    Abstract: Disclosed are a method and an apparatus for the discovery of a sector in a wireless LAN system. A method for the discovery of a sector by an access point (AP) in a wireless LAN system comprises: a step of setting sector beacon intervals in which the AP of the wireless local area network system transmits a sector beacon to any one sector from among a plurality of spatially divided sectors, and an omni beacon interval in which the AP transmits an omnidirectional beacon to the one sector; a step of transmitting a sector beacon to any one current sector from among the plurality of sectors; a step of transmitting, to the current sector, a transmission frame indicating a sector transmission or a transmission frame indicating an omnidirectional transmission in the sector interval between the sector beacon intervals; and a step of receiving, from the terminal located in the current sector, a response frame indicating that the transmission frame indicating the sector transmission is received and an association is made.

    Abstract: A variable transmission method according to a subcarrier in a multiple input multiple output is provided to determine a subcarrier modulation method flexibly in a wireless channel environment by applying a modulation method to each subcarrier by using a CN(Condition number) that is channel information. The CN that is the channel information is calculated(401). A subcarrier modulation method is determined according to the CN value(402). The CN is obtained by changing the roles of a transmitting terminal and a receiving terminal. The CN is a value obtained by dividing the maximum value of a singular value of a diagonal matrix by the minimum value.
