摘要:
A method for managing control channel interference is provided. The method includes a first access node performing at least one of blanking and transmitting at lower than nominal transmit power on at least a portion of a control channel. The method further includes the first access node applying at least one of blanking and transmitting at lower than nominal transmit power only on the control region of chosen subframes, wherein a second access node transmits the control region of the chosen subframes at nominal transmit power.
摘要:
A method and apparatus for reconfiguring a user equipment configured for multi-carrier operation from a first downlink control information set to a second downlink control information set while carrier aggregation is being used, including receiving a physical downlink control channel with downlink control information formats containing a carrier indicator field.
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.
摘要:
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).
