Abstract
A method for multi-antenna transmission includes allocating a different subcarrier resource or a different code resource to UE-specific reference signals (RSs) corresponding to each beamforming array of multiple beamforming arrays; and using the multiple input multiple output (MIMO) technology on the multiple beamforming arrays. The embodiments of present invention also provide a multi-antenna apparatus and system. Embodiments of the present invention implement combined use of MIMO and the beamforming technology, which brings the advantages of the beamforming technology and MIMO into full play. Therefore, the SNR is improved through the array gain of beamforming arrays to reduce the interference between users, and the channel capacity in the system and the spectrum efficiency are improved through MIMO.
