Abstract

A method can include providing channel feedback to support efficient rank override For example, in such a method, a rank−r precoder index corresponding to a rank−r precoder is determined, and performance for each rank−1 precoder within the rank−r precoder is measured Based on the measured performance, a rank−1 precoder that maximizes performance is selected.
