Scheduling method with zero-forcing beamforming in mimo wireless systems

The present invention relates to the limited radio resources when a plurality of users present in the MIMO system for transmitting and receiving signals between a plurality of transmit antennas and multiple receive antennas to a scheduling method for efficiently allocated to each user. A plurality of transmitting antennas and at multiple receiving antennas (MIMO) system for transmitting and receiving signals between a plurality of receiving antennas by selecting the user as much as the number of the plurality of transmit antennas at the transmitting end among a plurality of users each time every transmission zero-forcing beamforming (zero using beamforming -forcing) simultaneously transmits a signal. In this time, the transmitting end to select the user with the information about the state of channels in choosing a user using a greedy method having a level lower complexity of the possible practical (greedy method) having the orthonormal one (orthonormal) channel vector and it transmits the data. This, according to the present invention will practically implemented by using a scheduling algorithm with the complexity of the possible levels distributed fairly limited radio resources to each user it is possible to improve the transmission capacity of the entire system at the same time.
