Claim:
A method for low bit-rate feedback wireless communication system, comprising: obtaining a first set of information; mapping the first set of information to a set of regions; each region of the set of regions represented by a complex number having at least one portion set to a zero value; the at least one portion being selected from a group consisting of an imaginary portion and a real portion; providing a second set of information based upon the first set of information and the mapping of the first set of information to the set of regions; and storing the second set of information for access by at least one component of the wireless communication system; wherein: the set of regions consists of five regions associated with mapping values 0+j0, 1+j0, −1+j0, 0+j1, and 0−j1; the 0+j0 mapping value of the mapping values is associated with a central region of the set of regions; and the central region is a circular region having a diameter.
