1. A method, comprising:

  • controlling a plurality of transmission points, which are configured to operate in accordance with a Coordinated Multipoint (CoMP) transmission scheme, to transmit from the plurality of transmission points a same composite Reference Signal (RS) simultaneously with one another, coherently with one another and in the same time-frequency resource elements (REs) to a mobile communication terminal;

    receiving from the terminal feedback, which is estimated in the terminal based on the composite RS that originated simultaneously and coherently from the plurality of the transmission points, the feedback being calculated in the terminal assuming a single-transmission-point transmission, but is indicative of a response of a composite communication channel between the plurality of the transmission points and the terminal; and

    configuring subsequent transmission from the plurality of the transmission points based on the received feedback that was calculated in the terminal assuming the single-transmission-point transmission.
