The invention proposes an orthogonal random beam forming transmission method based on partial channel information feedback, which comprises the steps: a transmitting terminal transmits pilot signal vector to each receiving terminal which obtains a channel matrix by means of channel estimation; and then singular value decomposition is conducted on the channel matrix and partial channel informationobtained from decomposition is fed back to the transmitting terminal which then determines alternative users and new orthogonal transmitting beams. The transmitting terminal selects a beam from the new orthogonal transmitting beams to send data to a user. The selected user receives a data signal and water filtering is conducted on the data signal. Based on the orthogonal random beam forming proposal and the beam reforming proposal of partial channel information feedback, the method eliminates mutual interference among multi-user beams while having relatively low feedback consumption, thereby greatly improving the capacity of a multi-user system.
