Scheduler and scheduling method for transmitting data in mimo based wireless lan system

The present invention relates to a scheduler and a scheduling method of selecting a data transmission time interval and a data transmitting station in a multi-user MIMO system is that, more particularly relates to a mobile communication system. The present invention is a plurality of channels for the wireless channel to the plurality of receive antennas from the respective station, said using the receiver, the received channel measurement signals to receive a channel measurement signal using a plurality of receive antennas from a plurality of stations in consideration of the channel estimation and the number of the plurality of channel state matrices and the plurality of receive antennas for generating a state matrix, and a scheduler for determining the at least one transmitting station from the plurality of stations, the receiver is the transmitting station It provides an access point, characterized in that receiving a data stream from. According to the invention it is possible to take advantage of the characteristics of the MIMO channel to transfer data efficiently. MIMO, multiple input multiple output, scheduler, MAC
