Abstract: Disclosed is a cellular communication system allowing direct communication between terminals within a cell or simultaneous transmission and reception of signals between a base station and the terminals through a repeater to be made by introducing a universal link, and a communication method thereof. The communication method of the cellular communication system includes: transmitting, by a base station, universal link setting information and a transmission control signal to a first terminal within a cell, transmitting, by the base station, the universal link setting information and a reception control signal to a second terminal within the cell, and directly transmitting/receiving, by the first and second terminals, signals through the universal link.

Abstract: A positioning method using images and radio waves may include: estimating a distance and an angle from the positioning reference node to a positioning target terminal; identifying an obstacle or reflective object in a vicinity of the positioning target terminal or on a path between the positioning target terminal and the positioning reference node by using image information on the positioning target terminal at a position estimated by the distance and the angle; estimating an incident angle or a reflection angle of a radio wave signal reflected by the reflective object identified based on the image information; and estimating a position of the positioning target terminal based on the reflection angle and the distance.

Abstract: A method of connecting base stations by a one-way cooperative channel forming a beam is provided. Since it is possible to determine directions of beams and to distribute power components by small amounts of calculations, it is possible to realize the base stations in a one-way cooperative situation with small expenses. In addition, the base stations according to the exemplary embodiment of the present invention may minimize the influence of interference generated by signals transmitted by other base stations through the one-way cooperative channel and the influence of interference generated by signals transmitted to other terminals.
