Abstract
A MU-MIMO method of an access point in a WLAN using multi-channels and having at least one station includes: receiving index information indicating a precoding vector for a beam selected by the station and channel quality information thereof for each one of the multi-channels; generating first channel capacity information of channel combination groups using the channel quality information wherein the channel combination groups are grouped according to a predetermined channel bandwidth of the multi-channels; and allocating resources to the station from a channel combination selected from the channel combination groups according to the first channel capacity information using the index information and the channel quality information, wherein the access point and the station previously store precoding vector information for a plurality of beams for the MU-MIMO.
