Abstract
Disclosed are a channel access method and an apparatus therefor. A channel access method in a wireless LAN includes the steps of determining whether an STA (station) changes a first access category for a probe request frame; and if a first access category is changed to a second access category, performing a back-off process for enabling the STA to transmit the probe request frame based on the second access category, wherein the second access category may have a lower priority than the first access category.
