A method for communicating in a network, the network comprising at least a first cell and a second cell including respectively a first primary station having a first antenna array dedicated to the first cell and a second primary station having a second antenna array dedicated to the second cell, for communicating with a plurality of secondary stations (401, 402), the method comprising the step of: (a) providing with a co-operative beamforming transmission from the first and second primary stations (201, 202) to at least one secondary station, the at least one secondary station receiving at least one spatial stream (301, 302), wherein the step (a) includes: the at least one secondary station signalling to at least one of the first and second primary stations (201, 202) for each spatial stream (301, 302), a first preferred precoding vector for transmission from the first cell and a second preferred precoding vector for transmission from the second cell, and wherein the first preferred precoding vector and the second preferred precoding vector are selected by the at least one secondary station respectively from a first codebook dedicated to the first cell and from a second codebook dedicated to the second cell, a phase relationship between said first and second codebooks being signalled from the at least one secondary station or from the at least one of the first and second primary stations (201, 202); and the first and second primary stations (201, 202) applying a precoding matrix being a precoding vector for each spatial stream across both the first antenna array and the second antenna array, wherein the precoding vector is composed of the first preferred precoding vector and the second preferred precoding vector. (a) providing with a co-operative beamforming transmission from the first and second primary stations (201, 202) to at least one secondary station, the at least one secondary station receiving at least one spatial stream (301, 302), wherein the step (a) includes: the at least one secondary station signalling to at least one of the first and second primary stations (201, 202) for each spatial stream (301, 302), a first preferred precoding vector for transmission from the first cell and a second preferred precoding vector for transmission from the second cell, and wherein the first preferred precoding vector and the second preferred precoding vector are selected by the at least one secondary station respectively from a first codebook dedicated to the first cell and from a second codebook dedicated to the second cell, a phase relationship between said first and second codebooks being signalled from the at least one secondary station or from the at least one of the first and second primary stations (201, 202); and the first and second primary stations (201, 202) applying a precoding matrix being a precoding vector for each spatial stream across both the first antenna array and the second antenna array, wherein the precoding vector is composed of the first preferred precoding vector and the second preferred precoding vector. the at least one secondary station signalling to at least one of the first and second primary stations (201, 202) for each spatial stream (301, 302), a first preferred precoding vector for transmission from the first cell and a second preferred precoding vector for transmission from the second cell, and wherein the first preferred precoding vector and the second preferred precoding vector are selected by the at least one secondary station respectively from a first codebook dedicated to the first cell and from a second codebook dedicated to the second cell, a phase relationship between said first and second codebooks being signalled from the at least one secondary station or from the at least one of the first and second primary stations (201, 202); and the first and second primary stations (201, 202) applying a precoding matrix being a precoding vector for each spatial stream across both the first antenna array and the second antenna array, wherein the precoding vector is composed of the first preferred precoding vector and the second preferred precoding vector.
