The antenna selection method and apparatus for data transmission mode

The present invention discloses a method and apparatus for selecting an antenna transmission mode data. In the above method, the transmitting end according to the channel state information from the spatial diversity beamforming and spatial multiplexing with cyclic delay diversity mode determining adapted to receive an end of the data transmission mode; and a transmission side using the determined data transmission mode to transmit data. According to the present invention provides, to solve the related art due to a lack of space diversity beamforming and spatial multiplexing with cyclic delay diversity to select a data transmission mode of embodiment, not in accordance with the system channel conditions flexibly selected data transmission mode to the spatial diversity beamforming and spatial multiplexing with cyclic delay diversity for data transmission. With the above technical solutions, to increase the stability and improve the throughput of the link system.
