Method for positioning of terminal in telecommunication system operating multiple beams

Disclosed is a position determining method for a terminal in a communication system using multi-beams. An operation method of the terminal in accordance with the present invention comprises a step of receiving a first beam from a first point; a step of receiving a second beam from a second point; and a step of determining the position of the terminal by using information on the first beam and the second beam. The position determining method enables the system using the multi-beams to determine the position of the terminal by using the angle of the beam and beam start and/or final coordinate information without a positioning device such as a GPS when receiving two or more valid beams.
