Abstract
A Tx beamforming method for multi-sector cooperative transmission in a multi-antenna system includes determining a transmission mode of sector boundary users according to a channel condition; determining a multi-sector cooperative Tx beam for supporting multiple users, based on the transmission mode of the user; determining a user combination for multi-sector cooperative beamforming by considering the determined multi-sector cooperative Tx beam; and performing sector cooperative Tx beamforming with the determined user combination. Thus, the overall system capacity can be enhanced.
