Abstract
Culling a set of precoders down to a smaller set using a comparatively simple first-pass evaluation allows a wireless device or other entity to reduce an overall computational burden associated with identifying a currently preferred precoder. An example approach involves selecting a reduced set of precoders from a full set of precoders, based on performing preliminary evaluations of precoders in the full set, and selecting a preferred precoder or precoders from the reduced set, based on performing further evaluations of precoders in the second set. On a per precoder basis, the further evaluations are more complex than the preliminary evaluations. One may view the approach as using less complex first-pass evaluations to reduce the precoder search space, and then using more complex second-pass evaluations to identify a currently preferred precoder or precoders within the reduced search space.
