HARQ PROCESS NUMBER MANAGEMENT FOR DOWNLINK CARRIER AGGREGATION

摘要

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.
