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.

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).

A method for processing a control channel at a user agent (UA) to identify at least one of an uplink and a downlink resource allocated by a resource grant within a multi-carrier communication system wherein resource grants are specified by control channel element (CCE) subset candidates wherein the carriers used for data transmission and reception are configured carriers, the method comprising the steps of receiving activation signals specifying active and deactivated carriers from among the configured carriers, for active carriers (i) identifying a number of CCE subset candidates to decode and (ii) decoding up to the identified number of CCE subset candidates in an attempt to identify the resource grant; and for deactivated carriers, ignoring CCE subset candidates associated with the deactivated carriers.

Methods, devices, and systems for multi-carrier network operation are disclosed. In one embodiment, a method of performing channel scrambling in a multi-carrier network, wherein the multi-carrier network includes a first component carrier (“CC”) and a second CC between a base station and a user equipment (“UE”) comprises receiving a Cell Radio Network Temporary Identifier (“C-RNTI”) and a cell identification (“ID”) for at least one of the first CC and the second CC; and using the RNTI and the cell ID to perform scrambling of information transmitted on at least one of the first CC and the second CC.

A method and apparatus of signaling radio resource allocation in a wireless communication system includes transmitting at least one region boundary to a mobile station indicating a division of the time-frequency resources into at least two regions, determining a time-frequency resource assignment for the mobile station, transmitting an indication of the determined time-frequency resource to the mobile station in the same region as the determined time-frequency resource, and transmitting a packet to the mobile station using the physical time-frequency resources corresponding to the determined time-frequency resource.

A method in a base station of transmitting control information to a mobile station includes transmitting a persistent assignment to a mobile station, wherein the persistent assignment includes a plurality of ACID indications; and transmitting a subsequent assignment to the mobile station including an ACID derived from the plurality of ACID indications. In another method, a mobile station receives control information from a base station, including receiving a persistent assignment from the base station, wherein the persistent assignment includes a plurality of ACID indications; and receiving a subsequent assignment from the base station including an ACID derived from the plurality of ACID indications.

A system and method for partitioning and transmitting a frame configuration in a wireless communication system is provided. A preferred embodiment comprises a method for determining a frame configuration in H-FDD systems where multiple time domain groups are supported is disclosed. Another embodiment provides a method for a base station for transmitting an indication of a frame configuration in H-FDD systems where multiple time domain groups are supported. Further, if the mobile stations enter into an error condition because they did not receive the frame configuration, an error recovery process may be utilized to self-recover from the error condition.
