  • Method and node in a wireless communication network
    Patent number: 10084522
    Abstract: Radio network node and method in a radio network node, for wireless communication with a user equipment in a wireless communication system in antenna streams, wherein the radio network node comprises a plurality of antenna elements, forming a multiple antenna array which is configured for massive MIMO transmission. The method comprises beamforming a signal to be transmitted to the user equipment by splitting and phase shifting said signal; detecting a peak of power of one beamformed signal, exceeding a threshold value; manipulating said signal until the peak of power of the signal is lower than said threshold value; and transmitting said signal, to be received by the user equipment.
    Type: Grant
