摘要： A method for communicating channel state information (CSI) to a base station is presented. The method includes identifying a number of allocated resources for CSI within at least one of a Physical Uplink Control CHannel (PUCCH) payload and a Physical Uplink Shared CHannel (PUSCH) payload. The method includes encoding channel state information (CSI) for activated carriers on a user equipment into the allocated resources for CSI. When a number of activated carriers on the user equipment is less than the number of allocated resources for CSI, the method includes using repetition encoding to duplicate the CSI for at least one of the activated carriers on the user equipment into the allocated resources for CSI.

摘要： A method for receiving data using a user agent (UA) configured to communicate with a wireless communications network using a first and second communication carrier is presented. The method includes receiving control information at a first time interval using the first communication carrier. The control information allocates a resource on at least one of the first communication carrier and the second communication carrier. The control information indicates whether a carrier switch is required. In one implementation, when the control information indicates a carrier switch is required, the method includes ceasing signal reception on the first communication carrier, and receiving a signal on the second communication carrier.

摘要： A system and method for radio link failure recovery is presented. A set of component carriers is identified. Each one of the set of component carriers includes a control channel monitored by a user equipment (UE). The control channel signals data channel assignment information for the UE. Radio link failure recovery is performed using monitoring of only a subset of the set of component carriers. In some cases, performing radio link failure recovery includes performing radio link failure detection, and detecting radio link failure by detecting an out-of-sync condition on a downlink physical layer, the out-of-sync condition occurring for a predetermined duration. In some cases, a number of component carriers in the subset of the set of component carriers is equal to 1.
