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： A base station receiver, a computer program product operable at a base station, and a method operable at a base station receiver, for receiving uplink transmit diversity transmissions utilizing a master/slave scheme at the receiver. 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 to determine compensation values, such as finger timings for a rake receiver or frequency compensation values, in accordance with characteristics of a first received pilot channel transmitted utilizing a first precoding weight vector. Here, corresponding compensation values may be derived for the reception of a secondary pilot channel transmitted utilizing an precoding weight vector orthogonal to the first precoding weight vector, simply based on those determined for the first pilot channel.
