The subject matter disclosed herein provides methods and apparatus for providing feedback from a client station to a base station. In one aspect, there is provided a method. The method may align a phase of one or more singular vectors. The singular vectors may each represent one of a plurality of subcarriers of a band. Moreover, an average singular vector may be determined for the plurality of subcarriers of the band, the aligned average singular vector representative of the plurality of subcarriers of the band. The aligned average singular vector may be provided, as feedback, to a precoder at a base station. Related systems, apparatus, methods, and/or articles are also described. |
