Abstract

A method for performing measurement by a radio apparatus is presented. In one embodiment, the method includes determining raw measurements (e.g., a channel estimation and a noise variance estimation) of a subband and determining a rank indicator (RI) without requiring a precoding matrix indicator (PMI) search. The method includes calculating, based at least on the raw measurements, a mean instantaneous capacity (MIC) for the subband and determining a channel quality indicator (CQI) and a PMI based at least on the MIC. In one embodiment, the method uses subband-based measurements for performing feedback/measurement.
