Abstract
Provided are channel sounding and scheduling methods for interference alignment in a wireless LAN. The sounding method includes transmitting a RTS frame, the RTS frame including an OIA candidate AP list that includes identification information of a plurality of access points, transmitting a CTS poll frame for triggering transmission of a CTS frame to a second access point which is a first access point in the OIA candidate AP list, and receiving a CTS frame which is a response to the CTS poll frame from the second access point. Therefore, communication performance of the wireless LAN can be improved.
