摘要： A method for data transmission is disclosed. The method includes: performing, by a system, resource element mapping on modulation symbols which include data to be transmitted and reference signals and which are allocated to antenna ports of a designated type; performing antenna port mapping on the modulation symbols which are through the resource element mapping; and generating Orthogonal Frequency Division Multiplexing (OFDM) signals based on the modulation symbols which are through the antenna port mapping and transmitting the OFDM signals via physical antennas. The present invention also discloses an apparatus for data transmission. In the method and apparatus provided by the present invention, through establishing a mapping relationship between physical antenna elements and antenna ports, beamforming weights are added to modulation symbols of users at the same time. Thus, beamforming operation of the users is implemented. Accordingly, the system may support flexible beamforming transmission on frequency-domain, which greatly improves the flexibility of data transmission of the system.
