1. A beamforming selection method of a first wireless communication node, the method comprising:
receiving first reference signaling, transmitted from a second wireless communication node using a first beamforming setting;
generating a first channel estimate based on the first reference signaling;
transmitting, using a second beamforming setting, second reference signaling for reception by the second wireless communication node, wherein each coefficient of the second beamforming setting represents a complex conjugate of a corresponding component of the first channel estimate; and
receiving final reference signaling, transmitted from the second wireless communication node;
generating a final channel estimate based on the final reference signaling; and
selecting a beamforming setting for communication, wherein each coefficient of the selected beamforming setting for communication represents a complex conjugate of a corresponding component of the final channel estimate.
