    摘要: An interference avoidance method performed by an access point (AP) in a wireless local area network (WLAN) system is provided. The method includes: transmitting a training request (TRQ) message for requesting transmission of a sounding frame to a first station which is a target of multi-user multiple input multiple output (MU-MIMO) transmission and a second station which receives data through a direct link during the MU-MIMO transmission; receiving first and second sounding frames respectively transmitted by the first and second stations in response to the TRQ message; estimating a channel by using the first sound frame to determine a beam-forming vector to be used for the MU-MIMO transmission; and performing the MU-MIMO transmission for MU-MIMO transmission target stations including the first station, wherein the beam-forming vector is determined such that the MU-MIMO transmission has a minimum effect on the second station by considering channel information between the AP and the second station and acquired on the basis of the second sounding frame received from the second station.
