FEEDBACK FOR SUPPORTING SU-MIMO AND MU-MIMO OPERATION IN WIRELESS COMMUNICATION

摘要

A method, an apparatus, and a computer program product for wireless communication are provided in which a precoding matrix is determined from a set of precoding matrices with a first throughput based on a reference signal. In addition, a subset of precoding matrices is determined from the set of precoding matrices with a second throughput greater than a fraction of the first throughput based on the reference signal. Furthermore, a precoding matrix is selected from the subset of precoding matrices based on a metric.
