Abstract: PURPOSE: A cooperative multiple cell MIMO(Multiple Input Multiple Output) beam forming and transmitting method based on modified zero forcing is provided to suggest an effective cooperative beam design method in a multi-cell environment including a plurality of antennas. CONSTITUTION: A beam transmitted to user terminals through a modified zero forcing beams forming method is designed(S210). The designed beam is transmitted(S220). The maximum allowable value of interference is set in user terminals in advance. The set maximum allowable value is bigger than 0 or is similar to 0. The allowable value of the interference is set by considering a thermal noise level of the user terminals. [Reference numerals] (S210) Step of designing beams to be transmitted to user terminals through a modified zero forcing beam forming method; (S220) Step of transmitting the designed beams;
