1. A method of operating a terminal comprising:
determining errors between each of channel values measured through each of a plurality of beams of the terminal and each of preset channel values for each of the plurality of beams corresponding to a candidate angle;
determining an angle difference between an angle of a beam determined among the plurality of beams through beam training with another terminal and the candidate angle; and
determining an angle for the other terminal among a plurality of candidate angles including the candidate angle based on the angle difference and the errors.
