HARQ process number management for downlink carrier aggregation
First Claim
1. A method comprising:
- receiving, by a user agent supporting multiple carriers in a wireless communication network, afirst 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.

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.

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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

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.
