Abstract
A method for designating, by a user agent supporting multiple carriers in a wireless communication network, one assigned carrier as an anchor carrier, at least one assigned carrier as an inactive carrier, and at least one assigned carrier as an active carrier. The method can also include receiving a command from an enhanced node B causing a first carrier to transition from an inactive carrier to an active carrier. Additionally, the method can include responsive to reception of the command, monitoring a control channel corresponding to the first carrier. Further, the method can also include receiving downlink control information (DCI) via the control channel. The method can also include responsive to reception of the DCI, starting a timer, and deactivating the first carrier at the expiration of the timer.

Claim
1. A method comprising:
receiving, by a user agent supporting multiple carriers in a wireless communication network, a
first message from a base station, the first message indicating that a carrier has to be activated as an anchor carrier, receiving a second message from the base station, the second message indicating at least two carriers other than the anchor carrier that are to be assigned as non-anchor carriers, receiving a third message from a base station, the third message indicating at least two indicated carriers from the at least two assigned carriers other than the anchor carrier that are to be activated, wherein activating the indicated carriers comprises monitoring a control channel of each indicated carrier;
starting a timer relative to each indicated carrier; and
when the timer relative to a first carrier of the indicated carriers expires, deactivating the first carrier, the deactivating comprising ending the monitoring of a control channel of the first carrier and not deactivating other carriers of the indicated carriers.
2. The method of claim 1, further comprising:
restarting, by the user agent, the timer related to the first carrier when a packet is received on the first carrier.
3. The method of claim 2, further comprising receiving downlink control information (DCI) via the control channel, wherein the DCI allocates resources to the user agent.
4. The method of claim 3, wherein the packet includes a hybrid automatic repeat request (HARD) process indicator (HPI).
5. The method of claim 1, wherein the control channel is a physical downlink control channel (PDCCH).
6. The method of claim 1, further comprising monitoring, by the user agent, a control channel of the anchor carrier of the multiple carriers, wherein the anchor carrier is the only carrier routinely monitored by the user agent.
7. The method of claim 1, wherein the timer relative to a second carrier of the indicated carriers expires, deactivating the second carrier, the deactivating comprising ending the monitoring of a control channel of the second carrier.
8. The method of claim 7, further comprising continuing monitoring of the anchor carrier.
9. The method of claim 1, wherein the expiry of the timer relative to the first timer causes the first carrier to be designated as deactivated.
10. The method of claim 1, wherein the user agent is one of: a wireless handset, a pager, a personal digital assistant, a portable computer, a tablet, a laptop computer, a mobile phone, a telecommunications device, a set-top box, a network node and a desktop computer.
11. A user agent for use in a wireless communication network, the user agent comprising:
a processor; and
a communications subsystem,
wherein the user agent is configured to:
receive first message from a base station, the first message indicating that a carrier has to be activated as an anchor carrier, receive a second message from the base station, the second message indicating at least two carriers other than the anchor carrier that are to be assigned as non-anchor carriers, receive a third message from a base station, the third message indicating at least two indicated carriers from the at least two assigned carriers other than the anchor carrier that are to be activated, wherein activating the indicated carriers comprises monitoring a control channel of each indicated carrier;
start a timer relative to each indicated carrier; and
when the timer relative to a first carrier of the indicated carriers expires, deactivating the first carrier, the deactivating comprising ending the monitoring of a control channel of the first carrier and not deactivating other carriers of the indicated carriers.
12. The user agent of claim 11, wherein the user agent is further configured to:
restart the timer related to the first carrier when a packet is received on the first carrier.
13. The user agent of claim 12, further comprising receiving downlink control information (DCI) via the control channel wherein the DCI allocates resources to the user agent.
14. The user agent of claim 11, wherein the packet includes a hybrid automatic repeat request (HARD) process indicator (HPI).
15. The user agent of claim 11, wherein the control channel is a physical downlink control channel (PDCCH).
16. The user agent of claim 11, wherein the user agent is further configured to monitor a control channel of the anchor carrier of the multiple carriers, wherein the anchor carrier is the only carrier routinely monitored by the user agent.
17. The user agent of claim 11, wherein the timer relative to a second carrier of the indicated carrier expires, deactivating the second carrier, the deactivating comprising ending the monitoring of a control channel of the second carrier.
18. The user agent of claim 17, wherein the user agent is further configured to continue monitoring of the anchor carrier.
19. The user agent of claim 11, wherein the expiry of the timer relative to the first timer causes the first carrier to be designated as deactivated.
20. A non-transitory computer readable medium having instructions stored thereon for execution by a processor of a user agent, the instructions comprising code for:
receiving, by the user agent supporting multiple carriers in a wireless communication network, a
first message from a base station, the first message indicating that a carrier has to be activated as an anchor carrier, receiving a second message from the base station, the second message indicating at least two carriers other than the anchor carrier that are to be assigned as non-anchor carriers, receiving a third message from a base station, the third message indicating at least two indicated carriers from the at least two assigned carriers other than the anchor carrier that are to be activated, wherein activating the indicated carriers comprises monitoring a control channel of each indicated carrier;
starting a timer relative to each indicated carrier; and
when the timer relative to a first carrier of the indicated carriers expires, deactivating the first carrier, the deactivating comprising ending the monitoring of a control channel of the first carrier and not deactivating other carriers of the indicated carriers.
