  • Patent number: 8848641
    Abstract: 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.

  • Publication number: 20140254521
    Abstract: A system and method for configuring a component carrier is presented. A component carrier assignment message is received. The component carrier assignment message may be configured to identify the component carrier and include at least one of, at least one of a downlink carrier frequency, a carrier frequency of a paired uplink carrier, a bandwidth of the component carrier, and a bandwidth of the paired uplink carrier, an indication of whether the component carrier is a control channel monitoring component carrier configured to signal data channel assignment information for the component carrier, and a logical index of the component carrier. The component carrier assignment message may then be used to configure the component carrier on a user equipment (UE).
