Abstract:
1. A method that facilitates generating feedback related to a forward link channel for linear precoding, comprising: estimating a forward link channel to generate a matrix; modifying matrices from a codebook to obtain a set of tailored matrices corresponding to a modified codebook, wherein the matrices from the codebook are modified at least in part based upon implicit channel related information provided via a reverse link channel; quantizing a portion of the matrix to yield explicit feedback, wherein quantizing comprises comparing the matrix with the set of tailored matrices from the modified codebook to identify a closest tailored matrix; and transmitting quantized data over a reverse link channel that provides implicit feedback corresponding to a remainder of the matrix, wherein the implicit feedback is not identical to the explicit feedback, and wherein the implicit feedback provides information about a part of the matrix other than the quantized portion.
