METHOD AND DEVICE FOR REALIZING MULTI-INPUT MULTI-OUTPUT

摘要

Disclosed in the present invention is a method for realizing Multi-Input Multi-Output,which comprises the following steps: transmitting a downlink detection channel, Multi-Input Multi-Output (MIMO) control information, and a feedback resource indicator to a Station (STA) from a Central Access Point (CAP); detecting the downlink detection channel to obtain channel information, and feeds back on the feedback resource according to the indication of the MIMO control information by the STA The CAP selects a suitable MIMO pattern for downlink data transmission according to the feedback of the STA. With the present invention, frequency spectrum resources could be dispatched adaptively, and frequency spectrum utilization ratio as well as system performance could be improved.
