Method and apparatus for performing beam search or beam transmission based on location error information in wireless communication system

摘要

One embodiment of the present invention relates to a method for performing a beam search and transmitting a signal in which a first terminal using an mmWave band performs a beam search and transmits a signal in a wireless communication system, comprising the steps of: receiving error information relating to the location of a second terminal; determining at least one of beam direction, beam search performing range, and beam search performing order using the error information for the second terminal; performing a beam search according to the determination that is made; and transmitting a signal to the second terminal through beamforming in accordance with the result of the beam search.
