ANTENNA CONFIGURATION FOR COOPERATIVE BEAMFORMING Russian patent published in 2015 - IPC H04B7/06 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to network communication, such as mobile communication. The invention particularly discloses a method for communication over a network, which comprises a first cell and a second cell respectively including 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, the method comprising a step of providing cooperative beamforming transmission from the first and second primary stations to at least one first secondary station, the step including: first secondary station signalling at least one channel matrix to at least one of the first and second primary stations, and the first and second primary stations applying a precoding matrix to both the first antenna array and the second antenna array, and wherein the precoding matrix comprises a first vector for the first cell and a second vector for the second cell, the precoding matrix being based on the at least one channel matrix.

EFFECT: providing codebooks which can be used for beamforming.
