Method and apparatus for performing trigger-based operation in wireless LAN system

Abstract

Disclosed are a method and apparatus for performing communication in a wireless LAN system. The method according to an embodiment of the present disclosure comprises the steps of: receiving, by a first station (STA), a trigger frame comprising a plurality of user information fields from a second STA; and on the basis of the trigger frame, transmitting, by the first STA to the second STA on a first 20 MHz channel, a first trigger-based (TB) enhanced long range (ELR) physical layer protocol data unit (PPDU) from among all TB ELR PPDUs, wherein, from among the plurality of user information fields, a first user information field related to the first STA may comprise first information related to the first 20 MHz channel from among all bandwidth channels.
