplink SPS resource when the uplink SPS resource are reconfigured.

7. The method of claim 5 further comprising activating the uplink SPS resource when receiving a PDCCH signaling for activating uplink SPS resources.

8. The method of claim 1 further comprising deactivating any activated SPS resource when an SPS cell radio network temporary identifier (SPS C-RNTI) is changed before the step of reconfiguring the SPS resources in accordance with the SPS resources configuration IE.

9. The method of claim 8, wherein the step of deactivating any activated SPS resource when the SPS C-RNTI is changed comprises deactivating any activated downlink SPS resource when the SPS C-RNTI is changed.

10. The method of claim 8, wherein the step of deactivating any activated SPS resource when the SPS C-RNTI is changed comprises deactivating any activated uplink SPS resource when the SPS C-RNTI is changed.

11. A communication device of a wireless communication system for improving semi-persistent scheduling, abbreviated to SPS, resources reconfiguration, the communication device comprising:

a computer readable recording medium for storing program code corresponding to a process; and

a processor coupled to the computer readable recording medium, for processing the program code to execute the process, wherein the process comprises;

receiving a radio resource control, abbreviated to RRC, connection reconfiguration message; and

reconfiguring SPS resources in accordance with an SPS resources configuration information element, abbreviated to IE, when the SPS resources configuration IE is included in the RRC connection reconfiguration message and SPS resources configuration is set enable.

12. The communication device of claim 11, wherein the step of reconfiguring the SPS resources in accordance with the SPS resources configuration IE when the SPS resources configuration IE is included in the RRC connection reconfiguration message and the SPS resources configuration is set enable comprises reconfiguring downlink SPS resources in accordance with a downlink SPS resources configuration IE when the downlink SPS resources configuration IE is included in the RRC connection reconfiguration message and downlink SPS resources configuration is set enable.

13. The communication device of claim 12, wherein the process further comprises deactivating any activated downlink SPS resource when the downlink SPS resource are reconfigured.

14. The communication device of claim 12, wherein the process further comprises activating the downlink SPS resource when receiving a PDCCH signaling for activating downlink SPS resources.

15. The communication device of claim 11, wherein the step of reconfiguring the SPS resources in accordance with the SPS resources configuration IE when the SPS resources configuration IE is included in the RRC connection reconfiguration message and the SPS resources configuration is set enable comprises reconfiguring uplink SPS resources in accordance with an uplink SPS resources configuration IE when the uplink SPS resources configuration IE is included in the RRC connection reconfiguration message and uplink SPS resources configuration is set enable.

16. The communication device of claim 15, wherein the process further comprises deactivating any activated uplink SPS resource when the uplink SPS resource are reconfigured.

17. The communication device of claim 15, wherein the process further comprises activating the uplink SPS resource when receiving a PDCCH signaling for activating uplink SPS resources.

18. The communication device of claim 11, wherein the process further comprises deactivating any activated SPS resource when an SPS cell radio network temporary identifier (SPS C-RNTI) is changed before the step of reconfiguring the SPS resources in accordance with the SPS resources configuration IE.

19. The communication device of claim 18, wherein the step of deactivating any activated SPS resource when the SPS C-RNTI is changed comprises deactivating any activated downlink SPS resource when the SPS C-RNTI is changed.
