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 broadcasting a channel state information reference signal (CSI-RS) is disclosed. A CSI-RS that is orthogonal to CSI-RSs transmitted by each of a first network cell and each of a set of neighbor cells that interfere with the first network cell is identified. In one implementation, the first network cell has a coverage containing a coverage of a second network cell. The method includes transmitting, from the second network cell, the CSI-RS that is orthogonal to CSI-RSs transmitted by each of the first network cell and each of a set of interfering neighbor cells.

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.
摘要:
A method for communicating uplink control information to a base station using a user equipment is presented. The method includes identifying component carriers on the user equipment scheduled for Physical Uplink Shared CHannel (PUSCH) transmissions, and identifying at least one first ranking for each of the component carriers for transmission of uplink control information. Each first ranking is at least partially determined by whether the component carrier is configured for delay-sensitive transmissions. The method includes using the at least one first ranking to select a first component carrier for transmission of uplink control information, and encoding uplink control information into the first component carrier for transmission to the base station.

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 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 during a first time interval. The control information allocates a resource on at least one of the first communication carrier and the second communication carrier. When the control information allocates a resource on the first communication carrier, the method includes receiving data using the first communication carrier during a second time interval. When the control information allocates a resource on the second communication carrier, the method includes receiving data using the second communication carrier during a third time interval, the third time interval being offset from the first time interval.
摘要:
A system and method of receiving a channel state information reference signal (CSI-RS) is presented. At a user equipment, a first CSI-RS transmitted from a base station is received. In some implementations, the first CSI-RS is transmitted at a first periodicity using a first set of antenna ports. At the user equipment, a second CSI-RS transmitted from the base station is received. In some implementations, the second CSI-RS is transmitted at a second periodicity using a second set of antenna ports. At least one of the first CSI-RS and the second CSI-RS is used to perform channel measurement.
