Abstract

A technique for determining a precoder for a radio transmission via a channel (110) including at least two transmit antennas (106) is disclosed. As to a method aspect of the technique, channel state and optionally channel noise characteristics are measured by a measuring unit (122). Based on a result of the measurement, a subset of precoders is selected out of a codebook (116) including a plurality of precoders by a selecting and determining unit (120). The selecting and determining unit (120) further determines a precoder for precoding the transmission out of the subset.
