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.
Claims8
A channel access method in a wireless local area network (WLAN), the method comprising:
- determining whether a station (STA) changes a first access category for a first probe request frame based on whether a second probe request frame is received from another STA during a probe delay duration for the first probe request frame before a backoff procedure by the STA;
- if the second probe request frame is received during the probe delay duration, changing the first access category to a second access category,
- wherein the second access category has a lower priority than the first access category;
- and
- performing the backoff procedure by the STA to transmit the first probe request frame based on the second access category.
A STA performing a channel access in a wireless local area network (WLAN), the STA comprising:
- a radio frequency (RF) unit configured to transmit a radio signal;
- and
- a processor operatively connected to the RF unit and configured to:
- determine whether a station (STA) changes a first access category for a first probe request frame based on whether a second probe request frame is received from another STA during a probe delay duration for the first probe request frame before a backoff procedure by the STA,
- if the second probe request frame is received during the probe delay duration, change the first access category to a second access category,
- wherein the second access category has a lower priority than the first access category, and
- perform the backoff procedure by the STA to transmit the first probe request frame based on the second access category.
