Abstract
A beam scanning and search tracking method and device are provided. The method includes constructing analog beams and performing digital beam-forming to the analog beams so as to form equivalent beams; transmitting reference signals to a second communication node by using the equivalent beams; receiving beam information about the equivalent beams and corresponding channel state information fed back by the second communication node according to the reference signals; performing a beam scanning operation and a search tracking operation by using the beam information and the channel state information.
