The present invention relates to a
beamforming method for finding an optimal communication environment for
wireless communication. According to the present invention, provided is a
beamforming method for preventing
signal loss and reducing
power consumption wherein, in order to solve the problems of conventional
beamforming methods which had the limitation that
signal loss,
delay, and high
power consumption generally occurred during
beam switching and beamforming operations, thereby causing catastrophic errors
in vehicle communication using
millimeter waves, the beamforming method is configured so that a current beam is maintained in an ON state until an optimal beam is found during
beam switching, beamforming is performed after increasing the beam width before performing a beamforming operation, and beamforming is performed by appropriately changing the priorities of a beamforming operation and a
beam switching operation between a
transmitter and a
receiver according to
power consumption, thereby preventing
signal loss that occurs during beam switching and beamforming and improving the safety of vehicle operation, and at the same time reducing the power consumption for vehicle communication, thereby increasing the efficiency of various battery-operated vehicles and mobile devices, such as electric vehicles, autonomous vehicles, and
pedestrian mobility devices in vehicle-to-
pedestrian (V2P) communication, as well as infrastructure for same.
