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： 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.

摘要： Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, scheduling of the uplink MIMO transmissions may make a determination between single stream, rank=1 transmissions and dual stream, rank=2 transmissions based on various factors. Further, when switching between single and dual stream transmissions in the presence of HARQ retransmissions of failed packets, the scheduling function may determine to transmit the HARQ retransmissions on a single stream transmission or to transmit the HARQ retransmissions on one stream while transmitting new packets on the other stream.

摘要： Systems and methodologies are described that facilitate equalizing inter-sector interference and performing interference cancellation on a forward link by utilizing a combination of pilot interference cancellation followed by selective interference cancellation. Selective interference cancellation can be performed using, for instance, a reduced-rank minimum mean-squared error multi-user detection receiver. A system matrix can be reduced by the combined cancellation protocols, and can be further reduced by performing a fast Hadamard transform there on, which in turn can minimize matrix complexity, as well as computational overhead associated with processing the system matrix.

摘要： Systems and methodologies are described that facilitate pilot channel optimization schemes for high data rate communications transmissions.

In an illustrative operation, an exemplary base station can engage one or more selected pilot channel control operations as part of pilot channel optimization comprising a jump detection technique, operating power control on another channel other than the DPCCH, engaging in delayed power control, engaging in a soft-hand off power control in the instance of a boosted pilot channel, and resolving ambiguity in grant messages resulting from a pilot boost.
