SCHEDULER AND SCHEDULING METHOD FOR TRANSMITTING DATA IN MIMO BASED WIRELESS LAN SYSTEM

摘要

PURPOSE: A data transmission scheduler in a wireless LAN-system based on multiuser multiple input multiple output for increasing the data receiving performance of an access point is provided to efficiently transmit data by utilizing the characteristics of a MIMO(Multi-Input Multi-Output) channel. CONSTITUTION: A receiving unit(220) receives a channel measurement signal from a plurality of stations through a plurality of receiving antennas(210). A channel estimation unit(230) generates a plurality of channel condition matrixes about a wireless channel through the channel measurement signal from each station to a plurality of receiving antennas. A scheduler(250) selects one or more transmission stations in consideration of the number of a plurality of receiving antennas.
