摘要:
A method is disclosed that includes selecting one or more terminals involved in a device-to-device communication to which interference caused by a transmission to one or more other terminals should be suppressed, and choosing a number of degrees of freedom from a predetermined number of degrees of freedom to be used to suppress interference towards the selected one or more terminals. The method also includes using the remaining degrees of freedom from the predetermined number to increase signal quality to the one or more other terminals and performing precoding based on the chosen number of degrees of freedom and the remaining degrees of freedom. The method further includes, using at least the performed precoding, transmitting information to the one or more other terminals. Apparatus and programs/program products are also disclosed.
