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