Abstract

The present invention refers to methods and an apparatus for transmitting data in a radio communications system, wherein for a multiple downlink transmission of a signal of a Node B, the Node B comprising at least a first antenna and a second antenna, precoding weights are applied for mapping the signal to the first antenna and to the second antenna, with a first precoding weight formula (I) for mapping the signal to the first antenna, and a second precoding weight w 2 for mapping the signal to the second antenna, with w 2 being the first precode or the fourth precode out of a set of four alternative precodes, the set of four alternative precodes being defined as formula (II).
