In a method for determining a precoding matrix for precoding symbols to be transmitted to a plurality of wireless devices by a node of a wireless communication system the precoding matrix comprises a precoding vector for each wireless device of a plurality of wireless devices, each precoding vector having a precoding element for each transmit antenna of the node. Each precoding element represents a phase shifter for phase shifting a phase of a symbol to be transmitted. A plurality of interference strength indicators for different phase angles is calculated based on the precoding matrix. Further, for the precoding element of the precoding vector a phase angle is selected which corresponds to a calculated interference strength indicator fulfilling a predefined interference strength criterion. |
