Abstract: Provided are a transmitter and a method for transmitting a data block in a wireless communication system. The method comprises the following steps: encoding an information bit and generating a block coded with an NCBPSS bit; generating two sub-blocks by parsing the coded block; and transmitting the two sub-blocks to the transmitter. By preventing the bits that are contiguous to the encoding block from having continuous identical reliabilities on a signal constellation, the deterioration of the decoding performance of the transmitter can be prevented.

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 scanning method performed by a station (STA) in a wireless LAN system is provided. The method comprises: transmitting a probe request frame; and receiving a short probe response frame from an access point (AP) as a response to the probe request frame. The short probe response frame includes service set ID (SSID) information or compressed SSID information of the AP.
