  • Beamforming in MIMO radio networks
    Patent number: 10727911
    Abstract: It is provided a method, including decomposing a channel matrix obtained from a reception channel from a sender to a reception antenna array into its singular vectors, wherein the singular vectors include left-singular vectors and right-singular vectors; allocating powers to the right-singular vectors to obtain power-allocated right-singular vectors; identifying maximum antenna gain directions based on a response function of the reception antenna array and all or a subset of the power-allocated right-singular vectors; calculating, for each of the maximum antenna gain directions or a subset thereof, a respective transmission beamforming vector based on a response function of a transmission antenna array; applying the transmission beamforming vectors or a subset thereof to a transmission via the transmission antenna array to the sender.
    Type: Grant
