Abstract: A method of determining a position of a terminal in a communication system using multiple beams is provided. The method includes receiving a first beam from a first point, receiving a second beam from a second point, and determining a position of the terminal by use of information about the first beam and information about the second beam, so that in a case in which two or more effective beams are received in a system using multiple beams, the position of the terminal is determined by use of the angle of a beam, and information about coordinates of departure of a beam and/or coordinates of final arrival of a beam without using a positioning device, such as GPS.

Abstract: A method of estimating a channel of a base station in a communication system using an IRS may comprise: receiving a first signal through a direct path between a terminal and the base station from the terminal and a second signal through an indirect path through the IRS from the terminal; estimating a first angle of arrival of the second signal received from the IRS; estimating a second angle of arrival of a signal transmitted to the IRS by the terminal based on the estimated first angle of arrival; estimating a third angle of arrival of the first signal received from the terminal based on the estimated first angle of arrival; and estimating path gains on the direct path and the indirect path based on the estimated first angle of arrival to the estimated third angle of arrival.
