Abstract: A method of positioning a terminal includes: receiving a first radio signal generated through beamforming from a base station; obtaining a cell ID and a beam ID from the first radio signal; obtaining a received signal intensity of the first radio signal; and estimating a first position of the terminal by comparing a fingerprint in which a cell ID, a beam ID, and a received signal intensity are mapped to each point on a map with the cell ID, the beam ID, and the received signal intensity obtained from the first radio signal.
