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 (320) transmits a beamforming weight vector to a user equipment (310) based on a determined channel estimate. The user equipment (310) 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： A base station receiver (610), a computer program product operable at a base station (600), and a method operable at a base station receiver (610), for receiving uplink transmit diversity transmissions utilizing a master / slave scheme at the receiver (610). One or more tracking loops, such as a searcher task, a time tracking loop, or a frequency tracking loop may be implemented at the base station receiver (610) to determine compensation values, such as finger timings for a rake receiver or frequency compensation values, in accordance with characteristics of a primary pilot channel (514) transmitted utilizing a first precoding weight vector. Here, corresponding compensation values may be derived for the reception of a secondary pilot channel (520) transmitted utilizing a precoding weight vector orthogonal to the first precoding weight vector, simply based on those determined for the primary pilot channel (514). That is, the compensation value assignment for receiving the second pilot channel may act as a slave to its master, being the compensation value assignment for receiving the primary pilot channel (514).

摘要： A method, apparatus, processing system, and computer program product enable association of mis-aligned subframes (802) (804) from a first and second downlink (1114) with one another, such that a HARQ acknowledgment message (1116) including jointly encoded feedback for the respective subframes can be correctly interpreted by the corresponding cells. Here, an RNC (1108) may provide an RRC message (1110) to the UE (1102) to associate particular subframes with one another. Further, the RNC (1108) may provide NBAP messages (1112) to the cells (1104) (1106) transmitting the downlink signals, so that the cells can associate the HARQ acknowledgment message (1116) 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： 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 (adding/removing secondary cells at/from) the Active Set for a UE (610). Here, the addition of a cell to the Active Set can coincide with making that cell a secondary serving cell (616) when an event 1A happens. Further, the deletion of a secondary serving cell (616) from the Active Set can coincide with switching off the Multi - Point HSDPA mode when an event IB happens. Still further, a modified mobility event for an HSDPA serving cell change can be utilized to swap a primary serving cell (614) and a secondary serving cell (616).

摘要： In a communication system, user equipment (UE) conditionally performs uplink transmit diversity (ULTD) either by Switched Antenna Transmit Diversity (SATD) or Beamforming Transmit Diversity (BFTD) using a first antenna and a second antenna. Either a serving node or the UE determines that uplink transmit diversity is conditionally authorized. Either a serving node or the UE measures a value. The UE transmits using ULTD in response to determining that an enabling condition based on the value is satisfied. The UE can also disable uplink transmit diversity in response to determining that a disabling condition based on the value is satisfied. The disabling condition comprises a disabling threshold that equals the enabling condition comprising an enabling threshold with a threshold adjustment for hysteresis.
