Method of improving semi-persistent scheduling resources reconfiguration in a wireless communication system and related communication device
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.
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 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 the downlink SPS resources configuration IE is set to enable;
wherein any activated downlink SPS resource is deactivated when the downlink SPS resources are reconfigured; and the downlink SPS resource is activated when receiving a PDCCH signaling for activating downlink SPS resources.
2. The method of claim 1 , further comprising deactivating any activated downlink SPS resource when an SPS cell radio network temporary identifier (SPS C-RNTI) is changed before the step of reconfiguring the downlink SPS resources in accordance with the downlink SPS resources configuration IE.
3. 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 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 the downlink SPS resources configuration IE is set to enable;
wherein any activated downlink SPS resource is deactivated when the downlink SPS resources are reconfigured; and the downlink SPS resource is activated when receiving a PDCCH signaling for activating downlink SPS resources.
4. The communication device of claim 3 , wherein the process further comprises deactivating any activated downlink SPS resource when an SPS cell radio network temporary identifier (SPS C-RNTI) is changed before the step of reconfiguring the downlink SPS resources in accordance with the downlink SPS resources configuration IE.
5. 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 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 the uplink SPS resources configuration IE is set to enable;
wherein any activated uplink SPS resource is deactivated when the uplink SPS resources are reconfigured; and the uplink SPS resource is activated when receiving a PDCCH signaling for activating uplink SPS resources.
6. The method of claim 5 , further comprising deactivating any activated uplink SPS resource when an SPS cell radio network temporary identifier (SPS C-RNTI) is changed before the step of reconfiguring the uplink SPS resources in accordance with the uplink SPS resources configuration IE.
7. 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 uplink SPS resources in accordance with a uplink SPS resources configuration IE when the uplink SPS resources configuration IE is included in the RRC connection reconfiguration message and the uplink SPS resources configuration IE is set to enable;
wherein any activated uplink SPS resource is deactivated when the uplink SPS resources are reconfigured; and the uplink SPS resource is activated when receiving a PDCCH signaling for activating uplink SPS resources.
8. The communication device of claim 7 , wherein the process further comprises deactivating any activated uplink SPS resource when an SPS cell radio network temporary identifier (SPS C-RNTI) is changed before the step of reconfiguring the uplink SPS resources in accordance with the uplink SPS resources configuration IE.
