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： Methods and apparatus for control signaling in a communication system using continuous valued measurement and feedback are disclosed. The control signaling utilizes delta-sigma modulation where a measured phase or amplitude of a received signal is used to determine a difference signal by subtracting a previously quantized integrated difference signal from the current measurement signal, and then integrating the difference signal. The integrated difference signal is quantized and transmitted to the device originating the received signal as feedback control signaling. The device originating the received signal may then filter the control signaling to obtain the desired control information used to adjust or control the transmission of the signal transmitted by the device. By utilizing delta-sigma modulation, a greater degree of control signaling precision is achieved when controlling variables such as phase or amplitude of the transmitted signals, thereby achieving improved communication system performance.
