    摘要： An apparatus, method, and computer program product operable to determine a phase of a beamforming weight vector utilizing a memory of a previously used phase for the beamforming weight vector, capable of improving a channel estimate. A base station transmits a beamforming weight vector to a user equipment based on a determined channel estimate. The user equipment selects between the received beamforming weight vector, or a modified beamforming weight vector having its phase shifted by −360°, in accordance with a suitable selection criteria. That is, the selection is made such that a difference between the phase of the selected beamforming vector and a phase of a prior beamforming vector is within a predetermined range.

    摘要： Systems and methods to configure and schedule asymmetric carriers on an uplink between communication devices are described herein. An access node is provided to reserve a common-channel-free carrier for communication with an access terminal. The access node may reserve the carrier for communication with the access terminal based on path loss data between the access node and the access terminal. Further, an adaptive rise-over-thermal (RoT) target may be employed for communication over any carrier.

    摘要： A method, apparatus, processing system, and computer program product enable association of mis-aligned subframes from a first and second downlink with one another, such that a HARQ acknowledgment message including jointly encoded feedback for the respective subframes can be correctly interpreted by the corresponding cells. Here, an RNC may provide an RRC message to the UE to associate particular subframes with one another. Further, the RNC may provide NBAP messages to the cells transmitting the downlink signals, so that the cells can associate the HARQ acknowledgment message with the appropriate subframe. Still further, additional signaling provides for changing the set of associated subframes when needed due to a drift in the timing offset between cells.

    摘要： A method of wireless communication includes utilizing a first outer loop for single-stream transmissions when a requested PCI by a UE is within a first set. The utilizing the first outer loop includes utilizing a first outer loop margin to adjust a size of a transport block by a first backoff margin when the UE requests a PCI within the first set. The method further includes utilizing a second outer loop for single-stream transmissions when the requested PCI by the UE is within a second set different from the first set. The utilizing the second outer loop includes utilizing a second outer loop margin to adjust the size of the transport block by a second backoff margin when the UE requests a PCI within the second set.

    摘要： A method and apparatus for wireless communication may provide for mobility in a Multi-Point HSDPA network capable of downlink aggregation. Some aspects of the disclosure provide modified mobility events utilized for altering the Active Set for a UE. Here, the addition of a cell to the Active Set can coincide with making that cell a secondary serving cell. Further, the deletion of a secondary serving cell from the Active Set can coincide with switching off the Multi-Point HSDPA mode. Still further, a modified mobility event for an HSDPA serving cell change can be utilized to swap a primary serving cell and a secondary serving cell.
