Abstract
A method is for realizing Multi-Input Multi-Output which includes steps of: sending, by a Central Access Point, a downlink sounding channel, Multi-Input Multi-Output (MIMO) control information, and a feedback resource indicator to a Station (STA); detecting, by the STA, the downlink detection channel to obtain channel information, and feeding back on the feedback resource according to the indication of the MIMO control information; and selecting, by the Central Access Point, a suitable MIMO mode for downlink data transmission according to the feedback of the STA.
