ABSTRACT:
A first signal containing first data multiplied by a first weight factor is transmitted from a first radio station to a first terminal. The first weight factor is calculated taking into account a second weight factor to be used by a second radio station for transmission of a second signal containing the first data multiplied by the second weight factor, such that simultaneous reception of both the first signal and the second signal at the first terminal will cause the first data to be substantially cancelled. Further, the first weight vector is calculated taking into account first and second channel state information received from the first terminal.
