Claim One:
1. A method that facilitates controlling transmission in response to feedback in a wireless communication system, comprising: using a set of unitary matrices, each of the unitary matrices being based upon a diagonal matrix and a Discrete Fourier Transform (DFT) matrix, wherein the set of unitary matrices includes a first cluster of unitary matrices, the first cluster of unitary matrices including a subset of the set of unitary matrices; identifying a selected unitary matrix from the set of unitary matrices based upon a received index, wherein the selected unitary matrix corresponds to a channel unitary matrix derived by a mobile device from forward link channel estimations; determining whether the selected unitary matrix is included in the first cluster of unitary matrices; and modifying transmission over the forward link channel based upon the selected unitary matrix being included in the first cluster of unitary matrices; wherein the modifying transmission over the forward link channel further comprises utilizing substantially equal transmission power for each transmit antenna based upon the selected unitary matrix.
