Method and apparatus for a component carrier deactivation timer in a wireless communication system
A method for a Component Carrier (CC) deactivation timer in a wireless communication system includes receiving a first Medium Access Control (MAC) Control Element (CE) for CC Management to activate a first Secondary CC (SCC) that has been already activated by using a second MAC CE for CC Management. The method then includes restarting a deactivation timer for the first SCC based upon the first MAC CE for CC Management.
1. A method for a Component Carrier (CC) deactivation timer in a wireless communication system, comprising:
receiving a first Medium Access Control (MAC) Control Element (CE) for CC Management to keep activating a first Secondary CC (SCC) that has been already activated by using a second MAC CE for CC Management; and
restarting a deactivation timer for the first SCC upon receipt of the first MAC CE to keep activating the first SCC.
2. The method of claim 1 , wherein the deactivation timer for the first SCC that has been already activated is restarted when the first MAC CE for CC Management is received on a second SCC that is different from the first SCC.
3. The method of claim 1 , wherein the first SCC is originally activated with activation command signal carried by a MAC CE for CC Management.
4. The method of claim 1 , wherein the deactivation timer is started when the first SCC is first activated.
5. The method of claim 1 , wherein the first SCC is deactivated when the deactivation timer expires.
6. A method for a Component Carrier (CC) deactivation timer in a wireless communication system, comprising:
activating a first Secondary Component Carrier (SCC) by receiving a first Medium Access Control (MAC) Control Element (CE) for CC Management carrying an activation signal for the first SCC;
starting a deactivation timer for the first SCC when the first SCC is activated;
receiving a second MAC CE for CC Management on a Primary CC (PCC) or a second SCC that is different from the first SCC to keep activating the first SCC which is already activated; and
restarting the deactivation timer for the first SCC upon receipt of the second MAC CE to keep activating the first SCC.
7. The method of claim 6 , wherein the first SCC is deactivated when the deactivation timer expires.
8. A user equipment (UE) for a wireless communication system, the UE comprising:
a control circuit for realizing functions of the UE;
a processor installed in the control circuit, for executing a program code to command the control circuit; and
a memory installed in the control circuit and coupled to the processor;
wherein the processor is configured to execute a program code stored in memory to receive a first Medium Access Control (MAC) Control Element (CE) for Component Carrier (CC) Management to keep activating a first Secondary CC (SCC) that has been already activated by using a second MAC CE for CC Management, and restart a deactivation timer for the first SCC upon receipt of the first MAC CE to keep activating the first SCC.
9. The UE of claim 8 , wherein the deactivation timer for the first SCC that has been already activated is restarted when the first MAC CE for CC Management is received on a second SCC that is different from the first SCC.
10. The UE of claim 8 , wherein the first SCC is originally activated with a MAC CE for CC Management.
11. The UE of claim 8 , wherein the deactivation timer is started when the first SCC is first activated.
12. The UE of claim 8 , wherein the first SCC is deactivated when the deactivation timer expires.
