METHOD FOR BEAMFORMING IN A COOPERATIVE MULTI-CELL MIMO BASED ON ALLEVIATED ZERO-FORCING AND METHOD FOR TRANSMITTING SAME, METHOD FOR ALLEVIATED ZERO-FORCING TRANSMISSION BEAMFORMING USING A SEQUENTIAL ORTHOGONAL PROJECTION COMBINATION ALGORITHM, AND METHOD FOR TRANSMITTING INFORMATION USING SAME

摘要

The present invention relates to a method for beamforming in cooperative multi-cell MIMO based on alleviated zero-forcing and to a method for transmitting same. The method includes the steps of: designing a beam to be transmitted to user terminals through a method for alleviated zero-forcing beamforming; and transmitting the designed beam. In addition, the method for transmitting information according to the present invention includes the steps of: forming a transmission beam through a predetermined equation; and transmitting information using the transmission beam.
