Abstract:
A method and a device for preventing interference in an overlapping service area are disclosed. The method for preventing interference in an overlapping service area of a wireless LAN can comprise the steps of: receiving, by an interference AP, a beacon frame broadcasted by an AP, wherein the beacon frame includes an interference prevention information element; receiving, by the interference AP, a sounding PPDU indicated on the basis of the interference prevention information element from the AP; determining, by the interference AP, a transmission control matrix on the basis of the sounding PPDU; and transmitting, by the interference AP, data through a beam generated on the basis of the transmission control matrix.
