1. method that is used for sending data in the base station of wireless communication system, this system sends data and use a plurality of antennas multiple-input and multiple-output (MIMO) scheme according to the channel condition information from the terminal feedback, and described method comprises step:

  • Determine that the base station will send data to its terminal, determine in a plurality of antennas, the base station will send the antenna of data via it, and determine the spatial pre-coding method based on channel condition information;

    To transmit data multiplex according to determined antenna amount is a plurality of data flow, and each data flow is carried out coding and modulation;

    Output matrix selects signal, this signal to be used for selecting of a plurality of spatial pre-coding matrixes according to the spatial pre-coding method, and by select matrix that signal selects to each encoded row space coding that flows to based on matrix;

    AndEach is carried out OFDM (OFDM) modulation through the stream of space encoding, and send each stream through the OFDM modulation via associated antennas.
