Abstract

Provided is a method for data stream transmission in a multiple input multiple output (MIMO) system wherein each data stream maps to a plurality of layers in a MIMO channel space for transmission. The method comprises: interlayer interleaving N data streams obtaining N post interleaved data streams; mapping said N post interleaved data streams onto N layers respectively in the MIMO channel space and sending said data streams. Use of the method of the present invention enables better use of joint CQI to improve MIMO transmission performance while interference cancellation technologies (such as SIC techniques) are used on the basis of interlayer interleaving to eliminate the impact of interlayer interference.
